ASME "R" Stamp National Board Certified Father & Son Since 2018

Pressure Vessel & Boiler Repair, Code Stamped.

McPherson Specialty Welding Services holds an ASME "R" Stamp from the National Board. We repair and alter boilers and pressure vessels to NBIC code, on-site at the plant or in the shop. When a plant goes down, we are who they call.

Repairs & Alterations, Built to Code.

An ASME "R" Stamp authorizes welded repairs and alterations to boilers and pressure vessels under the National Board Inspection Code. That is the core of this shop. Qualified procedures, qualified welders, and an Authorized Inspector who signs off before the job is closed.

Pressure Vessel Repair & Re-Rating

Weld repairs, wall and nozzle restoration, and re-rating on pressure vessels, separators, and tanks. Brought back into service to code, not patched.

Boiler Repair & Retubes

Boiler tube repair and replacement, retubes, and pressure-part repair. The work that keeps a boiler legal to fire and safe to run.

Nozzle Additions & Modifications

New nozzles, connection changes, and code alterations welded and documented to NBIC requirements.

Crack Repair & Weld Restoration

Crack excavation and repair, weld build-up, and metal restoration on pressure-retaining parts that have to hold.

Plant Down

Shutdowns Are What We Do Best.

When a vessel or a boiler shuts a line down, every hour costs you. Emergency and shutdown work is our bread and butter. Call and we get a certified welder on it, on-site, fast.

03 / Why It Matters

An Uncertified Repair Isn't a Shortcut. It's a Liability.

Welded repairs and alterations to boilers and pressure vessels are governed by code for a reason. The wrong fix from the wrong shop can void your compliance and your insurance. This is why the stamp exists.

/ 01

The "R" Stamp Is the Standard

Repairs and alterations to pressure-retaining equipment are meant to be done by a shop holding a valid National Board "R" Certificate, to NBIC code. We hold it.

/ 02

The Welder Stamps His Own Work

No call center. No mystery subcontractor. The welder who makes your repair is qualified to the procedure and puts his name on it.

/ 03

Every Job Is Documented

Material traceability, qualified procedures, and an R-1 report signed by the Authorized Inspector. Inspection-ready, every time.

Where it started

Father and Son, Since 2018.

The McPhersons on the job, father and son The McPhersons
The gray Jeep and trailer that ran the first job in 2018 The first job, 2018

The first job this company ever got paid for was R-Stamp work. The crew was the old man, a buddy, and his son. His son's truck was down, so we hooked the trailer to the only thing that would pull it, an old gray Jeep, and rolled out.

We got it done. That is still how it runs. A certified welder, the people who trust him, and whatever it takes to put the job back in service.

Built by hand since 2018. The name on the work is the name on the door.
