Special connections
The following connection types are spray-proof in case of leakage even without covers and have been
confirmed as being SOLAS-compliant by GL and DNV.
Plugs and sensors, plug-in pipe connections
Plugs and sensors (a)
Screw plugs (4) are either sealed with copper sealing rings (1) as per DIN or O-rings (ISO).
The fluid must first pass the thread in case of a loose threaded union or faulty sealing ring (1).
The pressure is so greatly reduced by this and the faulty sealing ring (1) that any leakage is not under
pressure.
Plug-in pipe connection (b)
Design precludes lateral spray as the point of separation is shielded by the sleeve (3).
Only seepage along the pipeline is possible whereby the pressure is greatly reduced by a faulty O-
ring (2).
The union is confirmed as being SOLAS-compliant by DNV and GL.
