Cold welding, using adhesive, or a simple adhesive joint, a special longitudinal connection that is used to connect pipes and fittings from PVC or CPVC.
Adhesive joint is performed using the appropriate adhesives / adhesives derived from the decomposition of polymers PVC or CPVC in a mixture of solvents, which soften the walls of pipes and fittings before subsequent coupling. Chemical welding can obtain permanent connection with the chemical and mechanical strength, comparable with similar characteristics used pipes and fittings. Adhesives and adhesive should be selected taking into account the type of thermoplastic compounds, subjected to welding, because the properties of solvents and additives can be changed.
