What is the Normal Operating Temperature Range of UHMWPE Pipe?

Pulished on Apr. 09, 2020

As a UHMWPE Pipe Manufacturers, share with you. The main material of ultra-high molecular weight polyethylene pipe is ultra-high molecular weight polyethylene. The molecular formula of ultra-high molecular weight polyethylene is — (— CH2-CH2 —) — n—. Its relative molecular mass is very large, but the atoms are simple. Linear structure connected in a repeating manner. Its molecular structure determines its low temperature resistance, usually domestically produced 3.5 to 5 million molecular weight ultra-high molecular weight polyethylene pipe heat distortion temperature is about 85 ℃. The lack of high temperature resistance limits its application environment.

However, UHMWPE Pipe's low temperature resistance is very good, and its impact strength reaches a high value at minus 40 ° C. It can still maintain good performance at extremely low temperatures, and is particularly suitable for medium conveying pipes in cold areas.

UHMWPE pipe is a kind of thermoplastic engineering plastic with excellent characteristics such as wear resistance, impact resistance, corrosion resistance, stress cracking resistance, low temperature resistance, non-toxic health, etc. It combines the advantages of almost all plastics Performance, widely used in major domestic metallurgy, mining, power, coal, chemical industry and other industries, our company mainly deals in ultra-high molecular weight polyethylene series pipeline products, if you have any requirements, please call.

UHMWPE pipe is a thermoplastic engineering plastic with excellent comprehensive performance and linear structure. The UHMWPE pipeline has impact resistance, low temperature resistance, wear resistance, chemical corrosion resistance, self-lubrication, and absorption of impact energy. The performance advantages of UHMWPE pipes are listed below.

1. The wear resistance of ultra-high molecular weight polyethylene pipes is 4 to 7 times that of steel, 10 times that of polyethylene and polypropylene, and 2.3 times that of PE. It is better to transport small particle slurry such as fly ash.

2. Ultra-high molecular weight polyethylene pipe is a saturated molecular cluster structure with very stable chemical properties. It is resistant to various corrosive media and organic solvents. It is more resistant to corrosion than polyethylene, polypropylene, nylon, ABS and other plastics.

3. Impact resistance of UHMWPE pipes. The environmental stress resistance, cracking ability, and scoring resistance rank first among various types of plastics. Among them, the impact strength is more than 10 times that of PE100 at room temperature.

4. Ultra-high molecular weight polyethylene pipe is non-sticky, its chemical and physical polarity is lower than ordinary plastics, and it is difficult to attach scale deposits. As long as the slurry flow velocity reaches 2.3 to 4.6 meters per second, scaling is difficult to form. Even if it slowly accumulates to form a scale layer for a long time, it is not firm and easy to remove.
