Designing, creating and maintaining leak-tight fluid systems is critical to the operational efficiency and safety of chemical processing plants. Plant owners and operators must initially consider several variables related to component material compatibility and the right types of fittings to use based on the system’s operating temperatures, pressures, flow requirements and environment, as well as the fluid chemistry. Thereafter, installers need to carefully fabricate, inspect, and test fluid systems to ensure safe, reliable operation. The following tips from Swagelok, a fluid-system products manufacturer, can help plants establish and operate better-performing industrial fluid systems.
