Shell and Tube Heat Exchangers
Fixed tube-sheet, U-tube and floating-head exchangers for oil refineries, chemical plants and high-pressure industrial processes.
At R&D Therm we specialise in designing and manufacturing shell and tube heat exchangers — the most widely-used heat exchanger type in oil refineries, chemical plants and other high-pressure industrial processes.
Our exchangers are built in compliance with ASME Section VIII standards and carry the ASME U-Stamp for pressure vessels. We are also IBR certified for steam-side service.
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.
- Efficient heat transfer for continuous industrial operation
- Simple, cost-effective design with field-proven reliability
- Custom-engineered tube layouts, baffles and materials
- ASME-certified construction for global compliance
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. In 2024 we dispatched a 48.5 MT distillation column measuring 4.5 m × 23 m.
Which codes and certifications do you build to?
We are ASME U-Stamp certified for pressure vessels (Section VIII Div 1 & 2), IBR-approved for boilers and steam pressure parts, and routinely build to PED (CE marked) for European exports. Tanks follow API 650 / IS 2062 as applicable.
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. We have qualified welders and procedures for each material.
What is your typical delivery timeline?
Standard pressure vessels and heat exchangers typically ship in 12 – 16 weeks. Larger columns, reactors and complete process skids ship in 16 – 22 weeks depending on scope and material. Every quote includes a milestone-based delivery schedule.
Do you provide third-party inspection support?
Yes — we work routinely with Lloyd's Register, BV, TUV, DNV, SGS and customer-nominated inspection agencies. Hold points, witness inspections and full documentation packs are part of every job.
Do you supply equipment with standard accessories and instrumentation?
Yes — pressure gauges, safety valves, drain valves, manholes, ladders, platforms and instrumentation nozzles are supplied as standard. Auto-drains, PLC / DCS-ready packages and platforms are available as options.
Can you offer site erection and commissioning support?
We routinely send engineers to site for erection supervision, hydro / loop checking and commissioning support. Full piping and erection is also part of our scope on turnkey skid jobs.
