Liquid Penetrant Inspection

Fracture Identification

Liquid Penetrant Inspection (LPI) is a proven method for detecting surface defects in non-porous materials, including ceramics, plastics, and metals. This technique is highly effective across a wide range of materials, such as metallic and non-metallic, magnetic and non-magnetic, as well as conductive and non-conductive surfaces like stainless steel. LPI offers versatile and reliable performance in identifying surface irregularities, ensuring thorough inspections of various material types.

Advantages

Liquid Penetrant Inspection (LPI) is a cost-effective, highly portable method for detecting surface-level indications and discontinuities. Its key advantage lies in its ability to operate without the need for a power source or bulky equipment, making it ideal for use in locations where other inspection techniques may not be feasible. This flexibility allows LPI to be deployed in a wide range of environments, providing reliable results with minimal setup requirements.

For surface examinations, Magnetic Particle Inspection (MPI) has traditionally been the go-to non-destructive testing (NDE) method. However, when testing non-ferromagnetic materials, alternative methods such as Liquid Penetrant Inspection (LPI) are often selected. Both MPI and LPI offer distinct advantages and limitations depending on the material and specific testing requirements.

At CANEIL, our NDE technicians bring a wealth of experience and numerous certifications, ensuring they have the expertise to select the most appropriate testing method for each scenario. They are equipped to conduct both MPI and LPI, offering informed recommendations based on their findings and the unique needs of each project.
