No more wasted material with Graco’s XP70
Swire Oilfield Services is a supplier of cargo carrying solutions, modular systems, fluid management and offshore aviation services. The company’s refurbishment facility in Aberdeen, Scotland, provides identification, blasting and painting of assets for re-use offshore. The painting process is a three-coat system comprising an epoxy primer, intermediate coat and polyurethane topcoat. The application of paint is carried out with a Graco Xtreme™ X60 sprayer in a heated paint shop.
The major challenge for Swire Oilfield Services is to reduce the amount of material wasted and the volume of solvent used in the cleaning process and to dilute paint material.
To overcome the problems of paint waste, high solvent use and to meet the mix-ratio demands of the paint materials, the local Graco distributor, NOV Wilson, proposed the use of Graco’s XP70™ and XP50™. Due to the conditions within the paint facility, neither unit required to be heated.
A demonstration was performed using a 4:1 XP70 configured with a suction hose for the primer and a hopper for the material hardener. The unit was also fitted with a mounted Merkur™ flush pump. The application was carried out using the actual paint line and the Graco XTR7™ gun used by the sprayers at Swire Oilfield Services on a daily basis. The inlet pressure was set to the level used during the existing application with Graco Xtreme Sprayers.
During application, the inlet air pressure decreased by 33% compared to the Xtreme–based process. The sprayers liked both the ease of use of the XP70 and the finish. The demonstration ended by pumping the unused virgin material back into the original containers. Paint lines were flushed to show how little solvent is required to clean mixed material in XP70.
Following the demonstration, Swire Oilfield Services noted the improvements that could be made to their process, such as:
- The reduction of wasted paint, solvent use and pump servicing
- Less time spent cleaning pumps
- Less loss of paint line
- Graco XP70’s ease of use
In view of these improvements, Swire Oilfield Services have modified their paint application process to use XP70 units configured to their application requirements. “These machines have proved to be reliable and easy to use. We are using less quantities of paint as less is wasted during paint line cleaning. Also, less solvent is used during the cleaning process. As no manual mixing is necessary resulting in less spillage, the workspace is tidier.” Phil Francis, Operations Manager UK (Central), Swire Oilfield Services.
