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
