Refractory Materials Testing

Engineering Materials capable of withstanding high temperature such as furnace lining are generally classified as the refractory materials. They are most commonly inorganic in nature. Their general composition is mixture of stable minerals, different additives and binder phase. These materials are in general having excellent resistance to abrasion and abrasion even at very high temperatures. These materials have tendency to withstand high temperature in furnaces and high temperature applications. Refractory materials are comprises of oxides, nitrides, and carbides of metals and non-metals.

X-ray Digital Radiography

PMT Lab has expanded its testing capabilities to cater for the need of our industries and offers two methods of X-ray inspection to meet requirements of standard specifications and customer’s preferences:

a. Computed Radiography / Digital Radiography (CR)

b. Conventional Radiography / Film Radiography (XR)

Conventional radiography utilizes film which is able to produce a high-contrast image that is viewed on a film reader. Computed or digital radiography has the ability to adjust contrast and zoom into areas of greater interest and produces a digital image that can be saved to a disc, emailed to customers and easily archived.

Sample Requirements:

✔ Any shape of the sample can be inspected.

✔ Sample should be maximum of 600 x 900 mm.

✔ Sample should maximum of 100 Kg.

Facilities:

✔ Both types of industrial radiography (digital & Film) are performed on solid materials.

✔ The digital and film images are evaluated by Qualified Engineers according to the required test specifications.

✔ Industrial radiography is performed as per MIL and ASTM specifications.

Capabilities:

Digital radiography and conventional radiography both provide information to determine the soundness of a material or product and are valuable inspection method for a variety of purposes

1. Detect internal discontinuities such as shrinkage, cracking and porosity

2. Verify the integrity of internal components

3. Determine the quality of welds

4. Identify the extent of corrosion

Standard Test Methods:

✔ ASTM E94

✔ ASTM E1000

Ultrasonic Testing

The ultrasonic principle is based on the fact that solid materials are good conductor of sound waves. Whereby the waves are not only reflected at the interfaces but also by internal flaws (material separations, inclusions up to depth of 5 meters. The interaction effect of sound waves with the material is stronger the smaller the wave length, this means the higher the frequency of the wave.

Dye Penetrant Testing

Liquid penetrant examination is one of the most popular Nondestructive Examination (NDE) methods in the industry. It is economical, versatile, and requires minimal training when compared to another NDE method. Liquid Penetrant exams checks for material flaws open to the surface by flowing very thin liquid into the flaw and then drawing the liquid out with a chalk-like developer. Welds are the most common item inspected, but plate, bras, pipes, castings and forgings are also commonly inspected using liquid penetrant examination.

Magnetic-Particle Testing Technique

Magnetic-Particle examination (MT) is a very popular, low-cost method to perform nondestructive examination (NDE) of ferromagnetic material. Ferromagnetic material is defined in ASME Section V as “a term applied to material that can be magnetized or strongly attracted by a magnetic field.” MT is an NDE method that’s checks for surface discontinuities but can also reveal discontinuities slightly below the surface.

Industrial Fiberscope

Another type of borescope is a fiberscope. It uses fiber optic stands to project the image from the tip of the probe to the eyepiece and view the internal surface of bores, tubes and pipes up to length of 2750mm. its advantage is its flexibility. It is able to bend into areas that may be impossible to get to with a rigid scope. The head of the probe ids also able to be maneuvered once in place, say with in a compressor turbine area, in order to gat different fields of view.

Quality Control Bridge

The scope of Quality Control Bridge is to sorting of Ferromagnetic materials by comparing their magnetic hysteresis loops in the form of rods/bars.

Quantitative Analysis by Atomic Emission Spectroscopy:

The test specimen is prepared by grinding the sample material to obtain a uniform, clean and flat surface free of contamination. Atomic Emission Spectroscopy systems have a spark source that creates the energetic environment. The atoms in the sample are energized using a rapid series of high energy sparks in an argon-filled gap between an electrode (cathode) and the surface of the specimen. Element analysis by Atomic Emission Spectroscopy entails comparing the emission lines from the sample to known standards to identify the element and calculate the quantity of the element. Consequently, the elemental composition can be determined both qualitatively and quantitatively by the types and intensities of the emission lines.
