What is the difference between the UOE&JCOE Pipe technologies for LSAW PIPES?
Analysis about Capability and Cost of UOE&JCOE Pipeline Key Words:
UOE welded pipe,JCOE welded pipe,LSAW steel pipe,DSAW steel pipe
UOE and JCOE are two advanced ways to produce large Diameter
Longitudinal submerged welded pipe.The form type is different between them.
From the internal&external line welding to the end of square cut, beveled ends,
cold expand the diameter,Hy test,UT test,X ray test,End test,length measure,weight
and marking,3PE,3PP Coating etc.two of third is completely the same.Now we study
the production process of UOE and JCOE,comparing the differences of production
ability(diameter,thickness and production efficiency etc.
1. Forming
UOE Two step: Form U, Form O
JCOE Six step: Form J, Take Out, Put in J type, Form C, Take Out, Backward bending
2.
Form | OD/mm | WT/mm | Yield to tensile | Production capacity(ton) | Residual stress | Accuracy | Efficiency |
UOE | 508-1422 | 6.4-25.4 | 0.89 | 400000 | low | high | high |
JCOE | 406-1626 | 6.4-60 | >0.9 | 200000 | high | low | low |
3. Production Cost
The cost of JCOE is lower than UOE
4. Flexible: JCOE is more Flexible more easily than UOE to change mold, for different pipe size production.
