The steel skeleton polyethylene composite pipe refers to a new type of composite pipe, in which high strength steel wire coated with hot melt adhesive is cross wound on the polyethylene core pipe, and a layer of high strength hot melt adhesive is extruded to form a reinforcement layer, and the outer layer is covered with a polyethylene protective sleeve. The composite reinforcement technology of steel makes the reinforcement layer and the inner and outer polyethylene layers form a solid whole, and not only the metal skeleton is effectively and reliably protected without gaps.
The reinforcing layer and the inner and outer pipe walls have also been integrated with each other without the joint gap interface, which eliminates the erosion and damage that may be caused by the pressure or corrosive medium in the pipe to the pipe. It is a new high-tech product. Performance characteristics: high pressure resistance grade: compared with other solid wall pipes, the pressure is high (10-35 tMPa), corrosion resistance: it has strong resistance to acid, alkali, salt and other chemical media.
Good temperature resistance: when the temperature rise of the conveying medium is the same, the reduction of strength is more than twice that of polyethylene pipe. Low flow resistance: the internal surface roughness of the steel wire mesh composite pipe is only one twentieth of that of the steel pipe, and there is no scaling, no wax, and no decline in transmission capacity due to corrosion, scaling, etc. Therefore, the steel wire mesh composite pipe has high fluid transmission capacity and remarkable energy-saving effect.
Light weight: under the same pressure level, it is lighter than the solid wall pipe of the same specification, reducing the comprehensive cost of the project. Non toxicity: good sanitation, solved the secondary pollution problem of drinking water, and complied with the provisions of GB/T17219-1998 safety evaluation. Reliable connection: the pipeline is connected by electrothermal melting, which is convenient for construction, simple and reliable welding process, and can achieve no leakage in the whole pipeline system.
