New Focus on CPVC Best Practices - Manufacturers are working to improve CPVC installation education

摘要

The use of nonmetallic pipe in fire sprinkler systems is fairly modern, but there have been several distinct eras involving different types of products. As manufacturers of some types of nonmetallic piping seek broader acceptance, others are working to ensure the use of best practices for installation and use. The first nonmetallic material listed for use in fire sprinkler system pipes was polybutylene, a flexible piping product joined by a heat fusion technique that came onto the scene in 1983. It showed great promise, but within a decade, failures in plumbing systems led to a class action lawsuit and the end of polybutylene fire sprinkler piping.
