- Model PSX - Repair System

From

0

The STOP IT PSX Repair System derives its high pressure capabilities from the use of a field-mixed, two-part epoxy primary sealant and a fiberglass/urethane composite overwrap. STOP IT PSX can be installed by one person with no special tools or hot work, and provides for the completion of in-field repairs and return to service in a total of 4 hours.

Following the cleaning and preparation of the surface, repairs involve the application of a thin film of epoxy sealant from the supplied cartridge gun. Precise mixing is accomplished with the use of a static mixer that is attached to the gun. Once hardened (approximately 1 hr), the sealant is overwrapped with a fi berglass tape impregnated with water-activated polyurethane resins. Systems may be returned to service at pressures up to 2500 psi as soon as 4 hours following the application of the epoxy.

Stop It PSX can be used almost anywhere – including underwater and in chemical and military facilities – to repair chemical, steam, process and water lines.

STOP IT PSX Is Ideally Suited For:

  • Routine and emergency high pressure leak repair
  • Sealing joints
  • Rebuilding thinning wall in high pressure piping
  • Repairs in hard to reach areas
  • Underwater repairs
  • Large scale defects (Voids up to 1.0” od repaired to 500 psi)
