Buffer tanks from Eugen Büdenbender GmbH & Co. KG are drawn and manufactured individually according to your specifications. We give you not just standard tanks, but customized solutions for your needs. We are flexible in terms of diameter and overall height, and we also create stratification systems precisely to your instructions – whether you need nozzle pipes, pipe bends, baffle plates or divider plates. If desired, our buffer tanks can be equipped with a manway opening for maintenance access, and can also be coated inside and out depending on your requirements.

We can also deliver tanks with optional insulation. It does not matter to us whether you need soft foam insulation for the interior or mineral wool insulation with a steel jacket for outdoor insulation.

Our buffer tanks are manufactured for customer specifications; each tank is made based on a custom drawing.

All of our buffer tanks are calculated and manufactured according to the AD2000 code, even if they fall under DGRL 2014/68/EU [Pressure Directive] Art. 4.3. Therefore we can also easily deliver the buffer tanks with a CE mark if you wish.

At your request, in addition to working with the pre-testing departments of the notified bodies and with various engineering offices, we can also create additional calculations for your buffer tank such as proofs of stability for earthquake zones or for wind loads, nozzle loads or wave loads.

 

The most important key data for our pressure vessels:

We process all of the common materials used in boiler construction. In addition to working with carbon steel, we can also retool our manufacturing workstations for stainless steel and make all of our tanks in stainless steel for you. We process materials such as

  • P265GH
  • S235JR+N
  • P235GH
  • P250GH
  • P355NH
  • 1.4571
  • 1.4404
  • 1.4541
  • 1.4301

In addition, all of our tanks can be made from equivalent ASME materials (e.g. SA516 Gr. 60).

A major advantage of our manufacturing process is the ability to flexibly handle a wide range of wall thicknesses. For instance, our manufacturing range includes a 100-liter tank with a 5-mm-thick wall as well as a large tank with a capacity of 80,000 liters.

 
  • Wall thicknesses from 4 to 20 mm
  • Pipe diameters up to 3200 mm
  • Tanks up to a unit weight of 12 tons

Thanks to modern calculation programs, we can determine the necessary wall thicknesses for your pressure tank right away during the bidding phase. That allows us to properly design and precisely calculate the tank parameters according to your wishes during the project phase. We design and calculate all pressure tanks according to the AD2000 code or EN 13445.

If we are awarded a contract, the drawings we create and our auditable calculations are then submitted to the notified body (e.g. TÜV) and previewed. For our customers, this service is included in the total price of the tank. Like the pressure test, it does not involve any additional costs for you.

All pressure tanks from Eugen Büdenbender GmbH & Co. KG are individually designed, drawn and manufactured. That means you can review every nozzle position and connector size before the start of production, and adjust them to your specifications at the construction site. Because we are a family-run company with a long tradition, you benefit from our flexibility. Do you need to make changes to nozzle positions or add mounting parts such as pipeline holders at short notice, even though the tank is already in production? We always try to fulfill our customers’ requests, and we can make quick changes even during production.

Optional: insulation

We can also deliver tanks with optional insulation. It does not matter to us whether you need soft foam insulation for the interior or mineral wool insulation with a steel jacket for outdoor insulation.

Contact us! Together with our partners from the region we can offer insulation for your needs.
