Our LSAW steel pipes are good at producing the heavy wall thickness and large diameter LSAW /DSAW pipes,it is our advantage of LSAW technology,other pipes could not reach this point.

The large diameter LSAW(SAWL,DSAW Longitudinal-seam Submerge arc welding steel pipe ) ,for its advantage,it is usually used for construction.

Large-diameter, thick-walled, high-grade steel. Common pipe diameter Φ406mm-1600nmi, pipe wall thickness is 20nm-50mm, made of steel pipe Q345B, C, D ~ Q690E. Steel varieties can have these parameters conditions towel with JCOE way to produce double-sided submerged arc Longitudinal product has a unique advantage, it is the dominant product, other steel varieties (such as seamless steel pipe, spiral steel pipe, high frequency welded steel pipe) in the steel structure as an auxiliary product. Special diameter pipe wall thickness, the use of rolled steel, large CNC horizontal hydraulic three roller coiling machine manufacturing, diameter up Φ1600mm-3000nun, wall thickness of up to 90mm-110mm, the material yield strength of up to 245MPa-345MPa. 3.2 steel structure applications and market needs 3.2.1 high-rise building steel structure tallest tower in Asia, high-rise building steel column Guangzhou New TV Tower (see Figure 1). Guangzhou New TV Tower on the ground 37 floors, 3 basements height of 610m (tower 454m, antenna masts 156m).
