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 Valve/Cap Nuts

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.

CEO

Thank you for coming to our website. It is my hope that when you put your mouse down and decide to take action for your facility needs, that we’ve given you enough information for you to make PSI your first call for your specialty contracting needs.

I formed PSI to provide a better, more polished product for our customers in the power and petrochemical industries. To provide “old school” service that was based upon a handshake, and where a service company does just that, provide service. Not only provide service, but provide only the best service, with spot-on pricing, punctuality, professionalism and utilizes a “service with a smile” approach. The company, much like myself has modest roots, remains humble in its demeanor and yet is very driven to succeed and be the very best at what we do.
