PE water supply pipe-pe pipe fittings wholesale

There are many connection modes between PE water supply pipe and PE pipe fittings, reducing pipe and metal pipe. Users can choose the appropriate connection method according to the diameter, working pressure, place of use and other environments of the PE pipe. The common connection modes of pe pipe fittings are: hot melt butt connection, electric fusion socket connection, flange connection, steel plastic transition connection, etc.

Product Description

Hot melt connection: Hot melt connection is a special heating tool used to heat the connection part of PE water supply pipe or pipe fittings under pressure, so that the heating tool can be removed and used after melting. The pressure connects the two fusion faces and maintains them at a steady pressure for a period of time until the joint cools. Hot melt connection includes hot melt butt connection, hot melt socket connection, hot melt saddle connection.

Electrofusion connection: The electrofusion connection is in close contact with the connection part of the PE pipe or pipe fitting and the special electrofusion pipe fitting embedded in the resistance wire. PE pipe is installed by embedded resistance wire. Tubing joint locations are melted and connected until the joint cools. The electrofusion connection can be used for pe pipes of different types and different melt flow rates. Electrofusion connection is divided into electrofusion socket connection and fusion saddle connection.

Flange connection: Flange connection is mainly used for PE water supply pipe and metal pipe or valve, flow meter, pressure gauge and other supporting equipment connection. The flange connection is mainly made of polyethylene (PE), also called flange head. Flange connections, steel or aluminum back pressure sleeve flanges, steel or aluminum flanges, gaskets or sealing rings, bolts, nuts, etc. Flange connection is through the fastening bolts and nuts in close contact with the flange, in order to achieve the purpose of connection.

Steel plastic transition joint: steel plastic transition head connection is to use cold pressing or other prefabricated steel plastic transition joint to connect PE pipe and metal pipe. There are anti-pull locking rings and sealing rings on the steel-plastic transition joint, which are usually required to have good sealing performance, tensile resistance and pressure resistance, and they are larger than the PE pipe in the system.

HDPE water supply pipe:

1. Reliable connection: PE pipe systems are connected by electric melting, and the strength of the joint is higher than that of the pipe body.

2, good low temperature impact resistance: PE pipe low temperature embrittlement temperature is very low, can be used safely in the low temperature range. During winter construction, the material will not crack due to its good impact resistance.

3. Good stress cracking resistance: PE pipe has low notch sensitivity, high shear strength and excellent scratch resistance, and its environmental stress cracking resistance is also very prominent.

4, good chemical corrosion resistance: PE pipe can resist the corrosion of a variety of chemical media, the chemical substances in the soil will not cause any degradation of the pipeline. Polyethylene is an electrical insulator, so it does not decay, rust or electrochemical corrosion; in addition, it does not promote algae, bacteria or fungi growth.

5. Aging resistance and long service life: polyethylene pipes containing 2-2.5% evenly distributed carbon black can be stored or used outdoors for 50 years without being damaged by ultraviolet radiation.

6, good wear resistance: PE pipe and steel pipe wear resistance comparison test shows that the wear resistance of PE pipe is 4 times that of steel pipe. In the field of mud transportation, compared with steel pipes, PE pipes have better wear resistance, which means that PE pipes have a longer service life and better economy.

7, good flexibility: the flexibility of PE pipe makes it easy to bend, engineering can bypass obstacles by changing the way of pipe direction, in many occasions, the flexibility of the pipe can reduce the amount of pipe fittings and reduce installation costs.

8. Low water flow resistance: PE pipe has a smooth inner surface, which has a higher conveying capacity than traditional pipe, and also reduces the pressure loss of the pipeline and the energy consumption of water delivery.

9, easy to handle PE pipe than concrete pipe, galvanized pipe and steel pipe lighter, it is easy to handle and install, lower manpower and equipment requirements, means that the installation cost of the project is greatly reduced.
