Pressure Equipment Directive 2014/68/EU (PED)

For process plants the PED is relevant for the sizing and procurement of vessels and pipes. Vessels and pipes with a design pressure of more than 0.5bar above the atmospheric pressure of 1.013bar(a) are divided into five categories based on a pattern defined by the PED. Depending on the category, the production process must be monitored by given conformity assessment procedures. The category assignment depends on several factors. Vessels and pipes are treated differently. The design pressure is taken into account, as well as, in the case of vessels, the volume, or, in the case of pipelines, the nominal diameter. The process media is classified as either dangerous or not dangerous and as either gaseous or liquid. Liquids with a vapour pressure at the maximum allowed temperature of more than 0.5bar above the atmospheric pressure of 1.013bar(a) are treated as gaseous.

What we can do for you!

We ensure that the conformity assessment procedures as required by the PED are applied for the production of all pipes and vessels of the plant.

We investiate options to reduce costs by adjusting the design of vessels and pipes with the aim of attaining a lower category according to the PED, so that the conformity assessment procedures for the production process become simpler or do not apply at all.
