Product Description

 20 Inch HDPE Mud Sand Dredging Dredge Mining Pipe Leader Dredger

 

UHMWPE pipe is a high molecular weight polyethylene high wear resistant pipeline with molecular weight larger than 2 million 500 thousand, including polymer high abrasion elbow, wear-resistant three links and four links.

The compressive strength of ultra-high molecular weight polyethylene pipe is 2.5 times of PE80, PEl00 is 2 times, the ability of resisting environmental stress cracking is 5 times of PE100, and fatigue resistance is 30 times of PE100.

The friction coefficient of ultra-high molecular weight polyethylene pipe is only 0.07-0.11, and its molecular chain is very long. The wear resistance of pipes is 4-7 times higher than that of steel tubes and metal pipes, which is 10 times that of PE100.

In many pipe materials, the wear index is the smallest. The wear resistance is 4-7 times higher than that of steel pipe and stainless steel tube, more than 10 times higher than that of PVC pipe and polyethylene pipe, which greatly improves the service life of the pipe.

Ultra high molecular weight polyethylene pipe material is difficult to crush and form for two times after molding. Therefore, ultra high molecular weight polyethylene pipe is produced by new raw material, and no recycling material can be added to ensure the sanitation of pipeline system. And many of the common PE, PVC and other pipe manufacturers (even the national exemption products) added the recycled materials to reduce the cost.

Leader Dredger supply the best pipeline for customer.

Brief introduction of UHMWPE Pipe
Ultra-high molecular weight polyethylene (UHMWPE) is a kind of engineering thermoplastics with more than 2 million viscosity-average molecular weight,under the polymerization of ethylene, butadiene monomer in the catalyst. Ultra-high molecular weight polyethylene pipe has the superior performance such as very high wear resistance, impact resistance, excellent resistance to internal pressure strength, resistance to environmental stress cracking, eminent self-lubricating, anti-adhesion, the unique low temperature resistance, good chemical tability , easy installation and so on, and it is widely used in metallurgical mines, electric power, petroleum, natural gas, textiles, paper making, food, chemical industry, machinery, electrical and other industries.
