Responsibility of piping engineer regarding Instrument in a process plant includes modelling them in 3D Model at proper locations from where they can be accessed and maintained easily.
Every instruments has its requirements regarding its proper operation. These requirements must be met by the piping engineer while locating them. Piping engineer uses inputs from Process and Instrumentation department along with general layout practices to locate these instruments properly.
1. Process and Instrumentation Diagram from process department.
2. Instrument Hook Up Drawings from Instrumentation Department.
1. PID depicts all instruments required on a pipe line.
2. Piping engineer should model all equipment as per PID.
3. He should assure that all instruments have appropriate accessibility for maintenance, viewing, operation purpose.
1. These drawings provide information about how a particular instrument is to be connected to piping.
2. It also provides information on maintenance requirements, straight flow requirements, access requirements.
3. It demarcates supply scope of piping and instrumentation departments.
Input Provided by Instrumentation Engineering
1. Instrumentation hook-up drawings.
2. Requirements for flow meters.
3. Control Valve Data Sheets / Drawings.
4. Dimensional drawings of various instruments like Level gauges, flow meters, control valves, density meters etc.
5. Instrumentation Ducting drawings / 3d Model.
Output to be Provided to Intrumentation Engineering
1. 3D Model for instruments requirement check.
2. Isometrics for flow meters for minimum straight length check.
3. 3D Model.
Joint Activities to be done with Instrumentation Engineering
1. Clash Checking with instrumentation ducting, other panels etc not modelled by piping department.
