Our modern ASME code production facilities are clean and spacious allowing for proper material segregation.

We are dedicated to meeting your business needs by offering a broad range of design and fabrication capabilities which include:

  • A wide selection of pressure and temperature vessels
  • Shell and tube type fixed tubesheet or u-tube heat exchangers
  • Conventional reactors or reactors with dimpled and half-pipe jacketed columns
  • Evaporators, condensers, crystallizers, towers, scrubbers, deionizers, piping systems, and modular skids
  • Specialty heat exchanger rebuilds
  • Our technical staff is highly-trained with extensive metallurgical knowledge, design experience, ingenuity, and flexibility utilizing the latest in computer-assisted design technologies. Our fabrication facilities contain the latest tools and equipment necessary to safely complete any project in a timely and cost-effective manner.
  • In-house capabilities include finishing operations on completed products, and we routinely prepare surfaces by steel grit or glass bead blasting to specified requirements. In addition, we apply primers and finish paint coatings to specified mil thicknesses using specialty finish coatings from major manufacturers. All finishes are applied in our climate controlled industrial coating facility.

Field Fabrication / Repair

We also provide field fabrication services to clients at their facilities for fabrication, repair, and modification of existing pressure vessels, boilers, and heat exchangers. If your equipment is too large to transport as a complete fabricate component, we will fabricate it in sections and send a highly qualified and experienced Fabrication Services Team to your facility for final field assembly.


We have been granted Certificates of Authorization to provide fabricated products in compliance with the American Society of Mechanical Engineers (ASME) Section I & VIII, Division I requirements.

These include:

  • Compliance stamps “U” (Unfired Pressure Vessels) “S” (Boiler Manufacture Section I)
  • The National Board of Boiler and Pressure Vessel Inspectors “R” (Boiler & Vessel Repair & Alteration)
  • Shell and tube heat exchangers are fabricated in compliance with:
    • Tubular Exchanger Manufacturers Association (TEMA)
    • Unfired Heat Exchanger (UHX) B, C, and R
  • AWS D1.1
  • B31.1 and B31.3 Code
  • American Petroleum Institute (API) – 650, 620, and 653

Quality Assurance and Control:

Roberts strictly adheres to a number of Quality Assurance and Quality Control Programs. As part of this process, we undergo yearly audits through our Authorized Inspection Agents and full audits every three years by the ASME and the National Board. Through the audit process and our ongoing internal efforts, we keep our quality program up to date with the latest amendments and revisions to the ASME code.

Our written Quality Control / Quality Assurance program is committed to zero defects both technically and aesthetically. All vessels are built to the same standards, whether code stamped or not. In addition to in-house radiography capabilities, we are equipped to perform various types of leak tests, (including Helium Leak Testing), proof tests, and ultrasonic thickness and material verification tests. We will develop a Project Specific QA / QC Program tailored for our clients’ unique needs.

Positive Material Identification:

  • Was the correct material used in your equipment?
  • Was the correct filler metal used to weld your equipment?
  • What type of material do you have in that pile of steel on your site?
