Stainless steel hydraulic tanks for machines, plants and vehicle technology

Stainless steel hydraulic tanks are integrated into the hydraulic system of machinery, equipment and automotive engineering (vehicles). Hydraulic systems transmit power, energy and signals. The whole thing works with a fluid, usually hydraulic oil. Stainless steel hydraulic tanks act as storage and extraction points for the hydraulic oil within the system.

Stainless steel hydraulic tanks must meet regulatory requirements as well as numerous other requirements. In daily use, stainless steel hydraulic tanks are constantly challenged by mechanical stresses, vibrations and temperature differences. Strength requirements are additionally increased by complex shapes for maximum filling volume.

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

Manufacturing process

Manual welding
As a specialist welding company, we can draw on many years of know-how in welding technology with our trained personnel. Stainless steel hydraulic tanks are manufactured using an automated welding process and are also welded by hand. Especially for custom-made products and small to medium-sized series, we like to use the manual welding process as a cost-optimized alternative with fast throughput. We manufacture hand-welded stainless steel hydraulic tanks on innovative welding tables. Our own fixture construction ensures dimensional accuracy and lasting precision even with high tolerances.

Automated welding
The automated welding process is carried out with state-of-the-art welding robots. The automation allows a very fast and efficient production. This is particularly profitable in the case of high demands that are to be produced at low costs while maintaining consistent quality. The automated welding process represents a method of welding with extremely high precision. This means that even complicated stainless steel hydraulic tanks with high tolerance requirements can be implemented.

Manufacturing process

Corrosion protection and finishes for stainless steel hydraulic tanks

Surface treatments improve the durability, safety and appearance of stainless steel hydraulic tanks. A permanently corrosion-free, safe and solid surface extends the service life and visually enhances the stainless steel hydraulic tanks. Our own powder coating and painting facility ensures this quickly and in high quality in all RAL colors. Heat-resistant painting, powder coating, pickling or passivation provide excellent protection against corrosion.

To ensure that the test phases and the use after commissioning of your product by your customers run smoothly, we secure you with FEM calculations already in early development phases. Among other things, we determine the structural strength, fatigue strength and material efficiency of your concept. In doing so, we digitally illustrate the effects of various mechanical, thermal and electrical stresses by means of linear and non-linear structural-mechanical calculations. This enables us to examine the effects of the various influences on the entire product or component for both simple and arbitrarily complex geometries before we build prototypes.

The results of these calculations are additionally useful to you as a certificate for technical approvals, for product liability and production releases.

NovaNox FEM calculations are performed analytically according to general and international standards. This ensures the comparability and reliability of the 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 produce technical drawings for you in 2D (in dxf, dwg and pdf formats) and in 3D (in step format). This includes individual part drawings, assembly drawings, general drawings or assembly drawings as required. In addition, detailed technical documentation is included for your review. This allows you to make any adjustments or special requests in good time before the start of production.

This gives you the certainty that everything will fit perfectly and be implemented error-free when production starts. With this scope of technical drawings including the comprehensive documentation, communication functions smoothly throughout your entire development and production process chain. Each stage receives the information relevant to it, making processes much more efficient.

You will be involved in the project planning, design and selection of construction, material and manufacturing process from the very beginning. In this way, we want to ensure that a result as close to series production as possible is already achieved in the prototype phase and that your time and cost planning is adhered to.

The results of the FAI are analyzed in order to trim the manufacturing process to the highest possible efficiency and cost-effectiveness. To this end, we support you in significantly reducing the time-to-market and starting successful series production on schedule. In this way, we keep within your project budget and you have more security.

To ensure that your production runs without interruption, we take care of the entire process for you, from demand planning to logistical handling. For this purpose, we have a total of 1,200 square meters of storage space available to you as a consignment warehouse. This saves you costs in warehousing and in production due to larger batch sizes.

Your uninterrupted component supply for series production is guaranteed. Your stainless steel hydraulic tanks are delivered on schedule from the consignment warehouse as required. We fully integrate your existing logistics processes. The secure component supply with stainless steel hydraulic tanks from NovaNox® is thus optimally solved throughout the year.

Quality management

Based on the welding process planning, the most suitable welding process is selected for the individual requirements of your stainless steel hydraulic tanks. The right process increases the safety and stability of your stainless steel hydraulic tanks.

Welding process planning determines the welding sequence. The optimum sequence of welding operations is just as crucial for more efficient production processes as it is for a longer service life and reliable leak tightness of your stainless steel hydraulic tanks.

Type identification makes it easy for you to trace each stainless steel hydraulic tank back to its source. The entire path from production to the last use can be traced in detail over the entire product life. A record that gives you greater security.

Depending on the material and stress on your stainless steel hydraulic tanks, various types of type markings are available:

  • 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

Your personal identification is composed of symbols, numbers or letters. This means that every stainless steel hydraulic tank can always be traced. This is the clever integration solution for optimum, unambiguous route and process reconstruction!

The leak test provides proof that your stainless steel hydraulic tanks remain absolutely leak-proof even in continuous operation and under extreme conditions. This process from the quality management area gives you additional security, because you receive the leak test for each delivery as a written declaration of conformity, if you wish. This NovaNox® test certificate is quickly and easily incorporated into your overall documentation. We carry out these leak tests for you:

  • In accordance with ECE R34 or 70/21/EEC regulation, we execute a 100% test with air underwater in our specialized test basin
  • Pressure test
  • Leak test by means of red or fluorescent dyes
  • Ultrasonic testing

To ensure the high quality of your products, quality assurance in production through accurate recording of production processes is essential. Complete documentation also brings enormous cost savings, especially for large projects. This is because errors and quality deviations are detected and corrected at an early stage.

Precisely documented, repeatable processes give you more time and free up personnel capacities. 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 documents can be easily and quickly sorted into your overall documentation.
