Abstract: A pipe repair clamp which allows a locking plate to slide over a plurality of lugs into position making it easier to close the clamp around a pipe. The pipe repair clamp includes a flexible strap formed into a substantially cylindrical body defining a hollow bore. The strap has a first and second ends which are brought together when the clamp is closed. A thrust plate is secured near the first end of the flexible strap. At least one lug is secured to the thrust plate and extends perpendicular to the thrust plate. The lug plate is secured near the second end of said strap. At least one threaded stud is secured to the lug plate and is used to tighten the clamp closed. A lug cover plate is perpendicularly secured to the lug and the thrust plate and has at least one opening to receive the threaded stud. The lug cover plate also includes a curved end portion covering at least a portion of the lug. A locking plate has at least one opening and is adapted to receive the threaded stud.

Abstract: A pipe joint, and a method of forming a pipe joint between two metallic pipes which have been internally and/or externally coated with a material to prevent corrosion includes a spigot and a socket. The socket has, or is formed with, an internal circumferential groove (6) that provides a seating for an elastomeric sealing ring (8). An extension or lip (13) forward from the groove provides a welding location (14) remote from the sealing ring. The coating on the end of the socket if necessary is removed to facilitate welding. The spigot has a heat sink member (9) to enable the lip of the socket to be welded to the metal of the spigot.

Abstract: A method for providing protection against corrosion of a pipe joint (1) formed by the mating of complementary ends (4, 5) of two pipes comprising the steps of:(a) applying controlled heating to a pipe body which is to be joined to an adjacent pipe,(b) applying to the ends (4, 5) of each pipe a protective layer or coating of material 2 to the pipe body by a time/temperature function process,(c) allowing the pipe to cool,(d) bevelling the terminations of the protective layer or coating (2),(e) mating complimentary ends (4, 5) of the pipes together to form a sealed and corrosion resistant joint (1).
