    A flowline connector device for subsea well operations in which a connector means on the end of the flowline is moved laterally into position for connection to a fixed connector means on a subsea station. The connector means on the subsea station includes an axially movable mandrel located within a chamber in a body member, the mandrel having sealing surfaces at one end thereof juxtaposed to sealing surfaces on the flowline connector member when laterally positioned. A fluid pressure actuated locking means moves said sealing surfaces on the mandrel into sealed relationship with the sealing surfaces on the flowline connector member and locks the sealing surfaces in fluid tight sealed relation. A mechanical backup lock means for the mandrel is carried by the connector means on the subsea station for positively and unyieldingly mechanically locking the mandrel in fluid tight sealed relation. In the event of a drop in fluid pressure, leakage at the sealing surfaces is prevented by the mechanical locking device.

    A device for connecting pipes containing a connecting element into which the connected ends of the pipes are introduced by their axial movement (1) is known.
    However, under some underwater conditions, it is difficult to axially move the system installed on the seabed because of the weight of the system, possible settlement of the latter on the seabed, or because of the friction resistance of the system on that bottom. In submarine stations, it is difficult to install the appropriate ends of the systems for their connection with precise axial alignment; poor axial embossing conditions may interfere with proper jointing and tight seal in the joint zone.
    A device for connecting pipes, including a connecting element with a hydraulic piston locking system and sealing / two connected pipes [2].
    A disadvantage of the known device.
    , consists in the fact that the connection of two pipes is carried out by pre-supplying the end of one of the pipes to be connected with a funnel, and various types of sealing are carried out using classic devices in the form of washers, inclined planes and locking elements that are installed in place.
    The purpose of the invention is the provision of 15 faster and more tight pipe connections.
    This goal is achieved in that in a device for connecting pipes, including a connecting element with a hydraulic piston system for locking and sealing two connected pipes, the connecting element is made with two grooves, the first of which is located on its 25 lateral surface, and the other on the end, one of the pipes to be connected is equipped with a head, the dimensions of which correspond to the side groove of the connecting element with a sealing surface on the end part and an annular groove, the dimensions of which correspond Allen groove connecting member and the other pipe is mated with the socket on the end of it and placed in the gasket. 5
    In addition, the device can be equipped with a blocking clutch installed with the possibility of translational movement in the connecting element, rigidly mounted on the pipe with a socket on the end, an annular mandrel installed in the end part of the coupling, an annular piston installed between the pipe, the clutch and the annular mandrel, a spring placed in sockets made in adjacent ends of the mandrel and piston, and a latch located with the possibility of translational movement in the connecting element on the end of the blocking clutch, and the connecting element is formed an annular slot for the latch.
    In FIG. 1 shows a device for connecting pipes with a connecting element fixed to an underwater station and a part of the end of the connecting element placed at the end of the piping system AND separated from the corresponding element of the underwater station, general, partial view, FIG. 2 - a device for connection, the connecting element of which and the element fixed on the underwater station are in the locked and impermeable position, section (on an enlarged scale), in FIG. 3 - locking device, partial section (shown driving in the direction of the opening position); and 4Q of FIG. 4 is a blocking device in the open position, a partial section, in FIG. 5 is a blocking device at the same time in hydraulic and mechanically open positions, partial section, in FIG. 6, section AA in FIG. 2 (a mechanical locking device in the 'locked' position, the pipe of the fluid pumping piping system u under pressure being removed for greater, 50 clarity of the figure).
    The pipe connecting device 1 comprises a pipe to be connected 2 and a connecting element 3 mounted on a submarine station. The connected tyub 2 is fixed at the end of the piping system, which can be placed on the seabed and stretches from the underwater well to the underwater 60 of station 4 having element 3. Only part of station 4 is shown in the figure, namely, two vertical guiding beams 5, which are fixed, for example, on the skeleton of an underwater station. 65
    The connecting element 3 can be supported and supported horizontally by side pipes 6, which carry at their ends connecting cylindrical couplings 7 for installing guide beams 5.
    The connected pipe 2 has a cylindrical part 8, equipped with a restriction 9 defining a head 10, which forms an annular groove 11. The head 10 has a sealing surface 12 on the end part.
    The connecting element 3 has a cylindrical body 13, in the end part 14 of which a groove 15 is made, and on the side surface a groove 16. The connected pipe 2 can be moved laterally with respect to its axis and with respect to the axis of the housing 13 so that the annular groove 11 and the narrowed part 9 fit into the groove 15 and so that the head 10 fits into the groove 16.
    Inside the housing 13 there is an elongated chamber 17, which includes an axially pipe 18 and a locking means 19, driven by a liquid. The pipe 18 has the same cross section of the passage channel 20 as the channel 21 of the connected pipe 2.
    The pipe 18 is placed braidly to the wall 22 at the end of the housing 13 adjacent to the groove 16, and with respect to the inner wall 23 in the end portion 24 of the housing 13. The pipe 18 extends beyond the butt portion 24 and may be provided with an annular groove 25 defining the head part blocking 26, designed to be connected appropriately with a pipe of a fluid piping system placed in an underwater installation.
    The locking means 19 includes a clutch 27, a locking piston 28 and latches 29 located on the clutch 27. The clutch 27 carries at one end an annular mandrel 30, which is supported at the end of the clutch 27 by a corresponding stop ring 31. The mandrel 30 forms a socket 32 at one end, designed to receive a coil spring 33, the opposite end of which abuts against a socket 34, made in the protrusion 35, the piston 28 of the lock.
    The movement of the pipe 18 between the opening position (Fig. 5) and the locking and sealing position (Fig. 2), provides the input of the working fluid under pressure through the pipe 36 and the channel 37 in the end portion 24.
    The liquid is withdrawn through the channel 38 and the pipe 39.
    The connection of the pipes is as follows.
    The pressurized fluid introduced through the channel 37 moves the lockup clutch 27 to the opposite end of the housing 13 until the inclined projection 40 abuts against the corresponding protrusion 41 provided on the inner surface of the housing 13. The discharge of the pressurized fluid through the channel 38 facilitates movement the lock piston 28 to the opposite end of the housing under the influence of the difference in hydraulic pressure acting on the end of the piston 28 and the mechanical action exerted by the compressed coil spring 33. The lock piston 28 I moves to direction before sowing until the inclined protrusion 42 abuts against the corresponding inclined protrusion 43 provided on the inner surface of the lockup clutch 27 j.
    In the locked position, the tapered end portion 44 of the piston 28, to which the latches 29 are pressed in the unlocked position, moves the latches 29 axially together with the front end of the locking clutch until they stay in front of the groove 45 in the housing 13. During this / movement, the latches 29. move radially to the outside through the end face 46 of the piston 28.
    The latches 29 are mounted in the holes 47 provided in the clutch 27. In the locked position of the locking device 19, the end tapered portion of the blocked piston moves between the end portions 48 of the clutch so that the clutch 27 and the piston 28 install and maintain the latches in a locked condition. in grooves 45.
    The interlock piston is equipped with corresponding sealing joints 49 and 50, which slide in tight contact with the inner surface of the couplings U 27 and with the outer surface of the pipe 18.
    The movement of the pipe 18 during the locking operation is provided by an annular mandrel 51 with a slot, which is placed in a groove 52 made ( in the pipe 18, which is fastened with a corresponding ring 53, supported in position on the ring with a slot by the corresponding screws 54. In the locked position, the disk of a disk spring It maintained in compression inter-; dy annular holder 51 and the terminal: side lockup clutch 27. Therefore, when the latches 29 are located in grooves 45 (Figure 2) disc 55 disc spring pushes tube 18 to the connecting pipe 2. the end 56 of the pipe 18 is provided with a sealing surface 57 that extends to the outside and is intended to enter into impermeable contact with a gasket 58 formed of an appropriate compressible material and located at the end 56, while it is supported by an annular mandrel 59 inserted into the groove, provided in the sealing surface 57, expanding upward, 'Therefore, when the pipe 18 is axially moved to seal the surface 12 of the connected pipe 2, the gasket 58 is compressed between these relative surfaces 57 and 12 and forms a sealed connection.
    After the fluid under pressure drives the connecting element to bring it into the locked position (figure 2), the disk spring 55 of the disk spring. It creates a traction force on the pipe to maintain sealing contact regardless of the fluid pressure. In other words, * as soon as the connecting element is in the locked position when the fluid is under pressure, it is no longer necessary to resort to the help of this fluid to maintain the locked position and the locks are supported in the corresponding pressure grooves by the spring.
    Means are also provided for mechanically locking the pipe 18 under the condition of being liquid tight with respect to the pipe 2 being connected, in addition to the hydraulic pressure acting on the blocking sleeve 27 and piston 28.
    When the locking device is in the condition of locking and sealing the pipe joint, the mechanical locking means 60 are placed in the locking position of the pipe by the diver, if the water depth allows it), or by an underwater vehicle, or an underwater robot. These mechanical locking means 60 include an annular groove 61 formed in the pipe 18 in the region of the end face 24, in which a split split ring 62 is mounted. The locking ring adjustment bolts 63 are opposite in the end face 24. The ends 64 of the bolts 63 rest on the concave parts of the locking ring 62. When the bolts 63 are screwed, their ends bend the locking ring 62 so that it enters into the groove 61 of the pipe and establish a mechanical block with the pipe, which prevents the axial movement of the latter along with respect to the housing 13. Therefore, the mechanical locking means 60 maintain the ratio of the seal to liquid of the surfaces of the joints 57 and 12 with respect to the gasket 58.
    In order to be able to separate the surfaces of the joints of the pipe 18 and the pipe 2 to be connected (FIGS. 3 and 4), the mechanical locking means 60 are shown in the opening condition, the locking bolts 63 being unscrewed so as to expand the split lock ring 62, which then leaves the groove 61. The locking device 19 is actuated in the opening position by releasing the liquid under pressure from the pipe 5 36 and introducing the liquid under pressure through the pipe 39. The pressure liquid penetrating the chamber 17 acts first through ohm of the disk 55 of the Belleville spring U to the lock piston 28 to move it backward and to compress the spring 33. This movement of the lock piston 28 moves the surface of the end face 46 away from the latch 29 and moves the extreme narrowed part 44 at the bottom of this latch. In this case, the liquid under pressure continues to act on the lock piston 28 and on the lock sleeve 27, these two parts of the p, η move back until they abut against the end face 24. In this position, the latches 29 are pushed into the depths and are held between the end narrowed , part 44 and the opposite inner surface of the body - ^ - 5 sa 13.
    In the opening condition (Fig. 4), it can be seen that the disk spring 55 has expanded and that one of its ends is pressed against the protrusion provided on the pipe 18. In this case, this pipe is axially advanced or moved inward by a fluid pressure acting on the annular mandrels 51, 53 Until he reaches the position of FIG. 5, where the gasket 58 is separated from the head 10 of the connected pipe 2, which can then be lowered downwards due to its separation from the ramp 14.

A device for connecting pipes is known, which contains a connecting element into which the connected ends of the pipes are inserted by their axial movement tl3 ,. However, under certain underwater conditions, it is difficult to move the system installed on the seabed in the axial direction, because of the weight of the system, possible precipitation of the latter on the seabed, or because of the resistance to friction of the system on this bottom. In underwater stations it is difficult to install the appropriate ends of the systems for their connection with precise axial alignment; conditions of poor axial alignment may interfere with proper connection and the establishment of a sealed joint in the joint area. A device for connecting pipes is known, comprising a connecting element with a hydraulic piston locking system and sealing two connected pipes 2.

FIG. 1 shows a device for connecting pipes with a connecting element attached to a subsea station and a part of the end of a connecting element placed at the end of the piping system AND separated from the corresponding element of the subsea station, a partial, partial view; FIG. 2 - device for connection, the connecting element of which and the element are fastened; on the underwater station, in the locked and tight position, section (on an enlarged scale), fig. 3 - the locking device, a partial section (shown to be propelled towards the opening position); in fig. 4 shows the locking device in the open position, partially cut, in FIG. 5 shows a blocking device at the same time in hydraulic and mechanically open positions, a partial section; FIG. 6 shows section A-A in FIG. 2 (mechanical locking device in the locking position, and the pipe of the pipeline system for pumping fluid under pressure is abolished for greater clarity of the figure). The pipe connecting device 1 comprises a pipe 2 to be connected and a connecting element 3 mounted on the underwater station. Connected tyuba 2 is fixed at the end of the T | 1u.pipeline system, which can be placed on the seabed and extends from the subsea well to the subsea station 4, which has element 3. Only part of station 4 is shown in Figure a. guiding beams 5, which are fixed, for example, on the skeleton of the underwater station. The connecting element 3 can be supported and kept in a horizontal position by side nozzles 6, which at their ends carry connecting cylindrical sleeves 7 for the installation of guide rails 5. The connecting pipe 2 has a cylindrical part 8 provided with a taper 9 defining a head 10 which forms an annular groove 11. The head 10 has a sealing surface 12. The connecting element 3 has a cylindrical body 13, in the end part of which a groove 15 is made, and on the side surface groove 164 The pipe 2 to be connected can be moved laterally with respect to its axis and relative to the axis of the housing 13 so that the annular groove 11 and the constricted part 9 enter the groove 15 and that the head 10 enter the groove 16. Inside the housing 13 there is an elongated chamber 17, which includes an axial tube 18 and locking means 19, driven by a fluid. The pipe 18 has the same cross section of the passageway 20 as the channel 21 of the pipe 2 to be connected. The pipe 18 is located at the end of the housing 13 adjacent to the groove 16 and relative to the inner wall 23 in the front part 24 of the housing 13. The pipe 18 extends beyond the toe part 24 and may be provided with an annular groove 25 defining a locking head 26, which is designed to be connected in an appropriate manner with the pipe of the fluid piping system placed in the subsea installation. The locking means 19 includes a clutch 27, a locking piston 28 and locks 29 located on the clutch 27. The clutch 27 carries at one end an annular mandrel 30, which is supported at the end of the clutch 27 by a corresponding stop ring 31. The mandrel 30 forms a socket 32 at one end intended to receive a coil spring 33, the opposite end of which abuts against the seat 34, formed in the protrusion 35, of the lock piston 28. The movement of the pipe 18 between the opening position (Fig. 5) and the position of the blocking and sealing (Fig. 2) ensures that the working fluid is introduced under pressure through the pipe 36 and the channel 37 in the end portion 24. The liquid is discharged through the channel 38 and the pipe 39. The pipe connection is as follows. The pressurized fluid introduced through the channel 37 moves the locking sleeve 27 to the opposite end of the housing 13 until the inclined protrusion 40 rests on the corresponding protrusion 41 provided on the inner surface of the housing 13. The liquid under pressure through the channel 38 facilitates the movement of the blocking piston 28 to the opposite end of the housing under the influence of the difference in hydraulic pressure acting on the end of the piston 28 and the mechanical action exerted by the coil spring 33. The locking piston 28 moves in until the inclined protrusion 42 rests on the corresponding inclined protrusion 43 provided on the inner surface of the locking collar 27. In the locking position, the end conical 44 portion of the piston 28, against which the latches 29 are pressed in the open position, moves simultaneously with the front end the locking clutch locks 29.axially until they stop opposite the groove 45 in the housing 13. During this / movement locks 29. move radially to the outer side through the end 46 of the piston 28. The fixtures 29 are mounted in the holes 47 provided in the coupling 27. In the locking position of the locking device 19, the end of the narrowed part of the blocked piston moves between the end parts 48 of the coupling so that the coupling 27 and the piston 28 install and maintain the locks in the locking condition in the slots 45. The locking piston is provided with corresponding sealing joints 49 and 50, which slide in tight contact-G with the inner surface of the muffle 27 and with the outer surface pipe 18. The movement of the pipe 18 during the locking operation is provided by an annular mandrel 51 with a slot, which is placed in a groove 52, made in the pipe 18, which is attached with a corresponding ring 53, supported in position on the ring with a slot with corresponding screws 54. In the locked position the disc spring is kept in compression between the annular mandrel 51 and the end side of the locking collar 27. Therefore, when the latches 29 are located in the grooves 45 (FIG. 2) the disc 55 of the disc spring pushes the pipe 18 to Tube 2. The end 56 of tube 18 is provided with a sealing surface 57 extending to the outside to fit into an impermeable contact with a gasket 58 formed from a corresponding compressible material and located at the end 56, while it is supported by an annular mandrel 59 inserted into a groove provided in the sealing surface 57 extending upward. Consequently, when the pipe 18 is axially moved to seal the contact to the surface 12 of the connecting pipe 2, the gasket 58 is compressed between these sealing surfaces 57 and 12 and forms a tight joint. After the pressurized fluid actuates the connecting member to bring it to the blocking position (Fig. 2), the disk spring disk 55 creates a thrust force on the pipe to maintain the sealing contact regardless of the fluid pressure. In other words, as soon as the connecting element is in the locked position when exposed to a liquid under pressure, it is no longer necessary to resort to using this liquid to maintain the locked position and the locks are supported in the corresponding grooves under the pressure of the springs. Means are also provided for mechanically blocking pipe 18 in a fluid tight condition with respect to the pipe 2 to be connected, additionally to the hydra, the influence pressure acting on the locking sleeve 27 and the piston 28. When the locking device is in the condition of blocking and sealing the pipe joint The mechanical blocking means 60 is placed in the stop position of the pipe by the diver, if the water depth allows for it, or by an underwater vehicle, or driven by a robot. These mechanical blocking means 60 include an annular groove 61 formed in the pipe 18 in the area of the end face 24, in which the interlocking split ring 62 is installed. The locking bolts 63 of the lock ring are located diametrically opposite at the end face 24. The ends 64 of the bolts 63 rest on the concave portions of the locking ring 62. When the bolts 63 are screwed,. their ends cause the locking ring 62 to bend in order to insert it into the groove 61 of the pipe, and install a mechanical interlock with the pipe, which prevents the axial movement of the latter relative to the housing 13. Therefore, the mechanical interlocking means 60 maintains the seal-to-liquid ratio connections 57 and 12 with respect to the gasket 58. In order to be able to separate the surfaces of the connections of the pipe 18 and the pipe 2 to be connected (Figs. 3 and 4), the mechanical blocking device 60 is shown in the opening condition, and The locking bolts 63 are unscrewed to ensure the expansion of the split locking ring 62, which then exits the groove 61, the locking device 19 is brought into the unlocking position by discharging the pressurized fluid from the pipe 36 and injecting the pressurized fluid through the tube 39. The fluid under pressure, penetrating into chamber 17, first acts through the disc spring disk 55 on the lock piston 28 to move it back and to compress the spring 33. This movement of the lock piston 28 pushes the surface of the end face 46 by moving the retainer 29 and a tapered portion 44 of the extreme bottom of the retainer. When this fluid under pressure continues to act on the piston 28 of the lock and the locking sleeve 27, these. the two parts move backward until they are pressed into the end 24, In this position the latches 29 move back inwards and are held between the end of the narrowed, part 44 and the opposite inner surface of the housing 13. In the opening condition (Fig.4) you can see that the disk 55 of the disc spring pa: c 1111rils and that one of its ends was pressed against the protrusion, provided for HHOf y on the pipe 18. In this case, the pipe is axially advanced or shifted inward by the fluid pressure acting on the ring mandrels 51, 53 yo, until he reaches the position of FIG. 5, where the gasket 58 is separated from the head 10 of the pipe 2 to be connected, which can then be lowered down due to its separation from the skokoy 14.
