Free flanges made of stainless steel aisi 304 and aisi 316
The stainless steel free flange is intended for tight, durable connection of pipes, fittings, various parts of equipment or pipeline. The flange connection consists of two flanges, a gasket or O-ring, connecting pins and nuts. Free-type products can be used in process pipelines, in utilities. Among the advantages that the connection has with the help of flanges is the convenience of installation work, assembly and disassembly. The free steel flange is most often used where frequent disassembly and assembly of the pipeline is provided. It can be installed without using welding, which is important for workshops with explosive conditions.
The production of a free flange, the choice of material for its manufacture is regulated by the relevant GOST standards.
What technical and design features does the free flange have?
Stainless steel free flanges come with a collar, on a welded ring and on a flanged pipe. A variety of models allows you to choose the most convenient and reliable option for installation.
With a collar, flanges are used only to a limited extent, most often for the installation of pipelines with aggressive media, the material for the manufacture of pipes is alloy steel.
Flanges with a welded ring are used in pipelines made of stainless steel, copper or aluminum, brass. The flange ring is made of the same material as the pipe.
Free flanges with a flanged pipe are designed to connect parts of a non-ferrous metal pipeline. Free flanges, when used, provide a significant simplification of the assembly of flange connections during the installation of the pipeline system. To match the holes for the connecting bolts exactly, you just need to turn the ring around the pipe. For the density of the connection, a gasket is used, the material for which is selected taking into account the pressure, temperature in the pipes, and the nature of the working environment. Free-type flanges can have different sizes, this is due to the fact that they are needed to connect pipes with different diameters.
