Bibliography

Defines requirements for a series of carbon steel, alloy steel, cast iron and copper alloy flanges, and also appropriate bolts and nuts, for use with pipes, valves and fittings containing steam, oil, compressed air or water.

This British Standard specifies requirements for a series of carbon steel, alloy steel, cast iron and copper alloy flanges, and also appropriate bolts and nuts, for use with pipes, valves and fittings containing steam, oil, compressed air or water.

NOTE 1 The use of flanges complying with this standard for temperatures below −17.8 °C (0 °F) should be agreed between purchaser and manufacturer. These flanges may also be used on pipes, valves and fittings carrying other fluids for which the same requirements for safety and joint tightness are appropriate.

The applicability relationship between temperature and pressure for the above materials is specified for each table of flanges in Table 2 and Annex B.

NOTE 2 The types of gasket, and gasket materials, and the surface finish of the jointing face are matters for agreement between the purchaser and the manufacturer. When a raised jointing face is specified the outside diameter of the gasket should extend at least to the outside diameter of the raised face. For steel flanges when a raised jointing face is not specified, the gasket should be within the bolt holes.
