HEAT TRANSFER

We offer one of the most comprehensive steel tube portfolios for all kinds of modern energy production and the corresponding auxiliary units. We also supply products for applications in the chemical and petrochemical industries. Our tube products are distinguished by maximum pressure and heat resistance, strength and durability.

Boiler tubes: highly coveted
For the use in oil-fired, coal and gas power stations, we offer tubes with a heat resistance of up to 620° C. What is more, we also offer tubes with an internal or external profile that ensure ideal heat transfer thanks to their unique internal geometry. At request, we supply steel tubes with a length of up to 23 meters for heat recovery steam generators (HRSG) of gas-fired power stations and produce complete serpentine tubes for superheaters.

Heat exchanger tubes: universal application
Our heat exchanger tubes not only convince through their universal usability. As straight tubes, we can supply them in a length of up to 25 meters. Our fully automated U-tube production allows for the tightest bending radii and precise geometry.

 

Multi-lead rifled tubes: cost-reducing
Our optimized Multi-Lead Rifl ed Tubes used at a lead angle of 40° in vertically tubed special boilers ensure efficient boiler technology. With their sharp-edged rifle profile, they create an optimum flow pattern, reduce construction costs and provide for a significantly lower steam throughput. For application in fossil power plants, we also supply seamless, cold-drawn Multi-Lead Rifled Tubes with a lead angle of 30° for spiral-tubed boilers.

 


Serpentine tubes: individually processed
Our serpentines made of alloyed steel, which are used in special high-pressure preheaters, are suited for solar power plants with an output of more than 500 megawatts. Formed and bent according to individual specifications, they provide for a more compact design and more flexible operation. Moreover, they reduce maintenance requirements, optimize power plant control and extend the service life of high-pressure feedwater heaters.
