Our Method Of Inspection And Decision For Repairs

Prior To Repair

Before we begin with the vessel repair and refurbishment service, we conduct a thorough inspection and revision of the product, including:

Operating conditions, inspection history, material of construction of the pressure vessel
Reasons for failure
Location of the damaged area by visual inspection and evaluation by non destructive testing (NDT)
Re-evaluate the need for repairs so as to not cost the client for worthless damages.
Repair methods ( for pressure retaining parts)
Preparation of a repair procedure

The repairer, under close supervision and surveillance of the inspector, executes actual repairs. The written and qualified procedures are strictly followed. In case the impact testing is specified, the welding parameters are also monitored and ensured to be within the range at which the procedure is qualified.
Specified NDE before welding repairs and after welding repairs are carried out and are approved by the inspector.
After repairs the inspection record and the history of equipment, giving details of repairs, is updated and a next inspection schedule is recommended to the owner/user.

Once the decision of welding repairs is taken then it is necessary to document the repair procedure giving details of NDT test necessary, pre heat and PWHT (as required), welding sequence, monitoring the welding parameters, pressure test requirements etc. We also prepare the inspection reports and follow up inspection at a predefined inspection interval.
