Product Description

ASTM A789/A789M ASME SA789/SA789M UNS S32760 1.4501 F55 Super Duplex Steel U Bend Tube is widely used in equipment for the oil & gas industry, on offshore platforms, in heat exchangers, chemical processing, pressure vessels and boilers as well as in the petrochemical industry and desalination plants, including seawater piping.


Yuhong Group as the professional manufacturer of Heat Exchanger Tube in China, currently we can provide our clients Straight Tube and U Bend Tube as well as many different types with our best quality and shortest delivery time. The customers could send us the detailed drawings, we can make different types of U Bending according to the related drawings.

UNS S32760 is a Super Duplex stainless steel equivalent to A182 F55 with a microstructure of 50:50 austenite and ferrite. The high chromium and molybdenum content of Super Duplex makes S32760 extremely resistant to uniform corrosion by both organic and inorganic acids – especially those containing chloride. The higher than average molybdenum and chromium content also gives UNS S32760 greater heat resistance quality and is also designed, as a Super Duplex alloy stainless steel, to feature high tensile & yield strength, pitting resistance, strong weldability, resistance to stress corrosion cracking, erosion & crevice corrosion and corrosion fatigue and good toughness.

Qq20200218213416

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
