PRODUCT INFORMATION

Chemical properties of HDPE pipe:

Polyethylene resistance to a variety of organic solvents, a variety of acid and alkali corrosion, but not oxidizing acid, such as nitric acid. Polyethylene can be oxidized in an oxidizing environment.

Physical properties of HDPE pipe:

Polyethylene in the condition of thin film can be considered to be transparent, but in the block of time, due to the presence of large amounts of crystals within the intense light scattering and opaque will happen. Polyethylene crystallization degree is affected by the number of low chain, branch chain, the more the more difficult to crystallization. Polyethylene crystal melting temperature is also affected by the number of branch chain, distributed in the range of from 90 degrees to 130 degrees Celsius, branch chain, the more the lower melting temperature. Polyethylene single crystal can usually by the high density polyethylene in more than 130 degrees Celsius environment dissolved in xylene preparation.

Specifications and connections of HDPE pipe:

 Diameter HDPE pipes from DN16 to DN315, divided into 18 levels. Pressure levels between 0.25Mpa ~ 1.0Mpa, a total of four grades.

HDPE pipe at a temperature between 190 ℃ -240 ℃ will be melted, by using this characteristic, the pipe (or tube) sufficient contact between the molten portion and to maintain an appropriate pressure, the two can be firmly integrated cooling. Therefore, PE pipe connection mode is different from U - PVC pipe, usually adopt electric hot melt connection and hot melt docking, according to the diameter size of the specific situation can be divided into: DN ≤ 63, will use the plastic hot melt socket connection;DN ≥ 75, will use the hot melt docking connection or fused socket connection.
