The Difference Between Submerged Arc And High Frequency Straight Seam Steel Pipe Welding Technology

- Jun 30, 2017 -

Production includes: submerged arc steel pipe production diameter 325mm to 1420mm, the production wall thickness from 7.5mm to 80mm. High frequency steel pipe production diameter 15mm to 660mm, production wall thickness from 0. To 1mm. Production of materials: submerged arc steel pipe can produce any material straight seam submerged arc welded straight seam steel pipe. and the highest executable 9711, API straight seam submerged ARC steel pipe ASWL standard. High-frequency steel pipe can produce the highest quality pipeline. such as L245 to L485, X42 to X80, can perform 9711, API straight seam pipeline pipe standard. Use of industry: submerged arc steel pipe can be used for large-diameter oil and gas pipelines, steel pipe piling, steel structure, submarine steel pipe. High-frequency steel pipe can be used for grid structure tube, small-caliber fluid steel pipe, wire pipe, light structure foundation, bottom pressure fluid steel pipe. Appearance main difference: High frequency straight seam steel pipe and submerged arc straight seam pipe of the tube of the most obvious difference is the appearance, high-frequency straight seam steel pipe outsourcing smoothing, no high weld, the tube is green gray. The submerged arc straight seam steel pipeline first has the microscopic strip indentation, the plate epidermis oxide has the slight shedding mark.
