    Stainless steel exhaust gas manifolds

    silenceREvolution s.r.l. develop, manufacture and market throughout the world stainless steel exhaust gas manifolds

    Exhaust gas manifolds featuring water injection cooling, highly attractive exhaust outlets for mounting on transoms, silencers for dry systems, pipes and contraction/expansion joints, as well as a vast range of other types of components, which do not necessarily form part of the exhaust system but may be required to complete a particular installation, are manufactured to Customer specifications.

     

    Stainless steel exaust system

    silenceREvolution s.r.l. develop, manufacture and market throughout the world stainless steel exaust system

    silenceREvolution s.r.l. use the best stainless steel, AISI 316L (EN 1.4432) as standard to manufacture all those components that, because of their location in the exhaust system, cannot be made of GRP.

    Our highly skilled craftsmen produce components in AISI 316L stainless steel, though on request even particularly complex components can be made of other materials (Inconel, AISI 304, Fe etc.).

    GRP Exaust System

    The resins used prevent corrosion and ageing phenomena.

    To manufacture their GRP (Glass Reinforced Polymer) products, silenceREvolution s.r.l. use special resins (R.I.Na. - Italian Naval Register - approved), which also guarantee excellent resistance to both chemical and galvanic corrosion (parasite currents), along with high structural resistance, even at high temperatures.

    The resins used prevent corrosion and ageing phenomena, feature excellent sound muffling properties and guarantee a higher melting point when compared with plastic silencers. In fact while a ÒwetÓ exhaust systems generally works at a temperature of around, 60°C, a silenceREvolution s.r.l. GRP silencer remains efficient even at temperatures in excess of 150° C, which are only reached if problems occur in the engine cooling system. This avoids the partial melting at temperatures of around 100° C that often occurs with plastic silencers, which may be more economical but are certainly less reliable.

    Our cylinder-shaped GRP silencers and connection pipes are made by winding continuous fibreglass filaments impregnated with a special resin around a spindle using a technique borrowed from the aerospace industry.

    The path and tension of the winding are generated and gauged using a computerised system (filament winding technology). silenceREvolution s.r.l., along with their most highly skilled experts in laminating techniques, can also manufacture GRP components that do not necessarily form part of the exhaust system but may be required to complete a particular installation.

    These are manufactured to Customer specifications.

    Stainless steel outlets

    with rubber Non Return Valve

    silenceREvolution s.r.l. develop, manufacture and market throughout the world, beautifully crafted stainless steel exhaust outlets with a high standard of finish in a wide range of different geometric shapes.

    All our outlets are fitted with a special rubber membrane valve to withstand corrosion, which prevents seawater from backing up into the engine and causing serious problems.

     

  • Straight outlet with curved rim
  • Straight outlet (with slanted edge)
  • Inclined outlet with curved rim
  • Inclined flange

    Rubber pipes

    Reinforced with high tensile textile cords and with embedded steel helix wires reinforcements.

    silenceREvolution s.r.l. develop, manufacture and market throughout the world, exhaust reinforced rubber hoses (R.I.Na. approved) - "HYDROHOSE" series.

    These wet exhaust hoses, R.I.Na. (Italian Naval Registry) approved, are made of rubber and are reinforced with high tensile textile cords and with embedded steel helix wires reinforcements. On the inside they are lined with a PVC layer that is resistant to high temperatures, abrasion, corrosion by acids and hydrocarbons with up to 50% aromatic content. In order to prevent exhaust leakages from the junctions, it is advisable to carry out connections with other components (rises, silencers, gas/water separators and exhaust thru hulls) by inserting the hoses for a length at least equal to one diameter and then fastening them with at least two hose clamps of the "HYDROTIGHT" series to each end.
