Duplex stainless steel pipe fittings with 316 l and 317 l austenitic stainless steel pipe fittings, duplex stainless steel 2205 in the resistance to pitting spots and cracks Much better, it has a high resistance to decay, and austenite match, its lower coefficient of thermal contraction, higher thermal conductivity.
Use the categories:
Pressure vessel, high pressure storage tank, high-pressure pipe, heat exchange device (chemical processing industry).
Oil and natural gas pipe, heat exchange pipe fittings such as seawater resistance to low temperature heat exchange device of nitric acid and condenser and accessories.
Secondary characteristics: high strength, excellent impact toughness and excellent the whole and partial stress decay resistance ability.
Useful, for example: consumer soda with water heat exchange device and refinery hydrocracking air cooler, refinery distillate of the tower.
