Chemical Analysis of Metal Mechanical Testing of Metal Tensile properties (ASTM E8) provide useful information about the strength and ductility of a metal. Hardness testing is also useful as it can often be correlated with tensile strength and can be done on smaller samples. There are many hardness scales to choose from depending on sample size, uniformity, and industry practice. Brinell Hardness (ASTM E10) uses the largest sample but is useful for materials which are non-uniform such as cast iron. Rockwell Hardness (ASTM E18) has a range of scales covering a large hardness range
and uses less material than Brinell Hardness (ASTM E10). Knoop Microhardness and Vickers Microhardness (ASTM E384)
testing can be used when little sample is available or a specific area is to be measured. Plating hardness (ASTM B578)
and case depth (SAE J423) measurements are examples of microhardness applications.
Our Ultrasonic Thickness Gauge range, is with the best cost/performance ratio. On some of the models the warranties are extended up to 2 years while all of these gauges are efficiently and fully backed up and supported. These models are normally carried in stock for fast delivery.
High penetrating power, which allows the detection of flaws deep in the part.
High sensitivity, permitting the detection of extremely small flaws.
Only one surface need be accessible.
Greater accuracy than other nondestructive methods in determining the depth of internal flaws and the thickness of parts with parallel surfaces.
Some capability of estimating the size, orientation, shape and nature of defects.
Nonhazardous to operations or to nearby personnel and has no effect on equipment and materials in the vicinity.
Capable of portable or highly automated operation.
The global rapid increase in use and demand for energy is a fact. Use of Fossil fuels (coal, oil and gas) is forecast to double by 2030, with most of that growth stemming from developing countires. Alongside this more traditional power source nuclear power, hydro and other renewable engery sources are also set to grow. All of these factors combined bring their own challenges for the NDT industry as a whole as well as individual companies.
Ultrasonic non destructive testing techniques in this area include phased array, manual ultrasonic testing-shear wave and thickness measurement. Application environments within the power generation sector are numerous and include power plants refineries, petrochemical plants, nuclear power stations, wind turbines, transmission towers etc. Most inspections are looking to test for defects in welds, ensuring that they meet applicable operating codes.
Coating Thickness Gages are precision measure instruments that use magnetic and eddy current principles to measure coating thickness on both ferrous and non-ferrous metals. Coating thickness gages measure the thickness of paint plating, coatings and galvanizing on iron steel.
We offer several types of Coating Thickness Gages with the best prices and expedited delivery.
Non Destructive Testing is used across all areas of Marine inspection from metallic based structures through to composite components and structures which include carbon fibre, glass fibre monolithic and cored laminates. There are two key stages to when inspection procedures take place; during manufacture and whilst in-service.
With the changes and challenges in quality assurance and non destructive testing inspection, personnel must be able to acquire the knowledge and skills commensurate with those standards set within the NDT arena. Sonatest supply all the major NDT Schools with equipment and accessories to provide the students and examiners with easy to use, capable, industry standard instruments.
The Sitescan 123 has been designed to enable basic to medium NDT qualification. This unit incorporates features that would be required for thickness/corrosion measurement and welding inspection i.e. DAC.
For the training school the advantage of composite video output can be a useful feature during lectures and classroom deliver.
Quality Assurance plays a crucial role in the fabrication and manufacture of structures. Producers must ensure the delivery of high quality goods to their customers, which often ultimately exist in public environments. Such fabrications are produced to strict specifications and the structural welds used in creating finished goods must be inspected using Non Destructive Testing methods. Weld inspection is a primary NDT application.
Sonatest Flaw Detectors such as the Sitescan range contain a range of software features to assist with interpretation of ultrasonic echoes from welds, as well as evaluation tools such as DAC, AVG/DGS, AWS D1.1, API 5UE to comply with a number of different inspection standards.
Phased array ultrasonic inspection, using the Veo 16:64, this essentially replicates the principle of a standard ultrasonic inspection, but by using electronic rather than physical scanning over the weld volume, achieves a much faster inspection rate.
Dye-Penetrant or MPI is used on many parts, particularly where geometric considerations or thin sections make other techniques difficult. Penetrant is a surface technique: it can only detect defects such as cracking or porosity which are open to the surface.
For basic thickness measurement of components a thickness gauge from T-Gage IV series is ideal. Paint and coating thicknesses can be controlled using a gauge from the Sonacoat range.
