Telescopic bushings are a very important and responsible element of the steam admission system in the steam turbines due to the extreme operating conditions (even 540 °C, 20-30 MPa). The seal typically consists of a set of multi-edge seals to seal the coaxial portions of the intake pipeline. The reason for using such a solution is the possibility of installing the inner casing in the outer one, as well as compensation of thermal expansion of the elements. This time, the task was to machine heavily worn-out sleeves to new diameters. While stationary machining of such an element is trivial, fulfilling the design requirements of machining in the mobile version, including […]

We finished the work on the modernization of the gas turbine, where our task was a.o. very difficult drilling for the casings’ retaining elements. The problem we had to face is the difficult position of drilling – on the edge between two different materials, with a step or drilling into the halve of the old hole. Since the holes were arranged around the perimeter, some of them were also drilled in the ceiling position.

We are pleased to announce that from April 2020 we are cooperating with WENA Consulting in the field of Environment, Health and Safety, fire protection and preliminary and periodic trainings and dedicated to specific topics e.g. first aid, support of AED defibrillator, etc. More information: https://wenakonsulting.pl/

We are proud to inform you that our Company has obtained the system certificate at Occupational Safety Management ISO45001.This standard helps organizations manage processes and risks related to health and safety at work in a systematic and consistent manner. ISO 45001 replaces OHSAS 18001 (in Poland PN-N 18001), which will be discontinued on March 12, 2021. This means that by then, all organizations that currently have a valid OHSAS 18001 certification, for continuity, are required to update their system to the requirements of the new version of ISO 45001. Iso 45001 certification is a reliable proof that all processes implemented in our organization are oriented towards ensuring safe working conditions. […]

Dear Customers, we are changing the invoicing address to Tumlin Dąbrówka 68a, 26-050 Zagnańsk. Other data remain unchanged.

Due to the projects implemented for the shipbuilding and offshore industry in the European Union, we underwent certification by the Classification Society – Registro Italiano Navale. The competences confirmed by the RINA certificate allow us to participate in projects which due to the maritime specificity and related regulations must be supervised and approved by the Classification Society. The certificate confirms the suitability of our technologies for marine applications. Registro Italiano Navale (RINA) – an Italian classification society founded in 1861 as Registro Italiano, with headquarters in Genoa. After merging with the competitive Registro Nazionale in 1910, it operated as the Registro Nazionale Italiano, and from 1922 as the Registro Italiano […]

This time we present the FAROARM ™ QUANTUM measuring arm and its applications. The arm allows to measure of length and angle as well as deviations in shape and mutual position, both for material and abstract objects – such as, for example, axes of holes, theoretical shape, etc.

The main aspects of turning surfaces of cylindrical drums, shafts and journals are:

The deadlines are always tight. To meet the schedule, sometimes one needs to work not only 24/7, but also double the machining capability. We can take up such challenges thanks to the large WWTECH equipment base. The pictures show two Circular Mill (CM6200) milling machines. More about the CM6200 in the video

Sometimes there is a need to do something untypical, custom. This time it was about making “deepenings” in the ribs of a large rotary element.
