Corrugated Finned Tube VS Extruded Finned Tubes

Corrugated Finned Tubes: These tubes feature helical channels across their surface, providing maximum heat transfer area. They can be constructed using stainless steel, copper, or carbon steel materials. 

Extruded Finned Tubes: Manufactured through an extrusion process, these tubes come in various types such as aluminum finned tubes and mono-finned copper tubes, effectively utilized in our heat exchangers.

High Frequency Serrated Finned Tubes: Specifically designed for high-temperature applications, these tubes employ high-frequency serrations.

Integral Low Finned Tube-Mono Finned Tube: Fins are produced directly on the bare tube, utilizing the bare tubes thickness as the fin material.

Plate Type Fins: These fins, available in copper and aluminum, require tube expansion for optimal heat transfer.

Spiral Finned Tubes: Suitable for round or elliptical shapes in our heat exchangers, these tubes can be made from different materials based on customer preferences.

Stamped Finned Tubes: Stamped fins are crafted in our shop using special molds.

Tube Bending: U tubes can be bent in our shop to meet specific requirements.

Wire Wound Finned Tubes: These tubes feature spiral-wound wire on bare tubes, commonly used in turbulators and compressors.

Heat Treatment: Stress relief annealing of U-tubes after bending is applied for all positions with a radius ≤ 100 mm.

Surface Condition: Finished U-tubes must be free of scale and scratches after bending.

Dimensional Tolerances: U-tubes conform to TEMA R.C.B. standards with specific tolerances for length, flattening, wall thickness, and radius.

U-Tube Ends: Plain ends, vertically cut to the tube axis.

Repairs by welding are prohibited.
