High density polyethylene water supply pipe is actually hdpe water supply pipe, to take high quality polyethylene resin as raw material, plus the necessary antioxidants, light stabilizer and other modifiers, by extruder extrusion made of a new type of plastic pipe commodity. Now let's talk about the advantages and disadvantages of high density polyethylene water pipes and the problems that need to be paid attention to in the use of some problems.

First, advantages of high-density polyethylene water supply pipe
1, excellent anti-leakage performance
The root cause of the water leakage problem of the water supply pipe is the micro-gap and needle hole generated in the pipe fitting forming method, but the water permeability of the pipeline is much less than that of the clay due to the uncomfortable water characteristics of the high-density polyethylene film.

2, good chemical resistance
High density polyethylene film is a raw material with better chemical stability in geomembrane materials. For example, the composition of leachate in landfill of urban waste can not pose a threat to high density polyethylene pipe.

3. Strong corrosion resistance
High density polyethylene film has strong resistance to strong oxidant, organic matter, carbonates, substituted hydrocarbons, alcohols, plant oils, lipids and other components, which can prevent the direct erosion of this compound on the pipe. It is also resistant to certain carbon oxidizing substances such as benzene, phenacetaldehyde, hexane and formaldehyde.

2. Matters needing attention in the use of high-density polyethylene water supply pipe
When the water pipe is laid outdoors, it is necessary to cover the area exposed to sunlight.
In the construction of high-density polyethylene pipeline, if the lifting space can be too small, the electrical welding pipe type interface should be selected to carry out the work.
When the hot melt socket method is selected for connection, the heating temperature should not be too high, the time should not be too long, and the temperature should be controlled at about 210 10°C, so as not to cause too much magma extrusion in the parts, so
The nominal diameter of pressure test is reduced. At the same time, the joint of the pipe and fittings should be kept clean when the socket is inserted, so as not to cause the leakage of the socket.
