Pipe production

Stainless steel tubes for exhaust air

Stainless steel tube production at Nießing is characterized by special dimensional accuracy. 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-proof.  Shaping is done using our rollers. The pipe section is then welded on the longitudinal welding machine.

Nießing’s steel pipe production accurately meets the requirements for a durable connection. Be it the production of steel or stainless-steel tubes. With an extremely high manufacturing accuracy, all steps are carried out on schedule, to produce the necessary connections.

Thanks to many years of experience in chimney construction as well as outstanding quality in this area of production, both single pieces and large series are part of the program. For Nießing, the length is scalable, since the welded pipe pieces can be joined together.

Nießing steel pipe production is designed for the following dimensional ranges:

  • For diameters up to 3,500 mm
  • For plate thicknesses up to 20 mm
Tank construction/metal construction

Tank construction

Nießing’s stainless steel tanks meet the highest requirements for precise execution. Here, special welding processes for notch-free through-welded seams are used. The tanks are pickled, sanded and polished.

Tank construction/Metal construction

We mainly produce racks for the food industry. Thus, the welding approval according to 1090-2 EXC3 and the corresponding welding tests are available. Common materials like steel, stainless-steel, as well as the 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.


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.


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.
