UHMWPE dredging sand pipe

UHMW PE pipe 1. Wear resistance; 2. Impact resistance; 3. Corrosion resistance; 4. Good self-lubrication

Feature of UHMWPE Pipe:

Quantity of ultrahighwear-resisting UHMW is more than two million. Abrasion index is very small. Its abrasiveresistance 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

(1)It improves the service life of pipeline substantially.

(2)It has ultrahighshock resistance. It accords with standard of GB1843. It has the best impact toughness value in existing engineering palstics.

(3)It has good property of corrosionresistance. It can preventing eroding from chemicals. It can withstand hydrochloric acid with less than 80% concentration

(4)It has good property of self lubricity. Frictional factor is very small. Its surface is non-cohesive and non-scaling.Its self-lubrication is better than steel or brass with oil.It can’t form dirt in the medium with PH value of 9 or above.

(5)It has very good property of lowtemperatureresistance .It can be used in the - 50°C to -80°C.

(6)It has very good property ofcrackingresistance. It has best property of environmental stress resistance. Environmental stress cracking resistance is above 4000h (above 2 times of PE100).

(7)Installation is very simple. Specific gravity is 1/8 of steel pipe. It is much safer, easier. It is antiseptic and save labor.

(8)UHMWPE Pipe is assembled with two metal activity flanges at both ends. Entire pipe has no weld joint. Both pipes are connected by bolts of activity flanges. It has steel ring inside of pipe that ensure pipe orifice will not deformate, break and drip in the process of assembling and disassembling.

Applied range:

Its property of loading capacity, impact resistance, abrasive resistance, corrosion resistance ,lowtemperatureresistance and self lubricity has increased doubled. It can be used in the fields of Petroleum, coal mine, mine, water supply, electricity, chemical industry etc.

1.transport  powder and coal ash in thermal power plant

2.transport  mine tailings and slurry ,metallurgical mines,in the mining industry

3.transport  pulverized coal and coal-water slurry of coal preparation plant in the coal industry

4.transport  mud and corrosive media with slag in the chemical

Industry

5.transport  crud oil, petroleum, food and natural gas

Because of its very good performance , safety and reasonable price, it will be used instead of metal pipe step by step in the near future.

Meanwhile, we also make UHMW composite pipe. Detailed features as following:

UHMW composite pipe is constituted of UHMWPE Pipe and carton steel. It has ultrahigh shockresistance : After added protective cover, steel pipe has much better adaptive capacity(6Mpa). It has much longer life. Disassemble is very simple. It can also be recycled.
