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

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-
