Chemical systems must be drained and vented through what type of piping?

Chemical systems require drainage and venting through approved material piping to ensure safety and compliance with regulations. Using approved materials means that the piping has been certified for the specific chemical substances it will be handling, minimizing risks such as leaks, corrosion, or reactions that could occur with incompatible materials. This is critical in protecting both personnel and the environment.

Approved material piping typically includes options like PVC, CPVC, or other materials designed to withstand the chemical's properties, including temperature and pressure. By adhering to regulations that mandate the use of approved materials, the integrity of the piping system is maintained, and the risk of hazardous situations is significantly reduced.

Other materials, such as plastic only, metal only, or flexible piping alone may not meet all the comprehensive safety and compatibility standards required for certain chemical applications, which is why they do not serve as a universal solution for all chemical drainage and venting needs.
