The full name of high molecular weight polyethylene pipe is ultra-high molecular weight polyethylene (UHMW-PE) pipe. It is a new type of plastic pipe that is wear-resistant, impact-resistant, corrosion-resistant, absorbs impact energy, does not scale, does not absorb water, and has a very small self-lubricating friction coefficient.
Ultra-high molecular weight polyethylene pipe was listed as a national key promotion plan for scientific and technological achievements by the Ministry of Science and Technology's National Science and Technology Document (2000) No. 056 in 2001. It belongs to new materials and new products in the chemical industry.
1. High wear resistance
It greatly improves the service life of the pipeline. And it can improve the transportation efficiency by about 20% compared with steel pipes.
2. Corrosion resistance
No anti-corrosion paint is required during construction.
3. Anti-aging
Due to its stable properties, it has strong weather resistance and good anti-aging properties. It can be buried on the ground or underground and will not age for 50 years.
4. Anti-adhesion
Ultra-high molecular weight polyethylene has self-lubricating and non-adhesive properties, and a small friction coefficient, so the flow resistance is very small, and its inner diameter design can be reduced by about 15% compared with steel pipes.
5. High impact resistance
Ultra-high molecular weight polyethylene has the highest impact resistance and impact energy absorption among plastics. It is difficult to crack whether it is a strong external impact or an internal pressure fluctuation. Its impact strength is 10 times that of nylon 66, 20 times that of polyvinyl chloride, and 4 times that of polyethylene. Especially in low temperature environments, its impact strength reaches the highest value. Its flexibility can provide extremely safe and reliable protection for the conveying system. Due to its high impact energy absorption value, it is particularly suitable for conveying flake and granular materials, reducing breakage and reducing conveying noise.
6. Hygienic and non-toxic
It can replace stainless steel pipes for conveying materials in the food and pharmaceutical industries.
7. Chemical stability
It can convey various corrosive media and organic matter.
8. High internal pressure resistance
It can transport various materials at high pressure.
9. Lightweight
UHMWPE pipes are one eighth of the weight of carbon steel and stainless steel, which brings great convenience to loading, unloading, transportation, installation and use.
10. Economic efficiency
UHMWPE pipes are easy to install. They adopt flange or electric heat melting welding connection process, which is safe, reliable, fast and simple. No anti-corrosion measures are required. The installation is labor-saving and labor-saving, which greatly reduces the installation cost. In addition, the comprehensive performance comparison shows that the economic benefit is more than 6 times that of steel pipes.
1. Flange connection
Specially treat the ultra-high pipes and connect them together with flanges.
2. Welding
UHMWPE pipes are connected together by special welding methods.
3. Install according to user requirements.
In the pipeline transportation of powdered solids and slurry solid-liquid mixtures in many industries of the national economy, there are a lot of problems such as wear, corrosion, scaling, etc. that need to be solved urgently. Taking advantage of the unique properties of UHMW-PE pipes, they are mainly used in the following fields: Transportation of solid particles and powders: Taking advantage of the wear resistance, impact resistance, self-lubrication, anti-adhesion, sanitation and non-toxicity, impact absorption, good noise reduction effect, good resistance to environmental stress cracking, and lightness of UHMW-PE pipes, they can be used in various industries, such as food processing, oil raw material processing, building materials and chemicals, mineral powder, raw salt, etc. The wear-resistant transportation of solid particles and powders can replace steel pipes, special steel pipes, and stainless steel pipes in terms of performance or price.
Using the advantages of UHMW-PE pipes, such as wear resistance, impact resistance, self-lubrication, no scaling, good environmental stress cracking resistance, high internal pressure resistance, and lightness, it can replace steel pipes and expensive alloy steel pipes, stainless steel pipes, etc., and be used for the transportation of slurry solid-liquid mixtures in various industries to solve the problems of pipe wear, corrosion and scaling during the transportation process.
Using the advantages of abrasion resistance, impact resistance, low temperature resistance, self-lubrication, good environmental stress cracking resistance, high internal pressure resistance, and lightness, it can be used for fluid transportation in various industries, such as: transportation of various corrosive media in the chemical industry; transportation of crude oil and refined oil in the petroleum industry; pipelines and seawater utilization for ships and ports in coastal areas (where there is a large amount of halogen-containing air and seawater that seriously corrodes steel pipes); water supply and drainage for municipal engineering.
UHMW-PE pipes have excellent impact resistance, corrosion resistance, environmental stress cracking resistance, rapid cracking resistance, good flexibility, excellent low temperature resistance, and can resist freezing damage. They can also withstand a certain degree of impact and deformation without breaking when facing mechanical vibration, foundation settlement or earthquake.
