Structural seamless steel pipes are good for the processing and use of general structures and mechanical structures. The materials of structural seamless steel pipes are diverse. The materials are carbon steel 20, 45# steel, alloy steel Q345, 20Cr, 40Cr , 20CrMo, 30-35CrMo, 42CrMo, etc.

The fluid seamless steel pipes is used to transport fluids. The domestic pipes are mainly made of 10#, 20# carbon steel hot-rolled pipes or cold-drawn pipes.

The difference between fluid seamless pipes and structural seamless pipes is that fluid seamless pipes need to be subjected to hydraulic tests one by one, or ultrasonic, eddy current, and magnetic flux leakage testing. In the standard selection of pressure pipeline steel pipes, fluid seamless steel pipes are more suitable.
