Hydropower Plant Murkraftwerke Graz
In March 2017, ANDRITZ HYDRO begins supplying electromechanical equipment for a new hydro plant in the heart of Graz, the capital of the Austrian province of Styria. The start-up of the power plant is planned for the first half of 2019. Before the construction is completed, it is necessary to install the power plant equipment: turbines, generators, flaps, various types of drives and control systems. And here is the place for our services. Of course, as in a hydroelectric power plant, the main task is to process large-size flanges. It is a very avant-garde design, which can be seen in the following visualizations: More about the plant: The current state indicates that there is still a lot to be done. As usual, the work begins with accurate measurements. In the foreground, the measurement head of the Laser Tracker device, and the measured object deep in the background, behind the scaffolding. Initial setup of the machine at the workplace. Centering the machine using Laser Tracker. View from the top Machine ready During machining… Finished. Time to change the configuration – to process a larger flange in the same mounting Continued processing. This time the outer collar Time for a change, we move to a new processing place. Re-installation of the machine. As usual, under the supervision of Laser Tracker ™. Ready. Machine tool ready to work. Already during the treatment, it turned out that the surface damages of the workpiece are too deep. The customer decides to fill the cavities with padding. Here is the result. We continue processing Finished. Now a short rest and then the same next – on block 2. Note: the above photojournalism does not contain a description of the complete sequence of activities but only selected stages of work. All activities were performed in accordance with health and safety regulations.
The workshop metrology
Well-made measurements – quickly, accurately, repetitively – are a necessary condition of successful project. Two things are necessary for this: appropriate measuring equipment; trained and experienced staff. The measuring equipment must meet a number of requirements related to the nature of the work: most often there are remote measurement, resistance to humidity, dustiness and temperature changes. These requirements are met by Laser Tracker ™, which we use in our work. The measurements can be systematized as follows: For the needs of mobile machining: Before machining: initial dimensions and dimensional analysis – determination of allowances, determination of axes and theoretical points, marking out; During machining: dimensional inspection, necessary adjustments, forecasting of work progress; After processing: final dimensions, reporting; Metrological assistance: The service consists in performing measurements for disassembly and assembly works, including mobile machining; Assistance may cover the whole period of activities on the site; The result is ad hoc reports and recommendations as well as a final report. Standalone measurement: Standalone measurement of indicated dimensions, which results in a measurement report or geometry mapping of the object in the form of a CAD model.

Heat exchanger in chemical plant
Chemical Industry is very demanding customers. We are therefore glad that we are often chosen to carry out mobile machining services on elements of chemical installations. In this case, it was a heat exchanger on which we made three treatments: facing the face of the flange connection of the bottom of the heat exchanger and planning the face of the outlets together with machining the groove for the RTJ type seal (RT). While flanges planning is typical, routine work, the groove for the steel seal is a challenge – the requirements for dimensional accuracy and surface quality are much stricter than for other treatments. Confirmation of the right parameters of the groove is “blue print check”. The machining of the outlet flange with a trapezoidal groove for the steel gasket. Starring: Climax FF6200 lathe for the flanges. The machining of the outlet flange with a trapezoidal groove for the steel gasket. On the left side, finished – flange ready . The blue perimeter strip is the mark of the blue print check. Flange on the right during machining. Machining of the bottom of the exchanger – the same machine can handle a wide range of diameters: 508 to more than 1270 mm (20 – 50″) More information about the equipment and machining of flanges: https://wwtech.com.pl/en/on-site-machining/boring-and-turning-using-portable-machinery/machining-of-flanges/ More information about flange facer FF6200:
In an unusual scenery reminiscent of the Star Wars droid factory, a small project for the implementation of a new splineway was carried out recently. During the exploitation it turned out that the sunk key connection is destroyed, and the current groove in the shaft so permanently deformated that it can no longer fulfill its role. (more…)

Works on a special ship – a floating platform – in one of the Polish shipyards
We have recently completed the provision of services for the construction of a ship to service drilling platforms – a floating platform. The ship was built in Poland for the German-Spanish shipowner, with our modest participation. In the scope among otherscoaxial boring of various sizes of holes and milling of large flat surfaces.

Fully functional equipment is fundamental to company’s success. Every machine has precision elements, bearings and number of other parts, that enable its efficient operation. Those main elements, which ensure correct machine operation require specific solutions in case of a breakdown. Leaks, cracks and grooves are issues that have to be eliminated to ensure proper operation.
An industrial metrology
WWTECH Company provides its clients with a complex way of problems resolving, offering them three-dimensional coordinate measurements and a full 3D documentation. Due to accurate measuring devices FARO (Laser Tracker, Measuring Arm) WWTECH makes it is possible to carry out uniquely accurate, fast and non-contact measurements, results of which can be analyzed in a real time.
In all undertaken activities WWTECH gives priority to the safety. Our staff’s and the society’s health, respect for the environment are the factors which determine a whole tam activities, a place and other aspects of our work, such as transportation or cooperation with a third party.
