Straight Seam Submerged Arc Welding Pipe: JCOE Steel Pipe forming material."J-C-O-E" Pre-Welding, Forming, Cold Expanding after Welding and other processes.Using a single medium thick plate as raw material, the steel plate is pressed (rolled) into a blank in the mold or forming machine, and the pipe is formed by double-sided submerged arc welding and expanding. JCOE steel pipe molding, one weld, submerged arc welding process, specifications range from 325mm - 1420mm. When the diameter of the Direct-Seam Submerged Arc Welding Pipe is greater than 914.4mm, the Standard Stipulates that the Steel Pipe is allowed to have two Straight Welds.


Technical Parameters:

  • Wall thickness: API 5L X80 Steel Grade can reach 6.4-23.8mm (0.252-0.94 in)
  • Wall thickness: API 5L X70 Steel Grade can reach 6.4-26.4mm (0.252-1.04in). The wall thickness can be increased to varying degrees when the material is reduced.
  • Product standards: ISO3183-3, API Spec 5L, etc
  • Straight Seam Submerged Arc Welded Steel Pipe Diameter Range: Φ406.4-Φ1422.4mm
  • Length: Max Length 12.2m

Feature:

  • Steel Pipe has a longitudinal weld, and the inner and outer welds are welded by a Submerged Arc Welding
  • After the overall mechanical expansion treatment, the internal stress of the steel pipe is small and evenly distributed, which can effectively prevent stress corrosion cracking, and the dimensional accuracy is high, which is convenient for on-site welding construction
  • Pre-welding and then fine welding, stable welding, high weld quality
  • The weld is easy to achieve non-destructive testing in the production process and non-destructive testing review in the use process
  • Can produce small diameter, large wall thickness; Can also provide large diameter, large wall thickness
  • High pressure resistance, low temperature resistance and corrosion resistance

Mechanical properties:

  • The strength characteristics are high, and the yield strength and tensile strength indexes can meet the low temperature environment. The yield strength reaches a certain standard, can withstand the pressure and external load in the low temperature environment, prevent excessive deformation or rupture of the pipeline, and is suitable for the medium and low temperature fluid conveying system with high strength requirements.
  • Strength is satisfied to be able to have good toughness. When the steel pipe is subjected to impact, vibration or complex stress, the toughness can effectively absorb energy and avoid brittle fracture. Toughness is particularly important in piping systems

Application:

  • Petrochemical field: Widely used in the petroleum and chemical industry to transport a variety of low temperature oil, chemical raw materials and finished products. Medium temperature crude oil pipeline in refinery, low temperature chemical pipeline in chemical plant, etc. To meet the needs of fluid transportation in the chemical production process.
  • In the field of building and heating: for piping systems in building structures. The heating system provides heat by piping medium-temperature hot water
  • Ventilation and air conditioning systems of industrial buildings deliver low-temperature air or fluid to ensure the comfort of the internal environment
