scope:

This British Standard specifies requirements for the design and construction, including materials and design parameters, workmanship, inspection and testing, for ferrous pipes and piping installations for and in connection with land boilers.

This standard applies to the following.

(a) The ferrous pipework connecting steam generating plant to engine, turbine or industrial plant and all ancillary steam and water pipework in connection therewith.

(b) The pipes and pipe fittings forming parts of the installations described in (a) for:

(1) pipes of any bore, where the pressure exceeds 3.5 bar; and

(2) pipes over 250 mm bore for steam at pressures up to and including 3.5 bar.

NOTE 1. The term 'pipe fitting' used in this standard includes tees, elbows and special components, but excludes valves and everything covered by BS 759 and BS 6759.

(c) Ferrous pipes and piping installations constructed in materials used up to the design temperature limits.

This standard does not apply to the component parts of the boiler unit or to integral piping which are dealt with in BS 1113.

NOTE 2. Attention is drawn to the safety requirements specified in section seven of BS 1113 : 1992 for certain valves and fittings which may require installation in piping systems beyond the scope of BS 1113.

NOTE 3. The titles of the publications referred to in this standard are listed on the last page.
