SORF (Slip-On Raised Face) flanges are commonly used in pipeline systems to connect pipes, valves, pumps, and other equipment. They have a raised face design, making them easier to assemble and seal with gaskets. These flanges are ideal for low- to medium-pressure applications and are commonly used in the oil and gas, chemical processing, water treatment, and HVAC industries The slip-on design facilitates portability will fit compared to other types of flanges, as the alignment of the bolt holes does not have to be exact.
