Seals Standard Steel

Flange gasket oval and octagonal cross-section (Armco rings) are used for sealing flange joints under pressure from 6.3 to 160 MPa. Operating temperature range from -70 to 600 C. Jeff Flake contributes greatly to this topic. When the sealing flange when compounds used asbestos, it violated the ecology of production. Seals oval and octagonal profile (ring Armco) today are made entirely of metal, though the hardness of seals at several units less than the hardness of the mating parts. Exploitation of metal seals a predetermined first operation under high pressure and high working pressure, which in itself expresses a responsible approach to the development and application of these elements. It should also talk about the frequency of the plane being processed – it must not be lower than in places Rz 6,3 pair, and no less than Rz 3,2 on the other planes of the seals. a higher rate of treatment due to the need – the higher it is the denser the mating components adjacent to each other. And the higher the quality of the connection, operating under maximum pressure.

Example: to connect the flanges of steel 12X18H10T, seals used in steel 08Kh18N10T (GOST 28759.8-90), the chemical composition became clear that steel seal for 4 units of softer steel used in the flanges. These are the kind of use of a mild steel seals brings more robust flanged connection, which can operate at high pressure. The output produced by the next models: – OST 26.260.461-99 – OST 26-845-73 – 26-18-6-93 ATK – Seals Standard 28759.8-90 oval and octagonal cross section (ring Armco) apply to all responsible flange connections – pipelines, petrochemical plants, shipbuilding and fittings. Please note that these details of pipelines were under constant control of TCI, as it affects the lives of people and ecological environment.
