ASTM A213 TP304L 3 / 8In Stainless Steel U Bend Tubing Cold Rolled For Heat Exchanger / Boiler

ASTM A213 TP304L 3 / 8In Stainless Steel U Bend Tubing Cold Rolled For Heat Exchanger / Boiler

Heat Exchanger U 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

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
