Maritime Applications
Our Maritime Applications division specialises in the manufacture of pipes, fittings and flanges for seawater-carrying systems in shipbuilding, Oil & Gas offshore and onshore projects as well as other industrial applications in maritime environments.
Durable Products in highly corrosive Environments
For decades we have been supplying a unique range of seawater-resistant seamless or longitudinally welded pipes and pipeline components, which we manufacture as standard parts or develop and produce to match our customers' individual specifications.
These are made from copper-nickel alloys - a seawater-resistant material that is far superior to stainless steel or GRP components where there is contact with seawater.
Such alloys have excellent processing properties for the construction of plants and on site or on board, for example.
Our OSNA®-10 and OSNA®-30 alloys conform to all major international standards. Because we maintain tight tolerance limits in the composition of the materials, the pipes and components also have excellent cold formability and weldability.
Shipbuilding
Our seawater-resistant large pipes, which have diameters of up to 40 inches and delivery lengths of up to 6 m, have been used successfully on seagoing vessels for decades.
Offshore & Onshore
Our piping systems and fittings in sea-water resistant copper-nickel alloys prove their worth day after day on offshore production facilities such as drilling rigs, production platforms and FPSOs (Floating Production Storage and Offloading Units).
Our products also protect equipment in coastal areas, for example in seawater desalination plants or industrial plants, from seawater corrosion.
