HDPE Fusion Procedures

HDPE Fusion Procedures August, 2010 Roth 2 Allowable Piping Materials High-density polyethylene pipe (HDPE) and cross-linked polyethylene pipe (PEX) are the only two types of piping material suitable for use in buried ground loop systems. When burying HDPE or PEX pipe, mechanical fittings are not allowed with the exception

HDPE pipe - Wikipedia

HDPE pipe is a type of flexible plastic pipe used for fluid and gas transfer and is often used to replace ageing concrete or steel mains pipelines. Made from the thermoplastic HDPE (high-density polyethylene ), its high level of impermeability and strong molecular bond make it suitable for high pressure pipelines.

Heat fusion - Wikipedia

Heat fusion (sometimes called heat welding, butt welding or simply fusion) is a welding process used to join two different pieces of a thermoplastic.This process involves heating both pieces simultaneously and pressing them together. The two pieces then cool together and form a permanent bond.

How To Make Proper HDPE Electrofusion Joints

Heat fusion can be used to join sections of HDPE pipe, including high-performing PE4710 pipe, while electrofusion is used to add couplings, tapping tees, branch saddles and other fittings. Proven to be a reliable joining system, an electrofusion joint is heated internally, either by a conductor at the interface of the joint or by a conductive polymer. Heat is created as an electric current is applied to the conductive …
