PED certification is a certification system under the European Pressure Equipment Directive (PED), used to ensure the safety of pressure equipment in the markets of EU member states. This certification system requires that equipment and components that can withstand pressures above 0.5 bar must comply with its regulations to ensure that these devices meet safety standards in their design and manufacturing processes
Definition and Scope of PED Certification
PED certification applies to pressure equipment and components with a maximum allowable pressure greater than 0.5 bar, including containers, pipelines, safety accessories, and pressure accessories. The specific types of equipment covered are as follows:
Pressure vessels: Design and manufacture shells for loading pressure fluids, such as storage tanks, heat exchangers, towers, etc.
Pipeline: Pipeline components used for transporting fluids, such as steam pipelines, chemical process pipelines, etc.
Pressure accessories: shells with operational functions and pressure bearing, such as valves, filters, flow meters, etc.
Safety accessories: devices designed to prevent pressure equipment from exceeding allowable limits, such as safety valves, bursting disc devices, and pressure devices
