Seamless steel tubes

Seamless steel tubes for general use are also supplied according to chemical composition and mechanical properties and hydrotesting. Seamless steel tubes subjected to fluid pressure should pass the hydraulic test. Special Liaocheng seamless steel pipe for boiler, geological exploration, bearing, acid resistance, etc.

Such as petroleum geological drilling tubes, petrochemical cracking tubes, boiler tubes, bearing tubes, automotive, tractor, aviation high-precision structural steel tubes.

Testing：

1．Observe the logo, specification, factory name and related information on the steel pipe.

2. Check the quality certificate provided by the seamless steel pipe manufacturer.

3．When buying seamless steel pipe, observe whether there are cracks, scars and other hard injuries on the surface of the steel pipe.

4. Observe whether the paint on the surface of the seamless steel pipe is even.

5. In order to avoid purchasing inferior products, try to purchase products from large and well-known brand companies.

Package of carbon steel seamless pipe
