What is the maximum curvature radius the MagTrack Curved Blast Can can clean?

The MagTrack Curved Blast Can is designed to clean curved steel surfaces with a radius of up to three meters “approximately 9.8 feet”. This makes it suitable for moderately curved structures such as small storage tanks and the curved hull sections of ships, where flat-surface tools simply cannot maintain consistent contact or cleaning performance.

Understanding that curvature limit is just the starting point. The sections below answer the most common follow-up questions operators and engineers ask about MagTrack’s surface range, traction mechanics, compatible structures, and when robotic blasting genuinely outperforms manual methods on curved surfaces.

What surfaces and curvature ranges does the MagTrack system support?

The MagTrack system supports flat steel surfaces and curved steel surfaces with a minimum radius of three meters “approximately 9.8 feet”. The standard Blast Can is optimized for flat and near-flat surfaces, while the Curved Blast Can variant extends that range to handle more pronounced curvature, making it a versatile tool across a wide range of steel structures in industrial and maritime environments.

The distinction between the two tool variants is practical rather than theoretical. On a flat deck, hull section, or storage tank wall with gentle curvature, the standard configuration performs reliably. Once the surface begins to curve more sharply, as it does on smaller tanks or at the bow and stern sections of a vessel, the Curved Blast Can takes over. The three-meter radius threshold is the point at which the standard tool starts to lose consistent dome contact with the surface, which compromises both cleaning uniformity and the vacuum seal that keeps water and debris contained.

It is also worth noting that MagTrack is specifically engineered for ferromagnetic steel surfaces. The magnetic wheel system requires a steel substrate to generate the adhesion force that keeps the crawler stable during operation. Non-ferrous surfaces such as aluminum, fiberglass, or concrete fall outside the system’s operating range.

How does the MagTrack navigate curved surfaces without losing traction?

MagTrack maintains traction on curved steel surfaces through a four-wheel magnetic drive system where each wheel carries permanent magnets that continuously attract to the steel substrate beneath. Because the magnetic force acts perpendicular to the wheel surface at all times, the crawler can follow moderate curvature without the adhesion force dropping below the level needed to keep the unit secure and the blast dome properly seated.

The geometry of the four-wheel carrier plays a critical role here. By distributing magnetic contact across four independent wheels rather than a single continuous track or a rigid flat base, the system can flex slightly as it transitions across surface contours. This distributed contact approach means that even when two wheels are on a slightly different plane than the other two, the total holding force remains sufficient to prevent slippage or uncontrolled movement.

For operators working at height or on the outer hull of a vessel, this stability is not just a performance feature but a safety consideration. Maintaining a predictable, controlled movement path reduces the risk of the crawler breaking free unexpectedly, which is particularly relevant when working on surfaces above water or at elevation. Safety bodies including SIR in the Netherlands, EWJI across Europe, WJA in the UK, WJTA in the USA, and DIRV in Germany all emphasize controlled equipment behavior as a core element of safe high-pressure surface preparation operations.

What types of industrial structures are within the MagTrack’s cleaning range?

MagTrack is well suited to a broad range of steel structures found in industrial, maritime, and offshore environments. Its cleaning range covers flat steel decks, large storage tanks, ship hulls, offshore platform legs and columns, and any steel surface where the curvature radius meets the three-meter “approximately 9.8 feet” minimum threshold for the Curved Blast Can variant.

In the maritime sector, ship hulls are among the most common applications. The hull of a typical commercial vessel presents a combination of flat bottom sections and more curved bow, stern, and bilge areas. MagTrack can work across all of these zones, with the tool selection adapting to the local geometry. Small storage tanks, which often have tighter curvature than large industrial tanks, fall within the Curved Blast Can’s range as long as the radius does not drop below three meters.

Offshore structures present a different set of challenges. Platform legs, risers, and jacket structures are cylindrical or near-cylindrical, and their surface condition is critical for corrosion protection. Provided the structural diameter produces a surface radius at or above the minimum threshold, MagTrack can be deployed effectively. In petrochemical and energy facilities, large-diameter pressure vessels and pipework with accessible steel exteriors are also within scope.

Structures that fall outside the range include small-diameter pipes, tight cylindrical columns, and any non-steel substrate. For these, manual or alternative robotic methods remain the appropriate choice.

How does the Curved Blast Can compare to flat-surface blasting attachments?

The key difference between the Curved Blast Can and flat-surface blasting attachments lies in dome geometry. A flat blast dome is rigid and maintains a consistent seal only against surfaces with minimal curvature. The Curved Blast Can uses a dome profile shaped to conform to curved steel, preserving the vacuum seal that keeps water and abrasive debris contained during closed waterblasting operations.

From a practical standpoint, this difference matters most when the cleaning job requires an absolutely clean and dry surface after treatment. Both variants connect to a vacuum unit that collects water and debris without leakage, but the Curved Blast Can achieves this on surfaces where a flat dome would lift at the edges, breaking the seal and allowing contamination to escape. That seal integrity is what makes closed waterblasting viable in environmentally sensitive locations or in areas where surface cleanliness is a strict requirement before coating application.

In terms of operating pressure, both configurations work within the same high-pressure range. The tool selection is driven entirely by surface geometry, not by the pressure or speed requirements of the job. Operators do not need to compromise on cleaning performance when switching between the two variants; they simply match the tool to the surface.

What surface preparation standards can MagTrack cleaning achieve?

MagTrack’s closed waterblasting system is capable of achieving high-grade surface cleanliness standards consistent with international surface preparation specifications. The combination of high-pressure water jetting at pressures up to 3,000 bar “approximately 43,500 PSI” and a vacuum recovery system produces surfaces that meet the requirements for protective coating application in demanding industrial and marine environments.

High-pressure waterblasting at these pressure levels removes mill scale, corrosion, old coatings, and contamination effectively, producing a surface profile that supports strong coating adhesion. The closed-circuit design of the Blast Can system is particularly relevant where environmental regulations or worksite cleanliness requirements prohibit open blasting. By capturing both water and debris at the point of cleaning, the system avoids runoff and airborne contamination, which is a significant advantage in drydock environments, near water, or inside enclosed industrial facilities.

Operators should verify the specific cleanliness grade and surface profile required by their coating system manufacturer and confirm that the MagTrack operating parameters are configured to meet those specifications. Consulting the relevant safety and standards bodies, including SIR, EWJI, WJA, WJTA, and DIRV, is advisable when establishing site-specific surface preparation protocols.

When should operators choose robotic blasting over manual methods on curved surfaces?

Operators should choose robotic blasting over manual methods on curved surfaces when the job involves large surface areas, safety constraints at height or over water, strict environmental controls, or requirements for consistent surface preparation quality across the entire structure. In these scenarios, a robotic crawler delivers measurable advantages in safety, speed, and repeatability that manual methods cannot match.

Manual high-pressure water jetting on curved surfaces such as ship hulls or tank exteriors places operators in physically demanding positions, often at height or over water, while handling equipment operating at pressures between 500 and 3,000 bar “approximately 7,250 to 43,500 PSI”. The physical strain, combined with the inherent risks of high-pressure jetting, increases the likelihood of operator fatigue and human error over extended shifts. Robotic systems remove the operator from the immediate blast zone entirely, which is one of the most direct safety improvements available in surface preparation work.

From a quality standpoint, robotic blasting on curved surfaces produces more consistent results because the tool maintains a fixed standoff distance and traverse speed regardless of operator fatigue or positioning difficulty. On a large ship hull, this consistency translates directly into uniform surface profile and cleanliness, reducing the risk of coating failure caused by underprepared patches.

Manual methods remain appropriate for confined areas, tight geometries below the minimum radius threshold, or small spot-repair jobs where setting up a robotic system would take longer than the task itself. The decision is ultimately a balance between setup time, surface area, safety requirements, and the cleanliness grade required by the project specification.

How MagTrack helps with curved surface blasting

For maintenance engineers and field technicians working on curved steel structures, MagTrack addresses the core challenges of this type of work directly and practically:

• Curvature coverage: The Curved Blast Can handles surfaces with a radius down to three meters “approximately 9.8 feet”, covering small storage tanks and ship hull sections that standard flat-surface tools cannot clean effectively.
• Closed-circuit cleaning: The vacuum dome system collects water and debris at the point of impact, keeping the worksite clean and meeting environmental requirements without additional containment setup.
• High-pressure performance: Operating at up to 3,000 bar “approximately 43,500 PSI”, MagTrack delivers the cleaning intensity needed to meet professional surface preparation standards for protective coating application.
• Operator safety: By removing personnel from the blast zone, MagTrack reduces exposure to the risks associated with manual high-pressure jetting, supporting compliance with guidelines from SIR, EWJI, WJA, WJTA, and DIRV.
• Modular flexibility: The universal carrier platform means the system can be reconfigured for different surfaces and applications without replacing the entire unit, protecting your equipment investment across multiple project types.
