Steel tube solutions for shipbuilding

High strength steel for static requirements, tubes for conveying liquid and gaseous media or fittings and flanges to connect tubes. Shipbuilders source these products in a high quality from BENTELER.

Especially the BENTELER PreFiS press fitting system is very much appreciated: bonding tubes quickly, without welding and even in narrow spaces. The system consists of robust metal seal fittings. Special ergonomic tools press the fittings within seconds onto the tubes. In combination with our tube expertise you get a reliable and long-lasting tube bond.
