In polyethylene piping systems for conveying pressurised water the use of socket systems for pipe joining is relatively uncommon. This is because the significant thickness of the pipe walls makes the system for thermoforming of the socket at the pipe end complex and economically unattractive. Only recently developments in the field of high-density polyethylene using formulae offering superior physical and mechanical properties, such as bimodal PE100, have made it possible to produce thinner walled pipes. Consequently, SICA has developed a process designed for thermoforming of complete sockets on PE100 pipes. This document describes the socket forming process that SICA has implemented in an automatic machine destined to function in an extrusion line, and the benefits offered by the use of this new technology.
