Applications:
Suitable for conveying at - 50-150 medium, widely used in city central heating field, oil and natural gas business, anti- corrision and thermal pipeline engineer,Water supply, Industries liquids transportation , sewage conduit.
Advantage:
1.Non-toxic, 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,orelectron 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.Light weight ,simple safe and reliable welding technique,convenient construction and lower cost of the whole engineering,
6.Smooth interior wall, small water resistance, high flow capacity,
7.Long service life :up to 50 years under normal conditions.
8.Recyclable, benefit to the environment
