Longitudinal LSAW PIPE Large Diameter steel pipe EN 10219 EN10210-S355JO LSAW Steel Pipe



 UOE Produce Processes

 There are several technique to produce LSAW steel pipe,such as UOE,JCOE,RBEand so on.And the main  method is UOEtechnique.

 UOE is a method used for production of longitudinally welded large diameter pipes. Longitudinal edges of  steel plates are first beveled using carbide milling equipment. Beveled plates are then formed into a U  shape using a U-press and subsequently into an O shape using an O-press.Longitudinal edges of the  plates are then tack welded followed by internal and external welds.Pipes manufactured by this process  are subjected to expanding operation in order to relieve internal stresses and obtain a perfect dimensional  tolerance.


 1)Payment terms: When the customer passes the evaluation of our risk control department, we can sell  on credit.
 2)The customers’ own inspection or third party’s inspection is warmly welcomed before shipment
 3)We accept 100% L/C payment + third party inspection
 4)With 18 years’ history in the steel pipe industry, we own rich experience in steel pipes, whether it is  seamless steel pipe, welded steel pipe, rectangular pipe or pipes with special section or the pipes’ anti-  corrosion technology. We can provide you specialized suggestions and satisfying goods’ quality with  competitive price. Besides, with rich exporting experience, our professional exporting team will always  offer you the quick response and best service.
