Tracing (commonly referred to as “Heat Tracing”) is one of the most maligned and misunderstood activities the piping designer is asked or required to perform. Many pipers consider it to be “scutwork” and either refuse to do it or grumble as they put forth a less than their best effort.
A valve is a mechanical device that regulates the flow of fluids (either gases, fluidised solids, slurries or liquids) by opening, closing, or partially obstructing various passageways. Valves are used in a myriad of industrial, military, commercial, and residential applications.
