The quality standards for seamless steel pipe

Seamless ( CARBON SMLS) Steel Pipe is made from a solid round steel ‘billet’ which is heated and pushed or pulled over a form until the steel is shaped into a hollow tube. The seamless pipe is then finished to dimensional and wall thickness specifications in sizes from 1/8 inch to 34 inch OD.
  • The heat treatment of carbon steel pipe

    Carbon steel pipe as a product must have a certain performance to meet the needs of the usage conditions. Improving the performance of the steel is two ways, First, adjusting the chemical composition of the steel alloying; the other is the heat treatment, heat treatment and shaping deformation combination of approaches. In the field of modern industrial technology, heat treatment to improve the performance of the steel still occupy a dominant position.
  • The development of thermal contraction steel pipe production technology

    Heat-shrinkable diameter steel pipe production technology development began in the early nineteenth century oil development in the rise of the bicycle manufacturing industry, during the two world wars, ships, boilers, aircraft manufacturing after World War II thermal power boiler manufacturing, chemical industry development and oil and gas drilling and transportation, a strong impetus to the development of the steel industry in the varieties, yield and quality.
  • Submerged Arc Welding Straight Seam Steel Pipe

    Straight seam submerged arc welded steel pipe used for the submerged arc welding process technology, the use of filler welding, submerged arc flux particle protection.
