Product Description

ASTM A269 / ASME SA269 Small Diameter 1.4306 / 1.4404 Stainless Steel Heat Exchanger Welded Tube

 

 

 

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
