Flange Bolts Overview

Its head has various shapes, and the most common one is a hexagonal head. The design of this hexagonal head is convenient for tightening with tools such as wrenches. During the installation process, the hexagonal head is clamped with a tool and tightened by rotating the bolt.

The screw part of the flange bolt generally has threads, and the specifications of the threads vary according to different application scenarios and standards. For example, there are coarse threads and fine threads. The fine thread has a smaller pitch, and under the same nominal diameter, its self-locking performance is better, and it can withstand greater tension and vibration to prevent the bolt from loosening.

Application of Flange Bolts

• Widely used in pipeline systems: Whether it is a pipeline for transporting liquids, such as oil pipelines, water supply and drainage pipelines, or a pipeline for transporting gas, such as a natural gas pipeline, flange bolts are key components for connecting flanges. It can ensure the sealing of pipeline connections and prevent liquid or gas leakage.
• It is also often used in the field of mechanical manufacturing: For example, in the shell connection of some large equipment or the part of the mechanical structure that needs to be connected by a flange, the flange bolt plays a role of fixing and connecting to ensure the overall stability and reliability of the equipment.

Feature of Flange Bolts

1. Strong corrosion resistance: Contains alloy elements such as chromium, and forms a protective film on the surface, which can resist corrosion from various media and is suitable for harsh environments, such as chemical pipeline connections.
2. Excellent mechanical properties: Various strength grades and good toughness, can be selected according to different working conditions to ensure stable connections, such as reliable flange connection in pressure-bearing equipment.
3. Convenient and beautiful installation: Convenient installation and disassembly, self-locking, and shiny appearance, used in places with requirements for appearance and maintenance, such as architectural decoration projects.
4. Good hygienic adaptability: Non-toxic and non-polluting, meets the hygienic standards of food, pharmaceutical and other industries, adapts to a variety of flange materials, and is conducive to building a connection system with different material combinations.
