pe tube

It is polyethylene plastic, the most basic plastic, used in plastic bags and plastic wrap. It is a highly crystalline, non-polar thermoplastic resin. The original appearance is milky white, and is translucent to a certain extent in thin sections. It has excellent resistance to most domestic and industrial chemicals.
Pipe welding, pipe butt welding, this method provides the highest reliability and pressure within a range of diameters and the pressure process heats the ends of the pipe, using a tool called contact mirror under the definition of pressure and temperature . The ends are contacted quickly and kept under pressure during the cooling process.
Pipes include medium density polyethylene pipes and high density polyethylene pipes. Divided into and columns according to wall thickness. The former is suitable for transporting gaseous artificial coal gas, natural gas and liquefied petroleum gas, while the latter is mainly used for transporting natural gas. Compared with steel pipes, the construction process is simple and has a certain degree of flexibility. More importantly, it does not need anti-corrosion treatment, which will save a lot of processes. The disadvantage is that the mechanical properties are not as good as those of steel pipes. During construction, special attention should be paid to the safety distance of thermal heating, and they cannot be exposed to the air and sunlight. They are also sensitive to chemicals to prevent leakage of sewage pipes from causing damage.
