In the competitive field of industrial cleaning and surface preparation, Hydro-Blasting emerges as a superior solution. Known for its efficacy, efficiency, and environmental friendliness, Hydro-Blasting is a key offering in the portfolio of Dynamic Co SA. We have made substantial investments in cutting-edge robotic equipment to ensure our Hydro-Blasting services exceed expectations and meet project timelines.
Understanding Hydro-Blasting
Hydro-Blasting, colloquially known as water blasting, is a technique that deploys a high-pressure water stream to dislodge old paint, accumulated chemicals, or other surface buildups. The principal advantage of this method is its non-invasive nature – it efficiently cleans without inflicting any damage to the base material.
Hydro-Blasting finds wide applications for the cleaning of both internal and external surfaces. Its versatility allows the operator to reach and clean challenging areas that may be less accessible with other cleaning methods.
As a well-established practice for stripping or cleaning, Hydro-Blasting effectively removes materials, coatings, or contaminants from various surfaces such as steel plates, pipes, and machinery. At Dynamic Co SA, we not only have comprehensive expertise in all Hydro-Blasting techniques but also specialize in ultra-high-pressure blasting.
The Hydro-Blasting Procedure
High-pressure and ultra-high-pressure Hydro-Blasting utilize water pressurized between 12,000 to 40,000 psi (800bar–2800Bar). This forceful water stream is directed at the surfaces to remove coatings and debris.
Hydro-Blasting employs two primary methods for removal: erosion and delamination. Erosion is typically used on robust, high-performance coatings such as metal and carbide thermal spray coatings. A specially designed nozzle manipulates the water stream into a concentrated, pencil-like spray. Upon impacting the coating surface, this concentrated stream causes the coating to fragment and erode, leaving the underlying substrate unharmed.
A Hydro-Blasting system comprises of multiple subsystems:
- Pump: This component is responsible for pressurizing the water.
- Nozzle: It controls the delivery of the water stream to the target surface.
- Enclosure: This part contains the process, ensuring safety and efficiency.
- Nozzle and part manipulators: These allow for precise control over the process.
- Waste handling equipment: This manages effective disposal of waste generated from the process.
- Process control devices: These are essential for real-time monitoring and regulation of the process.
As an industry leader, Dynamic Co SA is committed to providing our clients with top-quality, eco-friendly, and efficient Hydro-Blasting services.
Water Pressure Ranges and Definitions for Various Cleaning Techniques
| Definition | Pressure (Bar) | Pressure (psi) | Flow rate (l/min) |
|---|---|---|---|
| Low pressure water cleaning | < 68 | < 1000 | |
| High pressure water cleaning | 68 – 680 | 1000 to 10.000 | 90 – 50 |
| High pressure Hydro-Blasting | 680 – 1700 | 10.000 to 25.000 | 50 – 25 |
| Ultra high pressure Hydro-Blasting | > 1700 | > 25.000 | Down to 12 |
Impact of Water Pressure on Cleaning Effectiveness and Production Rates
| Pressure (bar) | Removal of: | Typical speed (m2/hr) |
|---|---|---|
| Up to 500 | Fouling, salt and dirt. | 300 |
| > 1000 | Also loose rust and paint. Firm adherent paint remains. | 150 (machine) |
| > 2000 | All coatings. Restores original roughness profile. | 5 (handgun) 100 (machine) |
| > 4000 | All coatings. Creates roughness profile. |
Advantages of Hydro-Blasting
Hydro-Blasting is a method that holds a significant edge over other conventional processes used for removing coatings. Typically, coatings removed with ultra high pressure blasting have been applied either by the use of chemicals or by other traditional mechanical means such as grit blasting, mechanical tooling, hammering, scraping, or machining.
Chemical cleaning can be expensive, slow, and environmentally unfriendly. Grit blasting or mechanical tooling, while more cost-effective and faster than chemical processing, often fails to adequately separate the coating and the substrate, which can lead to unnecessary material removal.
Hydro-Blasting offers a range of advantages, including:
- Reduced Waste and Environmental Impact: By using water as the main medium, Hydro-Blasting minimizes the creation of hazardous waste and lowers the environmental footprint. It’s an eco-friendly solution in the realm of industrial cleaning services.
- Preservation of Substrate: Hydro-Blasting allows for the removal of unwanted materials without damaging the substrate. This is particularly beneficial when dealing with sensitive surfaces.
- Versatility: This method can be applied to a broad range of surfaces and can effectively clean intricate or hard-to-reach areas that other methods might fail to reach.
- Cost Efficiency: Hydro-Blasting negates the need for chemicals or abrasive materials, which can be expensive. The process is also time-efficient, leading to decreased downtime and improved productivity.
Ultra High Pressure Water Jetting (UHPWJ
At Dynamic Co SA, we are proud to offer cutting-edge Ultra High Pressure Water Jetting (UHPWJ) services, utilizing state-of-the-art equipment such as Hammelmann’s Dockboy or Dockmate systems. This innovative technology ensures unparalleled quality of work on vessel repairs and maintenance, stripping away coatings, rust, and marine growth efficiently and effectively.
The precision and power of UHPWJ allow for a cleaner, more controlled preparation of surfaces, significantly enhancing the longevity and performance of applied protective coatings.
One of the greatest advantages of opting for UHPWJ services at Dynamic Co SA is the minimal environmental impact this technology offers. Unlike traditional methods, UHPWJ does not produce secondary waste such as grit or chemical pollutants, making it a superior choice for environmentally conscious operations.
For vessels, this means not only a return to service in a shorter timeframe but also an investment in sustainability, preserving marine environments while ensuring compliance with the most stringent environmental regulations.
By choosing Dynamic Co SA for UHPWJ services, our clients benefit from a synergy of quality, efficiency, and ecological responsibility, ensuring their vessels remain in peak condition and regulatory compliance.
