Dye Penetrant Inspection

Detect surface-breaking cracks, pores, and welding defects in critical marine components.
Certified, non-destructive testing services for vessels, offshore structures, and shipyards.

What is Dye Penetrant Inspection?

Dye Penetrant Inspection (DPI) — also called Liquid Penetrant Testing (PT) — is a non-destructive testing method used to detect surface-breaking defects on non-porous materials.
In the naval and maritime sector, DPI is especially valuable for identifying cracks, porosity, and leaks in critical components exposed to corrosive and high-stress environments.

The process involves applying a high-penetration dye to the cleaned surface of the component. After a dwell period, excess dye is removed and a developer is applied to draw out the dye from any flaws, making defects clearly visible for evaluation.

Detects Critical Surface Flaws

Identify hairline cracks and corrosion damage on welded joints, propeller blades, rudder systems, anchor mounts, and more.

Ideal for Non-Magnetic Marine Components

Ideal for inspecting aluminum, bronze, and stainless steel components where Magnetic Particle Testing (MPI) is not applicable.

Complies with Marine Industry Standards

All inspections are carried out according to IACS, IMO, SOLAS, and classification society requirements like ABS, DNV, and Lloyd’s Register.

Onboard or Dockside Inspections

Our mobile NDT teams perform inspections at sea, in port, or during drydock, minimizing delays and downtime.

Visible or Fluorescent Dyes Available

Choose from visible red dye or fluorescent penetrants under UV light for enhanced detection on complex surfaces.

Cost-Effective & Non-Invasive

Quick, accurate results without damaging components or interrupting ship operations.
