Everything you need to know about ASME-certified custom heavy metal fabrication, pressure vessel work, service areas, and field capabilities. At Boardman, we have been building heavy industrial equipment since 1910. Here’s what you need to know about who we are and how we operate.
Boardman is a custom heavy metal fabricator based in Oklahoma City. Our team designs, engineers, and fabricates heavy industrial equipment, including ASME pressure vessels, distillation towers, storage tanks, reactors, and custom steel structures for clients across a wide range of industries. If your operation needs a precision-built piece of industrial metal equipment, Boardman builds it from start to finish under one roof.
Boardman has been fabricating since 1910, and that’s over 115 years of experience. The company started as a tank manufacturer serving Oklahoma agriculture and grew into a nationally recognized industrial fabricator while maintaining its founding commitment to quality and accountability.
Here are a few things about our team that stand out:
We are located at 1135 S. McKinley Ave, Oklahoma City, Oklahoma. Our facility encompasses 140,000 sq. ft. across four separate fabrication shops operating under one roof.
Our team has deep, documented experience in:
If your industry demands ASME-certified, engineered-to-spec heavy metal fabrication, Boardman has almost certainly built something like yours before.
Yes, our field service work is available in seven states
If your facility is within that footprint, Boardman can dispatch a crew directly to you for on-site fabrication, installation, repairs, and inspections.
Within the field service states, our specialized crews can handle:
Heavy metal fabrication is the backbone of industrial operations. If you’re sourcing a fabricator for the first time or comparing options, these are common heavy metal fabrication FAQs with straight answers.
Heavy metal fabrication is the process of designing, cutting, welding, and assembling large-scale metal components and equipment built to withstand extreme industrial conditions, such as high pressure, high temperature, and corrosive environments. With Boardman, every piece is engineered and built to your exact specifications.
Scale, code compliance, and consequence. Heavy metal fabrication involves industrial-grade equipment where failure isn’t an option. That means strict adherence to ASME, AWS, API, and AISC standards, not just good craftsmanship.
It depends on complexity, size, and material availability. A straightforward vessel might take weeks. A large, multi-component project with custom engineering can take months. Boardman assigns a dedicated project manager to keep your timeline on track from day one.
Custom, one-off fabrication is at the core of what Boardman does. Most projects are built specifically to your specs, your drawings, and your application. If your needs go beyond a single component, reach out, and we can talk through what that looks like. Every project starts with a conversation.
At Boardman, we use SAW (Submerged Arc Welding), MIG, TIG, and other multi-process welding methods. Our team holds over 1,000 qualified welding procedures, meaning they have a proven, code-compliant process ready for virtually any material and joint configuration.
Both. We fabricate equipment in our 140,000 sq. ft. Oklahoma City shop and dispatch field crews to seven states, including OK, TX, NM, CO, AR, MO, and KS, for on-site installation, repair, and inspection.
ASME pressure vessel standards exist for safety. If your operation involves pressurized equipment, what you don’t know about code compliance can cost you. Here are some ASME pressure vessel FAQs you can check before your next project.
An ASME pressure vessel is a container designed to hold gases or liquids at pressures significantly different from ambient. It is built and certified to meet the American Society of Mechanical Engineers Boiler and Pressure Vessel Code (BPVC). The ASME stamp on a vessel indicates to inspectors, regulators, and clients that it was built to the highest-verified standard in the industry.
Boardman holds ASME Section VIII Division 1 and Division 2 U-stamps for pressure vessel fabrication, and the National Board R-stamp for repairs and alterations. The company also adheres to AWS, API, and AISC code standards.
Division 1 covers the majority of pressure vessel applications and uses a more prescriptive design approach.
Division 2 applies to higher-pressure, more demanding applications and uses an alternative design-by-analysis method, allowing for thinner walls and lighter vessels when engineered correctly. Boardman is certified for both.
Boardman builds drums, separators, reactors, accumulators, heat exchangers, and other custom pressure vessels for refining, chemical processing, gas processing, hydrogen production, carbon capture, and more.
Boardman fabricates pressure vessels up to 16 feet in diameter, 200 feet in length, and 350 tons in weight, all within our Oklahoma City facility.
We use carbon steel, stainless steel, low-alloy steels, and clad materials. All of these are selected and fabricated to meet ASME code requirements for the specific pressure and temperature conditions of your application.
Yes. Boardman holds the National Board R-stamp, which authorizes the company to perform code-compliant repairs and alterations on ASME pressure vessels, both in-shop and on-site within its field service states.
Every heavy metal fabrication project starts with a conversation. Our team will work with you from first contact to final delivery. Here are the most common questions about Boardman’s process:
It starts with a conversation about your project scope, specifications, and timeline. From there, you decide how involved you want to be. Options include:
You drive the level of involvement. Our specialized team works around your project structure.
Scale, code compliance, and consequence. Heavy metal fabrication involves industrial-grade equipment where failure isn’t an option. That means strict adherence to ASME, AWS, API, and AISC standards, not just good craftsmanship.
Yes. Each project is assigned a dedicated project manager who handles communication, scheduling, and coordination across all phases, such as:
You won’t be chasing down multiple departments for updates.
Of course! Boardman maintains a project gallery featuring past fabrication work, including pressure vessels, separators, reactors, distillation towers, and more. View the Project Gallery →
When your operation is down, you need a heavy metal fabrication team that can move fast. Here are the most common questions about our emergency fabrication.
Yes, we offer dedicated Emergency Fabrication Services. Our team can fast-track engineering, expedite material procurement, and run multiple shifts to compress timelines when your operation can’t wait.
24/7 Emergency Line: 405-634-5434
Yes, emergency fabrication is available to any client, regardless of location. At Boardman LLC, our fabrication ships nationwide, and for clients within the field service footprint (OK, TX, NM, CO, AR, MO, KS), an on-site crew can also be mobilized when the situation calls for it.
You shouldn’t have to chase down answers or wonder if your fabricator truly understands what’s at stake. Reach out today, talk through your project, and make a plan that works for you.
