The BS EN 12953 series is European Standard that discusses the shell boilers and their various requirements.
BS EN 12953-4 is one of the parts of the series that specifies requirements for the workmanship and construction of shell boilers as defined in EN 12953-1.
Shell boilers are ones in which all of the heat transmission surfaces are contained within a steel shell. Shell boilers are sometimes known as 'fire tube' or ‘smoke tube' boilers because the combustion products flow through the boiler tubes, transferring heat to the surrounding boiler water.
Note: For other components such as water tube walls, see the EN 12952 series.
Note: For economizers and super heaters, see EN 12953-4 or EN 12952-5.
BS EN 12953-4 on shell boilers is useful for:
Shell boilers are sometimes known as 'fire tube' or smoke tube' boilers because the combustion products flow through the boiler tubes, transferring heat to the surrounding boiler water.
BS EN 12953-4 establishes the requirement for the workmanship and construction of shell boilers as per EN 12953-1, That defines the design, construction, equipment, operational, and water treatment requirements drawn up with a view to ensuring the safety of new stationary shell boilers.
If you are a manufacturer or designer of shell boilers adopting the requirements of the workmanship and construction in accordance with BS EN 12953-4 can enable you to build high-quality and durable shell boilers that meet the safety requirements.
The best industry guidance in BS EN 12953-4 can assists you in achieving the reliability of shell boilers components that provide excellent performance and accuracy in pressure components of the boiler.
Workmanship and development guidance in BS EN 12953-4 will help you in commissioning and installations of shell boilers according to best industry standards.
