ANSI/ASME B16.5 Class 1500 Slip On Flange is a slip-on flange that complies with the ANSI/ASME B16.5 standard, designed for ultra-high-pressure (Class 1500) and large-diameter piping systems. It connects to the pipe by sliding over it and is welded at the joint, making installation straightforward and cost-effective. The flange is available in sizes ranging from 1/2 inch to 12 inches and can be made from materials such as carbon steel, stainless steel, or alloy steel, depending on the application environment. It is widely used in industries like oil and gas, chemical, and power, where high-pressure systems are required.
However, the Class 1500 Slip On Flange is not recommended for extremely high-pressure or high-vibration environments. Proper welding is essential to ensure leak-proof and strong connections, and material selection must account for the corrosiveness of the medium and temperature conditions. Despite these considerations, its ease of installation and cost efficiency make it a popular choice for various industrial applications.
