Leak Sealing & Composite Pipe Repair

Active leaks at pipes, headers, and vessels waste product and eat into nearby steel before a shutdown can be scheduled. Our crew seals the live leak cold while the line stays pressurized, then overwraps the repair for a permanent fix. Production continues with no hot work and no product evacuation. We use oil-tolerant compounds where they are needed, so a leak at a transformer tank, a gearbox case, or a weld seam can be sealed directly onto oil-wet steel. The oil film that stops conventional adhesives from setting is not a problem for the right compound, and the repair is done in place with no draining.

The same cold, in-service approach extends to gas. SF6 leaks at switchgear flanges and seals release an expensive insulating gas and chip away at equipment reliability. We seal the leak path while the gear stays in service, so the leak stops without evacuating the SF6 or scheduling an outage. In every case the principle holds: stop the loss now, on the running unit, and leave the asset ready for service.

Through-wall corrosion, external pitting, and mechanical damage thin pressurized pipes and vessels long before a replacement turnaround comes around. Pinholes and corrosion pits open leak paths in pipe and tank walls, often on wet or oil-contaminated steel. Our crew rebuilds the corroded wall and seals the defects with cold-cure compounds that bond to damp, contaminated surfaces, then returns the line to service without welding. Where the wall has lost strength, we apply an engineered resin and fiber composite wrap with the line online, qualified to the methods recognized in ISO 24817 and ASME PCC-2, so the pipe recovers its design pressure rating. Belzona SuperWrap II is one of the systems we install for this work.

Bends, tees, and elbows are the first fittings to go, because flow turbulence concentrates erosion and corrosion at every change of direction. A flat wrap will not follow that geometry. Our crew lines and wraps the contoured fitting with a composite system that conforms to its shape, so the elbow or tee returns to service without cutting out the spool and re-welding it in. The repair follows the part, not the other way around.

Flange faces corrode and weep at the gasket joint while the exposed bolting seizes. That combination opens a leak path and makes the next disassembly a fight. Our crew encapsulates the flange in a cold-cure compound that seals the joint and protects the bolting at the same time. The weep stops, the corrosion under the encapsulation stops, and the assembly stays free so the joint can be broken cleanly when planned maintenance comes due.

This is field work and shop work both. Simple flange and fitting jobs go fast on site, and components that can come off are prepped and repaired in our climate-controlled shop, where surface preparation and cure conditions stay under control regardless of Louisiana weather.

The outcome a maintenance buyer cares about is the unit running and the leak gone. Sealing and wrapping cold means no hot work permit, no isolation, and in many cases no shutdown at all. The lost product stops, the corrosion around the leak stops spreading, and a line headed for an unplanned outage keeps running until you choose to take it down. A composite wrap returns thinned pipe to its pressure rating and buys years of service from an asset that looked like a replacement.

With decades of field experience, a strong safety record, and around-the-clock on-call response, our crew shows up, controls the surface prep, makes the repair, and gets the unit back in service. The leak is the subject, the running plant is the result.
