Internal Surface Blasting

Internal Surface Blasting is a specialized process designed to clean, prepare, and finish the internal surfaces of pipes, tanks, vessels, and other cylindrical components. This method ensures the removal of rust, scale, oil, and contaminants that can compromise coating adhesion and performance.

At SAI ASSOCIATES, we utilize specially designed internal blasting tools and high-pressure abrasive systems to achieve uniform surface preparation even in confined or hard-to-reach areas. Our process guarantees excellent coating adherence, corrosion protection, and extended component life.

Key Features

Uniform Internal Cleaning

Ensures consistent blasting and surface finish across internal areas and narrow diameters.

Enhanced Coating Performance

Improves adhesion and corrosion resistance for coatings applied on internal surfaces.

Precision Tools

Uses rotating nozzles and adjustable lance systems for efficient blasting in confined spaces.
