Product Description

Physical and mechanical properties
 

Use symbol	Test temperature (°C)	Short-term hydrostatic pressure and burst pressure / Mpa	Time / h	Performance requirements
LT	20°C	Nominal pressure×2	1	Not rupture, no leakage
	20°C	Burst pressure ≥Nominal pressure×3		Bursting
Q	20°C	Nominal pressure×1.6×2	1	Not rupture, no leakage
	20°C	Burst pressure ≥Nominal pressure×3.3×1.6		Bursting
Thermal stability (200°C)				>20min
Note: When dn ≥ 250, there is no mandatory requirement of burst pressure test

 
Technical requirements
The color is generally black. Also can be decided according to customer negotiation.
The inner and outer surface of the tube should be glossy and smooth. Tiny pits and bumps are allowable. Air bubble, breach, decomposition color line and obvious wound are not allowable. The both ends of the tube should be cut flat.
  
 
 
 
Product characteristic
1.It has higher strength, stiffness, impact resistance than plastic pipe.
2.Corrosion resistance on both surfaces, it has same corrosion resistance with plastic pipe.
3.High work temperature, low thermal conductivity, heat insulation for outer wall is not required when it is used in winter, and no moisture condensation when it is used in summer.
4.Smooth and neat inner wall, no scaling, head loss is 30% lower than steel pipe.
5.Pipe connection adopts electric melting connection which is the mature technology, The electric melting joint has strong axial tension resistance. The pipe fittings have many specifications.
6.Light weight, easy transportation and construction. Overall reliability for pipes is high.
7.Low cost, health and non-toxic, it is the best substitute for galvanized pipe.

Introduction:
Product carried standard: CJ/T189-2007 "Steel Wire Skeleton Plastic (Polyethylene) Compostie Tubing and Pipe Fitting", Q/WXX001-2010 "Coal Mine Underground Steel Wire Skeleton Polyethylene". The composite tubes of the smae model and different pressure levels have different wire diameters and net papameters. Nominal pressure is the maximum using pressure of the tubing conveying water medium at 20°C. If the medium temperature changes, it should be corrected according to nominal pressure correction coefficient.
Tubing color is generally black. Water supply tubing is black or blue. Black tube should have blue color bar;
Tubing fixed length: 6m, 10m or decided according to customer requirements and transportation conditions.
