ASTM A269/ A213 317 / 347 / 347H seamless stainless steel U bend heat exchanger tube for oil industry
317 / 347 / 347H U bend tubes manufacturer, 317 / 347 / 347H stainless steel U shaped tubes exporter,ASTM a213 317 / 347 / 347H u bend tubes stockholder ,317 / 347 / 347H stainless steel heat exchanger tubes for heat exchanger tube supplier in china
it is widely used in light industry,heavy industry,daily necessities and the decoration industry.my company long-term supply ASTM A269/ A213 317 / 347 / 347H seamless stainless steel U bend heat exchanger tube for oil industry, products including:stainless steel sheet,stainless steel coil and stainless steel 317 / 347 / 347H U bending tube. stainless steel u tube for heat exchanger tubes for oil industry
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
