The production process of straight seam steel pipe is divided into high frequency welding process and submerged arc welding process.Seamless steel pipes are a production process in which round steel is perforated and formed in one go.

ERW pipeline assessment includes non-destructive and destructive testing.

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.
