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 parting line 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 so greatly reduced by this and the faulty sealing ring (2) that any leakage is not under
pressure.

The HP fuel line is sealed by the thrust ring (8).

If leakage in the area of the thrust ring (8) or the HP line (5) occurs, the emerging fuel is routed to the
leakage chamber.

Leak fuel is allowed to escape without pressure via the leakage overflow bore (7). The leakage chamber
is sealed toward the outside by the O-rings (3).

This prevents leaking fuel from escaping.

The union is confirmed as being SOLAS-compliant by DNV and GL.

Shielding with plastic ring

The plastic ring (1) precludes lateral spray.

The fluid is diverted to the catch basin whereby the pressure is greatly reduced.

Shielding by structural overhang

The overhang (1) prevents lateral spray.

The fluid is diverted to the catch basin whereby the pressure is greatly reduced.
