Hydraulics - on the road to success with a large variety of products
Our seamless and welded steel tubes withstand high pressure loads, resist high mechanical strain and stand out through their precise geometry. This is achieved by targeted selection and treatment of the material deployed. In addition, we use state-of-the-art technologies for tempering the tube product. We supply tube solutions in all common grades, standards and dimensions. Moreover, we offer a convincing portfolio with numerous processing capabilities and alternative grades.
For the production of cylinder applications, we manufacture tube solutions which are distinguished by excellent low-temperature toughness and consistent quality. What is more, our steel tubes prove through outstanding inner surface properties: They demonstrate exceptionally low inner roughness and boast particularly narrow inner diameter tolerances. Customer-specific machining allowances on the inner diameter are also part of our service. As a customer, you also benefit from our long-standing process expertise in the production of skived and roller-burnished tubes. These can also be supplied as tempered version.
Our piston tubes, which are developed with a great deal of know-how, are ideally suited for the most demanding applications: They are characterized by very narrow dimensional tolerances and low ovality. Moreover, they offer high straightness and low roughness which is achieved through process-regulating interventions during production. They also meet all requirements when it comes to their surface, which stands out with particularly high corrosive resistance.
Our line tubes are the first choice for applications where perfect corrosion protection is required. With the innovative ZISTA solutions, BENTELER Steel/Tube has developed an excellent surface protection for line tube.
- ZISTA CRF® - environmentally-friendly coating for precision steel tubes.
- ZISTA® SEAL - even better corrosion protection after forming thanks to an additional sealing.
- Zistaplex® - solution for the most demanding property profiles with highest corrosion protection due to additional organic coating.
Our produts benefit from very good bending and forming properties and stand out through good adhesion and high ductility. What is more, they satisfy the requirements of standard screw joint systems in an optimum manner.
The new product HPL500 combines higher fatigue resistance with good formability. As an outstanding solution HPL500 is the key to reach higher performance in hydraulic systems. The improved mechanical performance bears potential for significant weight reduction, increased flow rates as well as higher pressure rates to gain efficiency.
