U Tubes




■BANGWIN’ in-house u bent tube manipulation facility enables us to offer rapid turnaround times on your requirements for u bent
heat exchanger tubes in any material.
■All U bend tubes are manufactured in accordance with TEMA R specifications.
■Our competitive prices, rapid quotations and bespoke packing ensure we consistently deliver the highest quality of service.




Welded Finned Tubes



BANGWIN can supply either solid or serrated welded finned tubes. These tubes are manufactured specifically to suit the high
temperature environment found in furnaces/boilers and waste heat recovery equipment.
Our high frequency serrated fin is a metal strip that has been serrated or cut and then helically wound around the specified tube.
The fin is welded to the tubular base using the high frequency weld process.
The fin can be applied to a wide variety of tubular material with configurations to suit your requirements.


tube sizes
  3/4" O.D. TO 8" NPS (8.625" O.D.)
fin heights
3/8" TO 1 1⁄2"
fin thickness
20 ga. (.035") to 12 ga. (.102") segmented width: 4.5mm or 8mm
segment width
4.5mm OR 8mm
fin pitch
1 to 7 fins per inch
material
any material or combination that can be resistance or arc welded


Integral Low Fin Tubes



Integral low fin tube has the advantage that it can improve the thermal performance of a heat exchanger without the necessity forchanging shell size, flow arrangement or the repositioning of piping. The external surface of the tube is increased by theformation of "low fins" by direct extrusion from the material of the base tube.
