The magnetic flux penetrates any defects and attracts the particles, highlighting any shortcomings.

What is MPI utilized for detection?

MPI is usually used to detect defects on surfaces, such as toe cracks and crater cracks. It also allows for the identification of areas with porosity. It is a simple, portable method suitable for castings, shafts, and welds. It delivers quick results and can detect imperfections up to 2mm below the surface.

What constraints does MPI face?

This method requires surfaces to be clean before testing begins. It might also require a power source and uses combustible liquids, which could render it unsuitable for certain areas on site. MPI cannot be used on non-ferromagnetic materials.

What exactly is Dye Penetrant Inspection?

Our Dye Penetrant Inspection (DPI) service aims to detect surface-breaking defects by using a dye to highlight cracks, which are then examined under various lighting conditions. This method is quick and cost-effective.

Typically, DPI is used on non-ferromagnetic materials—substances that do not exhibit magnetism and do not contain iron. While our technicians sometimes use this method for ferromagnetic materials, they generally prefer magnetic particle inspection in such cases.

What is DPI utilized for identification?

DPI is frequently employed to assess shafts, castings, welds, and minor machined components. This straightforward and convenient method is effective in detecting surface defects and surface porosity. Additionally, it is used to identify cracks and crater-like breaks.

What restrictions does DPI possess?

This non-invasive testing method can only detect flaws that penetrate the surface and requires a clean surface before inspection. Moreover, it relies on temperature, making it unsuitable for cold environments.

This service is ideal for inspecting storage tanks, pressure vessels, and small metal components. It is also perfect for examining welds, joints in structural steel, and welds under high-pressure conditions. Moreover, it can be effectively employed for inspecting shafts, minor machined components, heat exchangers, and boilers.
