What is flange, it is the pipe and pipe between the interconnected parts, used for the connection between the pipe end
Connection: also used in equipment inlet and outlet flange, used for the connection between two equipment.
Flanges are commonly used to connect pipes, two pipes to be connected, they can be directly welded together, but in this way very laborious, and difficult to maintain, when the pipeline and the net door need to be connected, straight welding together, the same laborious, and maintenance is not
Then. The introduction of flange, can be convenient to solve the above problems.
The pipe is welded on the flange first, and the male door and other devices are also equipped with flanges. When connecting, the flanges and flanges are combined in -
The flange end piece is attached in the middle, and the two are connected together through the flange screw, which is convenient and labor-saving. Maintenance, only
Run and remove the screws from the flanges. You can remove the pipes or doors from the flanges and repair or replace them
And the valve.
Flange has a hole limit, bolts make two flange purple. The flanges are sealed with fabric. According to the flange connection mode, flange
