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
