EN LSAW Steel Pipe

LSAW steel Pipe,Longitudinal-seam Submerge arc welding steel pipe,DSAW steel pipe.

The material of LSAW steel pipe is unit middle or heavy thickness sheet,coiled in the molding or forming machine, welded by double submerged arc welding and expand the diameter.the specification scope is wide,and have good toughness,ductility,uniformity,compactness.Advantage of LSAW steel pipe the difference with SSAW steel pipe: Diameter large,heavy wall thickness,anti-high pressure,anti-low temperature and corrosion. Our Allland could supply EN standard LSAW pipes, such as EN 10219, EN10217, EN10224, EN10219 Cold formed welded structural hollow sections of non-alloy and fine grain steels.

Part 2: Tolerances,dimensions and sectional properties, specifies tolerances for cold formed welded circular,square and rectangular structural hollow sections,manufactured in wall thickness up to 40mm. Circular outside diameters up to 2500mm, The formulae for calculating sectional properties of sections manufactured to the dimensional tolerances of this standard,to be used for the purposes of structural design,are given in Annex B. Dimensions and sectional properties for a limited range of sizes are given in Annex C. Technical delivery conditions are specified in EN10219-1.
