Fin Tube and Alloy Tube Guides
Selection guides written from the dimensions and grades we actually produce, for engineers specifying heat exchanger and boiler tube.
Fin Tube Types Explained and How to Choose OneL type, embedded, extruded, low fin, spiral, H type, longitudinal and stud fins compared by bond, temperature limit and fouling behaviour, with the size range of each.
Embedded vs Extruded Fin Tube for Air Cooled Heat ExchangersA direct comparison of G type embedded and extruded bimetal fin tube: bond mechanism, base tube range, atmospheric protection, fin pitch and where each one is the right answer.
Why H Type Fin Tube Survives Ash Laden Flue GasHow the split fin geometry of H and HH type finned tube keeps economizer banks cleanable, with fin pitch, fin thickness and base tube data for coal and biomass boilers.
Duplex or Nickel Alloy Tube How to DecideWhen duplex stainless is enough and when the service needs a nickel alloy, with grade lists, applicable ASTM and ASME specifications and the size ranges available.
Tubesheet and Tube Fit Up What to SpecifyWhat a tubesheet enquiry needs to contain - hole pattern, pitch, grooving, plate material and tube dimensions - and why plate and tube should come from one drawing.
How Heat Exchanger Tube Is Inspected Before It ShipsThe test sequence applied to seamless and finned tube at Fanbang: eddy current, hydro test, tensile, flattening, flaring, hardness, chemical analysis and dimensional inspection.FAQ
About These Guides
Where do the numbers in these guides come from?
From our own product pages - the base tube, fin and plate ranges our production lines run. Nothing in the guides is a generic industry figure.
Can your engineers review our selection?
Yes. Email [email protected] with the stream data and the bundle envelope.
Do you publish these as PDFs?
Documents are issued against an enquiry so that the version you hold carries your tube size, grade and test scope.
A Question the Guides Do Not Answer
Send the stream data and the bundle envelope. Our engineers answer selection questions before there is an order on the table.
