Issue the purchaser datasheet or EPC specification with code references.
Shell-and-tube and related heat exchangers are the core supply. Reactors, columns and steam-jet vacuum equipment are quoted when included on the RFQ.

Sector overview
What oil & gas buyers specify
Oil, gas and upstream/downstream projects specify heat exchangers against purchaser datasheets — often with named mechanical codes, NACE material notes, fouling factors and third-party inspection. The fabricator must build to that document, not to a generic catalogue rating.
Ohm Engineers manufactures in India and supplies to domestic and export sites as commercially agreed. NACE, DNV, PED and U-stamp are applied only when the order requires them and the relevant authorisation exists — they are not listed as credentials currently held.
We do not claim named NOC, operator or refinery customers on this page.

Industry challenges
- Named mechanical and pressure codes
- Fouling hydrocarbon streams
- Export documentation and packing
- Third-party inspection when specified
How Ohm Engineers responds
- TEMA practice and ASME VIII-1 or IS 2825 when specified
- Fixed-tubesheet, U-tube, double-pipe or kettle as the duty requires
- ITP hold points including TPI when the PO requires it
- Packing and documents for Indian or overseas dispatch

How supply works for oil & gas
FAQ
Common questions — Oil & Gas
- Do you hold ASME U-stamp?
- ASME VIII-1 is a design basis when named on the enquiry. U-stamp authorisation is not claimed here unless documented for a specific order pathway.
- Can you meet NACE MR0175?
- Material selection follows purchaser NACE or corrosion notes when they are on the specification.
- Do you export to the Middle East?
- Yes, when specification and commercial terms align. Equipment is manufactured in Vadodara — see our Global pages for export hubs.
