This document discusses HDPE pipe fittings and joining methods. It explains that HDPE is a strong, corrosion-resistant plastic used for pipes and other applications. There are two main methods for joining HDPE pipes - electrofusion and butt fusion. Electrofusion uses an electrically heated plate to melt the pipe ends together, while butt fusion uses heat from an external source to melt and fuse the abutted pipe ends. The document also briefly describes a miter box for making accurate cuts at various angles for joining pipes and molding.

2. HDPE Pipe
• High-density
polyethylene (HDPE) or
polyethylene high-density
(PEHD) is a thermoplastic
polymer produced from the
monomer ethylene. With a high
strength-to-density
ratio, HDPE is used in the
production of plastic bottles,
corrosion-resistant piping,
geomembranes and plastic
lumber.
