Fin Tubes — OD 15-220 mm
We manufacture spirally crimped fin tubes, where the fin is bonded to the tube mechanically rather than welded — a bond that resists loosening under thermal cycling and vibration, at a lower cost than welded fin tube. Used in heat exchangers, boilers, condensers, HVAC, and process heating or cooling.
Fin tubes are produced to order on our own PTF finning machines at Pithampur near Indore and supplied to heat exchanger builders, boiler makers and process plants across India. Base tube, fin material, fin height and pitch are set from your thermal duty, and a sample can be finned for approval before the balance quantity is run.
- Standards
- ASTM A106, A179, ASME
- Tube Material
- Carbon, Stainless, Alloy
- Delivery
- Ex-works Pithampur, Indore — by road anywhere in India
- Built and supplied
- Made at Pithampur, Indore — delivered across India
Spirally Crimped Construction
- Process: Fin strip is wound around the base tube at a precise angle; crimping forms interlocking ridges for a durable mechanical bond (optional tack welding at ends for extra security)
- Benefits: Strong thermal contact, improved heat transfer coefficient, cost-effective versus welded fin tubes, suitable for heating and cooling applications

Supply and Support in India
- Delivery: By road from Pithampur, bundled and end-capped, cut to the lengths on your drawing.
- Material: Base tube and fin strip procured against your specification, with mill test certificates passed on with the consignment.
- Free issue: We will fin base tubes supplied by you, which is usually the cheaper route where you already hold the tube.
- Sampling: A short sample run for bond and fin-height approval before the balance quantity goes into production.
- Commercial: Quoted in Indian rupees per metre or per tube, ex-works Pithampur, with GST invoiced separately.
Frequently Asked Questions
What fin tube sizes do you manufacture?
Tube outer diameters from 15 to 220 mm, fin heights from 6.35 to 38 mm, and fin densities of 10-50 fins per inch.
What materials are available for fin tubes?
Base tubes in carbon steel, stainless steel, and alloy steel, with fin material chosen for the heat-transfer duty — commonly aluminum or steel strip, spirally wound and crimped for a strong mechanical bond.
Is the fin tubes customised to my requirement?
Yes. Every machine we build is custom-engineered — capacity, dimensions, and configuration are matched to your line. Send your requirement via the enquiry form or call +91 91091 02280 for a firm quote. Equipment is manufactured to ASTM A106, ASTM A179, ASME, and test certificates are available on request.
Can you fin base tubes we supply, and how are the tubes delivered in India?
Yes — finning tube you already hold is usually the cheaper route, and we quote for it as readily as for tube and fin together. Production runs on our own PTF finning machines at Pithampur near Indore, and the tubes go out by road, bundled and end-capped to the lengths on your drawing.
