BS EN 9001 ACCREDITED SPECIALISTS IN NON DESTRUCTIVE TESTING (NDT) RADIOGRAHPY / ULTRASONIC TESING / MAGNETIC PARTICLE INSPECTION / DYE PENETRANT ONSPECTION / VISUAL INSPECTION / HARDNESS TESTING / FERRITTE TESTING / THICKNESS TESTING / POSITIVE MATERIAL IDENTIFICATION (PMI & ALLOY VERIFICATION (AV)

We offer a wide range of NDT services so that we can meet all our customer’s requirements, all of which can be carried out either onsite or at our workshop.

X-Radiography & Film Interpretation (RT & RI)

The method of inspecting materials for hidden flaws, by using the ability of short wavelength electromagnetic radiation (high energy photons) to penetrate various materials. We have a large range of x-ray sets ranging from 160kvp up to 300kvp including two panoramic sets all of which are a available for site work. Within our workshop there are three x-ray bays one capable of taking test items up to 33 metres in length. The other taking smaller items such as Pipe Spools, Welder Qualification Tests (WQTs) and Welding Procedure Qualification Records (WPQRs).

Magnetic Particle Inspection

Detects surface and slightly subsurface discontinuities in ferromagnetic materials such as iron, nickel, cobalt, and some of their alloys.

Visual inspection

Is a visual examination by a highly trained staff member viewing materials such as welded joints or fabricated components, castings, forgings, rolled products and several other wrought products to evaluate the product to the required standard.

Ultrasonic Testing (UT)

UT uses high frequency sound energy to evaluate a variety of materials to produce vital information. It’s typically used for flaw detection, dimensional measurements and to determine surface thickness. At Cobalt we are capable of carrying out UT on a range of products including welds, plate, pipe, T joints, nozzles, forgings and wrought products.

Hardness testing

The method of measuring the surface hardness of a broad variety of metals on flat, round, thin or large surfaces using a specific piece of equipment.

Positive metal identification (PMI)

The analysis of a metallic alloy, to establish composition by reading the quantities by percentage of its constituent elements.

Magnetic Particle Inspection

Detects surface and slightly subsurface discontinuities in ferromagnetic materials such as iron, nickel, cobalt, and some of their alloys.

Dye penetrant Inspection

Is a widely applied inspection method used to locate surface-breaking defects in all nonporous materials (metals, plastics, or ceramics).
