Pipe freeze plug service is a non-intrusive, cost-effective, and quick method to perform pipeline maintenance and modifications without draining the system. Using liquid nitrogen, we can isolate your problem area in the pipeline or vessel by freezing the product inside the pipeline to form a solid ice freeze plug forming a linestop within the pipeline. This allows for very little drain-down or refill and, in many cases, no system downtime. Once the work is complete, the plug or plugs are thawed and the line is restored to operation while leaving the pipeline intergerity in tact. Standard freeze plugs range in size from 1/2" to 36" OD and can be performed on most fluids including petrochemicals with pressures in excess of 3000 psi. If you need a pipeline plug larger than 36" contact us
