Plug-In Couplings For Pipelines (New System)

Plug-in couplings for pipelines

Different plug-in couplings are used for various applications (see Allocation).

Opening and joining plug-in couplings

Important notes
Plug-in couplings are components that permit simple, fast and precise connection of pipelines.

These precision components must be handled carefully during repairs.
Excess force during assembly work, damage to the sealing surface and soiling can cause leakage.

Perform preparations carefully when handling plug-in couplings - e.g. cleaning and fitting the plugs - as repairs are possible only by replacing the affected line in most cases.

After separating the plug and socket piece, carefully protect them against dirt and scratches with caps.

Join the plug-in connection only in a straight line. Never use excessive force.
Pull slightly to make sure the connection is locked properly.

Illustration of procedure

Note:
The plug-in coupling is opened by unscrewing.

Pipelines the were fitted once before are joined by screwing together (as opposed to new lines and steering lines, which are plugged together). This is necessary because holder C is located very deep in the threaded part of the plug-in coupling and cannot be removed with conventional workshop equipment.




Numbered procedures and instructions

* On new pipelines, the plug-in coupling - including holder C - has already been screwed together. All that remains is to insert (engage) the plug of the mating pipeline in a straight line.
