Clamps and Enclosures

Colt’s patented interlocking pressure seal enclosures are stocked nationwide, enabling Colt to quickly build custom clamps with stock inventory. Our off-the-shelf inventory includes:

  • Flange clamps
  • Straight-pipe enclosures
  • 90° elbow-pipe enclosures
  • Strongbacks
  • Connectors
  • Injection valves
  • Wide range of sealants

If complex measurements or material specifications require a custom enclosure, our engineering and fabrication teams deliver the best customized solution. Drawings and calculations include all pertinent engineering design data with associated sources for customer review and approval prior to manufacturing and installation.

Wire Wraps

Colt’s wire wrapping techniques provide safe and cost-effective solutions for leaking gaskets on under-pressure bolted flanged connections. This can include:

  • Pipe flanges
  • Heat exchanger headers
  • Tube sheet
  • Sight gauges
  • Manways
  • Valve bonnets

Our wire wrap technique creates a barrier to hold a sealing compound that fills the volume of the gap above the flange bolts. The compound is injected online through stud bores to create a new seal, in turn stopping the leak.

Composite Wraps

Composite wraps offer a solution for restoring the strength of corroded, weakened, and dented pipe, tank walls and associated structures. Colt’s repair techniques restore the damaged asset’s pressure-containing capability. Colt selects an engineered product suitable to the line and equipment conditions to repair:

  • Wall thinning
  • Pitting
  • Dents
  • Gouges

The composite wrap works by sharing the hoop load carried by the pipe or tank wall. A high-compressive strength material fills the external defect to its original wall thickness, preventing leaks from the compromised structure.

Valve Packing

Over time, valve packing glands can leak, causing safety, environmental, and operational hazards. We utilize a drill and tap procedure to effectively seal leaks on pressurized equipment ranging from vacuum to 5,000 psig and temperatures ranging from cryogenic to 1,850 °F, including:

  • Actuation valves
  • Control valves
  • Safety valves

Colt technicians ensure the sealant used to seal the leak is comparable to the valve manufacturer’s original packing material so it will not harden or render the valve inoperable.
