The design temperature, along with the design pressure, fluid characterization and other technical-economical requirements, is a critical parameter in the design and material selection of process equipment, instrumentation and piping. The selection criteria differ slightly depending on the engineering practices, but generally consist of assigning a design margin to the maximum (and minimum) normal operating […]

All pipes are represented in Piping and Instrumentation Diagrams (P&IDs) by lines, with an alphanumeric coding that allows identifying them for subsequent design (routing, thermal stress analysis, supporting, etc.) and purchase.   There are no rules to stablish universal coding; they depend on each project. Although they include basically the same information, the way they are […]
