SLIP ON FLANGES
SLIP ON FLANGE MANUFACTURERS | ASME/ANSI B16.5, B16.47 SERIES A & B, B16.48, BS4504, BS 10, EN-1092
A Slip-On Flange is a type of flange that is designed to slide over the pipe, with the flange face extending outward for easy welding and bolting to other equipment or piping systems. These SORF flanges are widely used in low-pressure applications where assembly efficiency and cost-effectiveness are crucial. The pipe is inserted into the flange and fillet welded at both the inner and outer sides to ensure a secure connection.
SORF Flange are easy to align during installation and require less precision in cutting the pipe length compared to other flange types. They are commonly manufactured in materials such as carbon steel, stainless steel, and alloy steel, making them suitable for various industries, including chemical, petrochemical, oil and gas, and water treatment. Their versatile design and availability in multiple sizes and pressure ratings make them a popular choice in piping systems.
