Hainan steel mesh skeleton pipe
1、 What is steel mesh skeleton composite pipe?
The steel mesh skeleton pipe is a short name for the steel mesh skeleton polyethylene composite pipe. It is a new type of improved pipe. It overcomes the shortcomings of steel pipe and plastic pipe, while maintaining the advantages of steel pipe and plastic pipe, it has higher pressure resistance and excellent flexibility.
2、 Production process of steel mesh skeleton composite pipe?
The steel wire mesh skeleton pipe is made by fusing the cross woven high strength steel wire after plastic as the skeleton and thermoplastic polyethylene as the skeleton. The steel wire winding mesh is used as the skeleton reinforcement of polyethylene plastic pipe, with high-density polyethylene (HDPE) as the core pipe matrix, and high-performance HDPE modified bonding resin is used to closely connect the steel wire skeleton with the inner and outer layers of high-density polyethylene.
3、 What are the characteristics of steel mesh skeleton composite pipe?
(1) Good creep resistance and high durable mechanical strength
As the plastic will creep under normal temperature and stress, and brittle fracture will occur under high persistent stress, the steel wire mesh skeleton can effectively restrain the creep of the plastic and greatly improve the durable strength of the plastic itself after compounding the steel wire mesh skeleton with the plastic.
(2) Rigidity, good impact resistance and dimensional stability
The reinforcement of the steel mesh skeleton makes the rigidity, impact resistance and dimensional stability of the steel mesh skeleton polyethylene composite pipe superior to any pure plastic pipe.
(3) Flexible structure, rigid and flexible
The mesh steel wire mesh framework itself is a flexible structure, so that the composite pipe has certain flexibility in the axial direction, and can effectively withstand the sudden impact load caused by settlement, slip, etc.
(4) Good corrosion resistance
The inner and outer polyethylene protective layers make the pipeline have better corrosion resistance than traditional metal pipelines, and can resist the corrosion of acid, alkali, salt and other chemical media.
(5) Good temperature resistance
Since about 2/3 of the strength of the steel mesh skeleton pipe is borne by the steel mesh skeleton, its strength decreases less with the increase of the service temperature than any pure plastic pipe. The experimental results show that the strength decreases below 5% for every 10 ℃ increase.
4、 How to connect the composite pipe with steel mesh framework?
The connection mode of the steel mesh skeleton pipe is electric fusion connection.
The electric melting pipe fittings with embedded resistance wires shall be closely contacted with the connection parts of pipes or pipe fittings for energization, and the connection parts shall be heated by the resistance wires to integrate them until the joints are cooled.
5、 What is the application field of steel mesh skeleton pipe?
(1) Underground drainage system, such as drainage ditch, rainwater drainage pipeline and underground passage;
(2) Road and bridge construction, which can be used for drainage and sewage system, can withstand the stress caused by vehicle and foundation settlement;
(3) Agriculture and irrigation and drainage system, which can be used for drainage system, irrigation pipeline and farmland drainage;
(4) Stormwater management for urban stormwater management systems, including stormwater drainage, stormwater collection and treatment;
(5) Environmental protection projects can be used for wastewater treatment, sewage discharge and other environmental protection facilities;
(6) Mining and mining industry, which can be used to transport ores, tailings and other materials;
(7) Food and chemical industry can be used to transport various liquids and chemicals.
