STEINSERV: Service for Power Plants – for more than 20 Years
For more than 20 years, STEINSERV has been offering solutions for the modernization, modification, and repair of pressure part components in conventional power plants, waste-to-energy plants, and other industrial sectors utilizing boiler systems.
We are one of the most experienced suppliers of cladded and non-cladded tube-fin-tube membrane walls, as well as inlet distributors and outlet headers for pressure parts, including high-pressure applications.
Pressure part welding technology – both in our own manufacturing facility and on-site in boiler systems – is one of our core competencies. Highly qualified site managers, along with assembly teams consisting of welders and plant fitters, complement this portfolio to provide a complete, all-in-one package.
With our own engineering and design department, as well as in-house manufacturing and assembly, we are capable of responding to our clients’ individual challenges and delivering tailored solutions.
We have won over our long-standing customers through the experience, expertise, and motivation of our employees.
