Integral Finned Tubes

integrally finned tubes by low finning / integral fin tube: type low fin:
integral low fin tube for use in situations where extended surface is required, but lack of space or heat exchanger type dictates otherwise.
available materials are stainless steel (304l, 316l, 321(h), 304h, 310, …), duplex, copper alloys, nickel alloys, hastelloy and titanium
integral low fin tube has the advantage that it can improve the thermal performance of a heat exchanger without the necessity for changing shell size, flow arrangement or the repositioning of piping.

the external surface of the tube is increased by the formation of ''low fins'' by direct extrusion from the material of the base tube.
size range / dimensions:
- tube size: 12,7mm, 15,88mm, 19,05mm and 25,4mm
- fins per inch: 16, 19, 26, 28, 30, 32, 36, 40 and 43 fins/inch dependant on material

quality test capabilities :
- non-destructive eddy current examination
- air under water testing
- hydrostatic testing (with fluorescent dye)
- fin profile examination at 50x magnification            
- dimensional & ring gage checks
