Introduction to Water Blasting Technology
Water blasting, also known as hydroblasting, has revolutionized industrial cleaning and surface preparation. Unlike traditional methods, water blasting uses high-pressure water jets to remove contaminants without damaging the underlying surface. This eco-friendly technique is widely used in industries ranging from marine to construction.

FAQ
What is the difference between water blasting and pressure washing?
Water blasting uses much higher pressure (1400+ bar) than pressure washing (typically under 140 bar), making it suitable for industrial applications rather than residential cleaning.
What are the main safety considerations when using water blasting equipment?
Always wear appropriate PPE, follow manufacturer guidelines, maintain safe operating distances, and ensure proper equipment maintenance to prevent accidents.
Can water blasting damage surfaces?
When properly used, water blasting is designed to remove contaminants without damaging the underlying surface. The key is matching the right pressure to the material being cleaned.
What is the maximum pressure range for water blasting systems?
Ultra high pressure systems can reach up to 60,000 PSI (4,000 bar), though most industrial applications typically use pressures between 2,000-20,000 PSI.
How often should water blasting equipment be maintained?
Regular maintenance, including filter cleaning and inspections, should be performed according to manufacturer guidelines, typically every 50-100 hours of operation.
What industries commonly use water blasting?
Common industries include marine, construction, manufacturing, oil and gas, and power generation, each requiring different pressure ranges and equipment types.
Can water blasting be used for concrete demolition?
Yes, hydrodemolition using ultra high pressure water blasting is an effective method for removing concrete while preserving the underlying rebar structure.
What are the environmental benefits of water blasting?
Water blasting is eco-friendly as it uses water as the primary cleaning agent, eliminating the need for harsh chemicals and reducing environmental impact.
How does flow rate affect water blasting performance?
Higher flow rates are better for removing softer materials, while higher pressures are more effective for hardened deposits. The optimal combination depends on the specific application.
What should I consider when choosing a water blasting system?
Key considerations include the type of material being cleaned, required pressure range, flow rate needs, operating environment, and budget constraints.
