Medium Pressure Influence on Steel Pipe

The higher the pressure of the transmission medium, the thicker the thickness of the pipe, the pipe material requirements are generally higher. 

Medium pressure above 1.6MPa, the choice of seamless steel pipe or non-ferrous metal pipe. High pressure, such as ammonia, urea and methanol production, and some pipe media pressure up to 32MPa, the general choice of materials for the 20 steel or 15MnV high-pressure seamless steel pipe. In the vacuum equipment on the tube and the pressure is greater than 10MPa when the oxygen pipe, generally use brass and brass. 

Medium pressure below 1.6MPa, may consider the use of welded steel pipe, cast iron pipe or non-metallic pipe. But the cast iron pipe to withstand the pressure of the medium shall not be greater than 1.0MPa. Non-metallic pipe can withstand the medium pressure, and non-metallic materials, such as hard PVC pipe, the use of pressure is less than or equal to 1.6MPa; reinforced polypropylene pipe, the use of pressure less than or equal to 1.0MPa; ABS pipe, The use of pressure is less than or equal to 0.6MPa. In this case,
In this case,

For water pipes, when the water pressure is below 1.0MPa, the material is welded steel pipe; when the water pressure is greater than 2.5MPa, the general usethe carbon seamless steel pipe.
