Nickel-based alloy flange forgings, high-performance key accessories
Nickel-based alloy flange forgings are made of high nickel alloy forging molding and precision machining of high-performance sealing and connecting parts, widely used in petroleum, chemical, electric power, aerospace and other fields, is to ensure that the equipment is high temperature, high pressure, corrosive media transmission of the key accessories.
According to different chemical compositions, nickel-based alloy flange forgings can be divided into Hastelloy series, Inconel series, Monel series. Among them, Hastelloy series such as C-276, C-22, B-2 contains nickel, chromium, molybdenum and other elements, has excellent corrosion resistance and high-temperature strength, can be used for a variety of strong corrosive media transport, Inconel series such as 600, 601, 625 to nickel, chromium-based, good high-temperature performance and resistance to oxidation and corrosion, Monel series such as K-500 nickel, copper-based, seawater resistance and corrosion resistance. Monel series such as K-500 are mainly made of nickel and copper, with excellent seawater corrosion resistance and long service life.
These alloy flanges have nominal pressure ratings of 150LB to 2500LB, pipe diameters ranging from 1/2 inch to 100 inches, operating temperatures of up to 1000°C, and some products in specific media operating temperatures of up to 1260°C. The nickel-based alloy flanges are characterized by high temperature performance and good oxidation corrosion resistance.
Nickel-based alloy flange forgings have the following main advantages.
1. high temperature and high pressure resistant: the alloy composition makes it has good high temperature strength and creep resistance, can work for a long time in 600-1000°C high temperature conditions. 2. superior corrosion resistance: the alloy composition makes it has good high temperature strength and creep resistance, can work for a long time in the 600-1000°C high temperature conditions.
2. excellent corrosion resistance: such as Hastelloy C-276 on strong acids such as sulfuric acid, hydrochloric acid, hydrofluoric acid and alkaline solutions have excellent corrosion resistance. 3. good sealing: Hastelloy C-276 has good corrosion resistance.
3. Good sealing: precision machining and surface treatment make the flange sealing performance is excellent, low leakage rate.
4. Long service life: the alloy composition and stable microstructure make it have a long service life even under harsh working conditions.
5. Easy processing: these alloys have a certain degree of ductility and toughness, convenient for machining, welding, etc..
Due to the above excellent performance, nickel-based alloy flange forgings have been widely used in petrochemical, electric power, marine engineering and other industries, is to ensure the safe and stable operation of industrial production equipment, one of the key components. In the future, with the development of new nickel-based alloys with both high performance and environmental protection, the application of nickel-based alloy flange forgings will be more extensive.
