Piping leaks are typically fixed with a piping enclosure

Piping spools vary with a wide range of size and complexity, each presenting their own unique tendency to leak. Piping leaks are caused from many methods, a few are suggested
below

  • Erosion and Corrosion
  • Failed welds
  • Cavitation
  • Chemical attack
  • Pipe vibrations
  • Over pressurization caused by plant upsets

Our engineers, working closely with your shop and field personnel, can develop industry leading solutions.

Common sealing techniques and designs

Their are three primary techniques for sealing piping leaks:

  1. Void fill
  2. Peripheral seal / seam seal
  3. Weld on fitting

Void Fill Technique

The void fill process involves injecting the entire cavity of the enclosure with sealant to stop the leakage, and reinforce the outside of the pipe. While these are typically the simplest designs, they cannot be used on leaks where a crack is present, or where the pipe wall thickness is sufficiently thin.

Peripheral Seal / Seam Seal Technique

Peripheral seal designs incorporate a seam seal through the split line of the box, and through the bores onto the existing pipe. The design process is more involved, but resulting design will seal without sealant contacting the piping defect.
