Introduction
Pipeline flanges are essential components used to connect pipes, valves, and fittings in industrial pipeline systems. High-quality flanges ensure reliable sealing performance, easy installation, and safe operation under high pressure and temperature conditions.
Shaanxi Gold-Stone supplies a full range of carbon steel, stainless steel, and alloy steel flanges for oil and gas, petrochemical, LNG, power plant, and industrial pipeline applications. All flanges are manufactured according to international standards including ASME, ASTM, API, and ANSI.
Types of Pipeline Flanges
Weld Neck Flange
Weld neck flanges are designed for high-pressure and high-temperature applications. The long tapered hub provides excellent strength and reduces stress concentration.
Applications:
Oil and gas pipelines
High pressure systems
Refinery piping
Power plant pipelines
Slip On Flange
Slip on flanges are easy to install and commonly used in low to medium pressure pipelines. They are cost-effective and suitable for general industrial applications.
Applications:
Water pipelines
Low pressure systems
Industrial piping
Utility pipelines
Blind Flange
Blind flanges are used to close pipeline ends and pressure vessel openings. They provide reliable sealing and easy maintenance.
Applications:
Pipeline end closure
Pressure testing
Maintenance shutdown
Pipeline isolation
Socket Weld Flange
Socket weld flanges are suitable for small diameter high-pressure pipelines. They provide strong and leak-proof connections.
Applications:
High pressure pipelines
Small diameter piping
Chemical plants
Hydraulic systems
Threaded Flange
Threaded flanges are used in low-pressure systems where welding is not allowed. They are easy to install and remove.
Applications:
Low pressure pipelines
Utility systems
Water pipelines
Compressed air systems
