UHMW PE pipe for power industry
Product Introduction
Ultra-high molecular weight polyethylene (UHMWPE) is a kind of thermoplastic Industrual plastic whoes average molecular weight over 5 million, polymerizes by monome of ethene and butadiene at the work of catalyzer. The product has overall performance, its performances like anti-abrasion, low temperature resistance, anti-corrosion, self-lubricating, adherement resistance, impact resistance are generally acknowledged as the most excellent among plastics, so it is called "mysterious plastic"
UHMW PE have been driving much attention since it came out, however, difficulty in processing impose restrictions on its application. Until 1970s, a few developed countries begin to realize industialized production. Along with people's continuous acquainting of excellent performances of UHMWPE and increasing strength of research and development, this kind of "mysterious plastic" has began to display its functions in many fields and be more popular gradually. The period of developing and applying UHMWPE on large-scale has been coming.
Application fields:
UHMWPE wear-resisting pipe can be used widely in many fields, and it can be used in fields as below:
Electric power plant
Piping for transporting fly ash, dry powder, and slurry.
Shipping industry
For clearing shiping lane and transporting the silt.
Chemical industry
For transporting all kinds of severely corrosive fluids.
Metallurgical industry
Piping for transporting mortar. metallurgical waste. lead particles, aluminum powder
Food industry
For transporting wheat, flour, rice, soybean, grain etc.
Coal industry
For transporting heavy medium and coal-water slurry.
Construction industry
For transporting particle and slurry.
Comapared with other pipes, UHMW PE Wear-resisting Pipe has superexcellent properties as follows:
High wear resistance
Its abrasion index is minimum among the pipeline materials.
The wear resistance is 4-10 times higher than steel pipe and other plastic pipes.
No sclaing
It has good lubricity and inadhesion.
Flow velocity of medium surpasses 2.3 meters/second, so no scaling.
Its roughness is 1/6 of steel pipe, so flow resistance is small, and its inside diameter can be designed to be smaller than steel pipe by 15.4%.
It can greatly reduce descaling cost and avoid secondary pollution.
High corrosion resistance
Very high stability of molecular structure.
No electrochemistry corrosion
Corrosion resistant to various chemical mediator.
High shock resistance
According to the standard of CB/T1043, no fracture occurred in simple-beam impact testing.
Flexibility
Elongation at break is greater than 350%.
No fracture in crustal subsidence, thus avoiding accidents.
Molecular weight
Molecular weight can reach up to about 500 million.
Weather resistance
High molecular weight with few unsaturated gene in molecular chain, thus high stability.
It has prominent anti-aging capability.
Long service life
Its performance is better under cryogenic circumstance.
Environment friendly and no pollution
This product conforms to National Standard for Hygienic Safety Evaluation of Equipment and Protective Materials in Drinking Water (2001)
Economical
Light weight and convenient transportation.
It doesn't need for any antiseptic treatment and its installation cost is low.
It doesn’t need cleaning or need few cleaning
It has long life span and its cost-effective is 6 times higher than steel pipe.
Ohers
Besides, this product also has other properties of shock resistance, sound attenuation, non-absorbency, low density, environmental stress crack resistance, rapid cracking resistance etc.
