Mechanical (piping) professionals contribute to the delivery of safe, reliable, and code-compliant process facilities by developing high-quality engineering deliverables, including piping system layouts, routing, and tie-ins to process equipment such as reactors, compressors, heat exchangers, pumps, and cryogenic systems. This role requires close coordination with process, mechanical equipment, instrumentation and controls, structural, and civil disciplines to ensure piping designs align with P&IDs, material and corrosion requirements, pressure and temperature extremes, constructability considerations, and interfaces with underground utilities and existing operating units.
