Services for Steel Petrochemical / Storage Tanks

Over time, exposure to the environment and stored media can result in the reduced efficiency & performance of storage tanks.

This is especially so in the petrochemical industry where for example the build up of corrosion & oil residue on internal walls may reduce the efficiency of seals on floating roofs and environmental damage to exterior surface coatings may lead to problems with structural integrity.

SPE Contracting Ltd. are one of the only companies operating on a world-wide basis offering a complete service in the removal of old coatings & deposits from storage tanks – both internally and externally. Further, the state-of-the-art equipment captive shot blasting equipment at our disposal allows us to offer a dust free & environmentally friendly solution.

Storage Tank Walls - Vertical Shot Blasting

In depth knowledge of the the type of material and task processes are essential in formulating an optimal, efficient & cost effective surface preparation solution, and with SPE Contracting, this is assured.

The V3 Series remote controlled vertical shot blasting machine is designed for the blasting of large vertical / near vertical surfaces (both external & internal).

Suspended via a rigging system or crane, the V3-16 operates in an up/down motion; ideal for the profiling of steel tanks.

A working width of 406mm combined with fast blast rates ensure a quick & efficient process delivering the finish required to SA2.5 (if required, profiles of up to SA3 can be achieved). Abrasive loss and dust emissions are kept to a minimum by specially designed magnets attached to the machine that pull it toward the steel work, whilst a powerful vacuum system collects the debris for easy disposal.

The SPE V2-12 Vertical Shot Blasting machine is used to blast clean the internal shell of oil storage tanks from the floor up to 2m in height. The blast head is mounted in a mobile framework and the SPE V2 is 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.

In the field of operation, the SPE V2 is extremely efficient blasting at a rate of 25 – 30m squared per hour up to an SA2.5 standard. Whilst electrically & mechanically complying with the general safety requirements of the petrochemical industry, the SPE V2 can easily be adjusted to suit any site specific regulation.

This is the only radial shot blasting system manufactured worldwide specifically for this purpose.

Preparation of Storage Tank Floors

SPE Contracting carry a vast range of horizontal walk behind shot blast machines with blasting widths from 9″ to 20″ with different powered options that allow us to blast clean internal tank floors in a manner that suits a clients particular safety requirements.

All are designed to operate with both cost effectiveness and efficiency in a captive blasting process, collecting dust and debris for easy disposal making for a highly reliable environmentally friendly solution. They can also be dismantled to pass through a 600mm access hole.

Mill scale, rust and surface contaminants can be removed with ease at fast blast rates to leave a cleaned surface to SA2.5 standard (although the machines themselves are capable of blasting to SA3 standard).

Storage Tank Roofs and Ceilings

The exterior roof surface of a storage tank is directly exposed to the outside elements. Even with coned roofs, the exterior needs to be cleaned to remove surface deposits and contaminants prior to a new protective coating being applied.

Whether you have coned roofs or floating ceilings, we have both the skill and technology to ensure a thorough cleaning process.
