A Typical Process Plant or Oil & Gas ProjectA typical process plant or oil and gas project comprise of many stages from concept to commissioning and production plant. A work flow diagram of an EPC project is shown.Click here Detail Engineering Phase : PipingStudyDuring detail engineering phase various engineering departments contribute to the study and design of the plant such as civil,mechanical,electrical,instrumentation,architecture,process and piping.
Piping forms the backbone of the detail engineering phase.
