How to clean the straight seam steel pipe?
How to clean the straight seam steel pipe? (1) We can use solvent or emulsion to clean the surface of the steel pipe. This method is very effective for the presence of oil and grease or dust and other organic substances on the surface of the steel pipe. (2) For the case of rust on the surface of ...Read more -
Method for improving rust resistance of large-caliber steel pipe
1.When sand blasting or manual mechanical derusting is used, the metal scale on the surface of the large-diameter steel pipe is directly exposed to the air due to the peeling of the oxide scale from the large-diameter steel pipe. If a primer is not painted in time, the surface of the large-diamet...Read more -

Temperature problems in the production of straight seam steel pipes
In the process of producing straight seam steel pipes, the temperature must be strictly controlled, so as to ensure the reliability of welding. If the temperature is too low, it may cause that the welding position cannot reach the temperature required for welding. In the case where most of the me...Read more
