Finned Tube

We are engaged in manufacturing and supplying various types of finned tubes and finned coils for industry like G type finned tubes, L type finned tubes, crimped type finned tubes, integral finned tube, plain wire wound finned tubes, spiral wound finned tube.

G Type Finned Tube

G Type Finned Tube Diagram G Type Finned Tube
(Embedded Fin)The fin strip is wound into a machined groove and securely locked into place by back filling with base tube material. This ensures that maximum heat transfer is maintained at high tube metal temperatures. Maximum operating temperature for this fin type is 450°C. We are engaged in manufacturing of copper finned tube, steel finned tube fir various pharmaceutical industry, chemical industry, marine industry etc.

Fin material : Aluminium or copper
Tube materials : Carbon steel, Cr.-Mo. steel, stainless steel, copper, copper alloys, etc.

L Type Finned Tube

L Type Finned Tube Diagram L Type Finned Tube
The strip material is subjected to controlled deformation under tension giving the optimum contact pressure of the foot of the fin onto the base tube thus maximising the heat transfer properties. The foot of the fin considerably enhances the corrosion protection of the base tube. Maximum operating temperature for this fin type is 150°C.

Fin material : Aluminium or copper
Tube materials : No theoretical limits

KL Type Finned Tube

KL Type Finned Tube Diagram KL Type Finned Tube
Manufactured exactly as the 'L' fin except that the base tube is knurled before application of the fin foot. After application the fin foot is knurled into the corresponding knurling on the base tube thereby enhancing the bond between the fin and tube resulting in improved heat transfer characteristics. Maximum operating temperature for this fin type is 260°C.

Fin material : Aluminium or copper
Tube materials : No theoretical limits

Semi Crimped Fin

Semi Crimped Fin Diagram Semi Crimped Fin
This fin type is a non taper fin wrapped under tension around the base tube. The finning process results in a crimp forming at the foot of the fin. Fin is then welded to the base tube at the strip ends. Maximum operating temperature for this fin type is 250°C.

Fin material : Carbon/stainless steel or copper
Tube materials : Carbon/stainless steel or copper and copper alloys
