Belzona's polymeric repair and protection materials are suitable for extending the inservice life of assets in a multitude of industries, including equipment in the petrochemical industry which often functions in harsh environments. Belzona's products are suitable for both small-scale assets and extremely large projects, such as the recent restoration of a mammoth pipeline in a Thai petroleum production facility.

What was the problem?

The 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 12-meter pipe lengths that had been welded together. However, upon inspection it was found that the 2,000 psi water contents and the weld filler material used had resulted in internal corrosion defects at every circumferential weld joint. This caused the deterioration of pipe wall thickness, risking high-pressure leaks.
