SLIPSIL - new generation sealing plugs
SLIPSIL, the new generation sealing plugs developed by BEELE Engineering, is designed to provide fire safe and gas and water tight seals for transits carrying single or multiple plastic or metal pipes.

Compared with other sealing plugs the SLIPSIL plug is even easier to install. The new design of the plug simplifies the installation and improves the tightness. The plugs can already be exposed to high pressures immediately after installation. Due to the new design much wider tolerances of ducted pipes and conduit sleeves can be adopted.

Optimized gas and water tightness is obtained by using the SLIPSIL sealing plugs in CSD embedded or flanged pipes. The sealing plugs also can be used in holes bored with diamond-tipped drills. The tolerances of the drilled hole should be within the tolerances of the plug series.

SLIPSIL offers the advantage of having one rubber type for most applications.

SLIPSIL is made of the superior rubber grade NOFIRNO and is developed by BEELE Engineering. NOFIRNO is a rubber compound that is not consumed by fire, does not shrink, and when exposed to flames forms a protective layer with a layer of char underneath. NOFIRNO rubber has excellent weathering properties, UV and ozone resistance and long term behaviour. Service life of the plugs easily exceeds 20 years under normal environmental conditions.

The plugs can be used in a very wide temperature range. Even at low temperatures down to -50° C the rubber stays flexible and does not harden excessively as other rubber types will do. This guarantees tightness even at low temperatures. The rubber can also be used in applications up to +180° C. A single rubber grade is now capable of satisfying almost all sealing conditions.

The SLIPSIL plugs can be exposed to fairly high pressure loads directly after installation. For optimum tightness on long term, the design and position of the profiles on the plugs is a determining factor. Also the quality of the used polymer and the hardness and compression set of the vulcanized rubber is most important.

Typical areas of application of the SLIPSIL plug are the construction industry, shipbuilding and the offshore sector, the oil refining and (petro)chemicals industry, and the utilities industry.

Why using SLIPSIL?

Using SLIPSIL offers advantages for the builder, the installer and the owner of the installation. The innovative design of the plug allows the shortest possible sleeve length for fire rated penetrations, and therefore reduces welding and cutting time. With SLIPSIL the necessary insulation is reduced to an absolute minimum, while the plug can be used for all types of metallic and plastic pipes. That simplifies material handling and reduces the costs of storage.

Installing the plug is extremely simple. The SLIPSIL plugs can be installed in minutes and do not require any bolting or other mechanical outfitting. SLIPSIL plugs cause no mechanical stress and avoid corrosion problems. That offers owners of ships or buildings the possibility to save on maintenance costs.
