    The invention relates to devices for controlling threading devices connected to:, Research Institute of couplings with pipes for tightness.
    The purpose of the invention is to increase reliability by eliminating the effect on the joint of the spacer forces created by the working fluid loading this compound.
    The drawing shows a device for testing threaded connections of couplings with oil field pipes, a general view.
    The device contains a working fluid supply system (not shown in the drawing) to the monitored threaded joint in the form of a sleeve 1, which surrounds the pipe 2. The guide columns (not shown) are axially mounted with a height adjustable clamping head, made in the form of an outer sleeve 3 with a V-sealing sealing element 4 attached to one of its ends to enclose the outer surface of the coupling 1. One of the ends of the internal sleeve 5 is attached to the other end of the outer sleeve 3 with V-shaped a sealing member 6 for sealing the inner surface of the tube 12. The sleeve 5 is placed in the sleeve 3 to form a gap 7 for receiving. Couplings 1 with pipe 2. The nipple 7 from the side of the fastened ends of the sleeves 3 and 5 placed thrust ring 8. The padding pad 9 is designed to interact with the sleeve 2 covering the pipe 2 with the sleeve 10 connected to the working fluid supply system .
    A device for monitoring threaded connections of couplings with pipes for oil fields works as follows.
    Place the clamping head at a height corresponding to the size of the pipe 2. Insert the pipe, 2 with coupling 1 into gap 7 until the coupling 1 stops into the stop ring 8. Feed the gland 9 to the end of coupling 1, clamping it. Through the cylinder 10 into the gap 7,: formed by the 1st sleeve 3 and 5, the working fluid is supplied, for example oil, which penetrates
    to the V-shaped sealing element A and 6, it deforms them and seals the outer surface of the coupling 1 and the inner surface of the pipe 2. The air filling the gap 7, at the same time, is released. As soon as the oil from the gap 7 goes without air bubbles, it stops draining and serves little to a predetermined pressure in the gap 7. Block fitting 10 and maintain the connection under this pressure for a specified time.
    At the same time, the gland block 9 prevents the thrust force generated by the oil on the ends of the coupling 1 and the pipe 2.
    The tightness of the joint is monitored and the oil is drained from the gap 7.

    Invention Formula
    A device for monitoring the tightness of threaded connections of couplings with oil field pipes, containing a system for supplying working fluid to a controlled connection, guiding columns and a clamping head mounted on them with the possibility of movement, made in the form of a sleeve and attached to one of its ends a sealing element intended to hermetically cover the outer surface of the coupling, characterized in that, in order to increase reliability, it is provided with a movable preload pad, designed to interact with the female end of the coupling, the inner sleeve installed in the outer sleeve with a gap between their surface M and M to accommodate the controlled connection and attached one of its ends to the other end of the outer sleeve, an additional V-shaped sealing element attached to another end of the inner sleeve and intended for sealing the inner surface of the pipe, and a stop ring placed in the gap on the side of the bonded ends of the sleeves.
