    improved against flat or conical interfaces.
    As shown in Figures 11 and 12, exemplary ribs 50 and 60 are marked with various dimensions. Such dimensions A, B, H and W can be varied to suit a given application. In addition, as described above, the spacing of the ribs can be varied to produce optimal sealing conditions. By varying the width W of the sealing face, a flat peak or a sharp peak can be obtained. With reference to Figure 12, the size of the radius R can be varied, or the radius can be removed to be non-radial.
    The second and third embodiments of an adapter incorporating a seal are illustrated in Figures 13A-13B and 15A-15B, respectively. Figure 14 illustrates a length of a corrugated pipe, preferably stainless steel corrugated pipe with a rib sealing region 111 identified by the dashed line in Figure 14. The pipe shown in Figure 14 has a sealing region of generally circular ribs configured for use in the second or third embodiments described herein or other embodiments of the present invention. The similar elements that appear in the second and third embodiments of Figures 13A-13B and 15A-15B, which have structures and / or functions similar to the elements of the first embodiment are preceded by a "1" or a "2" to designate similar structures.
    With reference to the second embodiment of Figures 13A-13B, an adapter 120 is connected to a length of pipe 110, where the pipe 110 is optionally jacketed, and a jacket 114 can be detached to expose at least one corrugation of the pipe, for example at least one extreme undulation 110a. The extreme corrugation 110a is also illustrated in Figure 14, where a dashed line designates the rib sealing region 111 of the pipe 110. In particular, after sealing the extreme corrugation 110a according to the second and / or third embodiments of the present invention, the extreme undulation 110a will be crushed
    or it will compress along the rib sealing region 111, thereby producing a generally circular profile after crushing and / or compressing the extreme undulation 110a.
    Referring again to Figures 13A-13B, the components of the adapter 120 are generally the same as those illustrated in the first embodiment of Figures 3 and 4. The adapter 120 includes a main body (or adapter) 122 which it has a hole to receive the pipe 110. The adapter 120 also includes a nut 124 and a split bushing 126 received in the main body 122 of the adapter. As shown in Figure 13A, the split bush 126 includes at least two internal ribs 128a and 128b spaced apart for engagement with circumferential grooves of the pipe 110. The internal ribs 128a and 128b can be coupled and alienated the pipe 110 and / or the jacket 114 inside the split sleeve 126, thereby centering the pipe 110 inside the adapter 120, such that at least one undulation of the pipe 110 is received between the sealing surfaces of the main body 122 and the split sleeve. The internal ribs 128a and 128b also provide a strain relief where the outer diameter of the corrugated pipe is coupled with the split bushing
    126. In addition, the split bushing 126 may include one or more additional contact points 127 with the pipe 110 and / or the jacket 114 to align the pipe 110 within the adapter 120 and relieve tension. In other words, the split bushing includes several contact points or regions to contact at least one of the pipe and jacket, which can provide alignment and strain relief functions.
    At least the main body 122 and the split sleeve 126 are formed with sealing surfaces, where the main body 122 has a stop projection 132 defining a first sealing surface. In FIGS. 13A13B, the stop projection 132 is formed with a plurality of ribs; alternatively, the first sealing surface can be flat.
    The structure and function of the previous components of the adapter 120 are generally the same as those described with reference to the first embodiment. However, in the second embodiment of Figs. 13A-13B, the main body 122 has an inner wall 122a sized to produce a generally circular shape or profile of the extreme corrugation 110a of the pipe when it is crushed between the first and the Second sealing surfaces. In other words, an inner diameter of the main body 122 is sized to maintain a generally circular shape of the crushed end corrugation 110a, where the end corrugation 110a can contact the inner wall 122a during sealing. By virtue of this contact between the end corrugation 110a and the inner wall 122a, the end corrugation 110a is properly aligned and centered on the pipe 110, thereby producing a generally circular sealing profile of the end corrugation 110a.
    As shown in Fig. 13B, the inner wall 122a of the main body 122 restricts the outward movement of the end ripple 110a when the end ripple 110a is received between the first and second sealing surfaces. In other words, the interface between the inner wall 122a and the extreme undulation 110a restricts an outer diameter of the extreme undulation 110a, such that an inner diameter of the main body 122 (i.e., the inner wall 122a) and the extreme undulation 110a essentially form an interference fit. As a result, the crushed end ripple has a generally circular shape, and remains substantially concentric with the rest of the length of the pipe.

    Referring to Figures 15A-15B, the components of the adapter 210 include a main body (or adapter) 222 having a bore to receive a length of pipe 210. The adapter 220 also includes a nut 224 and a split bushing 226 received in the main body 222 of the adapter. In the third embodiment of Figures 15A-15B, the adapter 220 is formed with normal ribs 228a and 228b that can be coupled and aligned with the pipe 210 and / or the jacket 214 inside the split sleeve 226, such that at less an extreme undulation of the pipe 210 is received between the sealing surfaces of the main body 222 and the split sleeve 226. The internal ribs 228a and 228b also provide strain relief, where the outer diameter of the corrugated pipe is coupled with the split sleeve 226. In addition, the split sleeve 226 includes one or more additional contact points 227 with the pipe 210 and / or the sleeve 214 for alignment of the pipe inside the adapter and relieve tension. In other words, the split sleeve 226 includes several contact points or regions to contact at least one of the tube 210 and the sleeve 214, which can provide alignment and strain relief functions.
    At least the main body 222 and the split sleeve 226 are formed with sealing surfaces, where the main body 222 has a stop projection 232 defining a first sealing surface (see Figure 15B). In the third embodiment, the shoulder boss 232 is formed with a plurality of ribs; alternatively, the first sealing surface may be smooth.
    The structure and function of the previous components of the adapter 220 are generally the same as those described with reference to the first embodiment. However, in the third embodiment of Figs. 15A-15B, the bushing 226 has an inner wall 226a sized to produce a generally circular shape or profile of the extreme corrugation 210a of the pipe when it is crushed between the first and second sealing surfaces. In other words, an inner diameter of the sleeve 226 is sized to maintain a generally circular shape of the crushed end corrugation 210a, where the end corrugation 210a can contact the inner wall 226a during sealing. Under this context between the extreme undulation 210a and the inner wall 226a, the extreme undulation 210a is properly aligned and centered on the pipe 210, thereby producing a generally circular sealing profile of the extreme undulation 210a. The inner wall 226a can also serve as a sealing surface, such that the extreme corrugation 210a of the pipe is sealed against the inner wall 226a in a cone of about 0 to 10 degrees, preferably about 5 degrees.
    As shown in Fig. 15B, the inner wall 226a of the bushing 226 restricts the outward movement of the end ripple 210a when the end ripple 210a is received between the first and second sealing surfaces. In other words, the interface between the inner wall 226a and the extreme undulation 210a restricts an outer diameter of the extreme undulation 210a, such that an inner diameter of the socket 226 (i.e., the inner wall 226a) and the extreme undulation 210a they essentially form an interference fit. As a result, the crushed extreme undulation has a generally circular shape, and remains essentially concentric with the rest of the length of the pipe.
    According to the second and third embodiments described in FIGS. 13A-13B and 15A-15B, respectively, a crushed diameter of the extreme undulation 110a or 210a can be controlled to produce a substantially circular profile or shape, when compared with an oval shape, which can result from the crushing and sealing of the extreme undulation 10a in the first embodiment of figures 3 to 4. Although an oval shape of the crushed extreme undulation produces a suitable sealing profile in certain applications, in others Applications It is desirable to produce a sealing profile that approximates the shape of the remaining corrugated pipe. Such a profile or circular shape also ensures that adequate contact is made between the first and second sealing surfaces and the at least one crushed undulation. In addition, where the first and / or second sealing surfaces are provided with ribs, a circular profile can ensure adequate contact between the rib surfaces and the crushed pipe. In other words, by controlling an outer diameter of the crushed pipe, the pipe can be properly aligned on the ribs (concentrically), thereby producing a more reliable seal. The control of the outer diameter of one or more crushed undulations is achieved by allowing the pipe to contact an inner wall of the main body of the adapter and / or the bushing, as provided in the second and third embodiments.
    In accordance with the present invention, the term "extreme undulation" comprises one or more undulations of the pipe, for example about 1 to 3 more extreme undulations, such that one or more undulations can be crushed and sealed by the sealing device. .
    The ribbed sealing surface described herein can be formed in several profiles, as described above. For example, a configured cross section can be used, where the ribs can have one or more of the following shapes: conical, toroidal, elliptical, parabolic and grooved. In addition, an interface between the bushing and the main body can be straight or conical, where a cone can be varied to suit a specific application. A suitable conical bushing can have a conical shape, a barrel shape, or other configuration.

    The sealing has been described with reference to different forms and examples of embodiment of sealing ribs, in which the number and / or type of ribbing is varied. It is within the scope of the present invention to provide a sealing device that includes ribs having characteristics of more than one of the described embodiments.
    5 As another alternative, in a second and third embodiments, it is possible to form the first and second sealing surfaces without ribs. In such embodiments, the sealing can be adequately controlled by controlling the outside diameter of one or more crushed undulations, thereby producing a generally circular sealing profile.
    A method of sealing a length of pipe to an adapter according to the present invention may include the
    10 stages of: providing a main body having a first sealing surface; providing a bushing received in the main body, the bushing having a second sealing surface configured to engage the first sealing surface with at least one undulation of the received pipe between the first and second sealing surfaces; forming a plurality of ribs on at least one of the first and second sealing surfaces; and crush the at least one ripple between the first and second sealing surfaces, in such a way
    15 that the ribs contact the at least one undulation to form a seal, in which at least one of the bushing and the main body is sized to maintain a generally circular shape of the at least one undulation.
    The present invention also comprises methods for transporting gas and liquid through a tube or pipe, in which at least one length of pipe is sealed to an adapter as previously provided. The method
    20 may include transporting the gas and liquid to a device, such as a boiler, oven or stove.
    The present invention further comprises a method for installing a pipe or pipe system in a structure, such as a commercial or residential building, where the installation method includes installing at least one pipe or pipe length that is sealed to an adapter. as previously provided. For example, the tube system
    or pipe can use CSST pipes or pipes.
