Production base_Hebei Allland steel pipe manufacturing Co., Ltd.

Our company has introduced a complete set of advanced JCOE production equipment and testing equipment for submerged arc straight seam steel pipes, specialized in the production of thick wall large-diameter straight seam double-sided Submerged arc welding steel pipes(LSAW), with product specifications of φ 406mm- φ 1422mm, length 3m-12m, wall thickness 7mm-40mm, product standards: GB/T3091, GB/T9711 PSL1/PSL2, API 5L PSL1/PSL2, EN10219, etc., materials: Q235, Q345, L175-L555, X42-X80, S355J2, etc.

The double-sided submerged arc welded pipe is mainly rolled with hot rolled coils and medium thick plates. The double-sided submerged arc welded pipe adopts double-sided submerged arc welding machine technology, and its wall thickness is relatively thicker than the ordinary welded pipe. Compared to ordinary wall thickness welded pipes, the advantages are: high compressive strength, high impact strength, high performance, and long service life.

Over the years’ experience, we insist on the quality as the base, carried out strictly in accordance with the corresponding standards from the raw materials procurement, plate detection, and processing production to finished LSAW steel pipes inspection and storage.
