Nondestructive testing laboratory

Non-destructive testing (NDT) is a test of the reliability of an object, its individual elements and structures using gentle methods that do not require cardinal disassembly or temporary disabling. NDT includes a study of the physical principles on which the methods and means of control are based, which do not impair serviceability and do not violate the integrity of objects.

Our enterprise carries out the following types of NDT:

1. Visual measurement (optical) –it is the most in demand for control and detection of the smallest damage in transparent products and materials.
2. Ultrasonic (acoustic) – this method is applicable to all materials that freely conduct sound waves in order to solve control and diagnostic problems.
3. Capillary (penetrating substances) — is used to detect leaks and microdamages by filling the internal cavities of the controlled object with an indicator substance.

Each method and instrument is used by NDT to detect the smallest deformations and damage, as well as flaws of various origins, including corrosion, fungus, cracking or delamination. The extreme demand for NDT is explained by advantages of the methods, as well as their compliance with modern industrial safety requirements.

 

Sphere of application

Methods of  non-destructive testing are used today in almost every sphere of economic activity from auto repair shops and shipyards to nuclear reactors and enterprises using HIFs:

1. Vessels operating under excess pressure
2. Pipelines of gas distribution systems
3. Equipment with lifting devices and mechanisms
4. Tanks for storing petroleum products
5. Drilling equipment
6. Chemically and explosion-hazardous production
7. Reinforced stone, reinforced concrete and other types of building structures

 

Various method and tools for NDT are used for:

1. Monitoring the reliability of welded seams and the tightness of vessels operating under high pressure.
2. Determination of the quality of coating with paints and varnishes.
3. Detection of deformations and deviations of important units and parts.
4. Non-destructive testing of equipment with a long service life.
5. Conducting research and identifying defects in various structures for further improving technologies.

 

Tools for NC

Ultrasonic instrument USD-50 IPS

 

The industrial ultrasonic flaw detector USD-50 IPS  is a device for ultrasonic non-destructive testing of material. It is used to search for defects in order to ensure safe operating conditions for equipment of industrial facilities of various directions. The scope of the industry application of the USD-50 IPS flaw detector is indicated by the possibility of using the method of ultrasonic diagnostics in general for analyzing units and assemblies, determining the wear of metal structures (pipelines), checking the integrity of welded joints, searching for defects lying at a depth with determining the coordinates of their location within certain limits, measuring product thickness.

The flaw detector belongs to the class of portable devices for non-destructive testing, it can be used both in a stationary laboratory and during field events.

The flaw detector case is made of impact-resistant ABS plastic (protection class IP65). Among the functional features of the device, we note the following:

 

Hardness tester ТКМ-459

It is a highly accurate ultrasonic device for real-time measurement of the hardness of metals and metal products.

It is designed for non-destructive quality control of products in various industries: metallurgy, machine building, aircraft building, shipbuilding, nuclear, oil and gas and others.

The principle of operation of the hardness tester is the UCI method (Ultrasonic Contact Impedance — ultrasonic contact impedance).

The hardness tester is intended for the operational measurement of the hardness of carbon structural steels in hardness scales (main scales) — Brinell (HB), Rockwell (HRC), Vickers (HV) by the dynamic method (rebound method).

The hardness tester is designed to control the hardness of carbon structural steels according to the Rockwell (HRA), Rockwell (HRB), Shore (HSD) scales — by automatically transferring from the measurement results in the main hardness scales to the corresponding hardness units — according to the tables of the consumer or manufacturer.

The hardness tester is designed to control the ultimate tensile strength (MPa) of structural carbon steels of the pearlite class with the help of  automatically transferring from the results of measurements in the Brinell scale (HB) to the corresponding units — according to the table defined by GOST 22761-77.

The hardness tester is designed to control the hardness of metals and alloys that differ in properties from carbon structural steels. The hardness tester can be used to control hardness:

— heat-resistant, corrosion-resistant, stainless, tool and other steels.

— non-ferrous metals and alloys.

— specialized cast irons.

— hardening and other layers on steel products (carburizing, nitriding, HFC hardening, etc.).

— surfacing and galvanic coatings (chrome, etc.).

— products made of fine-grained materials in the local study of the properties of materials.

In the case when the physical and mechanical properties of the material to be controlled differ from carbon structural steels, measurements are carried out after programming an additional calibration (or an additional scale) using hardness samples from the corresponding material, by the user of the device or at the manufacturing plant at the request of the user.

The hardness tester is intended for use in laboratory, workshop and field conditions.

 

Illumination meter ТКА – PKM (31)

The device is designed to measure the illumination in the visible range of the spectrum (380 ÷ 760) nm, created by various sources, arbitrarily spatially located, in lux.
