Stainless Steel 310 and 310S Flanges are high-chromium nickel alloys known for their exceptional corrosion resistance and heat resistance properties. These alloys are widely used in various industries, including petrochemical, chemical, and aerospace, due to their excellent performance in high-temperature environments.
Flanges play a crucial role in connecting pipes, valves, and other equipment in a piping system. Stainless Steel 310S Flanges are specifically designed to meet the demanding requirements of applications involving elevated temperatures and corrosive environments.
Types of Flanges:
Weld Neck Flanges: These SS 310S flanges are designed to be butt-welded to the piping system, providing excellent strength and reliability.
Slip-On Flanges: These flanges are slipped over the pipe and then welded in place, offering easy installation and lower costs.
Blind Flanges: Used to close the end of pipes, valves, or equipment openings, blind flanges are essential for isolating sections of a piping system.
Threaded Flanges: These flanges have threaded holes, allowing them to be connected to threaded pipes or fittings without welding.
Socket Weld Flanges: Designed for use with small-diameter pipes, socket weld flanges are ideal for systems requiring frequent disassembly.
