HDPE PIPE FOR WATER SUPPLY ZER HDPE pipes are manufactured in strict accordance to MS1058, and all pipes produced within our production plan bear the SIRIM trademark (license nuer PZ 1505). ZER HDPE pipes have been used extensively as water pipes in high-pressure appliions.
Yield strength/wall thickness for the pipe is designed and selected to exceed the calculated peak stress in a worst operating case condition, i.e., a drive-off or drift off. Surface casing ranges from 24″, 20″, 18⅝″, 16″ in diameter and 0.5″ to 1.25″ in wall thickness down to 13⅝ or 13⅜″ premium pipe if a slender or slim well desig n can be used.

PE & HDPE Pipe PE100 is the third generation of pipe grade PE. It has an optimum balance of three key properties: Minimum Required Strength (MRS) – this provides long-term strength and creep resistance. Stress crack resistance (sometimes referred to as slow crack growth resistance). Puhui Pipe manufacturer in China
Specified Minimum Yield Strength (SMYS) means the specified minimum yield strength for HDPE pipe manufactured in accordance with a listed specifiion 1.This is a common term used in the oil and gas industry for HDPE pipe used under the jurisdiction of the United States Department of Transportation..

The fastest growing HDPE pipe grade is PE-112 because of its tolerance to high pressure and temperature. The high-density-polyethylene pipes market has been segmented on the basis of appliion, the market is classified into agriculture, industrial, mining, water supply, oil & gas, building & construction, and sewage systems.
Yield Strength – The yield strength of the plastic is the where the material begins to deform in a plastic fashion. Prior to the yield strength, the material will act elastically meaning that if the strain were halted at any point in the elastic portion, the material would return to its original length.

The tables below calculate the safe pull strength at three yield strength conditions for the more popular sizes of HDPE conduit used in HDD appliions. 1) Handbook of Polyethylene Pipe, The Plastic Pipe Institute, Chapter 14, pg 475:
Features of HDPE pipes and fittings: Green environmental protection: HDPE pipe non-toxic, tasteless, after strict health monitoring, belongs to green building materials, never scale, can effectively improve water quality. Corrosion resistance: HDPE pipelines are resistant to corrosion by a variety of chemical media, and chemicals present in the soil do not cause any degradation to the pipeline.
