适用范围：1 This British Standard specifies requirements for the design and the manufacture, including materials and design stresses, workmanship, inspection, testing, documentation and marking, valves, gauges and fittings of: a) water-tube steam generating plant subject to internal pressure; and b) parts of steam and water heating plant used in association with steam generating plant. 2 In addition to the definitive requirements, this standard also requires the items detailed in 1.5 to be documented. For compliance with this standard, both the definitive requirements and the documented items have to be satisfied. 3 This British Standard applies to the following types of plant. a) Water-tube boilers including their integral steel tube economizers and superheaters and all other parts connected to the boiler without the interposition of a shut-off valve with the exception of valves and fittings specified in section 7. Water-tube boilers are divided, for the purposes of this British Standard, into the following three classes. 1) Natural circulation boilers, in which the circulation of the water through the tubes is a result of the thermo-syphonic head produced by heating. 2) Forced, assisted or controlled circulation boilers, in which a pump is used either entirely or partly to promote circulation of the water through the tubes. 3) Once-through boilers, in which the feed pump is used to force the flow of water and steam through the tubes. b) Steam reheaters (either integral with the boiler unit or independently fired) receiving steam which has passed through part of a turbine or other prime mover. c) Independently fired steam superheaters. d) Integral superheaters separated by a shut-off valve from the evaporative circuits. e) Steel tube economizers (either integral with the boiler or independently fired) separated by a shut-off valve from the boiler. NOTE. For convenience, the term 'boiler' used throughout this standard includes the types of plant described in a) to e). 4 This standard applies to the pressure parts of boilers and superheaters (as described in 1.1.3a) and d)) containing water and steam up to and including the valves separating these water and steam spaces from the steam pipes to other equipment, water supply pipes, drain pipes and the surrounding atmosphere (safety valves and vents). In the case of reheaters (see 1.1.3b), this standard applies to pressure parts from the piping connection(s) at the inlet header to the piping connection(s) at the outlet header except that where a device is provided in reheat piping to blank off the reheater for hydraulic testing, this standard applies up to and including this device. In the case of independently fired superheaters (see 1.1.3c), and economizers (see 1.1.3e), the standard applies to the pressure parts containing steam and water respectively between the inlet and exit valves, including the respective valves and connections to drain pipes and to the atmosphere. 5 Section 4 of this standard (manufacture and workmanship) includes requirements applicable to the normal function of the boilermaker. Requirements for the quality of workmanship of plates, tubes, forgings and castings in the condition in which they are normally supplied to the boilermaker are included in the standards in the series specifying such materials. 6 This standard does not apply to brickwork or other settings or supports, or to insulation, or to air preheaters, mechanical stokers, fuel burning or ash disposal equipment, forced or induced draught equipment or their accessories. These items are matters for mutual agreement between the purchaser and the manufacturer. NOTE. Where such items are required or contemplated, it is recommended that all particulars which could affect the boiler(s) should be disclosed by the purchaser to the manufacturer at the time of the enquiry. 7 This standard applies only to boilers manufactured under the survey of a competent engineering Inspecting Authority or organiza
