Approved drawing and the delivery conditions (TDC) of clients.
Additional Services
Tube swaging, elbows, bends (90° / 180° or as per client's design).
Quality Tests
The Square or Rectangualr H Finned Tube quality is 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.
Surface Coating
Outside-Red oxide zinc phosphate primer and inside volatile
corrosion inhibitor (VCI) in water soluble tablet form.
Delivery Condition: Tube ends are square cut, free burrs, internally dried and air
blown clean, externally coated with varnish at both ends of Square
or Rectangualr Fin Tube.
