Rated working pressure

The maximum internal pressure that the equipment is designed to contain and/or control. For an RCD, there is no designated rated working pressure since the maximum internal pressure that the equipment is designed to contain and/or control depends on the operation: dynamic—pipe rotating, stripping—pipe reciprocating or tripped but not rotating and static—no pipe movement.
