Sometimes, stainless steel seamless pipes used in factories may have grease on them. These greases may affect the sealing performance of seamless pipes. Therefore, many factories will choose different methods for degreasing.

Although there are some shortcomings in using seamless pipes for heating, by choosing the appropriate material, manufacturer, installation method, and doing maintenance work, these defects can be eliminated to the greatest extent and allowed to operate normally.

The openings of seamless steel pipes must not only meet quality requirements, but also meet relevant specifications and standards.

The acceptance of seamless steel pipes should follow corresponding specifications and standards, mainly including appearance inspection, physical performance testing and chemical composition testing.

Bright steel pipe is a refined steel pipe that is cold drawn or cold rolled. Bright seamless pipes must undergo non-oxidation bright heat treatment (NBK state), non-destructive testing, the inner wall of the steel pipe is brushed with special equipment and high-pressure flushing, anti-rust oil is applied to the steel pipe for anti-rust treatment, and both ends are capped for dust-proof treatment.

Large-diameter spiral steel pipe is a general term, generally referring to spiral steel pipes (SSAW steel pipe) with a diameter greater than 1 meter. Spiral steel pipe is a welded steel pipe made of steel strips that are bent and then welded. Steel pipes need to undergo hydraulic pressure, bending, flattening and other experiments, and have certain requirements for surface quality. The delivery length is usually 12 meters, and delivery to fixed length is often required.
