Plugs and sensors, plug-in pipe unions
Seal plugs and sensors (a)
Screw seal plugs (4) are either sealed with copper sealing rings (1) as per DIN or O-rings (ISO).
In case of a loose union or a faulty 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 pres-
sure.
Plug-in pipe connection (b)
The sleeve (3) covers the union to prevent lateral spray.
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.
