25.4 X 2.11mm TP347/321H Seamless U Bend Tube For Petroleum Refining,

25.4 X 2.11mm TP347/321H Seamless U Bend Tube For Petroleum Refining


Heat Exchanger Tube Process :


1 . We use Cold Drawn 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
