Non-Destructive Testing
At Macvin Pte Ltd, we specialize in Non-Destructive Testing (NDT) to help industries ensure the safety, reliability, and compliance of their equipment and materials. We hold SAC-SINGLAS accreditation, providing inspection services that support sectors such as construction, oil & gas, aerospace, marine, energy, and manufacturing by detecting hidden flaws before they become costly failures.
Wire Rope Testing Services
(Magnetic Rope Testing - MRT)
Among our NDT capabilities, wire rope testing is critical for ensuring the safe and reliable operation of lifting and hoisting equipment. We provide Magnetic Rope Testing (MRT) services using Magnetic Flux Leakage (MFL) technology to evaluate the condition of steel wire ropes and detect internal and external defects that cannot be identified through visual inspection alone.
Our wire rope testing services help asset owners identify broken wires, corrosion, wear, fatigue, and loss of metallic cross-section at an early stage, reducing the risk of unexpected failures and improving overall equipment safety and reliability.
Why Perform Wire Rope Testing (MRT)?
- Efficient inspection of steel wire ropes without dismantling
- Detection of internal and external wire rope defects
- Reliable inspection even on greased ropes
- Early identification of discard conditions to prevent accidents and downtime
Testing Technique (MRT / MFL)
Magnetic Rope Testing (MRT) is performed using the Magnetic Flux Leakage (MFL) principle, based on TCK.W technology and the magnetic memory characteristics of ferromagnetic materials. Variations in the magnetic field generated within the wire rope allow defects to be detected and localized along the rope length.
This technology provides an effective inspection solution for assessing wire rope integrity by identifying defects that are not visible through conventional visual inspection methods.
Detectable defects include:
- Broken wires
- Corrosion and corrosion pits
- Wear and abrasion
- Fatigue damage
Localized loss of metallic area
Wire rope testing is conducted with reference to internationally recognized standards and accredited procedures, including:
- ASTM E1571 – Standard Guide for Magnetic Flux Leakage Examination of Wire Ropes
- ISO 4309 – Wire Rope Care, Maintenance, Inspection, and Discard Criteria
- Inspections performed under SAC-SINGLAS accredited scope
Applications of Wire Rope Testing
Our wire rope testing services are applied across a wide range of industries and lifting systems, including:
- Cranes (mobile, gantry, tower, and port cranes)
- Automated Storage & Retrieval Systems (ASRS)
- Elevators and lifting systems
- Cableways and cable car systems
- Steel-cord conveyor systems
- Mooring and offshore systems
- Power transmission and mining applications
Related Testing Services
In addition to wire rope testing, we also provide related laboratory and destructive testing services, including load testing and failure analysis of wire ropes, to support comprehensive safety and reliability assessments.
Other Non-Destructive Testing (NDT) Services
Apart from wire rope testing, Macvin Pte Ltd offers a comprehensive range of non-destructive testing (NDT) services to support inspection, integrity assessment, and compliance across various industries.
Our NDT services include:
Industrial Radiography
Radiographic Testing (RT) uses gamma rays to examine the internal structure of materials or components without causing damage. It works by utilizing the property that different materials absorb radiation at different rates, allowing the detection of hidden flaws and discontinuities.
Magnetic Particle Testing
Magnetic Particle Testing (MT), also known as Magnetic Particle Inspection (MPI), is a NDT technique used to find surface and slightly subsurface flaws in ferromagnetic materials such as iron, nickel, cobalt, and their alloys (like steel).
Liquid Penetrant Inspection
Liquid Penetrant Testing (PT) is a widely used, cost-effective NDT method for detecting surface-breaking defects in non-porous materials. The technique relies on the principle of capillary action to draw a highly visible or fluorescent liquid into flaws, making them visible to an inspector. Indications of a wide variety of discontinuity sizes can be found, regardless of the configuration of the test object and regardless of discontinuity orientations.
Ultrasonic Testing (UT - Flaw Detection)
Ultrasonic testing (UT) is a non-destructive method that uses high-frequency sound waves to examine materials for internal flaws, measure thickness, and assess integrity.
Ultrasonic Thickness Measurement (UTG)
Ultrasonic thickness gauging (UTG) is used to inspect the thickness of a material of component. It works by sending high-frequency sound waves into the material with a transducer and measuring the time it takes for the waves to reflect back from the opposite surface. This allows for accurate thickness measurement, corrosion monitoring, and quality control without damaging the part.
Visual Inspection, Remote Visual Inspection with aid of Videoscopes
Visual testing is the observation of a test object, either directly with the eyes or indirectly using optical instruments, by an inspector to evaluate the presence of surface anomalies and the object’s conformance to specification. Instruments such as boroscope, videoscope can be used to facilitate the inspection.
Eddy Current Inspection
Eddy current testing is a non-destructive method using electromagnetism to detect flaws like cracks and corrosion on or near the surface of conductive materials. Its applications include material analysis (conductivity, hardness, coating thickness), and defect detection in industries such as aerospace, automotive, and power generation. It is a versatile, non-contact test that can be used on complex shapes and provides immediate feedback. During in-service inspection paint removal is not required. It can only be used on conductive materials and is best at finding surface or near-surface flaws.
Positive Material Identification
Positive Material Identification (PMI) is used to verify the elemental composition and grade of a metallic alloy. It is crucial for quality control and safety compliance, as it prevents operational failures and hazards that could result from using the wrong material.
PMI is commonly performed on-site using portable devices like X-ray fluorescence (XRF) analyzers, which use X-rays to stimulate a material and then analyze the emitted radiation to determine its elemental makeup, and Spark Optical Emission Spectroscopy (OES), which analyzes the light emitted from a spark created by striking the metal.
Hardness Testing (UCI and Leeb)
UCI (ultrasonic contact impedance) and Leeb hardness tests are portable and NDT methods to measure the hardness of materials. Both methods can be performed on site without removing the parts to be tested.
UCI hardness test uses an oscillating probe to measure the material's hardness by evaluating the Vickers indentation electronically according to the change in its vibration frequency when the probe is pressed into the material.
Leeb hardness test involves using a portable device to launch a small impact body against the test surface, and the material's hardness is measured by calculating the energy loss of the impact body after impacting upon a metal.
Ferrite Testing
Ferrite testing is a non-destructive or destructive evaluation technique used primarily on austenitic and duplex stainless steels to measure the volume percentage or Ferrite Number (FN) of ferrite content. This is critical for ensuring proper mechanical properties, corrosion resistance, and preventing cracking in materials, especially in welds.
