WebNov 6, 2024 · When two superheated pieces of pipe are pushed together, or a welding rod is applied, a bead of material may form around the inside of a pipe. This bead can restrict water flow, and create eddies, where microorganisms like to grow. With solvent cement, after basic instruction anyone can join CPVC pipe and fittings. WebMar 14, 2024 · Hot air welding is a joining method that uses high heat to make chlorinated polyvinyl chloride (CPVC) material reach its melt state. Pushed together for a certain amount of time at a specific pressure, this method allows the surface molecules of the two pieces to interlock, fusing them together.
WebJun 24, 2024 · PVC (polyvinyl chloride) pipes and fittings can withstand a variety of environments for 100 years or more, according to the Plastic Pipe and Fittings Association. In most cases these strong materials outlast the structures they’re used in. PVC pipes and fittings are welded with PVC cement solvent. WebThe pipes rest on the hot plate which allows the heat to permeate the material, reducing the possibility of cold welds. This time will vary subject to pipe diameter and wall thickness, therefore manufacturers …
