UHMWPE wear-resistant pipes
UHMWPE wear-resistant pipes
As a new type of engineering plastic pipe with excellent comprehensive performance, UHMWPE pipe can be used for the transportation of various liquids or solid-liquid mixtures with high corrosivity, high adhesion and high abrasion. It is used in the transportation of various acids, alkalis, crude oil, refined oil, tailings slurry, coal water slurry, power plant ash and slag discharge in mines, steel plants, thermal power plants, chemical plants, and oil fields. The service life is 6 ~ 10 times that of steel pipe under wear condition. It fully demonstrates the advantages of using ultra-high molecular weight polyethylene pipes for "energy saving, environmental protection, economy, and high efficiency".
Executive standard:
QB / T2668－2004 "Executive Standards for Ultra High Molecular Weight Polyethylene Pipe"
MT558 [1]. 1-2005 "Executive Standards for Coal Mine Polymer Pipes"
MT558.1-2005 "Executive Standards for Coal Mine Polyethylene Pipes"
GB-T13663-2000 "Executive Standards for Polyethylene (PE) Pipe for Water Supply"
MT181-1988 "Code for the safety performance inspection of plastic pipes used in coal mines"
Ultra-high molecular weight polyethylene composite reinforced pipe is divided into two layers: inner layer force ultra-high molecular weight polyethylene pipe, single-screw high-pressure extrusion molding has excellent wear resistance, small friction coefficient, non-adhesion, non-structural Good, excellent internal pressure resistance, excellent chemical stability, the outer layer is steel pipe, as a protective layer, can greatly improve the bearing capacity of the pipe, suitable for long-distance high-pressure transmission.
Advantages of UHMWPE wear-resistant pipes
In addition to its strong wear resistance, UHMWPE wear-resistant pipes also have the following characteristics:
1.High wear resistance: The service life of the pipeline is greatly improved, and the conveyance rate can be increased by about 20% compared with the steel pipe.
2.Corrosion resistance: No anti-corrosion coating is required during construction.
3.Aging resistance: Because of its stable nature, it has strong weather resistance and good aging resistance. It can be buried on the ground and underground, and it will not aging for 50 years.
4.Anti-adhesion: UHMWPE has self-lubricating and non-sticking properties, less friction coefficient, so the flow resistance is very small, its inner diameter design can be reduced by about 15% compared with steel pipe, especially suitable for conveying high viscosity mixed slurry, Conveying powdered materials easily.
5.High impact resistance: The impact resistance and impact energy absorption of ultra-high molecular weight polyethylene ranks first among plastics. Whether it is a strong external impact or internal pressure fluctuations, it is difficult to crack, and its impact strength is 10 times that of nylon 66. , Polyethylene 20 times, especially in low temperature environment, its impact strength reaches the highest value, and its flexibility can provide a very safe and secure guarantee for the conveyor system. Due to the high impact energy absorption value, it is particularly suitable for conveying flaky and granular materials, reducing fragmentation and reducing transmission noise.
6.Hygienic and non-toxic: It can replace expensive stainless steel pipes to transport materials in the food and pharmaceutical industries.
7.Chemical stability: It can transport various corrosive media and organic matter.
7.Chemical stability: It can transport various corrosive media and organic matter.
8.High internal pressure resistance: various materials can be transported under high pressure.
9.Lightweight: UHMWPE pipe is one-eighth of the weight of carbon steel and stainless steel pipes, which brings great convenience to handling, transportation, installation and use. Ultra-high molecular weight polyethylene pipes are easy to install, using flange or electrothermal fusion welding process, safe, fast, simple, no need to take anti-corrosion measures, installation labor and labor, greatly reduce installation costs, plus comprehensive performance comparison, economic benefits are More than 6 times the steel pipe.
