Membrane wall bending machine for MARTIN Caldeiras
Schwarze-Robitec delivers powerful machine to Portugal
Thermal waste treatment is a complex process. At the centre of the process is the boiler consisting of several tubes welded together to what is known as a membrane tube wall. Before those walls can be used in boiler construction, they first need to be bent. In early 2019, Schwarze-Robitec delivered an FL 2000 membrane wall bending machine to Portugal to perform this task with maximum precision. The machine enables MARTIN Caldeiras, a manufacturer of boiler spare parts and a subsidiary of Germany-based company MARTIN GmbH, to bend entire membrane tube walls up to 2,000mm wide in a single step.
To ensure a perfect fit with the boiler design and adjacent supply line segments in modern power plant construction, the membrane tube walls first need to be bent with millimetre precision. The Munich-based company MARTIN GmbH is therefore banking on the FL 2000 membrane wall bending machine supplied by Schwarze-Robitec, the leading expert for tube cold bending machines, for its Portuguese subsidiary MARTIN Caldeiras.
Process optimisation and operational safety
MARTIN GmbH designs and constructs waste-to-energy plants, while its Portuguese subsidiary specialises in the manufacture of boiler spare parts and in robot cladding. ‘We wanted to optimise our processes and bend the membrane tube walls directly on site at our own facility,’ says Peter Alpiger, managing director of MARTIN Caldeiras. Looking for a manufacturer of tube bending machines with good references, MARTIN GmbH turned to Schwarze-Robitec. The traditional German business is one of just a small number of companies that supply membrane wall bending machines. The machines in the Boiler & Power series are perfectly suited to the requirements of boiler and power plants. The 27-ton membrane wall bending machine FL 2000 offers maximum stability and durability. MARTIN Caldeiras uses the machine to process walls consisting of tubes with a diameter of up to 70mm and a wall thickness of up to 5mm. ‘Continuous and safe operation with zero downtime is of major importance to us,’ Alpiger underlines. That is why the membrane wall bending machine FL 2000 is the perfect choice – it is both efficient and powerful, and comes with an integrated remote maintenance service.
