Description

Flange decorative nerzh. AISI - 430

The flange with an opening is intended for a ceiling cap of openings between a pipe and a wall.

Flange (from it is mute. Flansch) — a flat detail of a square or round shape with evenly located openings for bolts and hairpins , serving for strong and tight connection of pipes, pipeline fittings , accession them to each other, to machines, devices and capacities, for connection of shaft and other rotating details (flange connection). Flanges use in pairs (set). Execution of flanges regulates GOST 12815-80 , and it depends on the working pressure on which the flange or flange connection pays off.

Flanges differ on types: flat, vorotnikovy flanges, on a free ring, flanges of vessels and devices.

The Russian standards regulate pressure of the environment of pipelines and connecting parts, and also on connecting flanges of fittings, connecting parts of cars, branch pipes of devices and tanks on the conditional pressure of Ru from 0,1 to 20.0 MPas (from 1 to 200 kgfs/cm ²)

Flanges are made according to normative documents:

  • flat flanges — GOST 12820-80;
  • vorotnikovy flanges — GOST 12821-80,
  • free flanges on a welded ring — GOST 12822-80.

Also flanges can be made on

  • DIN (Deutsches Institut für Normung e.V., German institute of standardization);
  • to the American ANSI/ASME B 16.5, ANSI/ASME B 16.47 standards .

Flanges of vessels and devices are made on

  • GOST 28759.1-90 "Types and parameters",
  • GOST 28759.2-90 "Flanges of vessels and devices flat - a design and the sizes",
  • GOST 28759.3-90 "Steel welded end-to-end",
  • GOST 28759.4-90 "Flanges of vessels and devices under laying of octagonal section".

From 01.04.2012 state standard specification P 54432-2011 "Flanges of fittings, connecting parts and pipelines on nominal pressure from PN 1 to PN 200" is enacted. A design, the sizes and the general requirements" instead of the collection state standard specification 12815-80 - state standard specification 12822-80 "Flanges of fittings, connecting parts of pipelines"

The most widespread ways of production of flanges: forging on a podkladny ring (stamping) , centrifugal electroslag molding (TsEShL), production from raskatny rings (forging), plasma (laser or gas) is sharp from a leaf.

Recently in connection with transition of many Russian enterprises to the equipment made according to the American and German standards (ANSI/ASME, DIN/EN) the need for non-standard "transitional" flanges appeared. On "transitional" flanges the connecting surface is made according to the import standard, and "vorotnikovy" (yubochny) part of a flange in accordance with GOST (under the Russian size of pipelines).
