What To Know When Working With CPVC Pipe Fittings And Pipe

CPVC or chlorinated polyvinyl chloride is made through chlorination of standard PVC or polyvinyl chloride resin. This is a thermoplastic, and the chlorination process, or the addition of a free radical chlorination reaction, occurs when the pipe is exposed to thermal or UV energy.

This reaction replaces the hydrogen in the molecular structure of the pipe to be replaced with chlorine. The resulting change, which can include up to 69% chlorine replacement of the hydrogen in the pipe. At the same time, additional chemicals, such as stabilizers, lubricants, and pigment is also added to the resin to result in a highly workable, corrosion and heat resistant pipe.

Benefits of CPVC

Working with CPVC pipe fittings and pipe is easier than working with the older and basic PVC pipe. This is a material that is ideally suited to any type of process where heat is involved, including welding processes and machining. This is also an ideal material for bending and shaping, and it can be used to replace metal pipes as it has a comparable strength with regards to crushing concerns.

CPVC pipe is resistant to fire, so it can be used in fire suppression systems. It is also rated for use at up to 100 psi at temperatures up to 180 degrees, making it a good option for many applications. It is the piping option in areas where aggressive water is a problem with corrosion with other types of pipes.

Basic Tips

By using CPVC pipe fittings and CPVC pipe, the ability to quickly install fittings in the line is a given. Specialized solvent cement can be used to fix the fitting in place and keep them permanently fixed without the need for additional exterior types of clamps or supports.

As this is a lightweight pipe, the CPVC pipe fittings can be installed in any location, including on long runs of pipe. Simple supports or hangers can be used as needed to hold the weight of the pipe on these longer runs.
