Several common uses of seamless steel pipes

Seamless steel pipe is a long strip of steel with a hollow cross-section and no seams around it. Below, I will take you to understand the uses of several common seamless steel pipes:

Cold rolled seamless shaped steel pipes (GB/T3094-1999): mainly used for manufacturing general structural components.

Seamless steel pipes for conveying fluids (GB/T8163-1999): mainly used for conveying pipelines. For example: central air conditioning, cold storage, gas, fire engineering, etc.

Precision inner diameter seamless steel pipes for hydraulic and pneumatic cylinder barrels (GB/T8713-1988): mainly used for manufacturing hydraulic and pneumatic cylinder barrels and other pipe fittings with high requirements for internal and external surface roughness and precise internal and external dimensions. For example: jacks, shock absorbers, motor casings, cylinders, injection molding machinery, etc.

Seamless steel pipes for structural purposes (GB/T8162-1999): mainly used for general structures and mechanical structures.

Seamless steel pipes for low and medium pressure boilers (GB3087-1999): mainly suitable for superheated steam pipes, boiling water pipes, and other pressure heated pipe fittings in low and medium pressure boilers.

Bearing steel pipe (YB/Z12-77): mainly used for manufacturing rolling bearing rings.

Cold drawn precision welded pipe: mainly used for manufacturing bicycle pipe materials.

Hydraulic prop pipe: mainly used for manufacturing hydraulic props, lifting props, and hydraulic cylinder inner cylinders for coal mines.

Carbon steel seamless steel pipes for ships (GB/T5312-1999): mainly used for manufacturing Class 1 and Class 2 pressure pipes for ships.
