Heat Exchanger Length 18000mm TP409 Stainless Steel Square Pipe
10# , 20# , 16Mn , 20G , 12Cr1MoVG 'H Fin' ’HH Fin' Welded Heat Exchanger Tubes
Description:
Square or Rectangular H Fins are welded on a steel base tube. We call it H Fin Type Tubing. About this fin we provide additional services like Tube swaging, elbows, bends (90° / 180° or as per client's design). It has various uses in Economizers ,Heat exchangers, Marine boilers
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.
Acceptance Criteria
Approved drawing and the delivery conditions (TDC) of clients.
Surface Coating
Outside-Red oxide zinc phosphate primer and inside volatile corrosion inhibitor (VCI) in water soluble tablet form.
