More Than a Repair: How DSI’s R Stamp Welding Services for Oil and Gas Strengthen Operations 

Every maintenance or operations manager in oil and gas knows the stakes. One weak weld can bring production to a halt, compromise safety, and cost millions in downtime. That’s why R Stamp welding services for oil and gas have become an essential part of maintaining operational integrity across the industry. 

For Design Solutions and Integration (DSI), this certification isn’t just a credential, it’s a commitment to doing the job right. In the high-pressure world of field services, DSI’s R Stamp welding accreditation means every repair, modification, and test pressure-retaining equipment meets the highest industry standards. 

The Challenge: Why Ordinary Repairs Aren’t Enough 

In oil and gas production, time is money, and so is safety. Field crews often face emergencies where pressure vessels or pipelines fail unexpectedly. Quick fixes might get the system running again, but without proper certification, those repairs can lead to future failures, compliance issues, or worse, safety incidents. 

As Charlie Gallinger, DSI’s Field Services Manager, explains, “Every operator knows that a poor weld isn’t just a weak spot in a line, it’s a weak spot in the entire operation.” 

DSI’s team encounters these realities daily. From saltwater disposal plants to central tank batteries, their welders respond to urgent calls at all hours. These aren’t controlled shop environments; they’re live, high-demand sites where every minute matters. 

Without certified repair capability, operators in places like North Dakota’s Bakken formation often must bring in out-of-state specialists, losing valuable hours or days in the process. DSI eliminates that delay by being both local and fully accredited. 

What R Stamp Certification Really Means 

The R Stamp isn’t just another license; it’s an accreditation governed by the National Board of Boiler and Pressure Vessel Inspectors (NBBI). It authorizes a company, not just individual welders, to repair or alter pressure-retaining items such as boilers, piping, and pressure vessels. 

To earn and maintain this authorization, companies must: 

• Maintain a written Quality Management System (QMS) that meets the National Board Inspection Code (NBIC). 

• Work under a current agreement with an Authorized Inspection Agency (AIA) for independent oversight. 

• Qualify welders, procedures, and materials under ASME Section IX standards. 

• Document and register all work, including tests like radiography and hydrostatic pressure verification. 

As Charlie puts it, “These aren’t your average repairs. An R Stamp repair can involve 40 or more pages of documentation, drawings, and test records. Every weld we do must match or exceed the original manufacturer’s specifications.” 

That level of discipline is what separates certified field services from general welding. Each repair is reviewed, tested, and inspected, often with radiographic testing and state oversight, to ensure full compliance and reliability. 

How DSI’s Field Services Bring Certification to the Field 

For DSI, the R Stamp certification is just one part of a larger, vertically integrated solution. The company’s Field Services division blends emergency responsiveness with long-term modernization. 

Charlie explains that the process often starts with a late-night call: a facility goes down, a line ruptures, or a tank fails. “We’re a 24/7 operation,” he says. “Our welders are ready to mobilize, and if it’s an R Stamp repair, we handle everything from paperwork to testing, on-site.” 

DSI’s teams perform a complete sequence of inspection and certification steps: 

Step 1: Inspect and Diagnose 

Certified technicians evaluate the damage, review the vessel’s original code documents, and determine the proper repair procedure. 

Step 2: Repair and Certify 

Using R Stamp-approved welding procedures, the team performs the repair, supported by non-destructive testing and X-ray inspections. Each project is documented and verified by an Authorized Inspector before the job is signed off. 

Step 3: Modernize and Maintain 

Beyond addressing the immediate issue, DSI identifies opportunities to upgrade materials, improve flow systems, and retrofit outdated designs to help operators reduce risk and extend equipment life. 

Charlie adds, “We don’t just patch the problem. We help our customers come out stronger, more efficient, more compliant, and better prepared for the next challenge.” 

Safety Isn’t Optional, It’s Engineered Into Every Job 

Oil and gas welding is inherently hazardous. DSI’s welders follow strict safety protocols before any repair begins. Each field crew carries dual gas monitoring systems, lockout-tagout equipment, and emergency air packs to ensure safety in confined or high-risk areas. 

“We are the fire when we come on location,” Charlie says. “If there’s gas in the air, it’s our job to make sure the site is safe before we strike an arc.” 

That mindset defines DSI’s field culture. Safety isn’t an add-on; it’s part of every weld, inspection, and certification step. 

The Power of Integration: Field Services Plus Everything Else 

What makes DSI different is its integration. Field Services is one division in a system that also includes fabrication, electrical, engineering, and panel shop teams. This structure allows DSI to take projects from repair to full modernization without juggling multiple contractors. 

If a customer needs a piping upgrade or system redesign, DSI’s team can handle it. From creating new isometric drawings to fabricating replacement components and installing them in the field. 

Charlie notes, “Customers call us because we’re a one-stop shop. They know we’ll solve the problem, simplify the process, and make sure it’s done right the first time.” 

From Risk to Reliability: The Results of Certified Work 

R Stamp welding services protect more than just metal; they protect uptime, compliance, and trust. The difference between uncertified and certified repairs shows up in every metric that matters: 

Before	After
Risk of failed repairs	Certified, code-compliant welding
Multiple contractors	One vertically integrated partner
Reactive maintenance	Proactive modernization and safety
Unplanned downtime	Reliable, long-term uptime

Every weld DSI performs under its R Stamp certification is a statement of integrity and precision. “Every weld tells a story,” Charlie says. “We make sure it’s one of safety, reliability, and progress.”
