Cold Rolled Nickel Alloy Heat Exchange Seamless U Tube With Annealed



Heat Exchange Tube Process :

1 . We use Cold Drawn/cold rolled technology to produce U bend tube

2 . U bend tubes produce will accordance to customer's drawings

3 . To avoid oxidation , inert gas (Argon) is passed through tubes ID at the required flow rate

4 . The radius is checked for its OD and wall thinning with the recommended specification

5 . We'll choose three different position or as customer's require to make sure tubes quality . We'll do physical properties and micro-structure test

6 . Visual inspection for waviness and cracks is done with Dye Penetrant Test

7 . Each tube is then hydro tested at the recommended pressure to check for leakage
