On-Stream Leak Sealing Services
Leaks are an ongoing problem for refineries and plants and sealing them properly requires knowledge and precision. At PSI,
our team of skilled experts use the highest quality sealants and hardware to evaluate and repair pressurized piping leaks safely and effectively.
Injection Rings
And Cap Nuts
PSI utilizes custom hardened steel injection rings and cap nuts for most flange and bonnet repairs. Our hardware is constructed of long-wearing carbon or stainless steel with sizes from 1/2” to 2” or larger. Each injection ring is installed beneath an existing nut on your equipment or the nut is replaced with a cap nut. An injection valve is then screwed in with the sealant injected through the studbore and into the failing gasket area—with no drilling necessary. Our hardware allows for a smooth sealant flow and easy removal when the equipment is repaired on shutdown. No holes are drilled into flanges, ensuring they retain their original integrity.

Industrial Sealants And Packaging
No matter the leak, we have the sealant to fix it. We utilize only specially formulated products to gain the advantage over water, air, steam or hydrocarbon leaks.
Injection Valves
Our injection values are machined from solid stainless stock, ensuring their reliability. We carry sizes from 1/16” to 1/4” NPT, and specialty and high-pressure injection valves are also available upon request.
