Conventional Non-Destructive Testing (NDT)

Conventional Non-Destructive Testing (NDT) is fundamental to maintaining the safety, quality, and performance of critical industrial assets. By detecting surface and subsurface flaws such as cracks, corrosion, porosity, and wall thinning, these proven methods help prevent unexpected failures and ensure operational continuity.

At CT Precise Engineering Sdn Bhd, we deliver reliable conventional NDT services throughout Malaysia — including Selangor, Johor, Kuala Lumpur, Penang, Terengganu, Kedah, Pahang (Gebeng) and Kemaman. Our certified inspectors perform inspections using methods like UT, MPI, DPI, RT, and more, in full compliance with ASME, ISO, API, and local DOSH standards — ensuring confidence in every result.
