    Abstract: A pipe coupling includes a rigid cylindrical member, a flexible cylindrical member and a hose clamp. The flexible cylindrical member includes a central tubular member within the rigid cylindrical member. A flexible sleeve extends beyond the rigid cylindrical member and has an inside diameter that is complimentary to a pipe. The sleeve has a first position in which the sleeve is folded back onto the rigid cylindrical member and a second position in which the sleeve is unfolded so as to envelope an end of the first pipe. The central tubular member includes a ledge that has an inside diameter corresponding to an inside diameter of the pipe.

    Abstract: The present invention concerns a rotatable coupling (60) for connecting pipes, comprising a first hollow female element (61) suited to be connected, for example, to a first pipe portion (51), and a second tubular male element (6) with a first end portion at least partially housed inside the first female element (61) so as to define an inner space for the passage of a fluid, and with a second end portion suited to be connected to a second pipe portion (52). Said first and said second element (61, 6) can be rotated with respect to each other, said second tubular male element (6) comprising a first abutment surface (6S). Furthermore, the rotatable coupling (60) comprises a third hollow tubular element (12) housed inside the first female element and provided with a second abutment surface (1S) substantially opposite the first abutment surface (6S) so as to define a first interspace (I), and the third tubular hollow element (12) can be translated along a direction substantially orthogonal to the first and the second abutment surface (6S, 1S) between a closed configuration, in which the first and the second abutment surface (6S, 1S) are positioned at a minimal mutual distance, and an open configuration, in which the first and the second abutment surface (6S, 1S) are positioned at a distance that exceeds said minimal mutual distance.

    Abstract: A venting system includes a vent for expelling gases that accumulate between a metal pipe and a plastic liner disposed within the metal pipe. The vent includes a base portion that is configured to be disposed between the plastic liner and a wall of the metal pipe. The base portion has at least one channel extending along the base portion to a central region of the base portion. The vent includes an exhaust portion that protrudes from the central region of the base portion and is adapted to extend through the wall of the metal pipe. The exhaust portion has a central passage that interconnects with the at least one channel of the base portion, such that the vent is configured to vent gases from an interface area between the plastic liner and the wall of the metal pipe to an exterior atmosphere outside the metal pipe.
