The use of hexagonal flange nuts in combination with washers is very common in flange connections, and this combination provides better sealing and preventing fastener loosening properties. Hexagonal flange nuts typically have a larger bottom support surface and can be used in conjunction with washers to accommodate different connection needs.

Carbon Steel: Typically used for general applications.

Stainless Steel: For environments where corrosion resistance is required.

Alloy Steels: Used in applications requiring high strength or high temperature resistance.

Advantage:

Enhanced Sealing: Gaskets provide a better seal to prevent fluid leakage. Evenly Distribute Pressure: Gaskets help to evenly distribute tightening forces between the connecting surfaces, reducing localized overpressure. Prevents loosening: Certain gasket materials (such as nylon) can provide additional friction to help prevent nuts from loosening during vibration.

Scope of Application

Pipe Connections: In the connection of pipes and flanges, the combination of hexagonal flange nuts and washers provides additional sealing and fastening. Mechanical Equipment: Used to secure and clamp components in the assembly of mechanical equipment. Chemical industry: In the chemical industry, for equipment and pipe connections that handle corrosive or toxic substances.
