The steel mesh skeleton plastic composite pipe is a new type of environmental protection pipe, also known as "steel mesh pipe, steel mesh skeleton plastic composite pipe, SRTP pipe, STSCP pipe, SPE pipe". It is not only suitable for municipal administration, building water supply and drainage, fire protection, gas transmission, but also widely used in chemical, petroleum, pharmaceutical and other industries. It not only retains the excellent pressure resistance of steel pipe, but also retains the good sanitary performance of plastic pipe, which is characterized by convenient laying, reliable connection and long service life.
With the same flow, the fluid resistance is small, the pipe wall is lubricated, the roughness of the inner surface can reach 0.8 μ m, and the roughness of the wall and the glass fiber reinforced plastic pipe is 30~50 μ m, which is extremely coarse. With the formation of rust with the steel pipe, the friction coefficient is large. With the increase of the service life, the maintenance and operation costs will increase. Check and control more light, reduce the resistance, and save energy.
2. Rigidity and flexibility: the rigidity, impact resistance and size invariability of the reinforced steel mesh skeleton plastic composite pipe are more than any pure plastic composite pipe. Moreover, because the network steel skeleton itself is a flexible structure, the axial direction of the composite pipe is flexible. Therefore, the pipeline has the characteristics of rigidity and flexibility, which makes the loading, transportation and equipment more flexible and operable. The embedded laying device can effectively accept the impact caused by uneven settlement, slip and vehicle impact load. In addition, due to the good flexibility of the pipeline, the pipeline itself does not have high requirements on the bottom of the pipe trench, so it can be bent properly to coordinate with the placement of rugged terrain, which is more conducive to construction under adverse conditions. When the medium temperature changes little, the device generally does not need to be compensated, thus reducing the data volume and device cost.
3. Convenient maintenance: the connection of the steel mesh skeleton plastic composite pipe is made by electrofusion. After the pipes and pipe fittings are assembled with resistance wires, the pipe fittings are electrically heated according to the necessary welding parameters to complete the interface connection. After joint connection, the pipes and pipe fittings are firmly connected, and the welding equipment to ensure the welding quality controls the welding parameters. The influencing factors and salary factors of the situation are very small, the equipment is convenient, fast, and the construction efficiency is high; There is no open fire operation during pipe connection, and the construction safety factor of key fire prevention parts is high. The structure is simple and the quality is easy to control.
