As a UHMWPE Tube Manufacturers, share with you.
Ultra-high molecular weight polyethylene pipe has a lighter specific gravity than water, can float freely, has good toughness, acid and alkali resistance, impact resistance, and aging resistance, and is often used for the transportation of some solid-liquid mixtures.
UHMWPE Dredging Pipe
1. In the slurry conveying industry, the slurry is worn faster and corrosive during the slurry conveying process, and the requirements for the pipeline are relatively high. Many industrial and mining enterprises choose to use ultra-high molecular weight polyethylene pipes to convey the slurry.
2. In the river dredging and dredging industry, ultra-high molecular weight polyethylene pipes can be used for dredging and dredging. Dredging of rivers, lakes and reservoir areas is an important and stable part of China's annual dredging project. With the rapid development of the economy, the construction of port and channel engineering has continued to improve. Port desilting and cleaning are the main issues for port maintenance. In order to reduce sediment deposition in the reservoir area and ensure long-term and safe operation of water conservancy projects, dredging and silting works in the reservoir area are also essential.
The friction coefficient of UHMWPE Dredging Pipe is small, and the ultra-high molecular chain is particularly long, which makes the wear resistance of ultra-high molecular weight polyethylene pipes very good. In addition to the transportation of solid-liquid mixtures, many places with high requirements for pipeline wear resistance can be selected.
Features and benefits
[1] Extremely high abrasion resistance. The unique molecular structure of UHMW-PE products make it extremely resistant to sliding friction. The wear resistance is 6.6 times higher than that of general alloy steel and 4-7 times that of steel pipe.
[2] Extremely high impact resistance. This product has the highest impact on toughness value among the existing engineering plastics. This product is tested according to GB1843 for cantilever impact tests to achieve no damage.
[3] Excellent chemical stability, this product can withstand the attack of strong chemicals, except for some strong acids that have slight corrosion at high temperatures, they are not subject to corrosion in other alkali and acid solutions.
[4] Good self-lubricating property, because this product contains a waxy substance, and self-lubricating is very good. The coefficient of friction (196N, 2 hours) is only 0.219MN / m (GB3960), so it can not only move freely but also protect related workpieces from wear or strain.
[5] Unique low temperature resistance, this product has excellent low-temperature resistance, and its impact resistance and wear resistance are basically unchanged at minus 269 degrees Celsius. It is the only engineering plastic that can work at temperatures near absolute zero.
[6] It is not easy to scale. Because of its small friction coefficient and non-polarity, this product has good surface non-adhesion.
[7] The best resistance to environmental stress cracking; the elastic modulus is more than 1.5 times that of PE100; the fatigue strength is> 500,000 times.
