PVP-X00-CN 100 (PE80) Water supply (1.25 MPa)
1. Properties of Ginde hdpe pipe for water supply
The polyethylene water supply pipe is a new product formed from extruding, taking the high quality polyethylene resin as main material, adding necessary assistant such as antioxidant, ultraviolet absorber and so on. The polyethylene water supply pipe has application history of forty years in abroad. It is perfect choice in many pipelines by the approving of practice. It can be used widely in many kinds of pipeline projects with the working pressure of 0.32MPa~1.6MPa and the working temperature of -20oC~40oC, such as municipal water supply, drainage, petrochemical industry, mine, irrigation of agricultural land, drain contamination, mortar transportation, landfill of refuse and so on.
The "Ginde" brand high density polyethylene pipeline made of inward material by Ginde group has many advantages, such as good chemical performance resistant, good electric insulation, corrosion proof, no rust, convenient for construction, quick maintenance and so on. The water supply tubing is produced and accepted according to the GB/T13663-2000 "Polyethylene (PE) tubing for water supply" Through the spot checking of the national plastic product supervision checking testing center, the "Gind" brand polyethylene water supply pipe has reached or exceeded the national standard reques

1The advantages of the PE tubing
1.Excellent physical characteristics
The inward high quality polyethylene used by the Ginde polyethylene water supply tubing has good rigidity and intensity, and also has good suppleness and anti-creep, and the hot-melting performance is good, which is convenient for the mounting of the plastic pipeline.
2.Corrosion resistant, long lifespan
In the coastal areas of our country, the ground water level is higher, the ground humidity is great, the seamless steel pipe must be used to prevent corrosion, and the lifespan is only 30 years. And the PE pipes can proof corrosion many chemical mediators, without need for the corrosion proof treatment. In addition, it will not improve the alga, bacteria or epiphyte growing. The lifespan can reach up to 50 years under the normal condition.
3.Good toughness and suppleness
PE pipe is high toughness tubing, the breaking extension of which exceeds 500%. It has very strong adaptability to the dropping with uneven base and dislocation, good shock resistance. So it is suitable to apply in the area with earthquake dangerous. It has proved by the practice all of the world that the PE pipe is the pipeline with excellent shock resistance.
In addition, the suppleness of the PE pipe make the PE pipe coil up (especially the PE pipe with small pipe diameter), which decreases a lot of connection pipe fittings. The direction of the PE pipe is easily changed according to the requirements of the constriction method. In construction, the allowable bending radius of the pipe can bypass obstacle, which can decrease the construction difficult.
4.Great negotiability and economical
The inner wall of the PE pipe is smooth, no crust. The equivalent absolute rough radio of the inner wall is 1/20 of the steel.
The negotiability of the PE pipe under the same pipe diameter, same length, the same pressure is about 30% more than that of the steel pipe, so the economic advantage is obvious. Compared with the metal pipeline, the PE pipeline can decrease about one-third of the project investment (the cost of the pipe with the diameter more 2000 mm). The small bore tubing which can be coiled up can decrease the construction cost further.
5.Convenient for connection, easy to construct, many methods
The PE pipe is light, convenient for transportation, easy to weld; the weld-throat section is few. When the pipeline is longer, the requirements for the PE pipe laid by the coil pipe (namely the pipe with the diameter less than 63mm generally) is much lower than the steel pipe. In addition, the method of the pipe dropping can be adopted for laying under water, decreasing largely the constructional difficult and project cost.
6.Good sealing performance
The PE pipe adopts the melting connection, guaranteeing the identity of the joint material structure and the pipe body, realizing the integration of the joint and the tubing. The tensile strength and burst strength are both higher than the pipe body, which can effectively resist the ring stress and axis stress from the inner pressure. Compared with the rubber joint or other mechanical joint, there is no the leakage dangerous of the distortion joint, the sealing performance is perfect.
7.Convenient for maintenance, can be repaired and mounted without stopping the water and gas
8.Good stress resistant craze performance
The PE pipe has low gap sensitivity, high shear strength, excellent scar resistant ability and outstanding environment resistant stress,
9.Good low temperature shock resistance;
The low temperature brittle temperature of the polyethylene is very low, can be used in the temperature range between -20~40oC. When constructed in winter, because of good shock resistant performance, the pipe will not brittlecrack.
10.Good abrasion resistance
It can show from the abrasion resistance performance test of the polyethylene pipe and the steel pipe: the abrasion resistance of the polyethylene pipe is four times of the steel pipe.
11.Low flow resistance
The inner wall of the PE pipe is smooth. The smooth inner wall and the non- adherence performance can guarantee the transmitting capacity of the PE pipe is higher than traditional tubing, and at the same time decrease the pressure loss of the pipe and water transportation energy consumption.
12.Many new constructional methods
Besides the traditional constructional methods, the PE pipeline also has many constructional methods, such as top pipe, directional drilling, conduit, crack pipe and so on, which is the only choice fro some place where the digging is not allowed, so the PE pipeline is more widely used.
