Understanding Flange Plate
2025-12-08
A flange plate is a disc-shaped metal component used for detachable connections of pipes, valves, equipment, etc. It achieves sealing and fixation by cooperating with bolt holes and sealing gaskets.
Structure and Function
The flange is composed of bolt holes, sealing gaskets and connection surfaces. It achieves a sealing effect through bolt tightening. Its core functions include:
Sealing property: When tightening the bolts, the gasket deforms to fill the gap on the sealing surface, preventing the leakage of media (such as water, steam, chemicals, etc.);
Disassembly ease: Facilitates equipment maintenance and repair, suitable for high-pressure, high-temperature or corrosive environments;
Structural stability: Supports high-pressure scenarios (up to 42 MPa), commonly found in industrial fields such as petrochemicals, power, and ships.
Typical application scenarios:
Industrial pipeline system: Connecting valves, pumps, reactors and other equipment to ensure the safety of medium transportation;
Energy sector: Oil and gas pipelines, nuclear power cooling systems, power plant steam pipelines;
Mechanical equipment: Reducer, boiler pressure vessels, pressure vessels, etc.;
Automotive industry: Used for wheel connection to enhance driving stability.
