Nickle Alloy Flange, also known as a flange rim or flange, is a part that connects pipes to each other at the ends, and it is also used on equipment inlets and outlets for connecting two pieces of equipment, such as a reducer flange. A flange connection or flange joint refers to a detachable connection consisting of a flange, gasket, and bolt, which together form a combined sealing structure.

Categories & Application:

• Flanges are divided into threaded (screwed) flanges, welded flanges, and clip-on flanges.
• Flanges are always used in pairs; low-pressure pipes can use threaded flanges, while those operating at pressures above four kilograms use welded flanges.
• Between two flange plates, a sealing gasket is added, which is then secured with bolts. Flanges of different pressures have different thicknesses and use different bolts.
• For equipment such as water pumps and valves, when connecting to pipes, these parts of the equipment are also made into corresponding flange shapes, which are also referred to as flange connections.
• Generally, any parts that are connected by bolts on two plane perimeters and are sealed at the same time are called “flanges,” such as the connections in ventilation pipes.
• These types of parts can be referred to as “flange components.” However, this connection only constitutes a part of the equipment; for example, the connection between a flange and a water pump would not justify calling the water pump a “flange component.” Smaller items, such as valves, can be called “flange components.”
• Reducer flanges are used for the connection between a motor and a reducer, as well as for the connection between the reducer and other equipment. 
• Pipe flanges refer to the flanges used for pipe fitting in pipeline installations, and when used on equipment, they refer to the inlet and outlet flanges of the equipment. Flanges have holes through which bolts pass to tightly connect two flanges.

INCONEL ALLOY X-750 (UNS N07750/W. Nr. 2.4669) is a precipitation-hardenable nickel-chromium alloy used for its corrosion and oxidation resistance and high strength at temperatures to 1300°F. Although much of the effect of precipitation hardening is lost with increasing temperature over 1300°F, heat-treated material has useful strength up to 1800°F. Alloy X-750
also has excellent properties down to cryogenic termperatures.

Typical Applications:

The economics of INCONEL alloy X-750 coupled with its availability in all standard mill forms has resulted in applications in a wide variety of industrial fields. In gas turbines, it is used for rotor blades and wheels, bolts, and other structural members. INCONEL alloy X-750 is used extensively in rocket-engine thrust chambers. Airframe applications include thrust reversers and hot-air ducting systems. Large pressure vessels are formed from INCONEL alloy X-750. Other applications are heat-treating fixtures, forming tools, extrusion dies, and test machine grips. For springs and fasteners, INCONEL alloy X-750 is used from sub-zero to 1200°F.

Heat Treatment:

Depending on the application and the properties desired, various heat treatments are employed. For service above 1100°F, particularly where loads are to be sustained for long times, optimum properties are achieved by solution treating (2100°F) plus stabilization treating (1550°F) plus precipitation treating (1300°F). For service below 1100°F, the alloy may be strengthened by precipitation treating after hot or cold working or by precipitation treating after equalizing or solution treating. A furnace-cooling treatment is also used to develop optimum properties for some applications. The various heat treatments and the properties
developed are described under the section on Mechanical Properties.
