Our services

Complete care for the condition of your equipment

NDT inspection using the ET method

We collect data from heat exchangers during maintenance outages. The data are analysed using the eddy current (ET) method with bobbin probes, special techniques (X-probe) and rotating probes (MRPC).

Eddy current data analysis

ET data are collected by qualified personnel on an agreed number of exchanger tubes, with a focus on detecting tube wall thinning.

Pulsed eddy current (PEC)

We assess the condition of insulation and corrosion under insulation without removing it, using pulsed eddy current (PEC) with Eddyfi LYFT and REDDY technologies.

Storage tank inspection

We verify the serviceability of tanks using the MFL and STARS methods with Eddyfi FloormapX technology, even while the tank remains fully in service.

PScoat thermal insulation coating

We apply PScoat thermal insulation coating to pipework, valves and process equipment. It significantly reduces heat loss and protects staff from burns.

Welding and metalwork

We carry out metalwork and welding, including repairs to piping systems and the installation and removal of pipework on the units of the Dukovany and Temelín nuclear power stations.

Our NDT methods: VT, PT, UT, RT

Penetrant testing (PT) and visual testing (VT) are among the most widely used methods of non-destructive material testing and are well suited to detecting basic defects. The other methods focus on detecting and evaluating the condition (properties) of product materials using specialised instruments and equipment.

Administrative and quality control activities

This work is carried out by administrative staff who survey existing equipment on site, checking its technical condition and the location of all equipment and components within the nuclear power station. The information gathered is then digitised for further processing.

About us

Experience you can rely on

Zatist, s.r.o. was founded in 2017 and is based in Modřice near Brno. Our technical equipment enables us to carry out non-destructive testing (NDT) using a range of methods, and we also specialise in the full scope of the ET method, from data collection and analysis through to the final report. We employ specialists who are also qualified to work as trainers. We carry out welding and metalwork and provide a variety of NDT inspections during planned outages at nuclear, thermal and combined-cycle power stations, as well as at petrochemical and engineering plants, both during manufacture and before equipment is put into service. We deliver this work with both in-house and external personnel.

Our NDT personnel are qualified to ČSN EN ISO 9712 at Level 2 or Level 3 and are ready to step in during both planned and unplanned outages.

To achieve the best possible results when identifying corrosion and defects, our NDT reports are produced using state-of-the-art equipment from the world’s leading suppliers of ET technology.

Projects

Selected projects

Heat exchangers and steam generators in nuclear power stations

Eddy current data collection and analysis on steam generators and regenerative heat exchangers during planned outages.

MERO tank inspection

Verifying the serviceability of fuel storage tanks using the MFL method with FloormapX technology.

PEC measurement under insulation

Detecting corrosion under the insulation of process pipework without having to remove it.

PScoat thermal insulation

Applying thermal insulation coating to valves and pipework on hot water distribution systems.

Welding and metalwork at Dukovany NPP

Repairing PG26 collector bridges, start-up work during a critical repair and delivering repairs of heterogeneous (HTG) welds on the steam generator feedwater system.

Technical inspection of an energy company

We mapped and inspected the external condition of the site through a walk-through survey, recorded the actual condition of the technical equipment and compared it with the as-built documentation.
