Equipment operating under pressure, referred to as Pressure Equipment, is categorised according three main parameters:
- The nature of the fluid contained.
- The volume of fluid.
- The maximum permissible pressure.
Depending on the codes applied in the country of use typical and the application for the equipment differing codes may be applied to the construction and certification of this equipment.
- In Europe: The Pressure Equipment Directive (PED) prevails. It imposes the use of a harmonised of local calculation code for the pressure containing parts such as:
- RCC-M for nuclear ESPs
- In North America: the ASME code prevails.
- Other standards exist in other parts of the world: for example, the GOST and Rostechnadzor certification system for Russia
- In the field of the MARINE: international codes apply, and certifications are obtained by classification societies (Lloyd's, DNV, Bureau Veritas, etc)
Babcock Wanson has all the approvals and skills required for the manufacture and certification of pressure vessels and is thus able to meet most local requirements.
