Your choice in service providers is critical to success. Once the vessel passes all tests, the repair tag will be welded to the vessel and it is ready to be placed back into service. This test must be witnessed by an Authorized Inspector in order to meet ASME specifications. If the equipment requires electropolish and passivation, a qualified surfacing finishing technician ensures both processes meet the required standard to complete the repairs and prepare the vessel for testing.įinally, once the repairs, modifications and polishing are complete, test the equipment per the specifications from the U-1 Report. Once any replacement components have been welded into their required locations, polish the surface surrounding the repair to the finish specified in the original drawings.
Next, remove the broken unit or make the necessary modifications. Be sure that your replacement parts include a material test report (MTR) and that these reports are reviewed prior to installation. Once an engineer completes any follow-up calculations, any replacement parts must also be tested prior to installation, in order to ensure the replacement parts are also up to standard. These essential elements include the necessary calculations that ensure its pressure rating won’t be compromised by the modification or repair. When you have a pressure rated vessel that requires modification – or in need of repair that includes welding – gathering the right information is the most important factor in getting the project moving correctly.įirst, get the build drawings and the vessel’s U-1 Report.
But, how can you be sure your vessel meets those standards when the repair is complete? Ensuring an ASME Code Weld repair is completed in accordance with ASME Division I Section VIII Rules for Construction of Pressure Vessels requires several steps. Your pressure rated vessel needs to be repaired to the required standards to ensure safe operation.
