HDPE Backing Ring Flange
A HDPE Backing Ring is a pipe fitting made of high-density polyethylene (HDPE) used to provide support and reinforcement to HDPE flanges, especially during bolting and connection to other piping components. It ensures a tight, leak-proof joint by distributing the load evenly across the flange and preventing deformation of the HDPE material. HDPE backing rings are lightweight, corrosion-resistant, durable, and commonly used in sewage, and industrial piping systems. They are typically used in combination with HDPE flanges for secure and long-lasting pipeline connections.
