Heat transfer is at the core of nearly every process line, and getting it right means matching the right exchanger geometry to your fluid conditions, space constraints, and duty cycle. R&D Therm fabricates a full range of tubular heat exchangers, including conventional shell and tube units, pipe-in-pipe (double pipe) exchangers, trombone heat exchangers, and water preheaters, each built to handle a specific combination of pressure, temperature, and flow characteristics.
Every exchanger we build starts with your thermal duty specification. From there, our team works out the mechanical design: tube layout, baffle configuration, shell sizing, and material selection, before moving into fabrication. Tube bundles are rolled, welded, and tested to exacting tolerances, and every unit is validated against ASME and TEMA requirements before it leaves our shop floor.
We stay in our lane on mechanical design and fabrication. If you've already worked out the process side, we'll turn it into a exchanger that performs reliably for years, backed by full documentation and code compliance.
Questions buyers ask first.
What sizes can R&D Therm fabricate?
We can fabricate equipment up to 4.5 m in shell diameter, 33 m in overall length and 42 MT single-piece weight.
Which codes and certifications do you build to?
We are ASME U-Stamp certified for pressure vessels, IBR-approved for boilers and steam pressure parts, and routinely build to PED (CE marked) for European exports.
Do you handle exotic-alloy fabrication?
Yes — titanium, Hastelloy C-22 / C-276, duplex and super-duplex stainless steels, Sanicro 28 and 904L are routine work for our welding division.
What is your typical delivery timeline?
Standard pressure vessels and heat exchangers typically ship in 12–16 weeks. Larger columns, reactors and skids ship in 16–22 weeks.
Do you provide third-party inspection support?
Yes — we work routinely with Lloyd's Register, BV, TUV, DNV, SGS and customer-nominated inspection agencies.
What does R&D Therm do?
R&D Therm designs and manufactures process equipment including pressure vessels, heat exchangers, reactors, columns and process skids for industries such as chemical, pharma, oil & gas, etc.
