Flat steel flange GOST 12820 80 is a significant part of pipelines, which belongs to the category of pipeline fittings. Flanges are necessary for the installation of pipeline systems and can be used as an independent fastener or as a part of flange connections.


Steel flanges are made of steel alloys, in strict accordance with the requirements for the features of operation and transportation of the working medium.


A steel flange is a disk or a flat ring equipped with special holes for fasteners that ensure a reliable and tight connection of products.


Any pipeline consists of pipes, valves, connecting elements and a control system. A flat flange (GOST 12820-80) is the most important part of the system, ensuring the simplicity and reliability of fastening pipeline parts to each other.


These parts are used to connect pipes to each other in series, as well as to connect and “tie in” any additional equipment (pumps, filters, valves). 


Our flanges are high quality products that can be used in all climates, high pressures and temperatures. Parts supplied by our company show themselves excellently in operation in the most severe conditions, regardless of the type of transported substance (water, hot steam, oil, chemical components, oil, gas).
