DR 93159

Proposes requirements and dimensions for circular, plain, screwed, blank, boss, integrally cast or forged and welding neck type flanges or nominal sizes between 15 and 3000 and their bolting for use on pipes, valves and fittings and other pressure-retaining equipment containing fluid at pressures up to 19 300 kPa and at temperatures in the range -200 degrees Celsius to +525 degrees Celsius. Flanges in carbon steel, carbon-manganese steel, alloy steel, stainless steel, grey iron, malleable iron, ductile cast iron or copper alloy, together with relevant material specifications, are included. This proposed Standard is applicable to flanges for water, steam, compressed air, chemical and petroleum plants, hydraulic piping and where other standards require compliance with this proposed Standard. Recommendations on the selection of bolting and method of making flanged joints are included. This proposed Standard is not intended to apply to flanges for water or waste water covered by AS 4087.
