Ultra high wear-resisting pipe as a kind of excellent comprehensive properties of new type engineering plastic wear-resisting pipe, with its superior performance, can be used for all kinds of high wear resistance, high adhesion, high corrosive liquid, gas, powder conveying, object or solid-liquid mixture is widely used in mines, power plants, oil fields, dredging, alkali factory, chemical industry, aluminum industry, etc, all kinds of tailings slurry, coal-water slurry, the power plant ash discharge, crude oil, white clay, red mud, sludge discharge, acid or alkaline solutions such as transportation, under the condition of strong corrosion and high wear four to six times that of steel tube service life, fully show the application of ultra high tube “energy saving, environmental protection, economic and efficient”.
Ultra-high wear-resistant pipe application:
- thermal power generation: fly ash transport and return pipes.
- oil exploitation: long-distance transportation of crude oil and natural gas.
- coal industry: pulverized coal transport, coal water transport.
- mining industry: tailings and mud transport, underground filling pipe.
- dredging industry: transport of silt removal sand.
- chemical industry: transport of corrosive media.
- jinghu Marine salt chemical industry: Marine salt transport, brine transport.
- city: water supply and drainage, sewage reuse.
Uhmw-pe product features:
- The extremely high wear-resisting property the molecular weight of the ultra-high pipe is more than 2.5 million yuan, and the abrasion index is the smallest, which makes it have a very high anti-sliding friction ability.The wear resistance is 6.6 times higher than that of normal alloy steel and 27.3 times of stainless steel.It is 17.9 times of phenolic resin, 6 times of nylon 6, and 4 times of polyethylene, greatly improving the service life of ultra-high wear-resistant pipe.
- high resistance to impact This product in the existing engineering plastics has the highest impact toughness values, many materials in serious or repeated explosion shock stress fatigue crack, broken, broken, or surface.According to GB1843 standard, the cantilever beam impact test achieves no damage and can withstand strong external impact, internal overload and pressure fluctuation.
- corrosion resistance, uhmw-pe is a saturated molecular structure, so its high chemical stability, this product can be virulent chemical erosion resistance, in addition to some acid at high temperature corrosion, slightly in other alkali, acid from corrosion.It can be used in concentrated hydrochloric acid with a concentration of less than 80%. Its performance is quite stable in sulfuric acid with a concentration of less than 75% and nitric acid with a concentration of less than 20%.
- Good self-lubrication due to the waxy substance contained in this product, and good self-lubrication.The friction coefficient (196N, 2 hours) is only 0.219MN/m (GB3960).Self – sliding performance is superior to oil – lubricated steel or brass.Especially in the bad environment, dust, sediment, the product’s own dry lubrication performance more fully displayed.Not only can move freely, but also protect related workpieces from wear and tear.
- Unique low temperature resistance this product has excellent low temperature resistance, and its impact resistance and abrasion resistance are basically unchanged at minus 269 degrees Celsius.It is the only engineering plastic that can work at temperatures close to absolute zero.At the same time, this product in the warm sex wide, can be in for a long time – work under 269 ℃ to 80 ℃ temperature.
- Non-fouling property due to the small friction coefficient and non-polarity, this product has a good surface non-adhesion and high pipe finish.The existing materials generally scale up in medium with PH value of 9 or more, while this product does not scale up, which is of great significance to the coal ash discharge system of thermal power station.It is also very suitable for conveying pipes such as crude oil and mud.
- long service life, less unsaturated gene in molecular chain, the fatigue strength is greater than 500000 times, the optimal environmental stress cracking resistance, resistance to environmental stress cracking > 4000 h, is more than 2 times of PE100, buried with 50 years or so, still can keep more than 70% of the mechanical properties.
- installation is simple Ultra-high molecular weight polyethylene (UHMW – PE) pipe weight per unit length is only one 8 the weight of steel pipe, the loading and unloading, transport, installation is more convenient, and can reduce the labor intensity of workers, uhmw-pe pipe anti-aging sex is extremely strong, hard to age 50 years.It can be erected on the ground or buried underground.Either welded or flanged connection when installation, safe and reliable, fast and convenient, no corrosion, provincial labor, which fully reflects the use of ultra-high molecular weight polyethylene pipe “energy saving, environmental protection, economic and efficient”.
- Other features: energy absorption, noise absorption, anti-static electricity, shielding ability to electrons, non-water absorption, light weight, easy mechanical processing, colorable and other outstanding features.
