Pressure Equipment   -   PED (97/23/EC) CE marking

Since 30/05/2002 the PED is obligatory throughout the EU.
The directive supplies, together with the directives incidental to simple pressure vessels 2009/105/EC, transferable pressure equipment 99/36/EC & Aerosol Providers 75/324/EEC a comprehensive structure for safety.

The Directive business concern items such as crafts, pressurized store containers, heat exchangers, steam setups, boilers, industrial piping, safety devices and pressure supportive. Such pressure equipment is widely used in the activity industries oil and gas, chemical, pharmaceutic, plastics & rubber & the food & drink industry, full temperature process industriousness glass, paper & commission, energy manufacture & in the supply of utility, heating plant, air conditioning & gas store & transportation system.

Pressure Equipment Directive compliance complete & above other demands, usually needs making design calculations as per EN Standard and success Special process such as welding as per EN Standards & assuring that the material used is like to that specified in the relevant EN standards


Pressure Equipment Directive 97/23/EC (PED)

 In order to ensure a consistent practical application of the PED (Pressure Equipment Directive 97/23/EC), Guidelines are developed in agreement by the Administrative body WGP (Working Group Pressure ). This working group, made as a result of Section 17 of the Pressure Equipment Directive, which requests the Member Authorities to get together in order to assist the functioning of this Directive. It is combined of agents of Members States, European organizations, the Notified Bodies Assembly and CEN.
