Structural seamless steel pipes are used for the processing and use of mechanical structures. The representative materials of structural seamless steel pipes are carbon steel 20, 45#, alloy steel Q345, 20Cr, 40Cr, 20CrMo, 30-35CrMo, 42CrMo, etc.
The application of fluid seamless steel pipe is for fluid transportation. In terms of manufacturing, domestic steel pipes are made of 10#, 20# carbon steel hot-rolled pipes or cold-drawn pipes.
The difference between fluid seamless pipe and structural seamless pipe is that the fluid seamless pipe needs to do hydraulic experiments one by one or do ultrasonic, eddy current, and magnetic flux leakage flaw detection. Therefore, in the standard selection of pressure pipeline steel pipes, it is more suitable to use fluid seamless steel pipes.
