Hubbed Slip-On Flanges are a type of pipe flange designed to be slipped over the pipe and welded in place for a secure and leak-proof connection. According to the EN 1092-1 standard, PN6 rated flanges are suitable for low-pressure applications (up to 6 bar). The hub provides additional strength and helps with proper alignment during installation. These flanges are commonly used in water supply, irrigation, and low-pressure industrial systems.
