Steel flanges according to DIN EN 1092-1 are manufactured according to European standards established by the German Institute for Standardization (DIN - Deutsches Institut für Normung) and the European Committee for Standardization (EN - European Committee for Standardization).
The DIN EN 1092-1 standard specifies the requirements for flanges and their connections for pipes, valves, fittings, etc., designed for a pressure of PN 2.5–40.0 MPa and a nominal diameter of DN 10–4000 mm. The standard specifies types, sizes, materials, tolerances, threads, surface treatments, flange markings, weights, bolt sizes and pressure versus temperature.
Structurally, steel flanges according to DIN EN 1092-1 are similar to flanges according to domestic standards and have the same types of sealing surfaces, however, there are some differences in the geometric dimensions of the products. The ranges of permissible pressures for different diameters also differ. The dimensions of the sealing surfaces, as well as the height of the protrusion, the diameter, and the depth of the cavity, are not identical to domestic standards. Therefore, the EN 1092-1 flange does not have an analogue of GOST.
The ring billet plant produces steel flanges DIN EN 1092-1 type 01 flat welded flange and 11 welded flange, nominal diameter from DN 400 to DN 1400 and pressure from PN 2.5 to PN 25.0 MPa from various steel grades. It is also possible to design and manufacture transitional and non-standard flanges according to your drawings and in accordance with technical requirements.
Flanges are tested for tensile strength, yield strength and impact strength, and mechanical properties are determined. The products comply with the requirements of the technical regulations of the Customs Union of the EAEU TR CU 032/2013, supplied with quality certificates.
The warranty period for flanges is 24 months.
It is possible to buy or find out the price for steel flanges according to DIN EN 1092-1 at the Ring Billet Plant.
