Flanges, also known as flange disks or rimshafts, are components used to connect pipes together at their ends. They feature holes that are secured with bolts, and a gasket is used to seal the joint between the flanges. Flanges are a common type of disc-shaped part in pipeline engineering and are always used in pairs. In pipeline construction, flanges are primarily used for connecting pipes. In cases where...

Flange
At the ends where two pipes are connected, install a flange on each end. Low-pressure pipes can use threaded flanges, while flanges for pressures above 4 kg should be焊接 flanges. Place a seal between the two flanges and then secure them with bolts.
Flanges of different pressures have varying thicknesses and use different bolts.
Pumps and valves, when connected to pipes, the local parts of these equipment are also shaped into corresponding flange patterns, also known as flange connections.
Components that are sealed by bolting two planes together at the periphery are generally referred to as "flanges," such as the connections in ventilation ducts. Such parts can be termed "flange-type components."
A threaded flange is a type of flange. The threaded flange connection structure is a composite component, consisting of a pair of flanges, several bolts, nuts, and a washer.
