Global PipeLine Solutions (GPLS)

The specialist for corrosion resistant and heat resistant stainless steels, duplex, nickel alloys and titanium

Company Integrally finned tubes by low finning / Integral fin tube: type low fin:

Flanges and forgings Integral low fin tube for use in situations where extended surface is required, but lack of space or heat exchanger type

dictates otherwise.

Fittings Available materials are stainless steel (304L, 316L, 321(H), 304H, 310, …), duplex, copper alloys, nickel alloys, hastelloy

and titanium

Welded pipes and tubes

Integral Low Fin Tube has the advantage that it can improve the thermal performance of a heat exchanger without the

Seamless pipes and tubes necessity for changing shell size, flow arrangement or the repositioning of piping.

Stainless Steels The external surface of the tube is increased by the formation of ''low fins'' by direct extrusion from the material of the

base tube.

Nickel alloys and titanium

Tubes With Integral Fins

In specifying finned tubes you should advise:

1) Number of finned tubes required

2) Outside diameter of tube

3) Tube thickness or thickness required under root of fin

4) Length of finned tube

5) Number of fins per inch

6) Unfinned ends

7) Skipped portions and dimensions from one end

8) Material of tube Technical drawing of integrally finned tube by low finning

In specifying U-tubes you should advise:

1) Tube diameter, thickness and material EXTRA FOTO DOORSNEDE

2) Straight leg length

3) Centre line radius (or diameter) and number off per row

4) Whether post bend heat treatment is required

5) Whether hydraulic testing is required
