Taking error out of the mix
Once the steel surface of a pipe ending is prepared and the welding is complete (Fig. 1) the pipe is ready to be coated. The coating itself is a two-component liquid anticorrosive, providing the most robust protection for your operations. Though this coating has traditionally been mixed manually, manual mixing can create disappointing results. As in any manual process, human error is inevitable, and preparing the wrong ratios or insufficient mixing can drastically affect the functionality of a coating. That is why Sulzer’s two-cartridge system provides the perfect solution (Fig. 2).
An application for precise and steady flow
Another challenge presented by manual application is the use of rollers and brushes to coat the pipelines. This leaves potential for exposed areas and incomplete protection which can only lead to increased maintenance in the future. Some choose to eliminate this possibility with the use of a multi-component high-pressure spraying device. However, such a device brings more challenges to overcome. Overspraying leads to a waste of coating material, not to mention the damaging impact such a liquid can have on the surrounding environment. The pressure exerted leaves a labour-intensive clean-up operation in its wake.
Overspraying pipe ends leads to a waste of coating material and can drip into the surrounding environment. Our dual-cartridge system uses the precise amount.
A process your teams can work with
Exposure to hazardous materials during manual mixing and the strain of high-pressured spraying devices leave us in need of a new, more user-friendly process. At Sulzer we have designed a solution that eliminates both of these dangers. Unlike bulky high-pressure devices or a wide array of materials, our dispenser is easy to use and requires minimal training. Cartridges can be resealed so remaining coating can be used again for future applications, minimizing waste. We know that welding in the field leaves your unprotected pipe endings exposed to dirt, wind, and rain. Our application can be used irrespective of conditions and gets the job done quickly.
Such outstanding flexibility and reliable performance makes our cartridge-based system an exciting new solution for coating your weld field joints.
