24、th 6mm green/yellow insulated conductor as per IFC Drawing. Care will be taken while connecting the tube of low pressure side and high pressure side of the equalising/isolation manifolds. All tubing & fitting will be stainless steel and in compliance with project specification & as per IFC drawings.

25、 All vent valves or tubes connected to vent ports will be directed away from the normal personnel access position. Wherever the process connections of instrument are more than one instruments, each will be independently isolated without affecting the function of other instrument process as per IFC d

26、rawing & Project specification. Instrument sunshade will be fitted at proper height, levelled & aligned before fastening to the instrument support in accordance with IFC drawing to ensure that instrument is in centre. Stanchions will be grounded into the nearest grounding bus bar as per the specific

27、ation/instrument grounding philosophy. Name plate tag will install on the instrument. Name plate will phenolic 3 ply (white/black/white). Name plate will contain instrument tag number, instrument type, and service description as per detail drawing. Name plate will permanently mounted to a galvanized

28、 flat bar extension of the instrument stand. Instrument installation will be inspected as per approved ITP. All instruments not allowed to installed on a handrail. All instruments should have a shutoff (root) valve that is readily accessible. Where the root valve is not accessible, pipe or tubing sh

29、ould be added and an additional instrument valve installed at a convenient location.Inline Flange Mounted Transmitters( Note : Inline Flange Mounted transmitter includes Flow meter -Vortex, flow meter - electromagnetic ) The location of Flange mounted transmitter will be determined from P&ID, isomet

30、ric diagram. Ensure that the hydraulic pressure test has to complete from piping discipline prior going for installation. Ensure that the transmitters has calibrated sticker with signature, prior to installation. Flange mounted transmitter will be installed by pipe fitter, instrument fitter will ass

31、ist to Piping crew to technically support. Ensure that the specification of instrument flange & pipe line flange will meet together. If any conflict, Site construction engineer will raise a technical query to design/engineering team to resolve the issue immediately. All the bolts, gasket will be ide

32、ntified from isometric diagram and installation hook up diagram. Flange mounted instrument will be supported by miscellaneous pipe support if required. It will determine from isometric diagram. Flange Mounted transmitters will be grounded into the nearest grounding bus bar as shown in instrument Gro

33、unding. Instrument grounding cable size is 6 mm2 & green colour as per the instrument detail diagram. Name plate tag will install on the instrument. Name plate will phenolic 3 ply (white/black/white). Name plate will contain instrument tag number, instrument type, and service description as detail d
