ASTM A213/ASME SA213 TP316L(1.4404) Seamless U Bending Tube for Heat Exhcanger

ASTM A213/ASME SA213 TP316L 1.4401 1.4404 Stainless Steel U Bend Heat Exchanger Tube With High Strength For Oil & Gas Application

At present U Bend Tube are widely used in Heat Exchanger Systems. Heat-Exchanger Equipments on the basis of Seamless Stainless U-Tubes and Welded Stainless U bend Tube is essential in strategically important and critical felds---Nuclear And Petrochemical Machine Building. Yuhong Group start to produce U Bend Heat Exchanger Tube Since 2006, now every year we can supply more than 6000 tons of Stainless Steel U Bend Tubes to 50 countries in the world.

Chemical Composition

Process :

1 . We use Cold Rolled and Cold Drawn techonology to produce U bend tube

2 . U bend tube produce will in accordance with the 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 positions or as customer's request to make sure of the tubes quality. We'll test mechnical properties and micro-structure tests
6 . Visual inspection for witness and cracks will be done with Dye Penetrant Test
7 . Each tube shall be done Eddy current test and Hydrostatic test at the recommended pressure to check for leakage

Below quality tests will be carried out by us:
