Of course, there are many restrictions on the use of any material for transport of alkalis or acids. Restrictions imposed by the manufacturing processes. For example, the PVC is resistant to caustic soda and potassium hydroxide to no, while the PP (PP-H100) resistant to both agents.
In this regard, we ask you in each case refer to our program on the selection of materials, compiled on the basis of a table of chemical resistance of polymeric materials.
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.
