Magnetic Crawlers, Pipe Robots, and Blast Room Automation
Why Automated Blasting Matters
Automated blasting replaces or augments manual blasting with remotely operated or computer-controlled equipment. It boosts worker safety, accelerates production, and delivers consistent surface preparation across large assets (ship hulls, storage tanks, bridges) and confined spaces (pipes, box girders). Robots maintain optimal standoff, traverse speed, and overlap, improving coating performance and reducing total job cost.
- Up to 2–3× faster coverage on large, flat steel
- Safer work with ground/booth operation, less work at height
- More uniform cleanliness and profile for predictable coating adhesion
- Lower scaffolding, rework, and cleanup costs on suitable projects
Types of Automated Blasting Systems
Crawler Robots (Magnetic/Vacuum)
Crawler robots cling to steel using magnets or vacuum and traverse vertically, horizontally, or overhead. They carry one or more blast nozzles (or UHP heads) and follow programmed paths for uniform passes.
Best for: tank shells, ship hulls, large steel plates, overhead decks
Popular features: dual-nozzle carriages, adjustable standoff, vacuum recovery options
Related gear: remote control pendants, long-reach umbilicals, recovery skids

VertiDrive Magnetic Crawler Robots
Track-Mounted & Gantry Systems
These systems guide a nozzle carriage along rails or gantries, ideal in blast rooms and panel lines. Some use centrifugal wheel technology to throw abrasive and recover it simultaneously for dust controlled operation on floors and decks.
Best for: flat plates, floor decks, repetitive parts in production
Variants: floor wheel-blasters with onboard dust collection; booth gantries with programmable paths

Facility Installed Blasting Robots
Internal Pipe Robots
Pipe robots deliver 360° blasting via rotating heads as the carriage indexes down the pipe. Skids or centering cones adapt to diameter changes.
Best for: pipelines, process piping, heat-exchanger bundles
Capabilities: 6″ ID and up, adjustable rotation speed, push/pull or self-propelled drive

Robotic Arms in Blast Rooms
Articulated arms (similar to automotive robots) repeat complex motions with high accuracy. Programmed paths ensure consistent coverage on batches of identical parts and integrate seamlessly with media recovery and dust control.
Best for: high-volume production parts, repeatable geometries
Benefits: minimal variability, reduced cycle time, traceable programs

Automated Blast Booths & Robotics Integration
Closed-Circuit Automated Blasters
Enclosed blast heads with integral vacuum capture abrasive and debris at the source, great where containment or environmental controls are strict.
Best for: live facilities, lead paint, near waterways, indoor jobs
Benefits: single-pass blast + recovery, reduced cleanup, simplified compliance
Advantages You Can Quantify
Safety & Compliance
Removing the operator from the nozzle minimizes exposure to rebound, dust, noise, and working at height. Robots enable safer work in radiological, asbestos, or lead environments and help meet containment requirements.
Speed & Throughput
Robots maintain ideal nozzle angle, distance, and traverse speed, often achieving 2–3× manual production on large flats and running consistently over long shifts.
Uniform Quality
Consistent overlap and path control reduce misses and variability in surface profile, improving coating adhesion and reducing rework.
Fewer Access Costs
Magnetic crawlers and gantries sharply reduce scaffolding, lifts, and man-basket time.
Labor Efficiency
One trained operator can supervise a robot performing the work of multiple manual nozzles (with support for setup, hoses, and QC).
Practical Considerations & Limits
Up-Front Investment
Robots, power/control packs, and accessories require capital (or rental). ROI arrives through production gains, safety, and reduced access/cleanup.

Setup & Training
Precise setup (path planning, standoff, media flow, air supply) and operator training are critical. Keep a spares kit and establish troubleshooting routines.

Blasting Training & Certification
Geometry & Access
Robots excel on large, regular surfaces. Complex pipe racks and congested steel often still need manual touch-ups.
Power, Air & Media
Ensure adequate compressor capacity, clean/dry air, and appropriate media for the specification. Moisture causes clogs and inconsistent flow.
