Live Pipe Leak Seal & Composite Wrap
Live leak sealed and a degraded process line reinforced with an engineered composite wrap, no welding and often no shutdown.
What was failing
A process line developed a weeping leak after corrosion thinned the pipe wall over a run of the pipe. Lost wall thickness reduces the integrity of the section and the leak puts product and people at risk. Welding a clamp or replacing the spool means hot work and, in most cases, a shutdown, both of which the plant wanted to avoid. The line needed to stay in service while the repair was made.
How AAS approaches it
We seal the active leak on the live line, then prepare the corroded run and build an engineered composite wrap over it. We design the wrap to recognized composite-repair standards, ISO 24817 and ASME PCC-2, so the repaired section is reinforced to a defined case. The work uses no welding, and in many cases we complete it while the line stays in service.
Assess and design
We inspect the leak and the run of lost wall thickness and design the composite wrap to ISO 24817 / ASME PCC-2 for the line conditions.
Seal the live leak
We stop the active weep on the line so the surface can be prepared and the wrap can cure.
Surface preparation
We clean and roughen the pipe over the degraded section to give the composite a sound surface to bond to.
Install the composite wrap
We build up the engineered SuperWrap II layers over the prepared run to reinforce the thinned section, with no welding required.
Cure and return to service
We let the wrap cure and inspect the finished repair, keeping the line in service through the work where conditions allow.
