Piping Systems: British Codes and Standards

Further to my last post about the Codes and Standards used in designing piping systems, British standards are used in many countries like India.

There are many British Standards available which can be used instead of American Standards in piping engineering. The general referred British codes and standards for piping systems are:



BS 10 – Specification for Flanges and Bolting for Pipes, Valves and Fittings.

BS 806 – Specification for design and construction of ferrous piping systems installations for and in connection with land boilers

BS 970 – Steel for forging, bars, rods, valves steel, etc.

BS 1212 – Specification for float operated Valves

BS 1306 – Specification for copper and copper alloy pressure piping systems

BS 1414 – Specification for steel wedge gate valves (flanged and butt-welding ends) for the petroleum, petrochemical and allied industries

BS 1560 – Steel Pipe Flanges

BS 1600 – Specification for dimensions of steel pipe for the petroleum industry

BS 1640 – Specification for steel butt-welding pipe fittings for the petroleum industry.

BS 1868 – Steel Check Valves for Petroleum Industry




BS 1873 – Steel Globe and Check Valves for Petroleum Industry

BS 1965 – Butt Welding pipe fittings

BS 2598 – Glass Pipelines and Fittings

BS 3059 – Boiler and Super Heater tubes

BS 3293 – C.S Flanges (26”-48” NB)

BS 3381 – Metallic Spiral Wound Gaskets

BS 3600 – Dimensions of Welded and Seamless Pipes & Tubes

BS 3601 – C.S Pipes & Tubes for pressure purposes at room temperature

BS 3602 – C.S Pipes & Tubes for pressure purposes at high temperature

BS 3603 – C.S. and Alloy steel Pipes & Tubes for pressure purposes at low temperature

BS 3604 – Alloy steel Pipes & Tubes for high temperature

BS 3605 – S.S. Pipes & Tubes for pressure purposes

BS 3799 – SW/Screwed Fittings

BS 3974 – Pipe Hangers, Slides & Roller type Supports

BS 4346 – PCV pressure pipe-joints & Fittings

BS 4504 – Steel, CI & Copper alloy Flanges

BS 5150 – CI Wedge and Double Disc Gate Valves for general purposes

BS 5151 – CI Gate (parallel slide) valves for general purposes

BS 5152 – CI Globe & Check valves for general purposes

BS 5153 – CI Check valves for general purposes

BS 5154 – Copper alloy Gate, Globe, Check valves

BS 5156 – Diaphragm valves for general purposes

BS 5158 – CI and CS Plug valves for general purposes

BS 5159 – CI and CS Ball valves for general purposes

BS 5160 – Flanged steel Globe and Check valves for general purposes

BS 5351 – Double flanged Cast Iron wedge gate valves for water works purposes




BS 5352 – Steel Ball Valves for Petroleum Industries

BS 5353 – Steel Gate, Globe, Check Valves <2” NB

BS 5391 – Specification for Plug Valves

BS 5392 – Specification for ABS Fittings

BS 5433 – Specification for underground Stop Valves for water services

BS 5480 – Specification for GRP Pipes and Fittings

BS 6364 – Specification for Valves for Cryogenic Services

BS 6755 – Testing of Valves

Other than American there are British, German, Japanese standards etc available. One of me major organizations for standards are above British standards in piping systems.
