6.4. Assembly and disassembly of flanged equipment
Ensure that the joint is fully extended and the stop of both, the socket and the spigot end are in contact with the locking
strip. Assembling flanged parts (equipment, valves, adjusting pieces, orifice flanges etc.) one must bear in mind that
these parts could also be dismantled. To provide space for disassembly in any installation there must be a rubber seal
joint at one side. This allows some displacement in the axial direction using the clearance in the socket.
