Welding neck flanges feature a long tapered hub that provides smooth stress distribution and strong structural integrity. They are commonly used in high-pressure and high-temperature pipeline systems.
Slip on flanges are easy to install by slipping the pipe into the flange bore and welding it in place. They are widely used in low-pressure applications where easy alignment is required.
Blind flanges are used to close the end of a piping system or pressure vessel. They provide easy access for inspection and maintenance and are suitable for various pressure ratings.
Threaded flanges are designed with internal threads and can be installed without welding. They are typically used in low-pressure and non-critical piping systems.
Socket weld flanges are designed for small-diameter, high-pressure piping. The pipe is inserted into the socket and welded, providing a strong and leak-resistant connection.
Orifice flanges are used together with orifice plates to measure flow rate in piping systems. They are commonly applied in oil, gas and chemical industries.
Spectacle blinds consist of a solid plate and a spacer connected by a web. They are used to isolate sections of a pipeline for safety and maintenance purposes.
Anchor flanges are designed to restrict axial movement in pipeline systems. They are commonly used in long-distance pipelines and high-pressure applications to absorb thrust forces.
