The increasing use of aluminum structures in shipbuilding is based on requirements for lower weight, reduced fuel consumption and higher speeds. Ships and vessels constructed of aluminum are also likely to ensure lower costs for lifecycle maintenance and ownership.

Transit specialist Roxtec has extended its range of plastic pipe seals to meet the demand for high quality light-weight aluminum solutions in the marine and offshore sector. The Roxtec Sleev-it penetration seals are now available not only in steel, but also with an aluminum flange – for use in aluminum decks and bulkheads. The manufacturer expects the new seals to be frequently used on cruise liners and high-speed ferries as well as on liquefied natural gas (LNG) carriers.

The seals for aluminum structures 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 efficiently closes off the plastic pipe penetration in case of fire. It is openable and can be used for both newbuild 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 suited for pipe penetrations above the waterline onboard various ships and vessels. They are lightweight and easy to install from one side of the deck or bulkhead.
