A Slip-On Flange is a type of flange that is designed to slide over the end of a pipe. It is typically welded both inside and outside to provide a strong connection. This design allows for easy alignment and installation, making it a popular choice in various piping systems. These flanges are commonly used in industries such as oil and gas, water treatment, and chemical processing. They are compatible with different materials, including carbon steel, stainless steel, and PVC, and are available in various sizes and pressure ratings to suit specific applications.
