Process Piping

More than 40 years of experience in process piping puts us in a league of our own.

From simple plumbing to high pressure piping systems for commercial use, we have the know-how to design, build, and repair numerous pressure vessel types and components. And we have the certifications to prove it! Whether a brand new building, a renovation, or an alteration, know that your piping project will be handled with top-notch care and expertise.

Our Piping Services

  • Piping connections to production machinery either in new installations or service and repair.
  • Design and installation of high pressure gas piping systems.
  • Domestic water piping.
  • Piping for air, water, plumbing, steam, gas, oil, chemical or other fluids required in manufacturing process.


  • Holders of the American Society of Mechanical Engineers (ASME) issued “S” stamp. This means that PSI has been authorized by the ASME to manufacture boilers and power piping.
  • Authorized by National Board holder of “R” stamp to perform repairs to high pressure vessels. This means that PSI has been authorized by the National Board to repair boilers and pressure vessels.

Why We Stand Out

  • Fabrication & Installation. Having our own 30,000+ square feet in-house fabrication shop sets us apart from the competition in a huge way. It means you’ll reduce labor costs and see a faster turnaround on your project. Your materials are custom fit to your specifications, and you have minimum onsite business interruption since most work is done at our location.
  • Service & Inspection. PSI is licensed and certified to build, repair, and perform inspections on most pressure vessels.
  • Professional & Experienced. Many PSI technicians hold trade licenses in multiple disciplines, so we perform more services in-house with fewer technicians, just one way we keep labor costs low.

How We Work

  • Safety First. Our safety program is award-winning. All of our technicians hold OSHA-30 status. PSI is a Platinum member of the Associated Builders and Contractor’s STEP Safety Management System. This means that PSI is 242% safer than the industry average. We have an impeccable safety record and are constantly enhancing our safety program to reduce job site incidents even further.
  • Guaranteed. If you aren’t 100% completely satisfied, PIPING SYSTEMS’ PERFECTION PROMISE means that IT’S FREE!
  • Easy To Work With. We embrace a challenge. We thrive on wowing customers by consistently “going the extra mile.”

Emergency Service

Having a problem that can’t wait? Our 24-hour emergency hotline is always open to your call, whether you are a new or existing customer. You can call us directly at (508) 644-2221 or hit the Emergency Services button at the top of the page, and we guarantee a response within 1 hour.

Maintenance & Repair

Why wait for trouble when you’ve got people who can spot it a mile away?  We understand that a small issue now can turn into a bigger issue down the road. So stay on guard by scheduling a maintenance visit from the experts at PSI.

Perfection Promise

All repair and maintenance work is guaranteed. But guarantees are only as good as the people behind the company giving them.  In our PSI Perfection Promise (which we rarely have to invoke), we guarantee that If you aren’t 100% completely satisfied, then it’s free.  No hassles, no hard feelings!
