Model Number: 400mm HDPE water pipe
Brand Name: YOST
Key Specifications/Special Features:
OverviewThe polyethylenewater supply pipe is a new product formed from extruding, taking the high quality polyethylene resin as main material, adding necessary assistant such as anti-oxidant ultraviolet absorber and so on.The polyethylene water supply pipe has application history of forty years abroad.It is perfect choice in many pipelines by the approving of practice.It can be widely used in many kinds of pipeline projects with the working pressure of 0.32MPa~1.6MPa and the working temperature of -20℃~40℃, such as municipal water supply, drainage, petrochemical industry, mine, irrigation of agricultural land, contamination drainage, mortar transportation, landfill of refuse and so on.Advantages of HDPE Pipes
1.Great negotiability and economicalThe inner wall of the HDPE pipes is very smooth.
The equivalent absolute rough radio of the inner wall is 1/20 of the steel.
The price of the HDPE pipes under the same pipe diameter, length and pressure is about 30% of the steel pipes.
2.Convenient for connection, easy to constructThe HDPE pipe is very light.
It is convenient for transportationand easy to weld.
The weld-throat section is few.
3.Good sealing performanceThe HDPE pipe adopts the hot melting connection which guarantees the identity of the joint material structure and pipe body and realizes the integration of the joints and the tubing.
The tensile and burst strength are bothhigher than the pipe body, which effectively resist the ring stress from the inner pressure.
4.Good stress resistant performanceThe HDPE pipe has low gap sensitivity, high shear strength, excellent scar resistant ability and outstanding environment resistance stress.
5.Low temperature shock resistanceThe brittle temperature of the polyethylene is very low which can be used in the temperature range between -20℃~ 40℃.
6.Good abrasion resistanceIt can be shown in the abrasion resistance performance test of the polyethylene pipes and steel pipes.
The abrasion resistance of the HDPE pipe is 4 times of the steel pipe.
Application Area1.Town Water SupplyWith integrative advantages of safe, health and continent for construction, the HDPE pipeline has been the perfect tubing for the town water supply.
2.
Food, Chemical Industry AreaWith the unique chemical corrosion performance, the HDPE pipe can be used in the transportation and emission of many acid, alkali and salt solutions.
The working life is long, the cost and maintenance discharge is low.
Pipe ConnectionThe ways of connecting HDPE pipes can be divided into electro-fusion and butt fusion.
