The production process of flange nut:

1. Material Selection: Select the suitable material according to the required strength and environmental conditions.

2. Cutting: Cut the material into the required shape and size.

3. Cold heading : the basic shape of the flange nut is created by applying pressure to the material at room temperature using a mould.

4. Threading: Creating precise threads to ensure a firm fastening.

5. Heat Treatment: Increase the hardness of the nut and adjust the toughness of the nut.

6. surface treatment: applying anti-corrosion coating.

7. Quality Inspection: Ensure that each nut meets strict quality standards.

8. Packaging: Packaging the finished nuts for shipment.

Global standards for flange nuts:

Manufactured and used around the world, flange nuts adhere to various international standards to ensure compatibility and performance. Key standards include:

- ISO (International Organisation for Standardisation): ISO 898-1 provides guidance on dimensions, materials and mechanical properties to ensure global compatibility.

- DIN (German Standards Institute): DIN 787 outlines specifications for flange nuts used in Europe, focusing on dimensional and material requirements.

- ANSI (American National Standards Institute): ANSI/ASME B18.2.1 specifies the North American standard for flange nuts, detailing size and shape requirements.

- JIS (Japanese Industrial Standards): JIS B 1180 defines characteristics and test methods for Japanese flange nuts to ensure quality and performance.

Common pairs of flange nuts:

Flange nuts are usually paired with various fasteners to ensure a safe and reliable connection:

- Bolt: The most important pairing of flange nuts is the bolt. The flange nut is screwed onto the bolt by rotation.

- Flanges: In pipe connection scenarios, flange nuts are often paired with flanges. The sealing gasket between the flanges is squeezed by tightening the nut, resulting in a hermetically sealed pipeline connection.

- Gasket: Sometimes a flange nut is used in conjunction with a gasket. Gaskets are usually placed between the flanges or between the nut and the connecting parts and are made of various materials such as rubber, asbestos, and so on.
