1. Ultrasonic defectoscopic analysis
This analysis involves ultrasound scanning inside the materials, where it can be seen at depths of up to tens of millimeters. Using the laws of ultrasound reflection and refraction and interpreting the echoes produced by ultrasound results in defects that occur in materials and can not be seen with any other form of non-invasive laboratory testing and examination. The method is not dangerous and it practically replaces the X-ray or Gamma method which was dangerous and which has been used in the past, no longer endangering the examiner. It is easy to interpret thanks to the software.
The most important ultrasonic examination methods are TOFD and Phased Array. The main advantages of non-destructive automatic ultrasound examination over conventional ultrasonic examination and radiographic examination are:
- Speed and reliability (records continuously, no need for radiographic films, developer, development time and large irradiations, accuracy up to 300mm compared to examination with radiation that is not sensitive to large thicknesses);
- Safety and security at work compared to the radiation examination (we do not need evacuated personnel; we do not have radioactive sources);
- Costs are saved (accuracy of defects, easy to analyze with software, speed of examination, analysis and interpretation, gives the answer on the spot).
The advantages of combining TOFD and Phased Array examinations:
- TOFD is sensitive to all types of discontinuities, including volumetric ones.
- TOFD is not sensitive to surface discontinuities. This problem is solved by Phased Array which combined with TOFD examines the entire volume of 100% of the material surface, because this area is analyzed together with TOFD and together with Phased Array.
With multiple implications, the analysis responds to the need to know whether a repair is compliant or not, the need to know whether a forged or cast material or whether a weld was performed correctly or whether or not it is defective in manufacturing, the need to to know if the thicknesses of the material are the same after wear or if they still comply with the standards and norms required by the customer.
It is a non-invasive measure, with the possibility of interpretation on the site, on the spot, saving analysis time. The service brings safety benefits (the safest at present, there is no better non-invasive method than ultrasound) and economic benefits by saving subsequent costs.
2. Analysis of air quality and environmental comfort
Represents a measurement and interpretation of the gases, respectively the quality of the respirable air and the degree of environmental comfort for people, animals or working environment, in accordance with the standards in the field or required by the beneficiary.

Satisfy the need to protect people, animals or work environments. Satisfied the need for safety in the operation of machinery so that the lives of humans or animals are not endangered. Prevent accidents at work or possibly the accumulation of gases that are in potentially explosive environments.
The analysis brings operational, environmental safety benefits for exposed persons, for persons working near or with the respective equipment. Economic benefits in the sense that they prevent accidents at work or possibly the accumulation of gases that are in potentially explosive environments and that can cause physical or financial damage to the installation, personnel or business itself.
3. Analysis of the behavior and efficiency of the refrigeration system
With the help of measuring and control instruments used in the technique of industrial, commercial (food) or household refrigeration, any defects that do not comply with the standards and regulations in force or required by the customer can be detected.
The laboratory analysis will determine the cooling or overheating of refrigeration systems or heat pumps, vacuum measurement, leak detection (eg freon losses), temperature and humidity measurement.
The analysis brings economic benefits following the reduction of defects found and the energy efficiency recommended following laboratory measurements. Compliance or non-compliance with the legislation in the field of applicability and quality of the refrigeration installation is highlighted.
4. Energy efficiency analysis
It is a total solution for performance inspection, analysis and monitoring of heat pumps, air conditioning, refrigeration systems and water coolers, by monitoring day, night, season parameters, in different standards. An interpretation is made that will give a report with conclusions and measures to improve the operating parameters.
It satisfies the need for energy efficiency that is imposed by law and by the customer's standard, to frame an installation in parameters that are normal, not to endanger life and not to bring a high degree of wear of the one who serves it.
The analysis brings economic benefits, in the sense that savings of 30-40% can be made by streamlining energy, be it electrical, thermal or otherwise, by finding the defect, fixing or optimizing it on the machine. It brings benefits to the quality of life, in the sense that through this monitoring it is known where vibrations, noises or other defects appear and decisions can be made to improve or remedy sealing or sound insulation.
5. Thermography
Represents the non-invasive transposition of defects in the invisible to the human eye in the visible field, is non-invasive from outside to inside and indicates the presence of defects, with applications in thermal thermography of installations, cables, liquid leakage, infiltrations from electrical panels, inspections thermographic in the naval, aeronautical, etc. field.
Thermography allows you to reduce the time to detect defects without having to stop the equipment. Failure to detect faults in time leads to unscheduled shutdowns. It can replace up to 100% of the workmanship on disassembling equipment or an electrical panel to see if there is anything wrong or not. You can see from the outside the correct position of a cable buried in the ground, without the need for excavation to search. You can see an infiltration on a building, by waterproofing, exactly the position where it flows. You can see through the walls how to place a pipe or cable, if you can core or if you can drill holes.
It saves money that can go up to 100% of the eventual activity with the disassembly and assembly of the analyzed equipment, eliminates significant costs that can be hundreds or thousands of times cheaper. The waiting time is reduced and quick decisions can be made depending on the analysis report.
6. Examination with magnetic powders MT and penetrating liquids PT
Represents examinations by the method with magnetic powders MT and the method with penetrating liquids PT that highlight major defects of crafts, cracks and advanced corrosion.
With the method of magnetic powders, it is possible to detect discontinuities (eg cracks) on the surface or immediately below the surface of ferromagnetic materials. With the method of penetrating liquids, discontinuities on the surface of ferrous and non-ferrous
metals, plastics and ceramics, glass, etc. can be quickly detected, provided that the discontinuities are open at the examination surface. It is used to examine welds, cast or forged parts, used in the construction of ships, cars and airplanes, pressure equipment and storage tanks, etc. The difference is that this PT method can also highlight defects or discontinuities on the surface of materials that are not magnetizable.
These methods show surface defects that can be highlighted at very low costs. It is possible to know whether the installation continues to withstand operation, whether or not the chosen material can be used in the application tested by the laboratory or can highlight periodic checks required by the operating standards of the installations, be they pipes, containers or equipment in movement, fuselages of aircraft or ship's hulls, microscopic parts of thermonuclear power plants to be checked periodically.
The service brings savings benefits by replacing up to 100% labor, ensures compliance with the legal provisions of the tested objects, guarantees that until the next check the equipment can operate in the correct parameters indicated according to the standards or possibly by reducing the parameters to the parameters indicated by laboratory.
7. Scan surfaces in 3D
It is a very new and very safe method of 3D scanning of the surface subjected to laboratory analysis, in order to observe and analyze possible defects or corrosion that may occur microscopically in the material or on its surface due to the operation or action of external corrosive agents.
It is a very fast method of scanning on very large areas (hundreds or thousands of square meters per day) with interpretation and very fast result. The beneficiary gains valuable time and satisfies the need to view 3D defects found on the surfaces or objects tested, so that he can make the best maintenance or business decisions.
The beneficiary saves a lot of time due to the possibility of scanning on large areas in a short time. All scans remain archived and can be based on technical expertise.
8. Inspection of metal cables
Represents the analysis from the outside to the inside of a cable to highlight any defects in construction, use, aging of the cable. In general, this service refers to metal transport cables (elevators, cranes, gondola lifts, telesky) where safety is of utmost importance.
The analysis indicates the degree of wear of the cable, the need for safety of the installation, the economic need to know when and if a cable is being replaced (optimizing service life).
Provides human and industrial safety. The service brings economic benefits in terms of using the maximum degree of wear and tear to make investment, repair or replacement decisions.
9. Welding quality examination
Represents an analysis from the outside to the inside of the quality of a weld, of the filler material used in a weld, which must be within the standard limits imposed by the customer.
Satisfies the need to know whether or not a weld is allowed according to the European or American quality standard ASME, whether or not the joint is related to pressures or agents that will act (corrosion, friction or electrostatic charge).
The analysis offers the guarantee of welding and indicates that it complies with the regulations required by the customer, that it complies with those conditions of welding or casting or joining of metals in the respective machine or equipment. The service brings economic benefits before mounting the pipe outside or inside, installing a container for use, etc. in the sense that subsequently the costs are much higher if the welding did not last and must be resuded or, worse, replaced all equipment or installation ( explosions may also occur which may endanger personnel).
10. Eddy-current scanning
This testing technique plays an important role in quality control of components and equipment and more. Eddy-current scanning of surfaces is based on electromagnetic induction. It is a measure of laboratory analysis of any anomalies or defects that occur in a pipe, welded, closed or open, in a machine or process installation, cracks, cracks of metals or non-metals, in general of pipes. It is currently applied in almost all heat exchangers and is a measure that diagnoses instantly.
The analysis indicates whether the machine can still be used, whether the service life can be leaked and whether or not there is a defect when checking or repairing a machine or installation equipment. For new machines it is mandatory by standard to check all pipes, especially for process pipes that are used by heat exchangers, tubular, semi-tubular or multitubular.
It is a non-invasive measure and can be done on very large volumes and sizes. It does not involve other forms of preparation of surfaces or pipes subjected to laboratory analysis, shortens the duration of data interpretation and is a measure that shows you instantly if there is a defect, if it is a machine that can be put back into operation or not. If it is a new process or manufacturing machine, it shows you whether or not it meets the standard required in the laboratory for examination.
11. Visual examination of metallic or non-metallic, ferrous or non-ferrous surfaces
Represents the examination on the outside by visual inspection and on the inside by means of a videoscope of metallic or non-metallic, ferrous or non-ferrous surfaces or of joints by welding, riveting or any other fixed, mechanical or removable joint, checking of refining columns, liquefaction, checking special gas and fluid transport installations.
The laboratory analysis will determine if the externally or internally examined surfaces have defects found, consequently it will be known if the equipment or installations can still function in optimal parameters, if they need to be repaired to prolong their life or the need to take repair measures. or replacement of checked sections or containers.
Following the report, great savings are made by preventive testing and timely detection of defects. The best decisions can be made regarding the material, equipment or installation tested for repair, replacement, service life, investment, etc. It is a fast and cheap method.
12. Measuring the hardness of materials
It is a usually mandatory laboratory analysis, which highlights the hardness of the materials in relation to the standard required by the customer and can be done by cross-hardness testing methods (Brinell, Rockwell, Vickers or any other method).
Satisfies the need to know whether the material has an appropriate behavior imposed by the design or by the standard referred to by the customer's request. It is a mandatory measure to be done in the final stages of the works. These hardness tests can be done from ferrous and non-ferrous materials to concrete, asphalt mixtures, glass, diamond or any other material. The need to know if the proposed material meets the minimum mechanical strength required by design or by the customer.
This method eliminates any extra hardness with the hardness analysis before putting the material into operation. It shortens the production time and the continuation of any work that comes after this hardness measurement. It is ensured that the chosen material or composite meets the design rules or standards imposed by the customer.
13. Metallographic analyzes for ferrous and non-ferrous metals, plastics and polyamides
Represents the preparation, performance and interpretation of material composition data, corrosion data, weld data such as measuring the thickness of the weld neck, what kind of polyamide, cast iron analysis, evaluation of spheroidal graphite cast iron, analysis of non-metallic inclusion in steel.
By analyzing and measuring the molecular structure in metals and alloys, in various plastics and polyamides, the beneficiary will know whether or not he can use those materials in the various industries he uses (eg whether the material can be used in the metallurgical, aeronautical, in gas and liquid installations, etc.) and if they comply with various standards.
The analysis brings economic benefits by using materials that comply with the beneficiary's standards or regulations and avoiding or preventing any subsequent defects that could be repaired at costs tens and hundreds of times higher. It is a major saving before the processing of materials in production or series, the fulfillment of the conditions in the regulations for the realization of installations or materials that have been tested in the laboratory. Provides safety in the use of materials by meeting the minimum standard in the applied field.
14. Preparation, inspection and cleaning of pipes
In order to test the pipes aeraulically, to be able to certify that they comply with the required quality standard, tightness tests of the pipes must be made, which previously by cleaning, degreasing, washing, preparation and passivation of the tested pipe surfaces, steps are taken so that they comply. the standard of measurements.
Satisfies the customer's need to measure correctly by pre-cleaning the piping for inspection. Through this analysis we will know if the piping is tight, if it still ensures the tightness or if it also ensures the standard for which it is desired to standardize the respective piping.
The service brings benefits of correct measurement of piping, safety of piping and energy efficiency (no losses, increases energy efficiency).
