Plugs and sensors, plug-in pipe connections
Plugs and sensors (a)
Screwed-in seal plugs (4) are sealed toward the outside either with a copper sealing ring (1), according
to DIN, or an O-ring (ISO).
In case of a loose thread or a defective sealing ring (1), the liquid first has to pass the thread.
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)
The sleeve (3) covers the joint to prevent lateral spray.
Only leak-off along the line is possible, the pressure is decreases significantly if an O-ring (2) defect
occurs.
The connection is confirmed as compliant with SOLAS by DNV and GL.
