Product Details
Description
PE resin is polymerized by monomer ethylene. Due to different polymerization conditions such as pressure and temperature during polymerization, resins of different densities can be obtained. Therefore, there are high-density polyethylene, medium-density polyethylene and low-density polyethylene. The point of ethylene. When processing different types of HDPE plastic tubes, according to their different application conditions, different resin grades are used, and the requirements for extruders and molds are also different.
Internationally, the materials of HDPE plastic tubes are divided into five grades: PE32, PE40, PE63, PE80, PE100, and the materials used for gas pipes and water supply pipes are mainly PE80 and PE100. my country has no classification of special materials for polyethylene pipes, which makes it difficult for domestic polyethylene gas pipe and water pipe manufacturers to choose raw materials, and it also brings a lot of hidden dangers to the use of polyethylene pipes.
Therefore, the National Bureau of Standards has made a lot of revisions in the new GB/T13663-2000 standard, which stipulates that the different grades of PE80 and PE100 of the water supply pipe correspond to different pressure strengths, and remove the tensile strength performance in the old standard, and increase the fracture Elongation (greater than 350%), which emphasizes the basic toughness.
Feature
1. Low water flow resistance: HDPE plastic tubes have a smooth inner surface, which ensures that HDPE pipes have a higher conveying capacity than traditional pipes, and also reduces the pressure loss of the pipeline and the energy consumption of water transmission.
2. Convenient handling: HDPE plastic tubes are lighter than concrete pipes, galvanized pipes and steel pipes. It is easy to handle and install. Lower manpower and equipment requirements mean that the installation cost of the project is greatly reduced.
3. A variety of new construction methods: HDPE plastic tubes pipelines have a variety of construction technologies. In addition to traditional excavation methods, a variety of new non-excavation technologies such as pipe jacking, directional drilling, and liner can also be used. , Split pipe and other methods for construction.
Installation Attention
1. It is recommended to take sheltering measures for outdoor laying in the open air and places exposed to sunlight.
2. Buried HDPE water supply pipelines, pipelines with DN≤110 can be installed in a serpentine shape in summer, pipelines with DN≥110 have sufficient soil resistance and can resist thermal stress, so there is no need to reserve a pipe length; in winter, there is no need Reserve the tube length.
3. When installing HDPE plastic tubes, if the operating space is too small (such as: pipeline wells, ceiling construction, etc.), electrofusion connection methods should be used.
4. When connecting hot-melt sockets, the heating temperature should not be too high or too long; the pipe fittings or pipe joints should be clean when inserting, otherwise it will cause the socket to break off and leak water
