Ultra-high molecular weight polyethylene (UHMWPE) is a kind of engineering thermoplastics with more than 3 million viscosity-average molecular weight. It differs from PE standard grades in its very high degree of polymerization. Ultra-high molecular weight polyethylene pipe has superior performance over conventional HDPE pipe such as very high wear resistance, impact resistance, intrinsically self-lubricating, anti-adhesion, low temperature resistance and excellent chemical resistance.

UHMW is more rigid than LDPE and HDPE, and has better abrasion resistance than PTFE.

Can be widely used in metallurgy, mining (mineral mud conveying, backfilling by grouting ),power (fly ash conveying), sand dredging pump (lake dredging mud conveying, sand pump pipe of pumping vessel), oil, natural gas, textile, papermaking, food, chemical, mechanical, electrical and other industries.

 

UHMWPE Rods Main Characteristics:
1.Extremely high wear resistance
Its wear resistance is 6.6 times higher than normal 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
2.High impact resistance: It won't damage by Cantilever beam impact test according to GB1843 standards
3.High corrosion resistance: It can withstand hydrochloric acid with less than 80% concentration
4.High-pressuer resistance: The working pressure is between 0.2Mpa to 4.0Mpa
5.Good self-lubrication: Its self-lubrication is better than steel or brass with oil
6.The unique resistance to low temperature:It can be used within -269 to 80 degrees Celsius.
7.Not easy to form dirt: It can't form dirt in the medium with PH value of 9 or above
8.Long life-span:It can maintain more than 70% mechanical properties after it is buried and used for 50 years.
9.Easy installation:The weight of unit length of UHMWPE pipe is only one-eighth of the steel pipe, it is possible whether it is welded or connected by flange

1. Paper making industry: with its performance of high wear resistance and good self-lubrication, can be used in: vacuum box panel, dehydration plank, drawknife, pressurize assembly, shaft sleeve of paper-cutting machine and so on. The thickness of UHMW-PE tube below 10mm, can be made into covering tube of strap transport and transcribing machine roller.

2. Food and beverage light industry: with its performance of high wear resistance, anti-impact resistance, inadhesion resistance, non-toxic and clean property, can be manufactured: moving plate, transport screw, gear and so on, which is easy-cleaning, long-enduring, and anti-mildew,

and be used in other clear parts.

3. Waste-water industry:

Polluting mud scraping plate of helix transportslurry pump impellerpump bearing bushgrit collection systemdefecator gearprecipitation pool scaleboard and so on.

4. Electronic Industry: Surface dealing of semiconductor process, air-pollution control system, waste-water vent control and so on. UHMW-PE, has the excellent Performance of

low-temperature resistance, which has a good ductibility in the

Liquefied helium (-269), was started to apply in the refrigeration technology and low temperature field. The latest UHMW-PE tube can be applied in semiconductor field instead of a great deal of PTFE tubes.

5. Textile industry: With its performance of high-wear resistance, anti-impact and good self-lubrication, the products, such as: strap knot, gear, cushion baffle, bearing bush and so on.

6. Sport and amusement industry: ski tools lining, assembly of track vehicle in ice and snow, earth plate of glider plane, assembly of steel ball equipment, shaft sleeve of all size, rolling ball path, accessory of mechanization sledge and so.

7. Medical industry: Body embedded substance, artificial joints, rectifying surgical machine and bracket, orientation rack of surgical machine.

Chemical and other industry: galvanization hardware, agricultural machine, shipping parts, mechanical parts of low-temperature atomic energy and so on. Mostly using of its high-wear resistance, high anti-impact resistance, anti-cold resistance, self-lubrication, electric characteristic.
