As a High Flexibility UHMWPE Pipe Suppliers, share with you. UHMWPE pipes are thermoplastic engineering plastics with an average molecular weight greater than 2.5 million polymerized by ethylene and butadiene monomers under the action of a catalyst. There is a big difference between ultra-high molecular weight polyethylene pipes and ordinary plastic pipes. The comprehensive performance of ultra-high molecular weight polyethylene pipes is better than ordinary plastic pipes and is used as wear-resistant pipes.
UHMWPE Dredging Pipe
UHMWPE Pipe's high molecular weight and highly entangled segment molecular structure gives it excellent mechanical properties and super anti-sliding friction, and its chemical stability is also excellent, except for slight corrosion of certain strong acids under high temperature conditions , Are not subject to the corrosion of general lye and acid. Scientific research results show that the ultra-high molecular weight polyethylene pipe has an anti-aging life of more than 50 years under natural light. Even if it is operated in the cold condition of minus 269°C, its wear resistance and impact resistance are basically unchanged, energy saving, environmental protection, and economic and efficient The characteristics are obvious.
Ordinary traditional plastic pipes have some defects, such as easy aging, no wear resistance, no impact resistance, etc., and now with the development of technology, the ultra-high molecular weight polyethylene pipe materials can be applied to the following areas: can be used as a belt Conveyor skirt, coal bunker lining, spiral transmission equipment protective edge and lining, coal chute lining, tumbling roller sleeve, stern tube bearing, etc. The ultra-high molecular weight polyethylene pipe not only has wear resistance 4 times to 7 times that of steel pipe, but also 10 times that of ordinary polyethylene and polypropylene, and under cold conditions of minus 269℃, wear resistance and impact resistance remain unchanged .
The ultra-high molecular weight polyethylene pipe has extremely high impact resistance. Among the existing engineering plastics, this product has the highest impact toughness value. Many materials will crack, break, break or fatigue due to surface stress during severe or repeated explosions. The ultra-high molecular weight polyethylene pipe is subjected to the cantilever beam impact test according to the GB1843 standard to achieve no damage.
UHMWPE pipes are resistant to aggressive chemical substances. Except for the slight corrosion of certain strong acids at high temperatures, they are not corroded in other alkaline and acid solutions. It can be used in concentrated hydrochloric acid with a concentration of less than 80%, and its performance is quite stable in sulfuric acid with a concentration of less than 75% and nitric acid with a concentration of less than 20%.
