At Turnbull & Scott, we are committed to maintaining the highest standards of quality and safety in all our engineering and manufacturing processes. Typically, we operate under the British Standard BS EN 13445 and the Pressure Equipment and Safety Regulations (PESR) for UK supply and Pressurised Equipment Directive (PED) for EU/EEA territories, UKCA / CE marking products where appropriate. Atypically, however, we also consider a wide range of worldwide standards.
BS EN 13445: Unfired Pressure Vessels
This European Standard provides a comprehensive guideline that ensures the integrity and safety of unfired pressure vessels. BS EN 13445 is specific to the design, fabrication, and inspection requirements necessary to manage the risks associated with high-pressure products. By following this standard, we ensure our products are robust, reliable, and fit for purpose, meeting all necessary European regulations.
BS EN 12952: Water-tube boilers and auxiliary installations
This standard encompasses design of boilers in general, but also fired process heaters such as economisers and is used where the exchangers may be exposed to close coupled heat sources.
PD 5500: Specification for unfired pressure vessels
PD 5500 is a Published Document (PD) that specifies essential safety requirements for the design and fabrication of pressure equipment and assemblies in the UK. It specifies requirements for the design, manufacture, inspection and testing of unfired pressure vessels made from a variety of steels. It also includes information for the requirements of vessels made from aluminium, copper, nickel, and titanium. PD5500 is also regarded well worldwide, particularly in Commonwealth territories, and a number of other countries.
Turnbull & Scott also has experience designing exchangers with ASME and the French nuclear sector RCC-M codes and are happy to look at enquires outside of the above.
By adhering to these standards, Turnbull & Scott not only aligns with rigorous European safety regulations but also commits to delivering high-quality, safe, and reliable products to our customers globally.
