Product Description
Sand discharge pipe is made of high density polyethylene in addition with a small amount of antioxidants, anti-UV absorbent and pigments. It is especially suitable for sand slurry pumping.
High wear resistant sand discharge pipe have unique features for a long life span, corrosion free, abrasion resistance, low maintenance performance even in the sea, lake and other liquid bodies. High density sand discharge pipes are fitted with welded stub-ends&steel flanges. It’s made from virgin compounded materials for high performance.
Quantity of ultrahigh wear-resisting molecular weight is more than two million. Abrasion index is very small. The abrasive resistance is 6.6 times than ordinary alloy steel, 27.3 times that of stainless steel, 4-7 times 17.9 times that of phenolic resin, 6. 4 times that of polyethylene.
Sand discharge pipe Features
1.Sand discharge pipe has ultrahigh shock resistance. It accords with standard of GB1843. It has the best impact toughness value in existing engineering plastics.
2.Sand discharge pipe has good property of corrosion resistance. It can prevent eroding from chemicals and withstand hydrochloric acid with less than 80% concentration.
3.Good self lubricity. Its surface is non-cohesive and non-scaling. It can’t form dirt in the medium with PH value of 9 or above.
4.Good low temperature resistance for – 50°C to -80°C.
5.Good cracking resistance. It has best property of environmental stress resistance. Environmental stress cracking resistance is above 4000h (above 2 times of PE100).
6.Installation is very simple. Specific gravity is 1/8 of steel pipe.
Applications of Sand discharge pipe
1.Municipal water supply, gas supply and agriculture irrigation etc.
2.Commercial or residential water supply.
3.Industrial liquids transportation.
4.Sewage treatment.
5.Food and chemical industry.
6.Replacement of cement pipes and steel pipes.
7. Silt and mud transportation.
8.Garden green pipe networks.
