Heat Exchange TubeProcess :
We use Cold Drawn techonology to produce U bend tube
U bend tubes produce will accordance to customer's drawings
To avoid oxidation , inert gas (Argon) is passed through tubes ID at the required flow rate
The radius is checked for its OD and wall thinning with the recommended specification
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
Visual inspection for waviness and cracks is done with Dye Penetrant Test
Each tube is then hydro tested at the recommended pressure to check for leakage
