Mock-up test for finned tube

[sevenieh]

Does anyone know codes or standards about mock-up test for finned tube in heat exchager?

or is it just made by maker's standards?

Mock-up test : number of specimen, visual inspection for the fin bonding and corrugation(the width of the weld bond between the fin and the tube, dimension(fin height, fin pitch, fin inclination), fin bend test by using screw driver, tensile test of the fin-to-tube weld, micro photo of the fin-to-tube weld to verify the bonding, etc

I have looked for it in ASTM, TEMA, ASME Sec. 8, Div. 1, API STD 610 or else.

But I can't find that.

Plz let me know.

Mock-up Test of tube-to-tubesheet joints is normally adapted to seal-welded or strangth welded joints. But it is also a good method to test tube-to-tubesheet joints for rolling or expanding tube-to-tubesheet joints. Mock-up test requirements and procedure shall get agreement between Manufacturer and Purchaser.

Referrence:
EEMUA_143 "RECOMMENDATIONS FOR TUBE END WELDING:TUBULAR HEAT TRANSFER EQUIPMENT"
BS 4870-3 "Approval testing of welding procedures —Part 3: Arc welding of tube to tube-plate joints in metallic materials"
TEMA -9th "STANDARDS OF THE TUBULAR EXCHANGER MANUFACTURERS ASSOCIATION"
ASME Section VIII Div.1 NONMANDATORY APPENDIX A "BASIS FOR ESTABLISHING ALLOWABLE LOADS FOR TUBE-TO-TUBESHEET JOINTS"
ASME Section IX, QW-193 Tube-to-Tubesheet Tests When the applicable Code Section requires the use of this paragraph for tube-to-tubesheet demonstration mockup
qualification, QW-193.1 through QW-193.1.3 shall apply.

Other Air Cooled Heat Exchanger Related Test standard:
ASME PTC 30-1991
ASME PTC30.1-2007

Thank you very much.

But I have found about tube to tubesheet mockup test, too.

I'm trying to find about mockup test for finned tube's weldability (fin to tube welding).
