The polyethylene water supply pipe is a new product formed form extruding, taking the hign quality polyethylene resin as main material , adding necessary assistant such as anti-oxidant, ultraviole absorbor and so on, The polyethylene water supply 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 ko=inds 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,petrochemicalindustry,mine,irrigation of agricultural land,drain contamination,mortar trandportation, landfill of refuse and so  on.
     The "taijilong"brand hign denisity polyethylene pipeline made of inward material by Changxing LTD.,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 produced and accepted according th the GB/T13663-2000 "Polyethylene(PE) tubing ofr water supply",Through the spot checking of the nation plastic product supervision checking testing center.,the"taijilong" brand polyethylene water supply pipe has reached or exceeded the nation standard request.

the advantages of the PE tubing
11excellent physical characteristics
The  Inward hign quality polyethylene used by the taijilong 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 areasof our country, the ground water level is higher, the ground humidity is  heavy, the seamless steel pipe must be used to prevent corrosion, and the lifeapan is only 30years.and the PE pipes can prevent corrosion, without need the corrosion -prevent treatment, In addition, it will not improve the alga, bacteria or epiphyte growing, the lifespan can reach upto 50 years under the normal condition.
3. Good toughness and supplness

PE pipe is hign 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 earth-quake dangerous, It has proved by the practice all of the world that the PE pipe is the pipeline with excellent shock resistance. in additation the supplness of the pipe make the PE pipe coil up, with decrease  a lot of connection pipe fittings, the direction of the PE pipe is easily changed according to the requirement of the construction method, the allowable bending radius of th epipe 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 1/20fo the steel's.the nogotibility of the PE pipe under the same pipe diametert, same length, the same pressure is about 30%
