Load test and inspection

Load testing and inspection of cranes and lifting gear are essential processes to ensure the safe operation and compliance with regulations. These processes help identify potential defects, weaknesses, or malfunctions in the equipment that could lead to accidents or failures.

Radiography Test

Radiography is the most commonly known non-destructive test method, where used a radioactive isotope (such as ir-192) which called source of radiation.

There are two different radioactive sources available for industrial use; namely the X-ray and Gamma-ray: These radiation sources use higher energy level, i.e. shorter wavelength, versions of the electromagnetic waves. Because of the radioactivity involved in radiography testing, it is of paramount importance to ensure that the Local Rules is strictly adhered during operation.

Ultrasonic Testing

Applications
  • Checking the quality
    of welds in pipe line.

  • Aerospace industries
  • Military defence
  • Offshore and
    Marine industries

Ultrasonic testing is one of the more common non-destructive testing methods performed on materials. This testing utilizes high frequency mechanical energy i.e. sound waves, to conduct examinations and measurements on a test area.
Typically the UT inspection system consists of a transducer, pulser/receiver and display unit. A pulser/receiver is an electronic device that can produce high voltage electrical pulses to the transducer. When driven by the pulser, the transducer generates high frequency ultrasonic sound energy into the material in the form of sound waves.
One of the most useful characteristics of ultrasonic testing is its ability to determine the exact position of a discontinuity in a weld. This testing method requires a high level of operator training and competence and is dependent on the establishment and application of suitable testing procedures. This testing method can be used on ferrous and nonferrous materials, is often suited for testing thicker sections accessible from one side only, and can often detect finer lines or plainer defects which may not be as readily detected by radiographic testing

Phased Array Ultrasonic Testing (PAUT)

Phased Array Ultrasonic Testing (PAUT) is an advanced non-destructive testing (NDT) technique used for inspecting and evaluating the integrity of materials and structures. It utilizes ultrasonic waves to detect defects, measure dimensions, and characterize material properties. PAUT is widely employed in various industries, including aerospace, manufacturing, oil and gas, power generation, and more, to ensure the safety and reliability of critical components.
The main principle behind phased array ultrasonic testing involves the controlled generation and reception of ultrasonic waves using an array of small transducers. These transducers are capable of emitting and receiving ultrasonic waves at specific angles and directions. The ability to control the timing and focusing of each transducer allows for the creation of complex ultrasonic waveforms and beam shapes, enhancing the inspection process significantly.

Magnetic Particle Test

Magnetic Particle Testing (MPT), also known as Magnetic Particle Inspection (MPI), is a non-destructive testing (NDT) method used to detect surface and near-surface defects in ferromagnetic materials. This technique is widely employed in various industries, including manufacturing, aerospace, automotive, construction, and oil and gas, to ensure the integrity and quality of components and structures.
The principle behind MPT is based on the fact that when a magnetic field is applied to a ferromagnetic material (such as iron, nickel, cobalt, or their alloys), magnetic flux lines will flow through the material. When the material contains surface cracks, discontinuities, or other defects, the magnetic field will be distorted around these imperfections. By introducing a magnetic medium, typically iron particles suspended in a liquid (wet method) or as a dry powder, these distortions become visible, allowing inspectors to detect and locate the defects

Hardness Test

Non-destructive testing (NDT) Hardness testing is a technique used to determine the hardness of a material without causing any damage to it. Hardness is the resistance of a material to deformation, and it is an important mechanical property that can provide information about the material’s strength, wear resistance, and suitability for specific applications.
It’s important to note that the choice of hardness testing method depends on various factors such as the type of material, the thickness of the specimen, the required accuracy, and the specific application.
NDT hardness testing is widely used in industries like manufacturing, aerospace, automotive, and construction to ensure the quality and reliability of materials and components without causing any damage to the tested parts.

Engine Spare parts Calibration

Engine spare parts calibration refers to the process of verifying the dimensional accuracy, material properties, and functional characteristics of individual components that make up an engine. Calibration is essential to ensure that the spare parts meet the required specifications and quality standards, allowing them to function correctly and safely within the engine.
Calibration is essential for maintaining engine performance, reliability, and safety. Engine manufacturers, as well as maintenance and repair organizations, follow rigorous calibration procedures to ensure that each spare part meets the strictest quality standards and that engines function optimally throughout their operational life.

Pressure Test

Pressure testing is a common non-destructive testing (NDT) method used to evaluate the integrity and strength of pressure vessels, pipelines, and other components that are expected to withstand internal or external pressure. The primary objective of pressure testing in NDT is to identify any leaks or weaknesses in the tested component that could compromise its safety and functionality.

It’s important to note that pressure testing should always be conducted by qualified personnel who have the necessary training and experience to perform the test safely and accurately. Additionally, the pressure test must comply with relevant industry standards and regulations to ensure the reliability and safety of the tested components, especially in critical applications such as in the oil and gas, petrochemical, and aerospace industries.

Test for Welder Qualification

Welder qualification testing is a critical process used to assess the skills and capabilities of welders before they are employed or assigned to work on specific welding projects. It ensures that welders possess the necessary skills to produce welds of acceptable quality and meet the requirements of the applicable welding codes, standards, and specifications. The specific tests and requirements for welder qualification may vary depending on the industry, project, and governing codes.

The test results and other relevant information are recorded in a welding procedure qualification record (WPQR) or a welding performance qualification (WPQ) document.

Certification: If the welder passes all aspects of the qualification test, they receive a certification indicating their qualification to perform welding tasks within the specific parameters tested.

Post Weld Heat Treatment (PWHT) Test

Post Weld Heat Treatment (PWHT) is a heat treatment process that is performed after welding to improve the properties of welded joints and reduce residual stresses. It involves heating the welded component to a specific temperature and holding it at that temperature for a specified period of time, followed by controlled cooling. The purpose of PWHT is to relieve residual stresses, improve the mechanical properties of the weld, and reduce the likelihood of cracking.

The PWHT process is particularly important for certain materials, welding procedures, and applications where the welded joints are subjected to high stresses or where the service conditions demand enhanced material properties. It is commonly used in industries such as oil and gas, petrochemical, power generation, and aerospace.

It’s important to note that PWHT is not always necessary for all welding applications. It is typically applied when specified by welding codes, materials specifications, or engineering requirements to ensure the safety and reliability of welded components.

Vacuum Test

A vacuum test, also known as a vacuum leak test or vacuum integrity test, is a non-destructive testing method used to check the tightness or integrity of a sealed system or container. This test is often performed to ensure that there are no leaks, cracks, or defects in the system that could compromise its functionality or safety. The test involves creating a vacuum inside the system and then monitoring for any pressure rise, which would indicate the presence of a leak.

Vacuum tests are commonly used in various industries, including aerospace, automotive, electronics, and manufacturing. They are particularly important in applications where maintaining a specific pressure or environment is crucial, such as in vacuum chambers, sealed containers for hazardous materials, or systems involving gases or liquids under vacuum conditions.

Different methods and equipment may be used for vacuum testing, depending on the specific requirements of the system being tested. These methods may range from simple handheld devices for quick checks to more sophisticated setups for precise measurements and analysis.

Liquid Penetrant Test

Liquid Penetrant testing is a commonly used non-destructive testing technique that aids in detecting deformities on the surface of materials. The main subject for such tests is non-porous materials that might have the potential for discontinuities on their surface texture, which may be unacceptable for their intended use.

The Liquid Penetrant Test method provides the location of a variety of surface disparities, some of which are:

  • Cracks caused due to Quenching of metal after Heat Treatment
  • Defects formed during machining processes like milling, grinding, etc.
  • Defects caused due to bending stresses, tensile stresses, etc., may cause fatigue.
  • Fractures are caused due to improper or excess application of load.
  • Voids and defects in weld zones
  • Lap formations in metal

Liquid penetrant testing uses a dye applied on the test material’s surface. This dye enters defect points and cracks and is either visible to the naked eye or fluorescent (which requires special lighting for flaw detection). The penetrant may be sprayed on the surface or brushed, or the workpiece may even be dipped into the penetrant.

The penetrant is then allowed to dwell for a pre-determined time, and the excess penetrant on the surface is removed. Capillary action causes the penetrant to travel deep into the defects. 

A developer is then applied to the surface to bring the penetrant that has seeped into said defects to the surface to create a visual depiction of the deformities’ location, shape, and dimensions.

This visible dye is then observed under white light, specific frequencies, or ultraviolet light and evaluated as per acceptance criteria set by scientific institutions for the particular material and its application.

The Liquid Penetrant Testing technique is preferred because it produces an amplified visible detection of the defect and provides a high-contrast visual that facilitates uncomplicated flaw detection. 

All examinations are conducted in accordance with regulatory code requirements (AWS, ASME, API, ANSI, NAS, MIL STD, etc.) and the customer’s quality assurance standards.
