FAQ

What is GOST 8734-75?

GOST 8734-75 is a Russian standard covering cold-deformed seamless steel pipes used for precision industrial applications.

What is 20# carbon steel?

20# carbon steel is a commonly used low-carbon steel grade offering good weldability, toughness, and machining performance.

Why are seamless steel pipes preferred?

Seamless steel pipes provide better pressure resistance and structural integrity because they do not contain welded seams.

What is hydrostatic testing for steel pipes?

Hydrostatic testing verifies the pipe’s pressure resistance and leak tightness by applying internal water pressure.

Can Haihao Group provide customized seamless steel pipes?

Yes. Haihao Group can manufacture seamless pipes according to customized sizes, material grades, testing requirements, and international standards.
