Slip on Raised Face Flanges Stainless Steel Slip On Raised Face Flanges is a raised face because the gasket surfaces are raised above the bolting circle face. Slip On Raised Face Flanges are manufactured with an inside diameter slightly bigger than the pipe's outside diameter. Alloy Steel Slip On Raised Face Flanges can also be a plate or ring to form a rim at the end of a pipe when fastened to the pipe. Rf slip on flange also has differing pressure and temperature ratings for different materials. Duplex Steel Slip On Raised Face Flanges is a connection of pipes, where the connecting pieces have flanges by which the parts are bolted together.
A SORF flange is a flange welded outside a pipe & designed to slip over the pipe. These flanges are commonly used in various industries and are known for their durability and strength. They are also available in different types such as ring style, flat face, and spiral double jacketed. In addition, there are some benefits to using SORF flanges, including the ability to use a variety of gaskets.
