On-site flange face and nozzle insert repair
Heat cycling, gasket-witness machining and dropped tools deform flange faces and corrode nozzle sleeves, so the line leaks and stays out of service.
The need for on-site flange face and nozzle insert repair
BHI Coatings performs on-site flange face and nozzle insert repair across Alvin and the Texas Gulf Coast. A flange face takes abuse from every direction. Heat cycling, gasket-witness machining, a dropped tool, and corrosion working into the nozzle sleeve. Once the face is scored or deformed the joint will not seal, so the line weeps or stays blanked off, and cutting the spool out for shop re-machining buys you a long line break and a welding permit.
How BHI Coatings does on-site flange face and nozzle insert repair
We reform the flange face in place, casting it against the mating flange with a release agent so the cured surface mirrors its partner exactly. The crew prepares the corroded steel, rebuilds the face with machinable composites such as Belzona 1111 and 1121, and uses a release film like Belzona 9411 to take the impression. No hot work, and the spool never leaves the line.
Typically applied with Belzona 1111, Belzona 1121, Belzona 9411, matched to the service conditions.
The flange seats and seals against the very face it has to mate with. Nothing is cut out, no welding permit is pulled, and the spool never makes a trip to a shop.
