S30403 / S31603 1 / 4 Inch Heat Exchanger Tube , Stainless Steel U Bend Welded Tube

S30403 / S31603 1 / 4 Inch Stainless Steel U Bend Heat Exchanger Welded Tube

Process :

1 . We use Cold Drawn techonology 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
