Engineering services included.
- 01Detailed mechanical design with FEA review.
- 02Mill-to-shop material traceability.
- 03Third-party inspection and code stamping.
- 04QA dossier and as-built drawings on despatch.
Why teams choose us.
- Full code compliance
- Material traceability with MTC
- Single-source fabrication
Constructed to code
Compliance & standards.
Every vessel, exchanger and skid we ship is engineered, fabricated and inspected to internationally recognised pressure-equipment codes.
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.
Can you offer site erection and commissioning support?
We routinely send engineers to site for erection supervision, hydro / loop checking and commissioning support.
