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