lsaw steel pipes vs ssaw steel pipes lsaw steel pipe mill

LSAW steel pipes are taking the steel plate as raw material,mold it by the molding machine,then do double-sided submerged arc welding.Through this process,the LSAW steel pipe will get excellent ductility,weld toughness,uniformity,plasticity,and great sealing.What is a SSAW pipe? - pipelinedubaiWhat is a SSAW pipe?.Spiral submerged arc welded steel pipe is a kind of metal pipe with spiral seam welded by submerged arc welding technology..SSAW pipe is made of hot rolled coiled steel by automatic submerged arc weld under normal atmospheric temperature.All the pipes are produced according to API Spec 5L,GB/T9711.1,GB/T9711.2,ASTM A252-89 standard.Welding method of steel pipe - bestartubesWhen small-diameter steel pipes are connected by butt welding,the internal cross-sectional area of the pipe may be reduced due to the dripping of the solder.Socket welding uses a fillet weld connection,so there is no problem of reducing the internal section of the pipe due to solder dripping,and the cost is low.
