Premier Tubular Services International provides high-grade non destructive testing services to Energy sector clients across the globe.
The Tubular NDT (nondestructive testing) is the application of various technologies to detect anomalies such as corrosion and manufacturing defects in metallic tubes. And at the Premier Tubular Inspection Services we provide you with the best professional and independent services.
The NDT Inspection Services
MPI: Magnetic Particle Inspection
Used to detect cracks and discontinuities within ferromagnetic materials (e.g. iron, nickel and cobalt) using a magnetic field and magnetic particles. This inspection technique is also suitably applied to sub-aquatic surfaces such as oil rig structures.
The Premier Tubular Inspection Services Ltd. offers magnetic particle inspections (MPI) – a non-destructive testing (NDT) method for detecting discontinuities in ferrous materials. With state-of-the-art multidirectional MPI test equipment, we can determine a part’s serviceability or conformity to required standards, saving you future costs and delays.
The PTIS personnel are trained and certified in multiple standards and hold a number of certand are capable of analyzing the best NDT method for your product.
DPT: Dye Penetrant Testing
Also known as the Dye Penetrant Inspection, it is a common technique, used to detect surface-breaking defects in non-porous surfaces (e.g. plastic, glass, rubber, metals). The technique employs ‘capillary action’ to draw pigmented liquid to surface defects, allowing for detection.
It is commonly used to detect defects in castings, forgings and weldments. PTIS works with all industry sectors including power generation, petrochemicals and oil & gas, and we can provide dye penetrant inspection on-site at our client’s premises or at our accredited laboratories and technical facilities. In the laboratory, dye penetrant inspection is particularly suitable for the inspection of batch quantities of machined parts, and components
UT: Ultrasonic Testing
PTIS uses ultrasonic testing (UT) to detect surface breakages, dimensional measurement, and material characterization. Ultrasonic waves are propagated through solid material in a controlled manner using multiple functional units such as pulsar / receiver, transducer, and display devices. This is a popular NDT technique due to its flexibility of use.
In industrial applications, ultrasonic testing is widely used on metals, plastics, composites, and ceramics. The only common engineering materials that are not suitable for ultrasonic testing with conventional equipment are wood and paper products. Ultrasonic technology is also widely used in the biomedical field for diagnostic imaging and medical research.
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 dependant 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.
ECT: Eddy Current Testing
This particular method is employed using electromagnetic induction to detect sub-surface flaws in conductive materials. The technique is principally applied to surface and tubing inspections, and secondarily applied to making electrical conductivity and coating thickness measurements.
Over the years, probe technology and data processing have advanced to the point where eddy current testing is recognized as being fast, simple, and accurate. The technology is now widely used in the aerospace, automotive, petrochemical, and power generation industries for the detection of surface or near-surface defects in materials such as aluminum, stainless steel, copper, titanium, brass, Inconel®, and even carbon steel (surface defects only).
VT: Visual Testing
A primary, and time-tested method of NDT, visual testing is applied with or without optical aids. Aids include magnifiers, microscopes, telescopes, and specialized devices such as boroscopes and fiber-optic devices. Experts at PTIS are trained to detect surface flaws and diagnose incongruence using detailed visual inspection.
Visual Testing (VT) is based on the inspection for flaws that are visible to the naked eye and is the most commonly used NDT method across all industries. It allows for a feasible and fast control of quality at every step of the fabrication or maintenance process.
The visual testing allows a number of advantages like reduction in repair costs because of constant monitoring at every step of fabrication, understanding of different degradation phenomena, documentation of the observations using measurement tools, and being the most cost efficient and quick QC/QA technique.
HT: Hardness Testing
Multiple methods are employed to test substance hardness. Relative values from a variety of tests are compared to conclude ‘hardness’. These values are achieved using rebound techniques, ultrasonic contact impedance (UCI), frequency testing of resonating rod with Vickers diamond tip. Hardness testers employed include bench-top Brinell and Rockwell testers. Hardness standards are set as per customer-definitions.
