High strength twelve corner flange bolts provide better torque transmission and smaller installation space through their twelve corners (i.e. hexagonal heads), which makes them have high strength and reliability when connecting and sealing flanges. This design allows for the use of twelve corner sleeves for fastening in narrow spaces, and high strength means they can withstand greater loads.
effect
Flange connection: As high-strength connectors, they are used to connect flanges (such as pipes, equipment inlet and outlet flanges) and form detachable sealed connections with nuts.
Load bearing and fastening: They can withstand large axial and radial loads, providing strong fastening force to ensure the sealing and stability of flange connections.
Applied in high-pressure environments: Due to its high strength rating, especially in high-pressure or high-temperature applications, the twelve corner flange bolt can ensure the reliability of the connection.
advantage
Higher torque transmission: The twelve corner head design provides better torque transmission than the traditional hexagonal head design, as it allows for the use of smaller and thinner sleeves at the same size.
More compact installation space: The twelve corner head has an advantage in situations where rotation space is limited, as it can be tightened or loosened with a smaller rotation angle.
High strength: They are usually made of materials such as alloy steel and undergo heat treatment (quenching, tempering) to have a high strength grade (such as 8.8 or higher), which can resist greater stress.
Reliable sealing: As a key component of flange connections, they form a reliable sealing structure together with flanges and gaskets to prevent medium leakage.
