Roxtec has extended its range of plastic pipe seals to meet the demand for high quality light-weight aluminium solutions in the marine and offshore sector. From now on, the Roxtec Sleev-it™ penetration seals are available not only in steel, but also with an aluminium flange – for use in aluminium decks and bulkheads.
The increasing use of aluminium structures in shipbuilding is based on requirements for lower weight, reduced fuel consumption and higher speeds. Ships and vessels constructed of aluminium are also likely to ensure lower costs for lifecycle maintenance and ownership. The new seals from Roxtec are expected to be frequently used on cruise liners and high-speed ferries, as well as on LNG carriers.
The Roxtec Sleev-it™ penetration seals with aluminium flanges are approved for both A-60 and A-0 fire rated divisions and type approval certificates are now available. The waterproof version is also approved for 1 bar water-tightness and 0.67 bar gas-tightness.
The Roxtec Sleev-it™ Fire penetration seal contains intumescent material, which effectively closes off the plastic pipe penetration in case of fire. It is openable and can be used for both new-build and retrofit projects. The Roxtec Sleev-it™ Waterproof penetration seal has similar properties, but includes a rubber grommet for additional protection against gas and water. The seals are ideal for pipe penetrations above the waterline onboard various ships and vessels. They are light-weight and easy to install from one side of the deck or bulkhead.
