The structure of the flange nut is that there is a wide flange at one end,
which is equivalent to an integrated washer. This structure can
distribute the pressure of the nut to the fixed parts, thus reducing
the possibility of damage to the parts, and it is not easy to loosen
because the fastening surface is not uniform.
Some flange nuts are serrated, which provides any kind of locking action
and acts as an anti-loose lock. The serration of the toothed
flange nut has a special Angle, which can make the nut
rotate in the direction of the principle, so as to achieve
the locking effect, and this serration can not be used with the washer,
nor can it be used for scratched surfaces.
The detachable connection structure is often used between the cylinder
and the head, the pipe fitting and the valve of the pressure vessel to
facilitate the needs of the production process and the convenience of
manufacturing, transportation, installation and maintenance. Common
flange connection, threaded connection and socket connection. The flange
connection has the advantages of reliable sealing, sufficient strength and
wide application range.
Because the fasteners with black zinc plating have good corrosion resistance and wear resistance, they are suitable for harsh working environments, such as Marine environments and chemical equipment. In addition, black zinc plated fasteners are also commonly used in occasions requiring higher aesthetics, such as automotive, electronics and other industries.
