Some Common Knowledge and Industry Standards for Spirally Submerged Arc Welding

  The raw materials of spiral steel pipe are strip coil, welding wire and flux. Strict physical and chemical testing is required before production. The steel head and tail are butt jointed, and the single wire or double wire submerged arc welding is used. After the steel pipe is rolled into a st ...

Identification Method of Fake and Inferior Seamless Steel Pipe

The structure is folded with a seamless steel pipe which is a variety of fold lines formed on the surface of the steel pipe, and such defects often extend throughout the longitudinal direction of the product. The reason for the folding is that the inferior manufacturer pursues high efficiency, th ...

Detection of Heterogeneous Atoms in Thermally Expanded Steel Tubes

Detection of Heterogeneous Atoms in Thermally Expanded Steel Tubes Due to the roll strengthening mechanism, increasing the strength of the metal allows the metal to form a solid alloy with another metal (or non-metal). Solid solution alloys or alloys based on solid solution (such as carbon steel ...

Sizing Technology Of Steel Pipe Plant

When the steel pipe is sized by the micro-tension reducer of the steel pipe plant, the steel pipe wall is unevenly thickened due to the lateral deformation of the metal (flowing in the radial direction), and the inner hole of the cross-section is "six square", commonly known as "inside" Six parties. ...

Stainless Steel Seamless Pipe Is Different From Seamed Tube

The stainless steel seamless pipe is manufactured by punching a hole in a stainless steel billet at a temperature of 2,200 °F. At this high temperature, the tool steel is softened and spirally formed from the hole by punching and drawing. In this way, the wall thickness of the pipe is uneven and t ...
