An electrofusion coupling () for joining together two or more sections of pipe, said coupling comprising: (i) a substantially cylindrical coupling body having an outer surface and an inner surface, the inner surface being sized and shaped to form a clearance fit with the outer surface of the pipe regions to be joined; (ii) at least one electrical heating () element set on or in the inner surface of the coupling body; (iii) terminal means adapted to connect the electrical heating means to an electrical supply; characterized in that the terminal means does not project beyond the outer cylindrical surface of the coupling body once the welding process is complete.

Welding socket

A rotary slide for medium-carrying pipelines is proposed, comprising a housing () capable of being installed between two pipeline ends and having a stop member () for shutting off the pipeline and having an actuating device () for actuating the stop member, the housing possessing a first reception region () for receiving the stop member in the closed position of the rotary slide, a second reception region () for receiving the stop member in the open position of the rotary slide and a drive region () for receiving the actuating device, and the drive region () being arranged in the housing () separately from the first and the second reception region (). The rotary slide is distinguished by a compact and corrosion-resistant form of construction.
