How to control the defects within the surface of the seamless steel pipe?

1, De-oxidizer Oxide requirements in the mandrel pre-piercing in a molten state. Its strength and other strict requirements. (1) In addition to the oxidizer powder particle size is generally required to be about 16 mesh. (2) The content of sodium stearate in the de-oxidizing agent should be more than 12% in order to enable it to burn fully in the inner cavity of the capillary. (3) According to the inner surface area of the capillary to determine the spray volume of de-oxidizing agent, generally 1.5-2.0g/dm2, different diameters, lengths of the capillary blowing de-oxidizing dose is different.
  • What are the notes for the storage of seamless steel pipe?

    In the process of anti-corrosion construction of oil and gas pipeline, the surface treatment of seamless steel pipe is one of the key factors to determine the service life of pipeline anticorrosion, which is the premise of whether the anticorrosion layer and the seamless steel pipe can be firmly combined. By the research of professional organizations, the life of the anticorrosion layer depends on the type of coating, coating quality and construction environment and other factors, the surface treatment of seamless steel pipe on the life of the anticorrosion layer accounts for about 50% of the impact, therefore, should be in strict accordance with the specification of the anticorrosion layer on the surface of the seamless steel pipe, and constantly improve the surface treatment of the seamless steel pipe.
