Corrosive process streams, hygienic duties and aggressive cooling water all call for different base tube materials — the fin geometry usually stays the same.
Process coolers and heaters
Chemical plants use finned tubes wherever the cooling or heating medium is air. Stainless steel 304, 316L, 321, duplex and titanium base tubes are all available with aluminium, copper or stainless fins, and the fin can be laser welded when a thin wall must not be annealed.
Common duties
- Reactor jacket cooling and product coolers.
- Acid and caustic dilution coolers (material dependent).
- Solvent recovery condensers.
- Dryer and crystalliser air heaters.
Materials and compatibility
Aluminium fins are not suitable for strong alkalis or acids in the air stream; in those cases we supply stainless or copper fins, or protect the aluminium with an epoxy or phenolic coating. Tell us the air-side and tube-side chemistry and we will shortlist the materials rather than let you over-specify.
Ask for a material recommendation
Tell us the tube diameter, fin height, fin pitch, materials and quantity — we reply with price and lead time within one working day.
