The invention relates to a plug connection between two tubular workpieces (1, 2) which are made of concrete and each of which has an inner liner (5) made of plastic, one of which forms a tip end (3) and the other a socket end (4) receiving the tip end (3), wherein the inner liners (5) have circumferential sealing flanges (12) which cover the end face (13) of the tip end (3) or the socket face (14) and wherein a joint seal (16) is provided between the sealing flanges (12). In order to provide advantageous structural conditions, it is proposed that the inner liners (5) are provided with a circumferential elastomer angled profiled section (8, 9) at the end face, which receives the circumferential edge of the inner liner (5) in an end-face profiled groove (11) of its axially parallel limb (10) and whose limb at a right angle to the axis forms the sealing flange (12).

A system and method for coupling sections of pipe is disclosed, wherein the system preferably comprises a frame, a carriage and a controller. In embodiments, the frame comprises a pipe frame, which preferably extends substantially the entire length of the system and may be secured via a chain. The system in a preferred embodiment may be secured to a piece of machinery, such as an excavator bucket, back hoe or equivalent machinery for moving a first section of pipe to a location where a second section of pipe resides for coupling the first and second sections of pipe. Methods of use are also disclosed herein.

A tubing clamp and method using an inner ring providing shape support to a layflat tubing to provide a compression surface against which an outer split ring with segmented pressure fingers can be compressed using an overcenter clamp to secure a back folded first end of a piece of tubing to a second overlaid tubing end.

An aseptic coupling device for a tube, the device comprising: a tubular insert defining a channel and having an end segment provided with means for connecting it to the tube, the tubular insert being provided with a cantilevered rod extending axially inside the channel; and an annular body having an end segment mounted on the insert and co-operating therewith to define a housing for receiving an annular sealing element that is deformable from a first state in which it defines a flow section greater than the cross section of the rod and a second state in which it tightly surrounds the rod, and that is arranged to be taken from its first state to its second state under the effect of axial compression exerted by the insert.

A coupling assembly for coupling two tubes together.

Electrofusion tape and method for the production thereof for welding together with plastics pipes in particular for use in a fixed-point fastening, consisting of a jacket element preferably of an electrically insulating plastics material, at least one heating element of electrically conductive plastics material and at least two contact elements for supplying electricity to the heating element, wherein the jacket element and the heating element take the form of tapes, wherein the jacket element surrounds the heating element at least in part, wherein the contact elements are arranged in the mutually opposing marginal regions of the heating element and extend parallel to one another along the heating element.
