A Review Experimental Investigation on LSAW large

carbon steel pipe is a type of SAW pipe made of steel plates that were hot rolled by JCOE or UOE forming technology.JCOE technology represents the shaping and forming processes involved during manufacturing as well as the inner and outer welding and cold expansion carried out after welding.When compared to UOE LSAW steel pipes,LSAW pipe manufacturers in China can produce more sizes

Carbon Steel tube

It adopts JCOE steel tube forming,a weld seam and submerged arc welding process,and the specification ranges from 325mm to -1420mm.When the diameter of a straight submerged arc welded pipe is greater than 914.4,the standard stipulates that the steel pipe has two straight welds.SSAW Steel Pipe (Spiral Submerged- Arc Welded Carbon Steel Pipe)China LSAW JCOE Welded Steel Pipe Manufacturers and LSAW JCOE Welded Steel Pipe.Longitudinally Submerged Arc Welding is abreviated as LSAW.API 5L X70 LSAW JCOE Welded Steel Pipe is produced by using a single plate as a raw material,pressing (rolling) the steel plate into a tube blank in a mold or a molding machine,and using double-sided submerged arc welding and expanding the diameter.

Comparison of UOE and JCOE Pipe on Specification and

For JCOE,steel pipe forming is taken by bending machine step forming the bending pressure required to greatly reduce,so the power requirements of the unit greatly reduced.Therefore,in the case of the same unit pressure,JCOE can produce a greater range of wall thickness,and a set of molds can produce a variety of pipe diameter,pipe diameter can produce a greater range.Difference of JCOE welded steel pipe with high frequency Submerged arc straight seam steel pipe forming JCOE.Submerged arc straight seam steel pipe molding using letters of JCOE image into,is through successive stamping of the steel plate ten thousand tons of press,make steel plate gradually variant of the cold forming process.
