The DYNATITE system has been specifically designed for application in columns of offshore oil rigs, where penetrations may be subjected to sudden extreme pressure loads. The system is also suitable for use in a wide range of other environments where penetrations may be suddenly exposed to extreme conditions. These include for example partitions between hazardous and non-hazardous areas, blast walls, explosion-proof areas, and regions with elevated hurricane and tsunami risks.

The DYNATITE system consists of plugs which are made of a special polymer rubber compound. The plugs are provided with a special profile designed to enable the desired deformation to be achieved under pressure loading. As a result of this profile together with the compound used ensures that the plug will return to its original shape even after being subjected to severe shock pressure loads.

The DYNATITE plug fits exactly inside DYNATITE conduits, and once installed the plug flange lies flush with the front side of the conduit sleeve or module. A specially designed retainer ring is positioned in the conduit opening in order to secure the compressed rubber mass tightly under pressure loading. The use of modified retainer parts enables pressure loads at both sides of the conduit sleeve or module to be absorbed and also allows extreme displacements of the structure to take place. To assure fire safe performance, conduit openings should be sealed at each end by means of a DYNATITE plug.

In spite of the fact that this new system by Beele Engineering is extremely simple to install, the DYNATITE plug is capable of withstanding pressure loads in excess of 10 bar.
