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

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
