Products & Services
Radiographic Inspection

Radiographic inspection, also known as radiographic testing (RT), is a non-destructive testing method that uses X-ray or gamma-ray technology to examine the internal structure of a material or object. This type of inspection is commonly used in the aerospace, power generation, oil and gas, and manufacturing industries to evaluate the integrity of equipment and structures.

Our industrial radiography inspection service now includes the use of gamma sources Iridium 192 and Cobalt 60, x-ray, and high energy x-ray (7.5MeV Betatron) A Betatron is a type of high-energy X-ray machine that generates highly penetrating X-rays by accelerating electrons in a circular vacuum chamber. The 7.5 MeV Betatron we use is capable of producing X-rays with energies up to 7.5 million electron volts, which allows us to inspect thicker and denser materials than traditional X-ray sources.

Our team of professionals are qualified with PCN level 2 and SNT-TC-1A qualifications and have demonstrated their knowledge, skills, and experience in the field of industrial radiography inspection. They are committed to providing accurate and reliable results, and to ensuring the safety of themselves and those around them. Our clients can trust that our operators will conduct inspections according to the highest industry standards and provide detailed reports to help them make informed decisions about their equipment and structures.

We have 2 sites which are both accredited to ISO 17025 which allows us to provide a high quality and fast turn-around for all of your radiographic inspection needs.  See our schedule of accreditation or don’t hesitate to contact us for any further information.

Dye Penetrant Inspection

Dye penetrant inspection (DPI), also known as Liquid Penetrant Inspection (LPI) or Fluorescent Penetrant Inspection (FPI), is a non-destructive testing method used to detect surface-breaking defects in a wide range of materials, including metals, plastics, ceramics, and composites. The process involves the application of a liquid dye to the surface of the material, which is then drawn into any defects present, such as cracks, laps, and porosity. The excess dye is then removed, and a developer applied, which causes the dye to be visible and show the location of the defect.

DPI is a relatively simple and inexpensive method of inspection, making it a popular choice for many industries. It is commonly used in the aerospace, automotive, and power generation industries, as well as in the manufacturing of many other products. 

We can offer this service to be conducted on site on in our Kilnhurst facility in Rotherham using either fluorescent or colour contrast applications. 

Magnetic Particle Inspection

Magnetic particle inspection (MPI) is a non-destructive testing method used to detect surface and sub-surface defects in ferromagnetic materials, such as iron and steel. The process involves the application of a magnetic field to the material being inspected, and then the introduction of magnetic particles, typically in the form of a dry powder or a liquid, which are attracted to and congregate around any defects present in the material. The defects are then made visible by the concentrated accumulation of the magnetic particles.

MPI is particularly effective at detecting defects such as cracks, laps, and porosity in ferromagnetic materials, and is also useful for detecting defects in materials that are difficult to inspect using other methods, such as castings, forgings, and welds. The method can be used to inspect both surface and subsurface defects and is effective at detecting defects in both large and small components.

MPI is a relatively simple and inexpensive method of inspection, making it a popular choice for many industries. It is typically performed on-site and does not require any special equipment or facilities. The process is also relatively quick, making it a cost-effective method for inspecting large numbers of components.

FMPI (Fluorescent Magnetic Particle Inspection) is often considered to be more sensitive and more accurate than traditional MPI because the fluorescent particles can be seen more easily under UV light, making it easier to detect even small defects. Additionally, FMPI can be used in low-light or dark environments, making it suitable for inspecting large or complex components where visibility is limited.

However, it should be noted that MPI is not suitable for detecting all types of defects. It is primarily used to detect ferromagnetic defects and is not effective at detecting defects in non-ferromagnetic materials. It is also not effective at detecting defects in materials that have been heat-treated or have a rough surface.

We can offer both traditional MPI and FMPI services on-site or at our Kilnhurst facility in Rotherham.
