Dye Penetrant Testing (DPT)
Accurate Dye Penetrant Testing (DPT) services for detecting surface-breaking defects in metallic and non-metallic components without causing any damage to the material.
Reliable Surface Defect Detection
Dye Penetrant Testing (DPT), also known as Liquid Penetrant Testing (PT), is a widely accepted non-destructive testing method used to detect surface-breaking discontinuities such as cracks, porosity, seams and laps on non-porous materials.
During the inspection, a specially formulated penetrant liquid is applied to the surface, allowing it to enter even the smallest discontinuities. After removing the excess penetrant, a developer is applied to draw the penetrant back to the surface, making defects clearly visible for inspection.
At Om Metalab, our experienced inspectors perform Dye Penetrant Testing using internationally accepted procedures to deliver accurate, reliable and repeatable inspection results for a wide variety of industrial components.
Dye Penetrant Inspection Techniques
Om Metalab offers multiple penetrant inspection methods depending on the application, material type and required inspection sensitivity.
Visible Dye Penetrant
A coloured penetrant inspected under white light. This economical method is widely used for general industrial inspections and production quality control.
Fluorescent Penetrant
Fluorescent penetrants inspected under ultraviolet light provide higher sensitivity for detecting very fine surface cracks and discontinuities.
Field & Workshop Inspection
Portable inspection equipment allows Dye Penetrant Testing to be carried out both on-site and within manufacturing facilities with minimal downtime.
Multiple Penetrant Systems
We perform water-washable, solvent-removable and post-emulsifiable penetrant testing based on customer requirements and applicable inspection standards.
