Surface treatment almost always involves the use of harmful and aggressive chemicals to obtain surface conditions / preparation. Chemical process lines require bulk additions and regular top ups to ensure process tanks remain within specification. SFE have systems available which limits and avoids the need of operators having to handle chemicals. This is achieved by automating the process by which chemicals are added to process tanks.
With the use of dual containment pipework, we can be confident that harmful chemistry is adequately contained from point of discharge to point of fill. This type of pipe system incorporates socket fusion welding techniques on internal pipework and electrofusion for external pipework.
The pipework systems are fitted with leak detection points along with liquid detection sensors to indicate leaks or compromise in the internal pipework. SFE can incorporate chemical fill and empty systems complete with automatic titration units, interfaced with chemical dosing equipment, within the plant design. State of the art titration analysis equipment regularly check the chemical concentration and depletion levels which calculates the exact volume of chemical additions required. The automatic pumping equipment discharges a precise amount of chemical in accordance to the analysis report, without an operator having to take samples for analysis.
SFE have worked on projects whereby chemicals required for the process line are stored 150 metres away from the plant.
