Steel mesh skeleton PE pipe, preferred pipe for fire water supply engineering

Core requirements for pipes in fire water supply projects

As an emergency support facility, the fire water supply system has strict requirements on the pressure-bearing capacity, corrosion resistance and water transportation stability of the pipe. Long-term use of traditional galvanized steel pipes is prone to rust and fouling on the inner wall, which will not only reduce the water transportation efficiency, but also affect the fire water output timeliness in severe cases. The cost of later operation and maintenance anti-corrosion is relatively high. Many projects are looking for alternative pipes with stronger adaptability.

Performance Adaptation Advantages of Steel Mesh Skeleton PE Pipe

Steel mesh skeleton PE pipe is made of high-strength steel wire winding mesh as a reinforced skeleton, and the inner and outer layers are made of high-density polyethylene. Compared with ordinary PE pipes, the pressure-bearing capacity enhancement is more than 40%, which can meet the pressure requirements of most fire-fighting water supply projects. Its temperature resistance range is wider, long-term operation is not prone to pipe deformation problems, and it has excellent corrosion resistance. It is not affected by soil pH and humid environment when buried in the ground, and the service life can reach more than 50 years. The smoothness of the inner wall of the pipe far exceeds that of the metal pipe, and the long-term water transportation will not scale, which can stably maintain the water transportation efficiency and ensure that the fire water outlet flow meets the design requirements.

Scene adaptation of construction and operation and maintenance

The weight of the steel mesh skeleton PE pipe is only 1/7 of that of the same specification steel pipe. There is no need for large lifting equipment for transportation and installation, which can greatly shorten the construction period. The interface adopts the electric melt connection process. The strength of the connection is higher than the pipe itself, and there will be no leakage and disconnection problems. It is suitable for various laying scenarios such as burial and overhead. There is no need for regular anti-corrosion and rust treatment in the later operation and maintenance. The operation and maintenance cost is only about 10% of the metal pipe. It is suitable for various fire water supply scenarios such as municipal fire protection pipe networks, industrial parks, and residential quarters.

Precautions for fire pipe selection

When selecting the type, the product corresponding to the nominal pressure level should be selected according to the engineering design pressure. Before construction, the appearance of the pipe should be checked for no damage or cracks. The hot-melt connection should be strictly implemented in accordance with the operating specifications. After the laying is completed, the water pressure test should be done according to the requirements of the fire protection project. After the acceptance is qualified, it can be put into use.
