Many mine pipeline projects have some problems, such as insufficient water pressure, pipe explosion and leakage, rapid aging of pipe network, etc., which are not essentially pipe quality problems, but caused by mismatched design parameters in the early stage, chaotic application of standards, and inadequate site construction details. Especially in South Africa mining area, the terrain difference is large, the temperature difference between day and night is obvious, and the field conditions are harsh, so the requirements for the design specification, pressure bearing grade and laying standard of South Africa mining pipeline are far more stringent...
