Tubes for industry applications
Solutions that function perfectly
Safety, stability, weight reduction. In the construction industry, these are the factors that count. In hydraulics and precision engineering, on the other hand, tight dimensional tolerances, ability to withstand high pressure, consistent production quality and corrosion protection are also important.
We provide specific solutions for an extremely wide range of applications with a variety of special requirements. Whether it’s mechanical engineering, for agricultural machinery, construction machinery or in the field of infrastructure and crane construction, our seamless and welded quality steel tubes offer ideal properties for optimal additional processing.
A range of high-performance products means complete success
High pressure, intense mechanical stress? It’s not a problem for our seamless and welded steel tubes. They make their mark with precise geometry and optimal material properties. The right coating protects them perfectly against corrosion where necessary.
Tubes for cylinder production
Smooth inside, tough outside
High cold ductility, consistent quality and good internal surface properties – ideal properties for cylinder production. Internally, our tube products have minimal roughness, particularly close diameter tolerances and customer-specific machining allowances – ideally suited to additional processing. In addition, you benefit from our long process experience with skived and roller-burnished tubes. Even if they need a finish.
Lightweight custom made
Our high-quality piston tube solutions offer great weight-saving potential as an alternative to solid bar. Thanks to our know-how, we also achieve tight dimensional tolerances and low ovality of the piston tubes. Moreover, they offer high straightness and low roughness.
Our protection for your tubes
Perfect corrosion protection is frequently called for in hydraulics. Our line tubes have the ideal finish for this thanks to innovative ZISTA solutions. We’ve developed several variants of this excellent surface protection for line tubes: ZISTA CRF®, ZISTA® SEAL Zistaplex® and Doppelzista. Our tubes can also be bent and formed very well and also impress with their good adhesion and ductility.
- ZISTA CRF®: the particularly environmentally compatible coating for precision steel tubes
- ZISTA® SEAL: additional sealing for better corrosion protection, even after forming
- Zistaplex®: our solution for the most demanding property profiles with even higher corrosion protection thanks to an additional organic surface layer
- Doppelzista: the answer when you also want to protect the inner surface of the tube.
Material solutions for hydraulic line tubes
Unremitting in operation
Better performance in hydraulic systems? No problem. Our HPL500 combines higher fatigue strength with good formability. Its better mechanical properties allow a significant weight reduction and higher flow rates together with higher pressures and greater efficiency. The result: smooth operation.
The optimal solution for your process
Whether it’s for machine and plant construction, the manufacture of turned parts or in wind turbines: thanks to the optimum combination of geometry, machinability and strength, our steel tubes perform heavy-duty work in many different industrial sectors. It’s good to know that we supply our seamless and welded steel tubes in all common standards and steel grades that weld particularly well. And in a wide range of dimensions.
Steel tubes in mechanical engineering
Best performance and cost effectiveness
From steel production to finished tube – all from a single source. We continuously monitor all important process parameters and material properties. From coordinating the heat treatment, optimally adjusting lengths and determining close–to-final-contour dimensions all the way to application of the materials. Our easily welded steel grades and green pipes made from steels with excellent machinability meet international standards.
Steel tubes for the construction industry
Safe and stable with reduced weight: Pipes in the construction industry have to perform well. For crane construction or injection anchors, for example. To this end, we develop innovative materials and specific technical solutions together with our customers. We supply our tubes in special grades and constantly optimize them. For example, by reducing their weight and thereby the costs of the construction as a whole. You can also rely on individual logistics concepts and just-in-time deliveries.
The benchmark in the drilling industry
Whether mining, mineralogy, geothermal energy or infrastructure: our drill pipes are in continual use. And this in the most diverse soil formations worldwide. Our individually manufactured tubes have the lowest residual stresses coupled with extreme straightness. They convince with their high strength very fine tolerances. The services we offer along the entire supply chain even give us the flexibility in tailoring the individual chemical composition.
Innovative solutions for a wide range of applications
Happy campers, safe and sound
From the gas bottle to the stove, refrigerator and heating: Over the past five years, leading recreational vehicle manufacturers in Europe have installed more than 8,000 kilometers of our tube solutions. That’s longer than the distance to the center of the earth. Our ZISTAPLEX® tubes ensure carefree holidays!
Lifelines for powerhouses
Almost every second hydraulic line in a crane, excavator, tractor, combine harvester or truck is "made by BENTELER". With HPL500 we offer our customers a new, extremely efficient line tube for hydraulic systems. The durable material helps to save weight while reliably withstanding very high pressures.
