HDPE Union
An HDPE Union is a highly practical and versatile pipe fitting manufactured from high-density polyethylene (PE100/PE80 grades), specifically designed to connect two sections of HDPE pipe in a manner that allows for easy assembly, disassembly, and reusability without compromising the integrity of the pipeline. Unlike permanent fusion joints, the union fitting enables pipelines to be conveniently disconnected for maintenance, repair, inspection, or extension, making it an essential component in dynamic piping systems. It provides a strong, leak-proof connection while maintaining the benefits of HDPE such as lightweight design, excellent corrosion and chemical resistance, flexibility, impact strength, and long service life.
HDPE unions can be joined using threaded, compression, or mechanical methods, making them especially useful in applications where quick installation or frequent disconnection is required. Owing to their durability and reliability, HDPE Unions are widely applied in sewage and wastewater management, gas pipelines, and industrial fluid handling systems, offering a service life of 50+ years under normal operating conditions.
