Inconel flange is a nickel based alloy flange with excellent high temperature resistance and corrosion resistance, widely used in chemical, energy, aerospace and other fields. Here is a detailed introduction about it:

Common types and characteristics

Inconel 600 flange: It has good corrosion resistance and heat resistance, and can maintain stable performance in low to high temperature environments. It is not easy to crack or tear, and is suitable for low-temperature industries such as refrigeration and occasions that require heat resistance. Its implementation standards include ASTM B564, and there are various flange types such as SO, SW, BL, etc. The size range is 1/2 "-48", DN10-DN4000.

Inconel 800 flange: It has the ability to resist oxidation, carburizing, and sulfurization, as well as good thermal fatigue resistance. Commonly used in high-temperature equipment such as heat exchangers, process pipelines, and steam generators in the chemical and petrochemical industries, as well as power plants.

Inconel X-750 flange: It is a nickel chromium based high-temperature alloy flange that can maintain excellent mechanical properties at high temperatures ranging from 704 ° C to 982 ° C through solution strengthening and precipitation hardening treatment. It has high tensile strength, creep resistance, and excellent corrosion resistance, and is commonly used in high-temperature equipment such as steam generators and gas turbines in nuclear power plants.

Inconel 725 flange: It belongs to the age hardened nickel chromium molybdenum niobium alloy flange, which combines ultra-high strength and excellent corrosion resistance. The yield strength in the age state can reach 1000MPa, and it can withstand chloride stress corrosion, seawater corrosion, and acidic medium corrosion. It is suitable for temperatures ranging from -196 ℃ to+650 ℃ and is commonly used in deep-sea oil and gas, chemical, nuclear power and other fields.

Manufacturing Standard

The manufacturing of Niccol alloy flanges usually follows standards such as ASTM, ASME, DIN, EN, JIS, etc. For example, the manufacturing standards for Inconel 600 flanges include ASTM B564, ANSI B16.5, etc., and the dimensional tolerances comply with the requirements of ASME B16.5 or EN 1092-1 standards.

Application field

Chemical and petrochemical industries: Nickel alloy flanges can resist various corrosive media and high temperature environments, and can be used in reactors, heat exchangers, pipeline connections, and other parts to ensure long-term stable operation of equipment under harsh working conditions.

Energy industry: In steam generators, gas turbines, and related equipment in power plants, Niccol alloy flanges ensure the safety and efficiency of energy production due to their excellent high-temperature performance and corrosion resistance.

Aerospace industry: Used for manufacturing components that require extreme temperature and pressure in aircraft engines, rockets, and other equipment, such as pipeline connection flanges, which help improve the safety and reliability of the equipment.

In the field of ocean engineering, Inconel 725 flanges, due to their resistance to seawater corrosion, can be used for offshore oil and gas development equipment such as underwater Christmas trees and high-pressure wellhead devices.
