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 positions or as customers 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
