A pipe fitting () includes a tubular connecting part (); the tubular connecting part being configured to be inserted into an expanded pipe end section () of a pipe () having a first circumferential intact sealing region () on the inner surface () of the pipe end section (); the tubular connecting part comprising a first radially outwards extending circumferential sealing barb (') positioned for engaging, when in use, with the first circumferential intact sealing region during shrinkage of the pipe end section for forming a sealing between the pipe fitting and the pipe.

Cold expansion pipe fitting, pipe connection, system, equipment, and method

A valve comprises a housing and at least three ceramic discs in the housing such that at least two fixed ceramic discs are provided and at least one rotatable ceramic disc is provided between the fixed ceramic discs. The ceramic discs comprise through holes such that when the holes are aligned, the valve is open, and turning the rotatable ceramic disc turns the holes to be misaligned in successive ceramic discs, which prevents water flow through the valve. The valve further comprises a handle for rotating a rotatable ceramic disc and the handle comprises a stem extending through the housing, and a curved part, the curved part curving at least partly around the housing along the circumference of the housing.
