In the oil and gas industry, flanges are key metal connectors used to connect pipes, valves, equipment, and other components.
They are typically forged or cast, and the materials are mostly corrosion-resistant and impact-resistant alloy steel or cast iron. Their main function is to achieve a detachable connection and ensure a tight seal. Here’s a detailed explanation:
Flanges connect pipes, valves, equipment, and other components through peripheral bolt holes and a gasket. They possess structural stability and sealing performance, making them particularly suitable for high-pressure, flammable, explosive, or toxic media transportation environments.
Common Types:
Slip-on Flange: Simple structure, low cost, but relatively poor rigidity; suitable for low-pressure systems.
Butt-welded flange:High rigidity, good sealing performance; suitable for high-pressure or high-temperature environments.
Threaded flange: Connected by threads; suitable for small-diameter pipes.
Materials and Processes:
Materials: Carbon steel, stainless steel, alloys, etc., selection depends on the characteristics of the medium.
Processes: Forging, casting, etc. For welded flanges, ensure material density and pass inspection. Application Scenarios
Oil pipelines: Subject to high pressure, requiring flanges to ensure sealing and prevent leakage.
Natural gas pipelines: Require flanges to withstand low-temperature, high-pressure environments to ensure long-term stable operation.
Equipment interfaces: Such as pressure reducing valves, steam turbines, etc., flanges must withstand vibration and pressure.
