Stainless steel is one of the strongest construction metal materials, with anti-corrosion, anti-rust, wear-resistant and other characteristics.

Stainless steel flanges are highly resistant to corrosion, and chrome-containing stainless steel stamped flanges combine mechanical strength with high elongation, making parts easy to machine and manufacture to meet the needs of architects and structural designers. All metals react with oxygen in the atmosphere to form oxide films on their surfaces.

The flange gasket is to achieve the sealing effect of the flange. A gasket is a ring made of a plastically deformable material with a certain strength. Gaskets are usually cut from non-metallic sheets or manufactured to specified dimensions in specialized factories, and materials include asbestos rubber sheets, asbestos sheets, PTFE sheets, polyethylene sheets and thin metal sheets. There are also sheets (tin, stainless steel), which are metal-coated gaskets wrapped in a non-metallic material such as asbestos. According to different pressure levels, flange gaskets also have different materials, ranging from low-pressure asbestos gaskets, high-pressure asbestos gaskets, PTFE gaskets to metal gaskets.

Flange connection is to use flanges to connect the pipes or fittings to be connected, and the joints can be disassembled. The connection method is more inclusive, and can be connected with the pipe fittings by hot melt or bonded. Some pipes and fittings that are not suitable for hot melt or electrofusion connection can be connected by flange connection. For example, ppr pipe, metal pipe and other pipes are not suitable for hot melt connection. Flanged connections are easy to use and can withstand higher pressures. Flange connections are widely used in industrial pipelines.
