SPE International has rolled out a new series of Vertical Blast Machines, designed for storage tanks, hulls and other vertical steel surfaces.
SPE’s Type 1 machine is used to blast clean vertical surfaces of storage tanks and ships’ hulls, moving from left to right. The remote-controlled system can be operated by one person at ground level, SPE says. A suitable painting system can simultaneously be attached and a camera system included for inspection of the blasted or coated surface.
Type 2 is designed to clean the internal shell of oil storage tanks up to 2 meters from the floor. The blast head is mounted in a framework and the machine driven around the perimeter of the tank during the blast cleaning process. As one pass is completed, the blast head is raised inside the framework and the process repeated—the only system manufactured for this purpose, according to SPE. The unit dismantles to fit in a 600mm access hole in a storage tank.
The series can be used for removal of old coatings, steel preparation to the SA3 standard, and removal of corrosion and mill scale. A magnetic roller clamp secures the unit to the steel structure, and self-propelled variable speed keeps the operator in control of the dust-free operation, the company says.
Unlike conventional methods, the blast head is designed for recovery abrasive of kinetic energy and vacuum.
