Square or Rectangular Fins are welded on two steel base tubes. We call it Double H (HH) fin type. The surface of the fin is outside-red oxide zinc phosphate primer and inside volatile corrosion inhibitor (VCI) in water soluble tablet form. And all of them are assured by hydrostatic or pneumatic tests, eddy current tests and tensile tests in order to verify the mechanical bonding between inner tubes and outer fins. The delivery condition of this fin are ends square cut, free burrs, internally dried and air blown clean, externally coated with varnish at both ends of Square or Rectangualr Fin Tube. Besides, we provide additional services such as Tube swaging, elbows, bends (90° / 180° or as per client's design).
