The Technological Differences Between High-frequency Straight Seam Steel Pipes And Straight Seam Ste

Straight Seam Steel Pipe Refers To A Welded Steel Pipe With Only One Weld Seam In The Longitudinal Direction Of The Pipe Body. GB/9711.1 Stipulates That Straight Seam Steel Pipes Can Have Two Straight Welds With A Diameter Greater Than 914.4 And A Weld Angle Of 180 Degrees. The Welding Quality Requirements Are That Straight Seam Steel Pipes With The Same Weld Seam Have The Same Technical Parameters. According To The Production Process, It Is Divided Into: ERW High-frequency Straight Seam Steel Pipe, American Straight Seam Steel Pipe, And Rolled Straight Seam Steel Pipe. Straight Seam Steel Pipe Is A General Term For Production Process Products Such As High-frequency Straight Seam, Buried Arc Straight Seam, Electric Welding Straight Seam, And Pipeline Straight Seam.

The High-frequency Straight Seam Steel Pipe Adopts The Skin Effect Of High-frequency Current, Which Generates High Temperature At Both Ends Of The Steel Plate In A Short Period Of Time, And The External Force Is Compressed And Fused, Truly Achieving Seamless Base Metal Docking. ERW High-frequency Straight Seam Steel Pipes Are Made Of Hot-rolled Coils As Raw Materials.

The Wall Thickness Can Be Controlled At Around ± 0.2mm. The Two Ends Of The Steel Pipe Have The Advantages Of JCOE APl Standard Or GB/T9711.1 Standard, Trimming Angle And Delivery Length. In Recent Years, Various Natural Gas Pipeline Projects And Gas Companies Have Widely Adopted ERW Steel Pipes As The Main Steel Pipes For Urban Pipelines. At Present, The Proportion Of Steel Pipes Used For ERW High-frequency Straight Seam Steel Pipes In The World Accounts For 60%

Straight Seam Steel Pipes Are Commonly Referred To As JCOE Double-sided Submerged Arc Straight Seam Steel Pipes. Adopting JCOE Cold Forming Process, Welding Wire Is Used For The Weld Seam, And Particle Flux Is Used For Submerged Arc Welding. Therefore, It Is Named As A Buried Arc Straight Seam Steel Pipe. The Main Production Process Of Submerged Arc Welded Straight Seam Steel Pipes Is Flexible, And Can Produce Any Size And Wall Thickness Between 325mm-1420mm. It Greatly Meets The Use Of Steel Pipe Size Standards In Various Countries Around The World, And High-frequency Straight Seam Steel Pipes Are Usually Used To Produce Universal Specifications.
