Ultra-high molecular weight polyethylene(UHMWPE) pipe

Ultra-high molecular weight polyethylene(UHMWPE ) pipe are a type of piping material made from high-performance thermoplastic engineering plastics with a molecular weight exceeding 2.5 million, renowned for their excellent wear resistance, corrosion resistance, impact resistance, and self-lubricating properties. As a new type of engineering plastic piping material with outstanding comprehensive performance, this product is widely used in harsh operating environment applications such as mine tailings transportation, chemical fluid transfer, crude oil collection and transportation, and powder and slurry conveyance. It can replace traditional metal pipes and conventional plastic pipes, significantly reducing maintenance costs and improving system efficiency, and can address issues such as severe pipe wear, corrosion, and scaling in the transportation of large quantities and various types of industrial materials. Product Performance: High wear resistance: The unique molecular structure of Ultra-high molecular weight polyethylene(UHMWPE ) pipe makes it possess excellent wear resistance, which is 4-7 times that of ordinary steel pipes, 6 times that of nylon, and 4 times that of polyethylene. The excellent wear resistance significantly increases the conveying capacity of the tubing and extends its service life. Corrosion Resistance: Resistant to acid, alkali, salt, and organic solvent corrosion, it has better chemical stability than materials such as nylon and ABS, and does not require additional anti-corrosion treatment. Anti-aging properties: Due to its stable nature, it exhibits strong weather resistance and excellent anti-aging properties, making it suitable for both ground and underground installation, with no aging even under sunlight for 50 years. Self-lubricating: Ultra-high molecular weight polyethylene(UHMWPE) pipe have smooth inner and outer walls, good self-lubricating properties, and a friction coefficient of only 0.219MN/m. The surface is smooth and not easy to accumulate scale, maintaining high flow efficiency for a long time. Impact Resistance: The impact test of the cantilever beam showed no damage (compliant with GB1843 standard), with an impact strength 10 times that of Nylon 66, 20 times that of PVC, and 4 times that of PE, providing extremely safe and reliable protection for the conveying system. Low-temperature resistance: Excellent low-temperature resistance performance, its impact resistance and wear resistance remain almost unchanged at -269°C, and the product has a wide temperature range, capable of working long-term within -269°C to 80°C. High pressure resistance and high toughness: The tensile strength is twice that of PE100, capable of withstanding significant fluctuations in pressure during medium transportation. Similarly, the ultra-high molecular weight polyethylene pipe has an elongation rate of ≥300%, and the pipeline and joints are not easily cracked when the application environment subsides, ensuring the normal transportation of the medium to the maximum extent.

In mining development, which type of wear-resistant pipe offers a better balance between functional adaptability and economy for long-distance transportation of media such as mineral concentrate and slurry?

SHS ceramic lined composite steel pipe exhibit high hardness and excellent wear resistance. The smooth surface of the ceramic lining, with its low roughness, reduces frictional resistance during media transport, effectively resisting wear caused by particle erosion and reducing energy consumption. In long-distance transport, it can reduce the load on pumps and save operating costs, making it a superior choice for long-distance media transport.

The oil industry deals with high-pressure transportation of sand-containing crude oil, and the sand particles are abrasive. From the perspective of compression resistance and wear resistance, which material would be more suitable?

High-pressure crude oil transportation containing sand requires a balance between pressure resistance and wear resistance. SHS ceramic lined composite steel pipe offer good wear resistance but are brittle and prone to cracking under high pressure, with only moderate pressure resistance. Hard ceramic patch composite steel pipe have good wear resistance, but the bonding strength of the laminations may be affected under high pressure, posing a risk of detachment. Bimetallic composite steel pipe have a strong base steel pipe with high pressure resistance, and the wear-resistant alloy layer addresses sand abrasion. Their overall performance is well-suited to high-pressure conditions; although more expensive, they guarantee stability under high-pressure conditions. Therefore, Bimetallic composite steel pipe remain the more suitable choice.

In the chemical industry, when transporting corrosive acid and alkaline solutions, which material is more suitable—considering both corrosion resistance and wear resistance reliability?

The core advantage of SHS ceramic lined composite steel pipe lies in the chemical stability of the ceramic lining, exhibiting extremely strong corrosion resistance to acid and alkali solutions and effectively resisting the erosion of hydrogen ions and hydroxyl ions. Simultaneously, the high hardness of ceramic provides good resistance to wear from small amounts of solid particles in solutions. In scenarios with few solid particles and moderate impact, SHS ceramic lined composite steel pipe offer the best cost-performance ratio.

Adaptability to metallurgical high-temperature dust scenarios (temperature >300°C)?

Ceramic patch tube + external insulation layer.

Alumina ceramics can withstand temperatures up to 800℃, but the steel pipe body needs to be protected against high-temperature deformation;

SHS ceramic lined are prone to cracking at high temperatures due to differences in their coefficients of thermal expansion.

In bimetallic tubes, the hardness of high-chromium cast iron decreases by 50% at temperatures above 400℃, and its wear resistance drops sharply.
