Leak Repair

ELIMINATE DOWNTIME WITH FAST ON-LINE LEAK REPAIRS


Colt helps eliminate downtime or lost production; repairing and sealing leaks on-line, onsite, and under pressure to keep critical assets running. Industrial leak repair companies such as Colt specialize in providing innovative approaches to solve the most difficult challenges quickly, safely, and effectively.

With our professional and technical capabilities to engineer, design, fabricate and install all standard and custom products, we consistently deliver the best on-line leak repair solutions and highest level of service in the industry.

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 leak repair

VALVE PACKING


Over time, valve packing glands can leak, causing safety, environmental, and operational hazards. Industrial leak repair companies such as ours 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.
