Our steel pipes include four major types which are seamless pipe, ERW pipe, LSAW pipe, SSAW pipe. Seamless pipe supply scope is OD 10.3mm--965.2mm, wall thickness 1.0mm--60mm. The ERW pipes production range from OD 21.3mm--660mm, wall thickness 1.0mm--16mm. LSAW pipes can supply with OD 406mm--1524mm, wall thickness 6mm--50mm. SSAW pipes can produce maximum OD 3500mm, minimum OD 219.1mm, wall thickness 3.2--25.4mm.

Special boiler steel is derived from carbon structural steel. The chemical composition of boiler steel is basically the same as that of high-quality carbon structural steel of the same level, but the boiler steel mechanical property requirements are more strict, especially for impact toughness. And the aging sensitivity is required to be small. The boiler steel should be deoxidized and the non-metallic inclusions should be removed during smelting. The structure should be uniform. The grain size should be controlled in 3-7 grades. The defects such as interlayer, shrinkage, porosity and porosity should be minimized.SM520B carbon steel material

SM520B carbon steel material,In the second step of hot rolling process, different finished mills are used to roll billets or continuous casting billets into finished steel of proper shape and size. This production process is called finished product production, which is generally divided into two stages of rough rolling and finish rolling. In the roughing stage, a large amount of reduction (reduction per pass) is adopted to reduce the number of passes and improve the output; after roughing, the finishing stage is entered, and the finishing is carried out with a small amount of reduction to achieve a good surface and accurate size.SM520B carbon steel material
