To understand the connection method of HDPE silent drain pipe, we must first know what is HDPE drain pipe, what properties does it have, and what fields are it commonly used in? The following introduces the characteristics of HDPE mute pipe, as well as its various connection methods.
HDPE drainage pipe is a kind of thermoplastic pipe, the matrix is mainly high-density polyethylene resin, and it is extruded and molded for plastic pipes without internal pressure. The raw material is white powder or granular, non-toxic, tasteless, and has the advantages of corrosion resistance, aging resistance, impact resistance, cracking resistance and so on. There are 4 general connection methods:
1, hot melt butt welding
This connection method is composed of hydraulic operation console, welding frame and fixture, electric heating plate, electric milling cutter and other parts. When welding, the structure is pressed with a ferrule mica sheet to position the pipe. Heat the PE pipe and the pipe fittings to be connected under pressure, after reaching the hot melt temperature, remove the heating tool, apply pressure to connect the two molten surfaces together, and keep them under stable pressure for a period of time until the joint cools, which is automatically controlled by computer throughout the process.
2, socket flexible connection
socket flexible connection is a new type of connection, it is to directly insert one end of the pipe into the special socket of the pipe or pipe fittings, through the locking ring in the socket compression and pull-out, rubber sealing ring compression seal, to achieve the purpose of connecting pipes and pipe fittings. Non-rigid connection, good seismic performance; It can be disassembled and easy to maintain; High raw material characteristics and tensile resistance.
3, socket type electric fusion connection
socket type electric fusion connection is to use the embedded resistance wire (generally copper wire) of the electric fusion pipe fittings and the connection part of the pipe close contact energized, through the embedded resistance wire heating the connection part, so that it is melted and connected as a whole, until the joint cools.
4, grooved clamp connected to
HDPE trench clamp connected to silent pipe, quick installation and detachable. There is no need for maintenance and replacement during the whole service life, and the service life is more than 50 years, which is suitable for floors, five-star hotels, residences, hospitals, chemical plants, laboratories, etc.
