Range of goods: gland packings, sealing sets and flange packings operating under the most severe conditions, metal gaskets, high-quality metal seals, hydraulic components, sealing cuffs, bearing insulators, mechanical seals, pneumatic seals, thermal expansion compensators.
Radiation-resistant video observation systems
Inkla offers design and manufacturing services for electronic systems and their components for use in unfavourable ambient conditions with high levels of radioactivity, such as for example radiation-resistant reactor vessel video observation and monitoring systems operating under severe conditions.
Our company supplies radiation-resistant equipment and industrial TV and radiation condition monitoring systems for NPPs. Timely detection of leaks and other faults in the functioning of equipment located in enclosed rooms has always been an important part of ensuring the safe operation of nuclear power generation facilities, and following the accident at the Fukushima NPP, continuous remote monitoring has taken on particular significance.
The radiation protection technologies we supply, which are used in well-lit, compact radiation-resistant chambers, are protected by patents and are passed for use in maximum design accident conditions.
Besides radiation-resistant chambers, our company supplies special dosimeters. When they are set up in the main equipment zones of an NPP, the process of measurement of the accumulated dose takes place over the course of several years. Use of dosimeter information data enables proof to be provided to the nuclear regulator of the potential to extend the service life of important equipment. The systems supplied have demonstrated good reliability and simplicity of operation.
