Luoyang Guorun Pipe Industry Co., Ltd. specializes in the production of various specifications of molybdenum ore mineral processing pipelines, molybdenum tailings pipelines, ultra-high molecular weight polyethylene pipes, ultra-high molecular pipes, ultra-high wear-resistant pipes, ultra-high pipes, steel-lined ultra-high pipes, ultra-high composite pipes, chemical pipelines, and anti-corrosion pipelines.

Ultra-high molecular weight polyethylene pipe properties:

1. High wear resistance: The friction coefficient of ultra-high molecular weight polyethylene is low, and its extremely long molecular chains make the wear resistance of modified ultra-high molecular weight polyethylene pipes 4-7 times higher than that of steel pipes and stainless steel pipes, and about 10 times higher than that of PVC pipes and polyethylene pipes, significantly improving the service life of the pipelines.

2. Corrosion resistance: Ultra-high molecular weight polyethylene has extremely high chemical stability and can withstand various highly corrosive media (acids, alkalis, salts) and organic solvents within a certain temperature and concentration range.

3. High impact resistance: Molybdenum tailings pipelines made of ultra-high molecular weight polyethylene have the highest impact resistance and energy absorption among plastics, making them difficult to crack under strong external impacts or internal pressure fluctuations. Especially in low-temperature environments, their impact strength reaches even higher values. This flexibility of ultra-high molecular weight polyethylene provides a safe and reliable guarantee for the transportation system.

4. Weather resistance and aging resistance: Ultra-high molecular weight polyethylene pipes have good weather resistance and aging resistance.

5. Flame retardancy: Special industry applications require fireproof environments, so flame retardants are added for modification, using special processing techniques to overcome the flammability of ultra-high molecular weight polyethylene, thus providing flame retardant properties.

6. Lightweight and easy to install: Ultra-high molecular weight polyethylene pipes are flexible and lightweight, weighing only 1/7 of steel pipes per meter, and can be connected using flanges, making them adaptable to various geological conditions and allowing for quick and easy connections.

Molybdenum tailings pipelines should be applied in the following fields:

Transportation of solid particles and powders: Molybdenum tailings pipelines utilize UHMW PE pipes, which are wear-resistant, impact-resistant, self-lubricating, anti-adhesive, hygienic and non-toxic, absorb shock, have good sound insulation effects, excellent resistance to environmental stress cracking, and are lightweight. These advantages allow them to be used in various industries, such as grain, food processing, oil and fat raw material processing, brewing raw materials, pharmaceuticals, building materials chemicals, mineral powder, and raw salt for the wear-resistant transportation of solid particles and powders, replacing iron pipes, steel pipes, special steel pipes, and stainless steel pipes in terms of performance or price.

Slurry transportation: Using UHMW-PE pipelines for their wear resistance, impact resistance, self-lubrication, non-scaling, good resistance to environmental stress cracking, high internal pressure strength, and lightweight characteristics, they replace steel pipes and expensive alloy steel pipes and stainless steel pipes for the transportation of slurry mixtures in various industries, solving problems of pipeline wear, corrosion, and scaling during transportation, such as coal and mining slurry transportation, water-coal slurry transportation, fly ash transportation in thermal power plants, dredging of rivers and lakes, municipal sewage dredging, and salt production and chemical slurry transportation.

Fluid transportation: Molybdenum tailings pipelines utilize wear-resistant, impact-resistant, low-temperature resistant, self-lubricating, good resistance to environmental stress cracking, high internal pressure strength, and lightweight characteristics for fluid transportation in various industries, such as transporting various corrosive media in the chemical industry; crude oil and refined oil transportation in the oil industry; pipelines for ships and ports in coastal areas (where a large amount of halogen-containing air and seawater severely corrode steel pipes); and municipal water supply and drainage. UHMW-PE pipes have unique low-temperature impact resistance and will not suffer brittle fracture under cold environments, unexpected impacts, or freezing conditions, ensuring good safety for water supply and drainage.

Gas transportation: Molybdenum tailings pipelines made of UHMW-PE have excellent impact resistance, corrosion resistance, resistance to environmental stress cracking, rapid crack resistance, good flexibility, and outstanding low-temperature resistance. They can withstand freezing damage, mechanical vibrations, ground settlement, or earthquakes, and can endure certain degrees of impact and deformation without breaking, thus providing high long-term operational safety and playing an important role in the transportation of gas, natural gas, liquefied gases, or other gases.

Application fields:

Thermal power generation: fly ash transportation, return water pipelines.

Petroleum extraction: long-distance transportation of crude oil and natural gas.

Coal industry: transportation of coal powder and water-coal slurry.

Mining industry: transportation of tailings and sludge, underground filling pipelines.

River dredging: transportation of mud and sand.

Chemical industry: transportation of corrosive media.

Marine salt chemical: transportation of sea salt and brine.
