INDUSTRIAL BOILER D-PATCH REPAIR

D-Patch Repairs are an extremely common repair on steam package boilers. NDT testing is carried out every five years, a process which looks for defects within the structure of the boiler. If defects are discovered, it’s our job to remove the defect.

Our engineers have carried out numerous d-patch repairs on various types of steam boilers. We provide the full documentation required, including welders qualifications, material certification, method statements and risk assessments.

CASE STUDY: D-PATCH REPAIR
CLIENT: PET FOOD MANUFACTURER Case study
JOB: D-PATCH REPAIR TO ACCESS RING OF WELLMAN –ROBEY STEAM BOILER
SCOPE OF WORK
During a scheduled service and NDT inspection a crack was discovered in the rear access ring of the boiler. On receipt of the location of the crack from the NDT surveyor, we quickly formulated a quotation and method statement for the work. Once approved, the material for the repair was obtained and rolled to the correct dimensions. Our foreman boilermaker arrived on site with all the equipment to carry out the repair; cut the defective section of plate out; ground a prep on the new patch and access ring, and tacked the new plate into place. The “tack-up” was approved by the insurance surveyor, and the patch was fully welded up in position. Finally the new weld was re-tested and approved, a hydraulic test applied for the insurance surveyor was carried out, and the boiler boxed back up and returned to service.
