Steel skeleton composite pipe steel mesh skeleton pipe is a new type of pipe with excellent performance, which has the advantages of strength, rigidity and impact resistance over pure plastic pipes, similar to the low linear coefficient and creep resistance of steel pipes. Compared with other solid wall pipes, the pressure bearing capacity of steel skeleton composite pipes is high, and the rigidity and impact resistance of steel skeleton composite pipes are good.
It is not afraid of collision during installation and use, and has good flexibility. It can be properly bent and arranged according to the terrain, saving pipe fittings, and its service life can reach more than 50 years. Under the same pressure level, it is lighter than the solid wall pipe of the same specification, which reduces the comprehensive cost of the project. For outdoor laying and seasonal operation, the average value of the daily average temperature of the operation period over the years shall be taken as the external ambient temperature.
In case of process requirements, the external ambient temperature shall be taken according to adverse conditions. The operating temperature of the hot water pipeline is low, and the heat loss is small, and the heat capacity of the water is large, so the temperature drop of the hot water is small, and generally it is not calculated according to the allowable temperature drop conditions. The steel skeleton composite pipe has excellent flexibility and is suitable for long-distance buried water supply and gas transmission pipeline systems.
The fittings used for the polyethylene composite pipe with steel mesh framework are polyethylene electrofusion fittings. During the connection, the outer plastic layer of the pipe and the inner plastic layer of the pipe are fused by the heating element inside the pipe, and the pipe and the pipe are connected together. It has strength, rigidity and impact resistance higher than ordinary pure plastic pipe, and is similar to low linear expansion coefficient and creep resistance of steel pipe.
