Jakob Hülsen GmbH & Co. KG manufactures reducers made of aluminum, copper and copper-nickel in various designs in accordance with ASTM B361, DIN 2616-1, DIN 2616-2 and DIN 86089. Due to their different properties, the reducers are used, for example, in shipbuilding, apparatus engineering, tanker construction, heating and sanitary systems and plant engineering in general.
Get to know our different products in the field of reductions:
The seamless concentric reducers made of aluminum acc. to ASTM B361 were cold formed and then heat treated acc. to AD-Merkblatt HP-7/4 and tolerances acc. to ANSI B16.9. Weld preparation was carried out sim. to ANSI B16.9. The seamless concentric reducers are suitable for processing in shipbuilding, plant and equipment construction, especially in the field of process engineering. The advantages are the low weight, very good seawater resistance and the temperature range from -270°C to +80°C.
The seamless eccentric reducers made of aluminum acc. to ASTM B361 were cold-formed and then heat-treated acc. to AD-Merkblatt HP-7/4 and tolerances acc. to ANSI B16.9. Weld preparation was carried out sim. to ANSI B16.9. The seamless concentric reducers are suitable for processing in shipbuilding, plant and equipment construction, especially in the field of process engineering.
The advantages are the low dead weight, a very good seawater resistance and the temperature application range from -270°C to +80°C.
At JHK you will find seamless concentric reducers made of aluminum cold formed acc. to DIN 2616-2. The front edges are sawn and deburred. The reducers can be used for processing in plant and apparatus engineering and in particular in the field of process engineering and in the field of tank vehicle construction. The low weight and the temperature range from -270°C up to +300°C depending on the product are the advantages of the reducers.

Due to the low weight and the high temperature resistance from -270°C up to +300°C depending on the design, the longitudinally welded, eccentric reducers made of aluminum can be used in ship, plant and equipment construction, especially in the field of process engineering. The reducers are manufactured acc. to DIN 2616-1 and cold formed.
Due to the high corrosion resistance and the temperature application range from -270°C up to +250°C, the seamless, concentric reducers made of copper with cylindrical ends are suitable for processing as welded parts in sanitary and heating systems in buildings, ships and related applications. The reducers are manufactured acc. to DIN 2616-2, cold formed and the front edges are unmachined.
Due to the high corrosion resistance and the temperature range from -270°C up to +300°C, the seamless, concentric reducers made of copper-nickel are suitable for use in shipbuilding and offshore applications for pipes passing through seawater and related applications. The reducers are manufactured acc. to DIN 86089 and cold formed.
