NDT Method
What is Dye Penetrant Testing?
Dye Penetrant Testing detects surface-breaking defects on any non-porous material using a penetrating dye and developer.
Overview
Dye Penetrant Testing (PT) applies a dye that seeps into surface-breaking defects. After removing the excess, a developer draws the dye out to reveal the flaw. Unlike MPI, PT works on non-magnetic materials such as aluminium and stainless steel.
It is a highly sensitive, low-cost method for finding surface cracks, porosity and leaks.
What PT Detects
- Surface cracks on any non-porous material
- Porosity and leak paths
- Defects on aluminium and stainless steel
- Fine surface discontinuities
