7. Standard: GB/T 13663-2000
8. Certification: ISO 9001
Applications: suitable for conveying at 50-150 medium, widely used in city central heating field, oil and natural gas business, anti-corrosion and thermal pipeline engineer, water supply, industries liquids transportation, sewage conduit
Advantages:
1. Nontoxic, no heavy metal additives, no fouling, not breed bacterium
2. Corrosion resistant: PE is inert material and it can resist the corrosion of many chemical mediums or electron chemical corrosion, except for few strong oxidants
3. High strength, good performance to resist the environmental stress cracking, good creep resistance
4. Good flexibility: small diameters PE pipe for water supply can be coiled and supplied for longer length, which saves a large number of fittings, PE pipe can be easily shifted according to requirement of the projects
5. Lightweight, simple safe and reliable welding technique, convenient construction, whole engineering
6. Smooth interior wall, small water resistance, high flow capacity
7. Long service lifespan: up to 50 years under normal conditions
8. Recyclable, benefit to the environment

1. Economic: with low cost than other same specifications plastic pipes, lightweight, transportation, construction, management and maintenance of provinces expenses is convenient, large diameter, ring high stiffness
2. Excellent corrosion resistance: won't be sewage and waste water and chemical corrosion and won't be soil rot in material and corrosion, also won't be plant root destruction
3. Aging resistance: pipe is commonly black and can withstand piled up and construction process of sunlight straight bask in
4. Wear-resisting superior performance
