Polyolefin composite wear-resistant pipes use polyolefin wear-resistant material as the wear-resistant layer and are compounded with the base pipe through co-extrusion. The long-term operating temperature is below 45 °C and are suitable for transporting various liquids, slurries, etc. that have wear-resistant requirements. Ultra-high performance wear-resistant pipes in granular solids.
2.1 Polyolefin wear-resistant material:
A material mainly made of polyolefin that has both wear resistance and processability.
2.2 Wear-resistant layer:
The inner layer of the pipe is made of polyolefin wear-resistant material with a certain thickness and wear resistance.
2.3 Base tube:
The pipe body of the polyolefin composite wear-resistant pipe is obtained by removing the wear-resistant layer.
2.4 Polyolefin composite wear-resistant pipe:
The pipe is made of wire mesh skeleton polyethylene pipe as the base pipe and co-extruded with polyolefin wear-resistant material.

Note:
1. This series of pipes are mainly used in fire pipes, high pressure water delivery in mines and other fields..
2. The nominal pressure refers to the maximum allowable working pressure of the pipe conveying water at 20ºC.
3. The weight of the HDPE material is calculated according to the average density of 0.95g/cm³, and the outer diameter and wall thickness are taken as the nominal value plus half of the limit deviation.
We has passed ISO9001:2015 quality management system certification, ISO14001:2015 environmental management system certification, ISO45001:2018 Occupational health and safety management system certification. In addition, we qualify the member cooperation unit with the State Grid Corporation of China and signed a long-term supply contract with the State Grid of China.
Features
2 . High corrosion resistance: acid resistance, alkali resistance, chemical corrosion resistance, electrochemical corrosion resistance;
4 . Good toughness and high composite strength : three-layer co-extrusion, elongation at break >1000% ;
Wire mesh frame tube is widely used in fire pipes, high pressure water delivery in mines and other fields.
The pipe with the same diameter of DN315mm or above can save 15%-20% of the material compared with the ordinary PE pipe, which is a energy-saving product vigorously developed recently.
Wire mesh frame tube connection construction is very simple, need only small capacitance of the welding machine can be connected, to improve the construction efficiency, speed up the construction schedule.
