A fitting designed to connect high-density polyethylene (HDPE) pipes to flanged systems or components incorporates a flange adapter. This adapter typically consists of an HDPE body molded to accept a backing ring, usually made of metal. The backing ring provides structural support and allows for secure bolting to a mating flange. This connection method allows for easy assembly and disassembly of piping systems.
This connection method is crucial for applications requiring corrosion resistance and flexibility inherent in HDPE. Its use streamlines installation, reduces maintenance costs, and ensures long-term performance in diverse environments. Historically, this type of adapter provided a reliable alternative to direct welding of HDPE to metallic flanges, addressing concerns about material compatibility and joint integrity.
