Heat Exchange Tube Application :

a) Petroleum , chemical enterprise , super heater of boiler and heat exchanger
b) High temperature-resistant transmission fluid pipe in power station
c) Ship with pressure pipe
d) Exhaust purification device
e) Construction and ornament
f) solar industry , military , semiconductor etc

Heat Exchange Tube Production 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
