Steel hydraulic tanks for machinery, equipment and vehicle technology

Steel hydraulic tanks are embedded in the hydraulic system of machinery, equipment and automotive engineering (vehicles). Hydraulic systems handle power, energy and signal transmission. Hydraulics are operated with a fluid - usually hydraulic oil. Accordingly, steel hydraulic tanks are the containers in which the hydraulic oil is stored and which are used for extraction.

Steel hydraulic tanks have to comply with legal regulations and meet many other requirements. In daily use, steel hydraulic tanks are constantly exposed to mechanical stresses, vibrations and the ups and downs of temperatures. Complicated designs for maximum filling volumes place additional demands on strength.

We only produce individual solutions for orders of at least 50 pieces

Lightweight steel hydraulic tanks from NovaNox®.

Unlike common steel hydraulic tanks, lightweight NovaNox® hydraulic tanks are made of high-quality thin sheet steel. This feature allows significant weight savings. This is particularly attractive for automotive and aerospace applications because the weight reductions reduce both fuel consumption and the resulting operating costs.

Even in lightweight design, our steel hydraulic tanks made of thin sheet have high stability as a quality feature. Our in-house welding process planning is responsible for this.

Manufacturing process

Manual welding
As a specialist welding company, we have experienced personnel and many years of practical knowledge in welding technology. We manufacture in the automated welding process and also hand-welded steel hydraulic tanks. The manual welding process is a cost-effective alternative with fast turnaround times, especially for custom-made products and small and medium-sized series. The hand-welded steel hydraulic tanks are finished on modern welding tables. Our in-house fixture construction guarantees dimensional accuracy and permanent repeatability even with high tolerances.

Automated welding
We have state-of-the-art welding robots for the automated welding process. The automated manufacturing process makes production very fast and efficient. This favors the cost-effective production of high requirements with consistent quality at all times. As the most accurate welding method, the automated welding process achieves the highest possible precision. This means that even very complex steel hydraulic tanks with high tolerance requirements can be manufactured.

Corrosion protection and finishes for steel hydraulic tanks

Surface treatments increase the durability and safety of steel hydraulic tanks and improve their appearance. A corrosion-free, safe and solid surface in the long term promotes durability and gives the steel hydraulic tanks a more attractive appearance. Our own powder coating and painting facility promptly realizes surface finishes in all RAL colors to a high standard of quality. For optimum corrosion protection, heat-resistant paints, powder coatings, pickling and passivation are all possible options.

We use FEM calculations to determine the structural strength, fatigue strength and material efficiency of your concept, among other things, as early as the initial development phases. This puts you on the safe side during the test phases and also after your customers have put your product into operation. Our digital representation shows you the consequences of a wide range of mechanical, temperature-related and electrical loads based on linear and non-linear structural-mechanical considerations. The advantage for you is that we can examine the effects of the various influencing factors on the entire product or component even before we build prototypes. And we do this for a wide variety of geometries, including highly complicated ones. This reduces the time required and the overall costs and increases your safety.

The results of these considerations provide you with evidence for technical approvals, product liability and production releases.

General and international standards are the basis for the analytical FEM calculations of NovaNox®. This guarantees comparability and reliable results. In detail we do for you

  • linear and non-linear structural mechanics calculations
  • Analysis of deformations, stiffnesses and stability
  • Consideration of natural vibrations
  • Transient structural analysis
  • Collision analyses
  • Temperature field calculation (thermal-stationary or thermal-transient)
  • CAE-supported fatigue analysis with nCode

We provide you with technical drawings in 2D (in dxf, dwg and pdf formats) and in 3D (in step format). We will produce individual part drawings, assembly drawings, general drawings or assembly drawings for you as required. In addition, you will receive detailed technical documentation for review. This allows you to make corrections or add individual requests before the start of production. In this way, you can be sure that everything will fit perfectly and be implemented error-free at the start of production.

With these comprehensive technical drawings and integrated documentation, communication runs exactly through your entire development and production process chain, making the overall process more efficient. This is because the different information requirements of each stage can be met in a convenient way.

Already in the prototype phase, we strive for a result that is as close to series production as possible. This enables us to achieve the best results and to meet your time and cost planning more reliably. That's why we work intensively with you as early as the development, project planning and definition of the design, material and production process.

Finally, we analyze the FAI results and refine the manufacturing process to achieve the highest efficiency and cost-effectiveness. In doing so, we assist in drastically reducing the time-to-market and ensure a scheduled and successful start of series production. You thus save your project budget and achieve the highest possible security.

From demand planning to logistics, we relieve you of the complete process. To ensure uninterrupted production processes, we can provide you with a total of 1,200 square meters of storage space as a consignment warehouse. This saves you storage costs compared to your own storage capacities and allows you to produce more cost-effectively in larger production volumes.

In this way, you ensure the best possible component supply for your series production. Your steel hydraulic tanks are delivered on schedule and flexibly on call from the consignment warehouse. We fully integrate your existing logistics processes and thus enable your secure component supply with steel hydraulic tanks from NovaNox® throughout the year.

Quality management

Welding process planning is the basis for determining the optimal welding process for the specific requirements of your steel hydraulic tanks. The right process is crucial for the safety and robustness of your steel hydraulic tanks.

The welding sequence is also worked out and determined in the welding process planning. The most efficient sequence of welding operations increases the efficiency of your manufacturing operations. It also ensures a longer service life and reliable tightness of your steel hydraulic tanks.

Type identification makes each steel hydraulic tank easily traceable to its source. Every step from manufacture to the last application can be verified in detail over the complete product life. This verification means even more safety for you.

Depending on the material and use of your steel hydraulic tanks, different types of type markings are possible:

  • Laser engraving
  • Welded metal plates with laser engraving
  • Self-adhesive metal plates with laser engraving
  • Self-adhesive plastic plates with specific imprint and silicone coating for external protection

You can mark your steel hydraulic tanks individually with symbols, numbers or letters. With this personal identification you achieve consistent traceability and an integrated, clear path and process reconstruction!

The leak test as a process from the quality management area ensures that your steel hydraulic tanks remain absolutely leak-proof even in continuous use and under the most challenging conditions. As additional security, we are happy to provide you with the leak test as a written declaration of conformity for each delivery. You can easily include this NovaNox® test certificate in your overall documentation. We carry out these leak tests for you:

  • Our dedicated test basin is employed for a 100% test with air underwater, conforming to regulations such as ECE R34 or 70/21/EEC
  • Pressure test
  • Leak test by means of red or fluorescent dyes
  • Ultrasonic testing

Precise documentation of production processes is essential for quality assurance in manufacturing. It ensures the quality of your products.  Complete documentation also creates remarkable opportunities for cost reductions, especially in large projects. Because errors and quality deviations can be detected and eliminated very early in the process.

Exactly recorded, repeatable processes free up additional time reserves and personnel resources. We offer you this comprehensive documentation for quality management:

  • Initial sample inspection report according to VDA 2, EN 9102
  • Factory certificates 3.1 and 2.2 according to EN 10204
  • Dimensional report by 3D measuring technique (Faro measuring arm)
  • Declaration of conformity for pressure tests

All our certificates can be easily integrated into your overall documentation.
