Product Description
A106 Gr.B SMLS Carbon Steel Tube , Helical Welded Solid Type Fin Tubes
Carbon Steel Single Row Flat Fin Tubes 0.5mm - 1.5mm
ASTM A106/A106M : Seamless Carbon Steel Pipe for High-Temperature Service
Detail:
General HF welding production capacity | General specifications of HF welding fin tube |
Welding Facility: 4 finning machines; | Tube OD: 19mm min. |
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.
Acceptance Criteria:
INTERNATIONAL STANDARD FOR DIMENSIONS, TOLERANCES, AND TESTS OF HIGH FREQUENCY RESISTANCE WELDED FINS or the delivery conditions (TDC) of clients.
Visual check:
Un-welded parts of fin, fin damage after fining, copper pollution, tears, wrap etc…
Dimensional check:
Fin height, fin spacing, fin inclination, fin corrugation, length of finned & un-finned portion etc…
Bending check:
Ovality, thickness and area reduction.
Surface Coating:
outside-Red oxide zinc phosphate primer and inside volatile corrosion inhibitor (VCI) in water soluble tablet form.
Tube End Finish:
Bevel @ (30°~35°)
Bevel Root Size
0.5mm~1.5mm
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.
Documentation:
It 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.

Competitive Advantage:
- We have more than 10,000 square meters workshop, including 4 ERW high Frequency welding fining lines, daily production capacity around 40 Tons;
- Our quality assurance plan for High Frequency Welding Spiral Steel Tubes. (2.1) Raw material control for both plain tubes and fins. (2.2) In process control with reports,as WPS, PQR&WPQ; weld deposition efficiency test before fabrication, Non-destructive test and tensile test etc. (2.3) Final inspection control with reports (Visual and dimensional check etc…).
- The High Frequency Resistance Welded Fin Tube is integrally extended for the max surface area to achieve efficiency. The heat transfer ratio of high frequency welding fin tube is about 8~9 times higher than other plain tubes.
- This Welded Helical Fin Tubes is a singular integral unit, eliminating heat contact resistance and losses. Generally tube side temperature up to 800 degree for stainess steel fins; Low carbon steels, withstanding up to 475 degree is the most common choice.
