Description of High Density Polyethylene (HDPE) pipe and fitting.
HDPE pipe, also known as high density polyethylene or polyethylene pipe, is made of HDPE granular material and is a flexible plastic pipe used for fluid and gas transportation.
High Density Polyethylene (HDPE) pipes are the ideal pipe material choice for applications like drinking water, wastewater, mining, industrial systems, power, communications, irrigation, fire protection, marine aquaculture, dredging works, oil and gas distribution.
HDPE pipe has features of abrasion resistance, chemical resistance, toughness, leak-free welded joints, etc. It can transport and distribute water and gas. The long life and low maintenance cost of HDPE pipe, combined with its ability to use a variety of trenchless installation techniques, gives HDPE pipe the lowest life cycle cost.
Tianmai pipeline is the ideal piping solution with the safty and reasonable price.
Jointing methods that fit HDPE pipe:
Butt fusion welding, Socket fusion welding, Flange connection, Electrofusion welding, Saddle welding, Quick fittings connection
1. HDPE pipe butt fusion connection: Butt fusion is to use a butt fusion machine to heat the end of the pipe. After the end of the pipe is melted, it is quickly attached, maintaining a certain pressure, and then cooling to achieve the purpose of welding. HDPE pipes with a size larger than 90mm can be connected by the butt fusion process. This method is economical and reliable, and the tension and pressure of the joint have higher strength than the pipe itself.
2. HDPE pipe socket fusion connection: It heats the outer surface of the HDPE pipe and the inner surface of the HDPE pipe fittings through a hot-melt socket fusion machine, and then quickly attaches them after the surface is melted. OD20mm to OD110mm HDPE pipe and HDPE pipe fittings use this socket fusion connection.
3. HDPE pipe electrofusion connection: Electrofusion connection is to insert the two pipe ends to be connected into the sleeve with the electric heating wire embedded, pass the electric current through the electric heating wire, heat the pipe fittings to the melting temperature and fix it to the interface for cooling, then forming a tight and firm joint. It includes electrofusion socket connections and electrofusion saddle connections. The guarantee of the stable quality of the electrofusion connection mainly depends on strict compliance with the prescribed operating procedures and the quality of the electrofusion pipe fittings.
4. HDPE pipes mechanical connection: A pipe fitting that mechanically connects polyethylene (PE) pipe to another section of polyethylene (PE) pipe or pipe accessories. It can be assembled at the construction site or pre-installed at the factory. The methods are threaded connection, PP quick connector connection, welding or flange (including PE flange) and metal parts to connect and assemble.
