(PGJ) - Evaluation of a facility, based in the north of Thailand, found that a huge pipeline () carrying high-pressure water for injection into oil wells was suffering from thin wall defects. The pipeline in question was made out of 39-foot (12-meter) pipe lengths that had been welded together. Upon inspection, it was discovered that the 2,000 psi of water and the weld filler material in use had resulted in internal corrosion defects at every circumferential weld joint. This caused the deterioration of pipe wall thickness, risking high-pressure leaks. The customer had used Belzona previously and was impressed by the cold bonding process demonstrated on a defective joint, which led to an agreement to undertake the repair of the entire pipeline, requiring an estimated 11,000-15,430 pounds (5,000-7,000-kg) of Belzona 1111 metal. Due to the scale of the project, repair would be completed in three stages. More than 1,000 joints were repaired in 2020, and the remaining defects were addressed in November and December 2022. The joints repaired in the first stage performance went well when placed in service.
