Ещё 1376 / 5000 Результаты переводаOval and octagonal steel gaskets for flanges of fittings GOST R 53561-2009 are used to ensure high sealing of flange joints under high pressure and temperature conditions.
Oval and octagonal gaskets are designed to seal flange connections with flanges of nominal diameter DN from 10 to 400 mm, for nominal pressure PN from 6.3 MPa to 20.0 MPa. The gasket is installed in the groove of the flange and when the fasteners are tightened, the end mating surfaces of the oval-shaped gaskets and the wall of the groove of the flange come into contact. As a result of such a seal, the reliability and tightness of the flange connection is ensured. In this case, tight contact of the gasket with each flange occurs in two areas at once: along the inner and outer contour of the gasket.
Oval and octagonal steel gaskets are tested for mechanical properties. 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 oval and octagonal steel gaskets is 24 months.

Ещё 1834 / 5000 Результаты переводаThis standard establishes the design, dimensions and general technical requirements for oval and octagonal steel gaskets for flange connections of valves and pipelines for nominal pressure PN from 6.3 to 16.0 MPa and temperature from minus 70 to 600 ° C. The Ring Billet Plant manufactures steel gaskets from DN 150 to DN 400 mm.
Gaskets with an oval section OST 26.260.461 99 are installed for the tightness of the connecting surfaces that arise in the connecting parts of equipment, pumps, fittings with high pressure, pumps, and compressor equipment. Such equipment is most often used in petrochemical engineering, gas and oil production, oil refineries and other industrial sectors.
Metal oval gaskets are installed in special grooves of the flanges and have an oval shape. During the installation process, such a connection becomes as tight and tight as possible. The installed seal is blow-resistant and has a double sealing area. The contact between the rounded surface and the groove wall is subject to concentrated stress, which guarantees a good seal even when the flange is worn.
Oval and octagonal steel gaskets are tested for mechanical properties. 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 oval and octagonal steel gaskets is 24 months.

Больше информации об этом исходном тексте Чтобы получить дополнительную информацию, введите исходный текст Отправить отзыв Боковые панелиSteel oval and octagonal gaskets are used as a sealing product for flange connections of fittings with flanges having a sealing surface of version 7 according to GOST 12815 and version J according to GOST 33259-2015, for nominal pressure PN from 6.3 to 16.0 MPa and temperature from minus 70 to 600 ° С. Armco rings maintain the tightness of the network when working with high and overpressure and its sharp drops. Flange seals are used in cases where parts of other types are not suitable for their strength or technical characteristics.
The ring billet plant produces steel gaskets in accordance with OST 26.260.461-99, from low-alloy, carbon and corrosion-resistant steel grades, such as 08KP, 10895, 20, 09G2S and 08X18H10T in accordance with GOST R 53561-2009, GOST 28759.8-90.
Types of flange gaskets:
- oval - gaskets that have a double sealing area, and due to the rounded surface, stress concentration arises at the contact between the gasket and the groove wall, which ensures tightness even on worn flanges;
- octagonal - spacers that are placed in special trapezoidal grooves. These products have a double sealing area, which guarantees tightness even in harsh working conditions
For the most tight fit of the metal gaskets to the grooves of the sealing surfaces of the flanges, it is necessary to tighten the studs or bolts that are responsible for fixing the flange connection as tightly as possible. As a result, a very high pressure will be exerted on the insignificant contact surface of the metal gasket with the grooves of the sealing surfaces of the flange products, which will provide the most effective sealing.
The material of the flange joint gasket should be comparatively softer than the flange material, even when using a metal gasket. Steel gaskets are made of carbon and stainless steel. When the flanges are compressed by fasteners (pins, nuts, bolts), a high pressure is exerted on the relatively small contact surface of the metal gasket with the grooves of the sealing surface of the flange product. As a result, the deformation of the gasket element, made of a material softer than the base material of the flanges, occurs, due to which the sealing is especially effective.
The manufacture of metal gaskets is a complex high-tech process, which makes their cost quite high. However, it is impossible to do without them when operating pipeline systems with high temperatures or chemical aggressiveness of the transported substance.
