Annealed & Pickled Straight Heat Exchanger Tube ASTM A213 / ASTM SA213 TP316L / S31603

ASTM A213 / ASTM SA213 TP316L/ S31603 Annealed & Pickled Straight Heat Exchanger Tube

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 .

ASTM A213 / A213M Chemical Composition :

Application

a) For fluid & gas transport

b) Structure & machining etc

Advantages

a) Advanced technology of cold draw machine

b) Advanced annealing machine

c) Better mechanical property

d) More precise dimension

e) Perfect inspection method and inspection equipment 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
