OEM Internal Pipe Blasting Equipment Factory & Products

Uniformity is maintained through a combination of constant-speed mechanical carriage extraction, stabilized nozzle rotational velocity, and precision-regulated abrasive metering valves. By keeping blast pressure and line speed synchronized via a programmable PLC, the tool deposits kinetic energy uniformly across the 360-degree interior surface.

Internal pipe blasting is an abrasive preparation process designed to eradicate corrosion, mill scale, and contamination while producing an angular surface anchor pattern for optimal coating mechanical adhesion. Internal shot peening, by contrast, utilizes spherical media (cast steel, ceramic, or glass) under strict AMS 2430 / AMS 2432 parameters to induce uniform compressive residual stresses, protecting hollow shafts and tubulars from stress-corrosion cracking and fatigue failure.

Yes. Small and medium tools utilize self-centering adjustable scissor carriages and spring-loaded centering guides that expand or contract to match dimensional changes. For curved geometries and elbows, specialized flexible lances and spherical deflection blast heads are deployed to navigate elbows up to standard bend radii without jamming.

Industrial systems utilize integrated pneumatic vacuum recovery heads attached to the trailing edge of the crawler, or high-capacity downstream negative-pressure suction units connected to the opposite pipe opening. Airflow speeds exceed 25 m/s, drawing exhausted media, dust, and rust particulates directly into an external cyclone separator and cartridge dust collector.

Our tools are built with hardened tungsten carbide or silicon carbide wear liners, allowing seamless operation with steel grit, cast steel shot, aluminum oxide, garnet, glass beads, and ceramic microspheres depending on the specific metal alloy and target cleanliness grade.
