Lord Fin Tube-Corrugated Finned Tube & Extruded Finned Tubes

Corrugated Finned Tube: There are helical channels overall the tubes to supply maximum heat transfer area. Stainless steel, copper and carbon steel materials can be used. Extruded Finned Tubes: These tubes are manufactured by extrusion process. Different kinds of these tubes as aluminium finned tubes, mono-finned copper tubes are successfully used in our heat-exchangers.
High Frequency Serrated Finned Tubes: High frequency serrated finned tubes are used at high temperatures. 
Integral Low Finned Tube-Mono Finned Tube: These fins are produced on the bare tube. The thickness of the bare tube is used as a fin material. 
Plate Type Fins: These kinds of fins can be manufactured as copper and aluminium. Tubes must be expanded to supply maximum heat transfer. 
Spiral Finned Tubes: Spiral finned tubes can be used in our heat exchangers as round or eliptical shapes. Different materials may be used as fin and tube material according to our customer needs. 
Stamped Finned Tubes: Stamped fins can be manufactured in our shop by our special molds. 
Tube Bending: U tubes can be bended in our shop. 
Wire Wound Finned Tubes: Wire is spiral wounded on bare tubes. These kinds finned tubes are usually used for turbulators and compressors.
Heat treatment 
Stress relive annealing of U-tubes after bending – only for all positions with radius ≤ 100 mm
Surface condition Finished U-tubes shall be free of scale, without scratches after bending.
Dimensional tolerances U-tubes acc. to TEMA R.C.B.
Length of straight part -0/+5 mm
Flattening (also called "ovality") at the bend shall not exceed 10% of the nominal tube outside diameter.
Wall thickness in bending part acc. to TEMA RCB 2.31
Minimum tube wall thickness in the bend part (Tmin)
T(min) ≥ (SW × (2×R + D))/( 2× (R+D)
Where:    SW             is smallest wall thickness
     D                Nominal outside diameter
     R                 radius
Radius tolerance  1) for R ≤ 100 mm +/- 3 mm
         2) for R ≥ 100 mm +/- 5 mm
Straightness tolerance max. 1.5 mm per 1000 mm
U-Tube ends: plain, vertically cut to the tube axis
