This case study outlines a successful project undertaken for a major contractor in the region, aimed at repairing a leak in an electrical distribution line with minimal disruption to power supply.
Pennsylvania
Line Owner: A Southwestern Pennsylvania Power Company
Line Size: 10.750” O.D.
Product: Dielectric Fluid 100 (DF-100)
Freeze Point: -184F
A prominent contractor contacted PFS Nitrogen Services to assist in pipe freeze isolations for one of the largest electricity suppliers in the area. The task was to identify and repair a leak in an electrical distribution line containing Dielectric Fluid, aiming to achieve this with minimal power disruption.
PFS was tasked with achieving the required freezes within 24 hours. The objective was to maintain the freeze at a temperature of -184°F for another 24 hours and then hold the freeze continuously for five days, as confirmed by the Distribution Line Company (DLC). The frozen pipe, containing Dielectric Fluid, was part of an electrical distribution system.
The execution plan for this project included several critical elements:
PFS achieved a successful freeze that was maintained for five days. This accomplishment allowed the electricity company to minimize customer power outages and target only the damaged section of the pipe for repair. The isolation process involved freezing dielectric fluid with a freeze point of -184°F in a 10" diameter pipe containing electrical cables.
A detailed plan was developed, reviewed, and approved, enabling the successful execution of two simultaneous freezes maintained for over 48 hours. This allowed the contractor to perform necessary upgrades to the piping and electrical system without any service interruptions. PFS has since completed several similar pipe freeze isolations for the same client.
