Abstract:
Examination of External Weld Deposition Repair for Internal Wall Loss, Y. Y. Wang, EWI, March 1998.
Need: To Develop broadly applicable guidelines to safely repair internal wall loss of operating pipelines and components by external direct weld deposition
Result: Performed elastic-plastic finite element analysis of pipe sections with internal wall loss to determine remaining strength. Continued with finite element analysis of external direct deposition repairs of internal wall loss for straight and curved sections of pipe including elbows and tees. Compared predicted and actual burst pressures to validate results. Direct deposit welds of different sizes and geometry's were analyzed to determine extent of repair required to restore full strength.
Benefit: Pipe sections where full encirclement sleeves cannot be used can be repaired. This will reduce repair costs and avoid taking the pipeline out of service.
Price: $695.00
