Replacing steel with plastic is the trend of pipeline development in the world today. Pipeline system has significant social and economic benefits, and has been the choice of pipeline system in many countries. In the United States, Russia, Canada and other countries and regions, the use of pipelines is growing year by year, and PE steel mesh skeleton pipes occupy the second place in the use of the entire industry.
Large diameter pipeline is the aorta in the pipeline system. PE steel mesh skeleton pipe is a new type of environmental protection pipe with high strength, light weight, wear resistance and impact resistance. Pressure resistant and corrosion resistant large-diameter steel mesh skeleton pipe is one of the main research directions.
PE steel wire mesh skeleton pipe has great development potential and has been recognized. PE steel wire mesh skeleton pipe is a new type of composite structure wall pipe with integral pipe wall, which uses high-strength steel wire and polyethylene plastic as raw materials, winding high-strength steel wire as core layer, and high-density polyethylene plastic as inner and outer layers. The PE steel wire mesh skeleton is added with steel wire reinforcement mesh, which not only greatly improves the pressure resistance of the pipe compared with PE solid wall pipe, but also retains the excellent corrosion resistance and scale free characteristics of PE stone wall pipe.
The steel wire mesh skeleton tube is rigid and has good impact resistance. It is also moderately flexible and combines rigidity and flexibility. The elastic modulus of steel is about 200 times that of polyethylene, and the modulus effect of wire mesh skeleton pipe is not inferior to that of any wire mesh skeleton pipe on the market. The steel mesh skeleton itself is a flexible structure, which makes the steel mesh skeleton tube flexible in the axial direction.
Moreover, the inner wall of PE steel mesh skeleton pipe is very smooth. This can reduce the friction force of the pipe to a very small level, and also ensure the working efficiency of the steel mesh skeleton pipe.
Generally, under normal use conditions, the service life of the steel mesh skeleton pipe is generally maintained at about 50 years. The steel mesh skeleton pipe composite pipe effectively improves the economic applicability of the pipe material. The water delivery volume is about 30% more than the traditional pipe material. The steel mesh skeleton pipe has always maintained a strong demand for the market.
