Water jetting (Hydro Blasting) is a non-abrasive surface preparation method where high-pressure water removes rust, scale, old coatings, oil, and salts from steel or concrete surfaces.
- Ensures a dust-free, environment-friendly cleaning method.
- Prevents embedding of abrasives (common in sand/shot blasting).
- Ideal for areas where dust generation is restricted (oil & gas plants, refineries, food industry).
- Provides a clean surface suitable for painting or coating application.
- Common applications: storage tanks, pipelines (internal & external), ship hulls, bridges, power plant structures.
Hydro Blasting Machine Description
A Hydro Blasting Machine is a high-pressure water jetting equipment designed to remove rust, scale, coatings, and industrial deposits using pressurized water.
Key Features:
- Pump: Triplex plunger pump (diesel/electric driven).
- Pressure Range: 4,000 – 20,000 PSI.
- Flow Rate: 10 – 50 LPM (depending on cleaning requirement).
- Operation: Manual gun or automatic system with rotating nozzles.
- Applications:
- Rust & paint removal from steel structures
- Heat exchanger & condenser tube cleaning
- Tank & vessel cleaning
- Pipe descaling & industrial floor cleaning
✅ Advantages of Hydro Blasting over Abrasive Blasting:
- Environment-friendly (no abrasive dust).
- No contamination of surface.
- Can clean in sensitive areas (chemical plants, refineries).
- Safe for stainless steel & special alloys.
