  • AS 1228-1997 Pressure equipment - Boilers

    This Standard sets out requirements for materials, design, construction, inspection and testing of boilers as defined in AS/NZS 1200. Specifically applies to design and construction of boilers including superheaters, reheaters and economizers. Incorporates the existing AS 1228-1990, Boilers-Water-tube, and AS 1797-1986, Boilers-Fire-tube, shell Learn More

    tubes surrounded by water in a shell. The furnace/flame volume can either be inside or external to the shell that contains the water. The upper steam capacity of fire tube boilers is about 20,000 Ibm/hr, and the peak pressure obtainable is limited by their large shells to about 300 psi. Fire-tube boilers are used for heating systems.Learn More

  • The Feedtank and Feedwater Conditioning | Spirax Sarco

    British Standards BS 2486 recommends pH 10.5 - 12.0 for shell boilers @ 10 bar, pH 9 could be used in higher pressure boilers only. To condition any suspended matter. This will be a flocculant or coagulant, which will cause the suspended matter to agglomerate and sink to the bottom of the boiler from where it can be blown down.Learn More


    The mechanical design of a shell and tube heat exchanger provides information on items such as shell thickness, flange thickness, etc. These are calculated using a pressure vessel design code such as the Boiler and Pressure Vessel code from ASME (American Society of Mechanical Engineers) and the British Master Pressure Vessel Standard, BS 5500.Learn More
