Status: Effective - Supersedes. IUS 2-2016

This standard applies to connecting flanges of pipe fittings (hereinafter referred to as valves), connecting parts and pipelines, as well as to connecting flanges of machines, equipment, instruments, pipes, apparatus and tanks for nominal pressure up to PN 250 and establishes the design and dimensions of steel and cast iron flanges, determines the types of flanges, the types of forms of sealing surfaces, sets the technical requirements for the manufacture, marking, testing and control. This standard provides guidance on the choice of material for flanges and fasteners for flange joints as well as on the choice of a sealing surface depending on the hazard and the parameters of the working medium. On the flanges for other objects, parameters and conditions of application are GOST 1536, GOST 4433, GOST 9399, GOST 25660, GOST 28759.1-GOST 28759.5, [1]

Настоящий стандарт распространяется на присоединительные фланцы трубопроводной арматуры (далее - арматуры), соединительных частей и трубопроводов, а также на присоединительные фланцымашин, оборудования, приборов, патрубков, аппаратов и резервуаров на номинальное давление до PN 250 и устанавливает конструкцию и размеры стальных и чугунных фланцев, определяет типы фланцев, типы форм уплотнительных поверхностей, устанавливает технические требования к изготовлению, маркировке, испытаниям и контролю. В настоящем стандарте приведены рекомендации по выбору материала для фланцев и крепежных деталей фланцевых соединений а также по выбору уплотнительной поверхности в зависимости от опасности и параметров рабочей среды. На фланцы для других объектов, параметров и условий применения действуют ГОСТ 1536, ГОСТ 4433, ГОСТ 9399, ГОСТ 25660, ГОСТ 28759.1-ГОСТ 28759.5, [1]
