BLASTING SYSTEMS / STEEL SURFACES

Blastrac steel blasting systems are the most effective and environmentally friendly methods for removing paint, coatings, corrosion, non-skid and other contaminants from steel surfaces. Blastrac steel blasting
systems using steel shot and angular steel grit, or a mixture of the two in a variety of sizes allowing the operator to achieve a wide range of anchor profiles and roughness needed for almost any type of coating
application.

HORIZONTAL SYSTEMS

Horizontal steel blasting machines are used to prepare steel surfaces such as storage tank floors, roofs and steel plates, ship decks, hatch covers, tank tops, barges and other marine vessels, bridge decks,
helicopter landing decks, and walkway’s on offshore drilling platforms.

VERTICAL SYSTEMS

Vertical steel blasting machines are used in conjunction with specially developed Blastrac cone, dome and floating roof rigging systems which are constructed on top of the roof and/or floating walkway. They can also be adapted for blasting ship hulls and any other vertical steel surfaces.

WORKING PRINCIPLE

The working principle of all BLASTRAC-EBE equipment is based on the laws of kinetic and mechanical energy. The blasting operation is performed by steel shot and angular abrasive being thrown at high velocity against the surface to be cleaned. Throwing action is achieved through centrifugal force, where a wheel with blades located radially is rotated at very high speed. On to this revolving wheel, abrasive is fed in such a manner that it travels along the radial length of the blades is then is thrown off in a high velocity stream at the surface to be cleaned, efficiently blasting the work surface. After the abrasive has impacted the work surface horizontally, it rebounds back into the machine. Inside the machine the abrasive is separated from the dust and debris. The abrasive is returned back to the abrasive storage hopper to be re-used. The debris is transported by air flow into the dust collector, where it is collected to enable it to be packaged into containers for disposal. This process is an on-going and automatic continuous operation.

RIGGING SYSTEMS FOR THE 900VMB VERTICAL STEEL BLASTER

TO BE ABLE TO DRIVE AROUND STORAGE TANKS

Using the Blastrac 900VMB vertical blasting machine in conjunction with a Blastrac rigging system increases the total performance of the machine, without interfering with other trades working disciplines.
It also helps to reduce total square meter costs compared with compressed air powered blast cleaning or high pressure water blasting, both of which create immense pollution for the local environment.

 

Blastrac has developed a number of specific optional rigging systems to increase the performance of their client’s vertical steel blasting systems, and thus simplifies the operator responsibilities and job scope. The Blastrac vertical steel blasting machine 900VMB is designed to work in an up & down direction over the vertical surface shell of a storage tank and/or offshore oil platform.

 

Blastrac rigging systems have been developed to adapt to a cone or domed roofed tank, as well as the internal or external surfaces of the shell of a floating roofed tank. The integrated endless winch system
of the 900VMB vertical steel blaster allows the operator to control the movements of both the rigging system and the vertical blast cleaning machine from a mobile control station located on the ground. From
there, the operator has the perfect control for blasting travel speed of the system and an overview to execute and control the job he performs.

 

Blastrac rigging systems are made with high grade components and include all the necessary certification. Depending on the type of tank (cone, dome or floating roof) and the type of construction you have on
the top of it (railing, tank guarder, fire extinguishers, water pipes…), we have the rigging system you need, either standard or custom made.

BLASTING OF SHIPS & OFFSHORE PLATFORMS – HORIZONTAL

In the shipping and ship repair yard industries, the Blastrac blasting machines for steel surfaces preparation are designed for processing small and large areas on horizontal and vertical surfaces. Horizontal steel blasting machines are used to clean and profile horizontal surfaces as ship decks, aircraft carrier landing decks, hatch covers and similar horizontal surfaces.

 

Blastrac 350S & 500S horizontal steel blasting machines can either be used in the shipyard during normal maintenance programmes or at sea whilst the ship is travelling between ports. On offshore platforms, helicopter landing decks and access walkways it is possible to blast clean without disrupting the normal day to day working of the platform.

 

Vertical machines are suspended from either a crane or a Blastrac winch system and operate in an up or down direction to clean and profile ship hulls; they are remotely controlled from a mobile work station. Blastrac machines fully comply with the very strict safety operating conditions that exist in the industries.

BLASTING OF SHIPS WITH THE 900VMB STEEL BLASTER

TO CLEAN THE VERTICAL SURFACES OF SHIPS

Ship hulls are other vertical surfaces that need to be blasted. The coating system on a ship hull must be renewed either partially or totally over time because of the prolonged exposure of the ships hull with salt
water gradually resulting in corrosion and fouling. This process of cleaning the surface before coating is called surface preparation. Our 900VMB vertical steel blaster is the perfect machine to carry out this
process when the surface is flat before applying a new coating.

 

Ship hulls are not the only vertical surface that needs to be blasted on a ship. Ship holds have the same issue as ship hulls, and their walls need to be cleaned in order to remove rust, mill scale, oil, corrosion
products, oxides, grease, paint or any kind of other foreign matter, and at the same create a clean profile. In this way, the surface is ready for the application of a new coating without any extra action. The 900VMB
vertical steel blaster can easily achieve an “SSPC-SP10 Near White Blast Cleaning”, that’s why it is the perfect machine for this kind of job.

 

Depending of the characteristics of the ship, it is possible to adapt different rigging system: it could be a mobile crane, a forklift or any equipment that allows you to properly hold the machine. Then the
integrated winch system will be used to operate the machine up & down.

BLASTING OF PETROCHEMICAL SURFACES

In the petrochemical industry Blastrac steel blasting machines are used as a quick and efficient surface preparation method prior to painting small and large surfaces of storage tanks areas, for example, the internal bottom and the external roofs of oil storage tanks. Because of the environment and location of storage tanks in and around oil refining sites, the blasting process must be dust free and safe.

 

The Blastrac 350E Global & 500E Global horizontal steel blasting machines are specially manufactured for the petrochemical industry, the systems are modular and designed to enable each machine to be disassembled and that the parts of the machine can pass through a standard 24” / 600 mm manhole for the 500E unit and even less for the 350E. Most other equipment would not fit through a standard 24” / 600mm manhole. All the E Series of equipment are built according to the strictest safety devices that allow blasting safely in storage tank areas.

The Blastrac 900VMB vertical blasting machine for steel surfaces is designed for processing large areas on vertical surfaces. The machines are suspended from a crane and or a Blastrac cone, dome or floating roof rigging system and operate in an up or down direction to clean and profile steel shells of tanks. The unit is remotely controlled from a mobile remotely panel.

BLASTING OF PLATFORM WITH THE 350EX STEEL BLASTER

EQUIPPED WITH SPECIAL SAFETY DEVICES

The 350EX horizontal steel blasting machine is equipped with special electrical safety devices, so the machine can be used for storage tank and oil platform blasting. The Blastrac 350EX, as well as the
BDC-655EX dust collector, is equipped with explosion proof electrical panels (IP66/67) / (EXD II 2G d II B T4) & explosion proof electrical motors.

 

The Blastrac 350EX can be used on offshore platforms to blast clean helicopter landing decks and access walkways without disrupting the normal day to day working of the platform. In the petrochemical
industry, the Blastrac 350EX is used as a quick and efficient surface preparation method prior to painting small and large surfaces of storage tanks areas, for example, the internal bottom and the external roofs
of oil storage tanks. Because of the environment and location of storage tanks in and around oil refining sites, the blasting process must be dust free and safe.

 

The Blastrac 350EX is specially manufactured for the petrochemical industry because of its explosion proof properties.

 

Like the 350E & 500E steel blasting machine, the 350EX is specially designed to enable the machine to be disassembled and that the parts of the machine passes through a manhole access less than 600 mm
opening into areas inside tanks that are normally inaccessible to blasting machines.

MAINTENANCE OF WIND TURBINE TOWERS WITH THE 200VMB STEEL BLASTER

TO MAINTAIN OFFSHORE TOWERS

Throughout the years, it is not uncommon for wind turbine towers to show signs of damage from corrosion. If this affects the flange connections or the reinforcement, this may endanger the operation and static stability of the wind turbine. That’s why it is necessary to eliminate this corrosion.

 

Our 200VMB vertical steel blaster is the perfect machine to carry out the surface treatment of wind turbine towers. In only one pass, it will eliminate the corrosion and will leave the surface thoroughly cleaned with an anchor profile which ensures proper adhesion of the coating system to the steel. This process eliminates access requirements such as scaffolding and allows you to carry out safe, clean, efficient & environmentally friendly operations. Depending on the wind turbine design a rigging or lifting device needs to be adapted to the 200VMB.

BLASTING OF WIND TURBINE MONOPILES WITH THE 900VMB STEEL BLASTER

TO CLEAN & CREATE TEXTURE ON MONOPILES BEFORE APPLYING A NEW COATING

Our 900VMB vertical steel blaster, in combination with the 900DC Blastrac dust collection system, can also be used to blast the monopiles of wind turbines. The objective is to both clean & create texture on
the external part of the monopiles before carrying out the metalisation process or before applying a new coating. Because windmills may be subject to difficult weather conditions (wind, salt, rain, heat, UV…), the
surface preparation of the monopile is a key element for a long lasting coating.

 

With the 900VMB Blastrac vertical steel blasting machine, we are able to generate an optimal, clean profile SA 2,5 according to the ISO norm 8501-1. The created anchor pattern will ensure proper bonding of
the coating to the work surface. The anchor pattern is basically the peaks and valleys on the surface of the metal on a microscopic scale. It particularly depends on the abrasive you use: round steel shot and or
angular steel grit.

 

The machine works on a stationary vertical position and moves only from right to left or left to right. The monopile turns around itself in order to expose the surface in the front of the 900VMB mouth.

 

It is a highly effective option over manual open-blasting. Our 900VMB vertical steel blaster works in closed circuit, so there is no dust released in the environment. In addition, the abrasive is recycled which
makes the steel blasting process really time & cost effective.

 

Blastrac didn’t develop a specific rigging system for this application. It is up to the customer to select the best option depending on its facility, diameter & length of the pipes… of course we can help you to find the best solution.
