Asset Care
Our Conventional NDT solutions ensure every client receives a safe, reliable, and accurate inspection, and ultimately achieves absolute confidence in their asset’s condition.
Eddy Current testing exposes surface and sub-surface defects whilst leaving surface coatings intact.
Eddy Current testing is an electromagnetic induction technique that used across industries for detecting surface defects in carbon and low alloy steels, and surface, near-surface and sub-surface defects in non-ferritic materials such as brass, copper, aluminium and stainless steel.
The use of induction allows Eddy Currents to be created even if the material has paint coatings in place.
Surface Eddy Current Testing Using handheld probes, Surface Eddy Current testing uses electromagnetic induction to detect discontinuities. Surface testing does not require contact between the probes and metallic parts and in ideal situations, can detect defects as small as 1mm in length.
Defects can be detected through various non-conductive surface coatings, eliminating the need to remove coatings such as paint.
Other advantages include:
Applications for Surface Eddy Current testing include:
Other related services Asset Care has significant expertise executing Surface Eddy Current testing and careful ly interpreting the results. To explore advanced Eddy Current testing techniques, such as Pulsed Eddy Current testing (PEC) and Saturated Low Frequency Eddy Current (SLOFEC), visit Advanced NDT.
Magnetic Particle Inspection, when performed by Asset Care technicians, has the powerful ability to detect discontinuity in ferromagnetic materials.
Magnetic particle inspection is a non-destructive testing technique that pinpoints surface and near-surface discontinuities in ferromagnetic materials. It is the process of examining for features, such as cracks and welds, by using magnetic particles which are drawn to the surface defects by a magnetic field. The inspection process takes advantage of the fact that magnetically susceptible materials are attracted to magnetic fields.
Magnetic particle inspection can be used to detect a number of different types of surface and near surface discontinuities. It can be performed on raw materials, finished or semi-finished materials such as:
Advantages of Magnetic Particle Inspection The advantages to magnetic particle inspection include:
The Asset Care Approach Asset Care’s highly experienced technicians are across these limitations and are trained to identify, avoid and overcome these boundaries if they occur. When magnetic particle inspection is the best non-destructive testing option, our technicians are able to efficiently and accurately execute the testing.
Penetrant testing is a non-destructive testing method used to detect discontinuities open to the testing surface which includes, but is not limited to, cracks, porosity, pipes, seams, forging laps and fusion defects. It is suitable for use on a wide variety of non-absorbent materials such as metals, ceramics and plastics however, porous or overly rough materials are generally unsuitable for penetrant testing.
Penetrant testing is achieved by applying a penetrant liquid to the test specimen’s surface. This liquid is drawn into any surface breaking discontinuity by Capillary Action. After a suitable amount of time, the excess penetrant is removed from the inspection surface and a finely divided developer powder is applied. The developer draws residual penetrant from surface discontinuities thereby providing a visual indication of the discontinuity’s location.
Advantages of penetrant testing Penetrant testing is a highly sensitive, non-destructive method that has incredible capacity for detecting extremely fine flaws and the smallest surface discontinuities. Penetrant testing also has the ability to inspect small objects even if awkwardly shaped, allowing them to be batch tested for improved efficiency.
Discontinuities capable of detection by penetrant testing include:
Industrial Radiography is a common non-destructive technique that uses ionising radiation to reveal flaws in assets and structures which are otherwise not visible. Industrial Radiography is typically used to detect:
Radiography uses a variety of different radioactive sources depending on the requirements of the inspection and the materials being examined. Strict procedures for transportation and handling of the sources are paramount for the safety of operators and the general public.
The Asset Care Approach Asset Care remains an industry leader in the implementation of sophisticated analysis tools and techniques for radiographic imaging and in the use of safe radiation sources. Our capability includes:
Our investment in this area means that our clients can be confident:
Asset Care’s Rope Access Services bring cost-saving advantages and enhanced efficiency to accessing remote locations.
Rope access services is Asset Care’s preferred method for safely and efficiently reaching remote locations. As an alternative to traditional access techniques, such as scaffolding, elevated work platforms (EWPs) and cranes, the time demands of rope access techniques fraction the construction and cost demands of traditional methods without any safety trade-offs.
SRG Global Asset Care is a full operational member of International Rope Access Trade Association (IRATA) and therefore operates to the highest global safety standards and best practices for all rope access tasks.
The SRG Global Asset Care Approach Through combining rope access services with our market leading inspection capability, SRG Global Asset Care can deliver most services using rope access solutions. This includes:
Tube inspections are critical for detecting the common in-service defects of corrosion, erosion, pitting and thinning before they become costly or potentially dangerous threats to asset integrity.
The tube inspection techniques employed by SRG Global Asset Care’s trained experts include:
All the above techniques have application depending on the tube’s material, tube’s dimensions, and the defects that are being specifically monitored for. The defects position, whether internal or external, is another consideration when selecting the inspection method. SRG Global Asset Care subject matter experts can assist you with identifying the appropriate tube inspection method for your application.
Ultrasonic testing is a well-established, highly tailorable technology that uses high frequency sound waves to conduct inspections. Methods range from basic manual testing, through to fully automated testing.
Ultrasonic testing has excellent capabilities for determining:
SRG Global Asset Care’s team of subject matter experts can assist in identifying the best approach for your application.
Visual inspection is a basic inspection method, yet it remains a critical step in inspecting the condition of any asset, from equipment to structures.
Visual inspection can be carried out on an array of assets including equipment and structures, which include:
In the hands of appropriately skilled inspectors, the benefits of visual inspection will reveal important information and a greater understanding of:
The condition of the asset and an assessment, where appropriate, of its functionality and remaining life.
At SRG Global Asset Care, visual inspection is performed by our qualified materials scientists, tank inspectors (API), welding inspectors, and pressure vessel and classified plant inspectors (AICIP and API) and engineers. Our materials scientists, inspectors and engineers are highly experienced and are equipped with effective visual inspection aids, tools and access solutions to ensure the value of all visual inspections are maximised.
