Product
Double Pipe Heat Exchangers
A double pipe exchanger is the simplest heat exchanger there is: one pipe inside another. It is ideal for small heat duties, very high pressures and temperature crosses, and sections can be added later as your process grows.
Why customers choose it
True counter-current flow
Handles temperature crosses in a single unit.
High pressure
Small diameters keep walls thin at high design pressure.
Modular
Add sections in series or parallel as duty changes.
Easy to clean
Inner pipes can be removed for mechanical cleaning.

Questions buyers ask us
Double pipe or hairpin: what's the difference?
A hairpin is a double pipe exchanger bent into a U so both ends sit together, often with several tubes inside the outer pipe. Hairpins handle bigger duties in a compact footprint; straight double pipe units suit the smallest duties.
Do you ship to the UAE, Saudi Arabia and the rest of the GCC?
Yes. Both our factories are in Coimbatore, about 195 km from Cochin port, with Tuticorin and Chennai also within reach. We pack for sea transport and ship to ports such as Jebel Ali, Khalifa Port, Dammam, Jubail, Sohar, Hamad and Shuwaikh. Our equipment is already in service with ADNOC, PDO Oman, OQ, QAPCO, Kuwait Oil Company and Ma'aden.
Can our inspector or a third-party agency witness the tests?
Of course. We regularly work with Bureau Veritas, Lloyd's Register, TÜV NORD, SGS, HSB and other agencies, and your own inspector is welcome at any stage.
