Dye/Liquid Penetrant Test

What is Dye/Liquid Penetrant Testing?

Dye Penetrant Testing (DPT), also known as Liquid Penetrant Testing (LPT), is a cost-effective NDT method used to identify surface cracks, porosity, seams, laps, and other discontinuities. It works on the principle of capillary action, where a liquid dye penetrates into surface defects and makes them visible after applying a developer.

Universal NDT Engineering Pvt. Ltd. provides highly reliable and accurate Dye Penetrant Testing (DPT) / Liquid Penetrant Testing (LPT) services for detecting surface-breaking defects in non-porous materials. This non-destructive testing method is widely used across industries to ensure product quality, safety, and compliance with international standards.
