Tank construction

Stainless steel pressure tanks

We carry out welding tests for pressure tanks, mainly in the food industry. The surfaces of the parts in contact with the product can be up to 0.5 mm.

  • Stainless steel from Ø 300 to Ø 1500 mm
  • Individual lengths up to 3000 mm,
  • Sheet thicknesses from 1.5 to 6.0 mm (depending on the diameter),
  • Steel from Ø 300 up to 3000 mm,
  • Individual lengths of up to 3000 mm,
  • Sheet thicknesses from 1.5 to 15 mm (depending on diameter)

Common welding methods (TIG / Mag / Pulse / SAW) are used.

Tank construction/metal construction

Pipe production

Stainless steel tube production at Nießing is characterized by special dimensional accuracy. Particularly thin-walled designs start from 1.5 mm thickness and can be scaled as required.

Nießing’s stainless steel tubes for exhaust gas, process air and exhaust air ducting are corrosion-resistant.

Tank construction/Metal construction

We mainly produce racks for the food industry. Welding approval according to 1090-2 EXC3 and the corresponding welding tests are available. All common materials like steel, stainless-steel and welding methods (TIG / Mag / Pulse / SAW) are used.

Tank construction/Metal construction

Custom-made designs

One of our area of specialty is the production of steel and stainless-steel components, which our customers require in various qualities / material grades for their projects. This includes laser / flame cutting or precision edging and rolling. Common welding methods (TIG / Mag / Pulse / SAW) are used.


Diverse customized solutions


Exhaust silencers

Operators of power plants are required to comply with relevant environmental regulations, for example noise levels. Nießing treats the exhaust system – from the outlet of the power generator (boiler, engine, ...) to the chimney orifice – as a complex unit during acoustic testing.


SCR catalytic converter/SCR silencer combination

Compared to conventional systems, Nießing’s silencer-SCR unit features a more compact design for minimal space requirements; a lighter construction thanks to special components; as well as an increased efficiency for maximum noise reduction.


Plant construction/Steel chimney construction

Nießing always literally outgrows itself when it comes to plant construction: Be it supply or exhaust air towers, steel chimney construction or turnkey exhaust air/flue gas systems - Nießing carries out the engineering, planning, construction, commissioning, monitoring and maintenance of industrial chimney systems that direct both supply and exhaust air in the right direction.
