ASTM A213 TP316 Stainless Steel Straight Heat Exchange Tube For Chemical Equipment

   Our heat exchanger tube with pickling and annealing surface is very popular in boilers and heat exchangers industry , water heater industry , air-conditioning industry etc . This kind of seamless tubes are have a very important position in our all products .

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

Stainless Steel 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
