It happens that the thread is damaged by disassembling the blocked bolt. In most cases, it is relatively easy to recover the full functionality of the connection. The approach to repair depends on many factors: location, degree of damage, size, weldability of the material, etc. Apart from the cost and time of reconstruction, all these factors must be taken into account when choosing the method of repair. We have recently been asked to reproduce the functionality of a threaded hole in the steam turbine body. In order to avoid mistakes in the future, the customer decided to keep the current thread size – hence the sleeve was selected as the […]

The shipbuilding industry in Poland does not look as bad as it is commonly thought. Polish private shipyards, in particular, build more and more complex ships, adding more and more added value, competing as well as cooperating with global giants such as Scandinavian ones. We have recently participated, of course adequately to the nature of our activity, in the construction of a crucial piece of specialist equipment for the ship for laying undersea pipelines. This is a giant spool, used for transporting and laying a prefabricated pipeline (or, for example, an energy cable or optical fiber), which is simply wound on it. The spool is several meters in diameter and, […]

How important are the foundations, you do not have to convince anyone. Especially if they are foundations on which complicated devices and machines will be placed. It is important that the pressure resulting from the weight of the seated structure is evenly distributed – to achieve this, bearing surfaces – foundation slabs – must meet structural requirements such as the mutual position of individual panels – determined by the permissible deviation of the relative height (max 1 mm) and maintaining the level and flatness of each foundation slab (max. ± 0.05 mm / m). The following are examples of foundation slabs (milling of large planes) and completed plate with measurements […]
