1. The long-term hydrostatic strength is stable. At 23 °/60 °/80 °, the creep resistance and failure strength of standard steel mesh skeleton pipes are far higher than those of pure plastic pipes and other traditional pipes of the same size.
2. Resistance to rapid cracking and environmental stress cracking. In PE steel wire mesh skeleton pipe products, due to the existence of annular steel wire mesh, the radial bearing capacity of the pipe is greatly improved, thus improving the fast cracking and environmental stress cracking performance of the plastic pipe wall of the composite pipe.
3. Impact resistance and dimensional stability. Due to the strengthening effect of steel wire mesh, the rigidity, impact resistance and dimensional stability of the composite pipe are superior to any plastic pipe. At the same time, the structural characteristics of the Wangzhuang steel skeleton itself make the composite pipe retain moderate flexibility in the axial direction. The pipe has the characteristics of rigid and flexible combination, which is not only convenient for transportation and installation, but also can effectively withstand the longitudinal load caused by soil settlement or sliding, surface vehicles, etc., and has good operation reliability.
4. Traceability. The traditional PE pipe has poor traceability, while the PE steel wire mesh skeleton can be traced with a magnetic metal detector due to the existence of the middle steel wire mesh, which can effectively track the pipeline path and reduce the construction difficulty.
5. The inner wall is smooth and has strong corrosion resistance. The smoothness of PE pipe is preserved on the PE steel wire mesh skeleton pipe, which means that the transportation efficiency is stronger. In addition, the corrosion resistance and chemical stability of PE pipe itself make it easier to transport brine for a longer time than traditional pipes, which is not conducive to damage.
The solubility and dissolution rate of salt minerals have high requirements for recovery. PE steel mesh skeleton pipe can better shorten the mining cycle and improve the recovery of salt mines.
In the process of well salt mining and transportation, collapse is sometimes unavoidable, and the toughness and crack resistance of wire mesh framework can ensure the safety of transportation.
