Continuous helical welded heat exchanger fin fube SA213-TP304H NPS 2'' X SCH80S

Quick Detail:

High Frequency Resistance Welded Helical Steel Fin Tubes is widely used in the recovery of waste heat from boiler flue gas.


General HF welding production capacity

General specifications of HF welding fin tubes

Welding Facility: 4 finning machines;
Daily production capacity up to 40 tons;
HFW Fin type: solid plain and serrated.

Tube OD : 19mm min.
Tube Length : No limit
Fin Height : 32 mm max.
Fin Thickness: 0.8mm min
Fin Pitch : min. 4 mm for solid fins

and 3.3mm for serrated fins.



General Manufacturing Process:

The fin strip is welded continuously and spirally wound onto a polished bare tube. And the tube and fins are bonded together by using high frequency resistance welding technique.
We produce both solid plain and serrated helical welded steel finned tube. And also, all spiral welding tubes could be bent in the middle or at the end of fin tubes, we call it Hairpin tubes.


Basis parameters for helical welded fin tubes:

  1. High frequency welding machine output power supply: 200KW or 300KW
  2. The High Frequency Resistance Welded Spiral Fin Tube quality is assured by hydrostatic or pneumatic tests and tensile tests in order to verify the mechanical bonding between bare tube and fin materials.
  3. Acceptance criteria: INTERNATIONAL STANDARD FOR DIMENSIONS, TOLERANCES, AND TESTS OF HIGH FREQUENCY RESISTANCE WELDED FINS or the delivery conditions (TDC) of clients.
  4. Visual check: un-welded parts of fin, fin damage after fining, copper pollution, tears, wrap etc…
  5. Dimensional check: fin height, fin spacing, fin inclination, fin corrugation, length of finned & un-finned portion etc…
  6. Bending check: ovality, thickness and area reduction.
  7. Coating: outside-Red oxide zinc phosphate primer and inside volatile corrosion inhibitor (VCI) in water soluble tablet form.
  8. Fin end finish: Bevel(30~35 degree)
  9. Delivery condition: Tube ends are square cut, free burrs, internally dried and air blown clean, externally coated with varnish at both ends of helical welded tubes. The desiccants are put into the each package for continental transportation as well.
  10. Documentation shall include QAP, WPS, PQR& WPQ, raw materials mill certificates, inspection and test samples results and warranty certificate of manufacturer.


Applications:

The High Frequency Resistance Welded Helical Fin Tubes are widely applied in fired heaters, heat exchanger, boilers, economizers, pre-heaters, coolers, heat pipes, heaters etc….


Specifications:

A wide range of fin and tube materials could be combinations are available.
