Within the fluid power industry, many criteria are used for the determination of pressure capability. Various fibre stresses, minimum yields and design factors are applied, commensurate with total system conditions. Thus, it is impractical to lay down specific allowable Working Pressures that satisfy all design criteria. Unless otherwise specified in this document, and given correct Working conditions, including, but not limited to, torque setting, assembly, alignment, support, Pressures (internal and external), temperature limits, environmental, installation, vibration free, damage free, chemical, cleanliness and regular maintenance and inspection, the following may be used as a Guide to maximum Working pressure.
