Фланец из нержавеющей стали
Дуплекс 2205 Фланцы из нержавеющей стали are precision-engineered flanges made from a duplex stainless steel alloy consisting of approximately 22% хром, 5% никель, и 3% молибден. This unique composition provides outstanding resistance to pitting, щелевая коррозия, and chloride-induced stress corrosion cracking. Compared to standard austenitic stainless steels like 316L, Дуплекс 2205 offers roughly twice the yield strength, allowing for lighter designs without compromising performance.
These flanges are available in various types such as weld neck, без шнуровки, слепой, раструбная сварка, коленный сустав, and threaded configurations to meet different piping system requirements. They are commonly used in offshore oil and gas platforms, chemical and petrochemical plants, опреснительные установки, сосуды под давлением, and marine environments where both high mechanical strength and corrosion resistance are critical.

Possible Alternative Grades in Place of 2205 SS Duplex Flange
904л | Better formability is needed, with similar corrosion resistance and lower strength. |
UR52N+ | High resistance to corrosion is required, e.g. resistance to higher temperature seawater. |
6%Мо | Higher corrosion resistance is required, but with lower strength and better formability. |
