Detailed Description
Technical Parameters of Steel-plastic composite:
1, High wear resistance: molecular weight of UHMW-PE pipe up to 250 million or more, wear resistance is 4 --- 6 times of the ordinary steel pipe
2, High impact resistance: according to GB1843 standard Izod impact test without damage
3, Corrosion resistance: UHMW-PE pipe is saturated molecules structure, can be resistant to erosion of potent chemical substances
4, Good self-lubricating: UHMW-PE pipe containing a waxy substance, the friction coefficient is only 0.219MN / m
5, The unique low temperature resistance: In the working environment temperature -269 ℃ -80 ℃, UHMW-PE pipe’s impact resistance, wear resistance unchanged
6, Difficult to scale: UHMW-PE pipe is low friction coefficient, pipe finish, with good surface of non- adhesion
7, Long Life: UHMW-PE pipe fatigue strength is more than 50 million times, more than 2 times of PE100
8, Easy installation: UHMW-PE pipe use flange connection, quick and easy, greatly reducing the cost of installing the pipeline construction.
The main material of steel-plastic composite pipe is UHMW-PE, UHMW-PE(ultra-high molecular weight polyethylene pipe)is the engineering thermoplastic that the average molecular weight greater than 2 million which is composed under the action of ethylene, butadiene monomer in the catalyst. This kind of material’s comprehensive performance is superior, it’s wear-resisting, low temperature resistance, corrosion resistance, lubrication itself and shock resistance are the highest among all of the plastic. The wear-resisting surpass PTEF, nylon and carbon steel etc. Its comprehensive performance can work in the condition of - 269 to 80℃ for a long time, wear-resisting, low temperature resistance is known as “amazing” engineering plastics. UHMW-PE engineering plastics pipe technology has matured gradually in China, more and more projects start to use this kind of wear-resistant material, and it becomes a new engineering thermoplastics with moderate price and excellent performance. It can be widely used in mining, mineral powder, pulp, tailings discharge pipeline), metallurgy, electric power, petroleum, textile, papermaking, food, chemical, mechanical, electrical and other industries.
