Yingke Nickel Alloy Flange is a high-performance flange made of nickel based alloy, which has excellent characteristics such as high temperature resistance and corrosion resistance, and is widely used in fields such as petroleum, chemical, aerospace, etc. Here is a detailed introduction about it:

Common materials and characteristics

Inconel 625 contains approximately 58% -63% nickel, 20% -23% chromium, 8% -10% molybdenum, and other elements. Its tensile strength is ≥ 827MPa, yield strength is ≥ 414MPa, elongation is ≥ 30%, and it can maintain good mechanical properties at temperatures up to 982 ° C. It has extremely strong oxidation resistance and corrosion resistance, especially in high temperature and high pressure environments.

Inconel 718: The main components include 50% -55% nickel, 17% -21% chromium, 2.8% -3.3% molybdenum, etc. The density is 8.19g/cm ³, the melting point is between 1260 ° C-1340 ° C, the tensile strength is 965MPa-1035MPa, and the yield strength is 550MPa-725MPa. It can maintain good performance in the temperature range of -250 ° C to 700 ° C, and has good oxidation resistance and stress corrosion cracking resistance.

Inconel 800H: It is a variant of Inconel 800, containing 30% -35% nickel, 19% -23% chromium, and 39.5% lower iron. Its tensile strength can usually reach 520MPa, yield strength can reach 205MPa, and it has excellent anti-oxidation and anti carburizing properties, which can be used in environments up to 1100 ° C.

Specifications and Dimensions

Diameter range: It can be manufactured according to international standards such as ANSI, ASME, DIN, JIS, etc. The common diameter range is 1/2 "-48" (DN15-DN1200).

Pressure level: including multiple levels such as 150 # -2500 #.

Sealing surface forms: There are various forms such as RF (protruding surface), FF (full plane), RTJ (ring connection surface), etc., to meet the sealing requirements of different working conditions.

Application field

Ocean engineering: capable of withstanding corrosion from seawater, suitable for pipeline connections of deep-sea oil and gas extraction equipment.

Chemical processing: It has excellent performance in handling corrosive media such as acids, alkalis, and salts, and can be used for connecting parts of equipment such as reactors, heat exchangers, and pipelines.

Aerospace: Due to its stability at extreme temperatures, it is widely used as a pipeline connecting component in aircraft engines and missile systems.

Nuclear industry: The radiation resistance of Inconel alloy makes it an ideal material for flanges in nuclear reactors and related equipment.
