Flange nut introduction

Flange nut, also known as gasket nut, spoil nut, hexagonal flange face nut or flange nut, etc., is a special fastener that is widely used in mechanical equipment and industrial piping systems to ensure the reliability and safety of machinery and equipment.

Flange nuts typically have a wide flange at one end that acts as a one-piece washer to distribute the pressure of the nut over the part being secured, reducing the potential for component damage and reducing the risk of loosening due to uneven fastening surfaces. This design also helps to provide good sealing performance, prevent leakage of fluids or gases, and ensure the proper operation of the system.

Flange nuts are mostly hexagonal in shape and are usually made of metal materials such as carbon steel, alloy steel, or stainless steel, and the surface is usually plated with zinc or other anti-corrosion materials to improve corrosion resistance. Depending on the use and specifications, there are many types of flange nuts, such as threaded flange nuts and welded flange nuts, etc. Among them, threaded flange nuts are often used to connect two flanges and the gasket between them, especially in pipeline systems; Welded flange nuts are used in conjunction with welded flanges and are suitable for heavy-duty and high-temperature piping systems.

In the production process, flange nuts go through forging, turning, heat treatment and surface treatment. Forging can improve the crystal structure of raw materials, improve the strength and wear resistance of threads; Turning is used to machine the threads and other details of the nut; Heat treatment improves the performance and microstructure of the nut through the heating and cooling process; Finally, surface treatments, such as electroplating or applying anti-corrosion coatings, enhance the corrosion resistance of the nut.

In general, flange nuts play an important role in connection and sealing with their unique structure and excellent performance, and are one of the indispensable fasteners in the industrial field.
