Gas-loaded accumulators for fluid power applications

Scope

1.1 This document specifies the requirements for materials, design, manufacture, testing inspection, safety equipment configuration and documentation (including instructions for first operation), for commonly-used types of gas-loaded accumulators and pressure vessels used to provide additional gas capacity for fluid power applications (see 1.2).
1.2 This document applies to the following types of components, defined as the pressure-containing envelope of gas-loaded accumulators:
- bladder type;
- diaphragm type;
- piston type;
- transfer type;
- pressure vessels used to provide additional gas capacity.
They consist of one or several parts joined together by a variety of mechanical means and by welding.
1.3 This document applies to gas-loaded accumulators which operate with the following conditions:
- subject to an internal gauge pressure greater than 0,5 bar;
- working temperature not lower than –50 °C and not higher than +200 °C;
- containing all liquids and gases as defined in the European Legislation on Pressure Equipment,
see Note.
NOTE When the accumulator contains Group 1 liquids or gases, consideration relating to risks other than those required by the European Legislation on Pressure Equipment are not covered by this document and will be assessed separately.
