Fit transit pipes without welding

Ever since the company’s foundation, approximately 45 years ago, Beele Engineering has constantly devoted attention to the installation simplicity of the company’s fire-resistant and gas, smoke and watertight systems. Now the company has once again developed a solution that it claims saves the installer a great deal of time and money: an assembly set that makes it possible to easily install flange transit pipes in steel decks, floors, bulkheads and walls without the need for welding. The set is specifically designed for SLIPSIL and SLIPSIL XL-120 plugs with which the ultimate transit sleeve can quickly and effectively be installed with a fire-resistant and gas, smoke and watertight seal.

Welding onboard ships is not only time-consuming, it is also physically strenuous due to the heavy tools and gas bottles used. This applies all the more when welding is needed in difficult to reach areas or areas that require a lot of climbing. Furthermore, welding entails a high fire risk and requires a waiting time to allow the welded installation to cool off. This way a great deal of expensive installation time is lost.

Netherlands-based Beele Engineering is now introducing a smart solution for this that makes it possible to simply screw pipe flanges in steel decks or bulkheads. The set consists of pipe flanges, a horseshoe-shaped guide ring, NOFIRNO gaskets and BEBOLTITE fastening bolts. To ensure optimal seal tightness, a NOFIRNO gasket is also integrated into the head of each bolt. The set is assembled by first turning one of the fastening bolts through the pipe flange and the NOFIRNO gasket into the guide ring. Next the ring is inserted through the opening in the bulkhead. After this the remaining BEBOLTITE fastening bolts are installed and tightened. Thanks to the quality of the NOFIRNO gasket, a tightening force of approx. 8Nm is sufficient to ensure a long-term watertight seal.

The transit sleeve can then be sealed using the SLIPSIL XL-120 plug. In addition, the transit sleeve is compatible with the SLIPSIL XL-120 blind plug to facilitate future pipework. Next, the plug sections are slid into the open space around the pipe, effectively sealing the transit.
