Dye Penetrant Inspection

Dye Penetrant Inspection (DPI) is a NDT method used for detecting surface breaking defects such as cracks, porosity, corrosion, laps and bursts. The big advantage of DPI is that it can be carried out on a wide variety of materials, where as other surface inspection methods are limited to ferritic material only.

Dye Penetrant inspections continue to be an effective and reliable inspection method for components such as; castings, forgings, machined parts and welds.

The two main Dye Penetrant Inspection methods we carry out are;

Colour Contrast Penetrant Inspection - Used for site work. Portable equipment. Very versatile. Good value. Great results.

Fluorescent Penetrant Inspection - Workshop based. Fixed equipment. Very high sensitivity. Great for large components.

All of our experienced inspectors are level 2 certified by the British Institute of Non-Destructive Testing.

Inspection Standard - BS EN ISO 3452-1:2013

Ultrasonic Thickness Measurement

Ultrasonic thickness measurement is a method of NDT used to gauge the thickness of a component or area. This is typically a metallic material, although possible on a variety of materials.

Measuring the Ultrasonic thickness of a component is often useful in a variety of industrial situations. It is necessary for accurate weld evaluation, monitoring of tanks or pressure vessels, observation of ship hulls and examination of steel structures.

Magnetic Particle Inspection

Magnetic Particle Inspection is used to find surface breaking flaws in ferrous (magnetic) materials. Our experienced and qualified engineers can carry out Magnetic Particle Inspection on various components such as: Forgings, Castings, Machined parts and Weldments. This form of Inspection is ideal for both newly fabricated and in-service components.

MPI or MT is often used to certify welds to CE Marking standards and can be carried out on site by our competent technicians.

Inspection Standard - BS EN ISO 9934-1:2016

Visual Inspection

Visual Inspection, or Visual Testing (VT), is the most basic method of inspection. VT requires viewing a component using the naked eye to examine for surface flaws. It requires no equipment except the naked eye of a qualified inspector.

VT can be used for internal and external surface inspection of a variety of components, including forgings, castings, pressure vessels, piping, and weldments.

This inspection is normally used in conjunction with a Magnetic Particle or Liquid Penetrant Inspection, as these are more thorough inspection methods.
VT is simple and much less technologically advanced in comparison to other NDT methods. The advantage to this is that less equipment is needed and costs can be kept down. VT is also one of the most reliable techniques, as a well-trained inspector can detect most signs of damage.
