Nickel flange, also called nickel flange flanged disk or flange. It is also used a lot by many industrial companies in Nickel Machining Parts, and is as widely used as the Titanium Flange. Nickel Flange is a part of shaft to shaft interconnection, used in the connection between pipe ends; also used in equipment inlet and outlet flange, used in the connection between two equipment, such as reducer flange. Flange connection or flange joint, refers to the detachable connection by the flange, gasket and bolt three interconnected as a group of combined sealing structure. Piping flange refers to the piping device in the piping flange, used in equipment refers to the import and export of equipment flange. There are holes on the flange, and the bolts make the two flanges tightly connected. The flanges are sealed with gaskets. Flanges are divided into threaded flanges, welded flanges and clamping flanges. Flanges are used in pairs, low-pressure pipelines can use the wire connection flange, four kilograms of pressure above the use of welded flanges.
A gasket is added between the two flanges, which are then bolted together. Different pressure flange thickness is different, they use different bolts. Water pumps and valves, in connection with the pipeline, the localization of these devices and equipment, but also made of the corresponding flange shape, also known as flange connection. Where the two planes around the use of bolts to connect the connection parts closed at the same time, generally known as the “flange”, such as ventilation pipe connection, this type of parts can be called “flange parts”. But this connection is only a local equipment, such as flange and pump connection, it is not good to call the pump “flange parts”. Comparatively small such as valves, etc., can be called “flange parts”.
Physical and chemical properties of nickel:
Nickel is a silvery-white ferromagnetic metal that is a major component of many magnetic materials.
Nickel also has good oxidation resistance and strong corrosion resistance.
Nickel is a silvery-white ferromagnetic metal. Density 8.9 g/cm3, melting point 1455 ℃.
Nickel has magnetic properties and is the main component of many magnetic materials.
Nickel Material also has good oxidation resistance. In air, NiO film is formed on the surface of nickel, which prevents further oxidation. Experiments have proved that: nickel with a purity of 99% will not develop rust marks within 20 years. Nickel's corrosion resistance is very strong, especially for caustic alkali corrosion resistance, in 50% of boiling caustic soda solution nickel corrosion rate of no more than 25 microns per year.
Nickel's strength and plasticity is also very good, can withstand a variety of pressure processing.
Because nickel flange has good comprehensive performance, it is widely used in chemical industry, construction, water supply, drainage, petroleum, light and heavy industry, refrigeration, sanitation, plumbing, fire fighting, electric power, aerospace, shipbuilding and other basic engineering.
