A106 Gr.B SMLS Carbon Steel Tube , Helical Welded Solid Type Fin Tubes

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;
Daily production capacity up to 40 tons;
HFW Fin type: solid plain and serrated.

 Tube OD: 19mm min.
 Tube Length: 18 meters max.
 Fin Height: 32 mm max.
 Fin Thickness: 0.8mm min
 Fin Pitch: min. 4 mm for solid fins & 3.3mm for serrated fins.

 
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.
