Ultrasonic Testing

• High frequency Ultrasonic Sound waves detects the flaws in the materials.
• Ultrasonic Testing identifies the presence of discontinuities, material or coating thickness. The detection and location of discontinuities can be determined by the interpretation of ultrasonic wave reflections.
• Ultrasonic Testing method is also used for thickness measurement of materials.
• This is the most common method used in mechanical equipment of industrial installations for the characterization of erosion and deterioration is the thickness measurement.
• SQS offers high level thickness measurement services on pipes, pressure vessels, boilers, tanks, etc by our experienced and certified inspectors.
• Equipments
• Ultrasonic Flaw Detector
• Detection Range : Upto 12,000mm
• Wave types : Longitudinal and Shear waves
• Method : DAC, DGS, AWS
• Ultrasonic Thickness Measurement:
• Detection Range : Upto 200mm
• Wave type : Longitudinal Wave

Magnetic Particle Testing

• An NDT method used for finding the defects or discontinuities on and near the surface in ferromagnetic material. It is a versatile inspection method used for filed and shop applications.
• Magnetic Particle testing works by magnetizing a ferromagnetic specimen using a magnet or special magnetizing equipment.
• If the specimen has discontinuity, the magnetic field flowing through the specimen is interrupted and leakage filed occurs.
• There are three types of MPI named as Dry, Wet and Florescent
• Equipments:
• Magnetic Particle Yoke:
• Magnetic Particle Prod

Liquid Penetrant Testing

• The Penetrant testing works on the principle of capillary action, or the phenomenon of a liquid rising or climbing when confined to small opening due to the surface wetting properties of the liquid, penetrant testing is used for finding surface breaking discontinuities on relatively smooth, nonporous surfaces.
• Solvent Removable Method (Both Visible and Florescent methods)

Positive Material Identification

• An additional remarkable ability of SQS is to provide material traceability of components.
• This method is used for the purpose of analysis of chemical composition in the ferrous materials.

Visual Testing (Borescope)

• Visual Testing is done with the help of advance technology Video Borescope equipment which provides the high quality image and videos.
• The inspection can be done up to 6 meters using the probe also the probe can be inserted in any machine, pipes, tubes, etc.
• Xl Go+ Video Borescope equipment with 6 meter probe.
• Olympus IPLEX-RX Videoscope Equipment with 5 meter probe

Digital Radiography

• An advance method of Radiography Testing.
• This method involved Digital imaging plates in the place of Industrial Radiographic Films.
• The image plate can provide high quality image and the image can be stored in the digital form (CD, Hard disk, Pendrive).
• And also interpretation and evaluation can be done in the system itself.

Film Digitizer

• Film Digitization is a technique used to convert the films into digital medium.
• The films are scanned and stored in the system.
• It is very useful for easy storage and future reference.
• Most of the companies prefer to digitize and store their films.

Laser Sherography

• Laser Shearography is an optical measurement technique for Non-Destructive Testing (NDT) and Quality Control applications, commonly used on composites and metallic materials. The method is used for defect detection in an expedited manner.
• This is mainly applied in aerospace industry, wind power, marine, fabrication, automotive and other composite related industries.

Eddy Current Testing

• Eddy current uses the principle of electromagnetism as the basis for conducting inspections. When alternating current is applied to a conductor a magnetic field develops in and around the conductor. When a second conductor is introduced into the magnetic field and induced current flow is created.
• Eddy current is mainly used for
• Crack Detection and
• Conductivity measurements
• Olympus Multiscan MS5800 Multi scan with ECT, RFT, MFL, and UT channel.

X-Ray Crawler

• X-Ray crawler is an equipment used in pipeline inspection services. The equipment will be inserted into the pipeline to cover a certain distance and inspect. This should be capable of withstand heat, pressure, oil, etc.
• This is mainly used in refining, cross-country pipelines, etc.

• Phased Array Ultrasonic Testing (PAUT) Energy Workforce provides advanced ultrasonic technique.
• Phased Array Ultrasonic Testing (PAUT) used for flaw detection, sizing, and imaging.
• PAUTtechnology is the ability to modify electronically the acoustic probe characteristics.
• Additional advantage of this method is to provide output in image format.

Long Range UT

• Long Range Ultrasonic Testing is a rapid way of screening for corrosion in pipelines. Using this method 100 meter of pipeline can be screened in one test.

Hardness Testing

Testing of various materials from stainless to copper-aluminum alloys (Bronze) using a range of different equipment : Equotip.

Upgradation of Valve Bodies

• The term upgradation refers to the add some make some changes are corrections in the valve bodies.
• If any defect or discontinuities found in the materials, then the same shall be corrected.
• This process involves Gouging, Welding and grinding.
• After successful up-gradation, the material shall undergo stress relieving and after that NDT will be conducted to confirm weather the defect has been rectified.

Heat Treatment:

• Heat Treatment is a process involved to alter the physical and sometimes chemical properties of a materials.
• This method involves the use of heating and chilling, normally to extreme temperatures, to achieve a desired result such as hardening or softening of a material.
• It is of 2 types
• Pre-Heating
• Post Weld Heat Treatment
