Vessels, pipeline, safety accessories and pressure accessories, including elements attached to pressurized parts like flanges, fittings, sleeves, supports and movable wings are the pressure equipment:
- Vessel: a housing designed and built to contain fluids under pressure including its direct attachments up to the coupling point connecting it to other equipment; a vessel may be composed of more than one chamber.
- Piping: piping components intended for the transport of fluids, when connected together for integration into a pressure system; piping includes in particular a pipe or system of pipes, tubing, fittings, expansion joints, hoses, or other pressure-bearing components as appropriate; heat exchangers consisting of pipes for the purpose of cooling or heating air shall be considered as piping.
- Safety accessories: devices designed to protect pressure equipment against the allowable limits being exceeded.
When a manufacturer combines one or more pieces of equipment in order to build an integrated and functional assembly, a “pressure assembly” creates.
This equipment is regulated by the following European Directives:
Directive 2014/68/EU “Pressure equipment – PED”
Directive 2010/35/EU “Transportable pressure equipment – T-PED”
Directive 2014/29/EU “Simple pressure vessels”
Certification services in the field of pressure equipment are provided by CEC – Consorzio Europeo Certificazioni (Notified Body No. 1131), of which ANCCP Certification Agency is a founding member as well as the operational division.
