1. Bare Tube Dimensions, Tolerance
1.1O.D Tolerance: ±0.8%*Out-Diameter
1.2W.T Tolerance: ± 5%*Wall-Thickness
1.3Straightness : Tubes be straight with a max deviation of 0.1 in. (2.5mm) in any 10ft. (3m) section.
2.Tolerance, Requirment of Fin
2.1Fin Spacing: The number of fins per unit length of tube shall be as specified, ±2 percent, measured over at least 12 inches of welded fins.
2.2Inclination: The fin is welded 90 degrees to the tube surface. Inclination of the fin will not exceed 5 degrees from the vertical for fin heights.
3.Finished Finned Tube Tolerance
3.1Stainless Tolerance: Finished finned tubes will be straight with a maximum deviation of 0.2 in. (5mm) in any 10 ft. (3.0 m) section
3.2Length Tolerance
Length ≤ 500mm , +2mm
500mm <Length ≤ 2000mm, +3mm
2000mm <Length≤ 5000mm, +5mm
5000mm < Length≤ 7000mm, +10mm
4. Fin-to-Tube Weld Requirements
4.1Weld Width: The average width of the weld bond between the fin and the tube shall be a
minimum of 90 percent.
4.2Weld Bond: During production, the weld bond on every fifth tube will be tested by removing one wrap of fin from the trailing end of the tube. The fractured surface of the fin-to-tube weld shall be visually inspected, and the arithmetic average width of the weld bond as evidenced by the white metal exposed shall be no less than 90 percent of the measured fin thickness. If the arithmetic average width of weld bond is less than 90 percent, the weld bond of the previously finned tube will be checked, (back to the previously inspected 5th
tube, if necessary), until weld bond that averages 90 percent is found. In the event of disagreement on the visual inspection, a tensile test of the fin-to-tube weld on a representative sample yielding the minimum average values, based on the measured fin thickness, shall be considered evidence of an acceptable weld.
Fin tube heat transfer area is 8 times than the light tube, high efficiency heat exchanger, more advanced than the other heat exchanger products.
