| Routed pipepipe_run | A polyline swept as cylinders, with a slightly oversized sphere at every bend for the elbow. The diameter is the line's PRINTED nominal bore (18/16/14/10/6/4/3/2/1 in) — the one dimension family this P&ID actually gives. 66 runs — headers, meter runs, drains, CI injection |
| Valve bodyvalve_body | Two truncated cones nose-to-nose at the seat (a bowtie), a flange on each side, stem and gland ring on top. The whole body scales from the printed bore. 101 bodies — every MOV, hand valve and control valve |
| Handwheelhandwheel | Red ring (annulus) with four crossed spokes on a short stem — the hand-valve signature, sitting on the valve body. 61 handwheels |
| Actuatoractuator | MOV: drum + square motor box + side gearbox on the stem. Control valve (FC): diaphragm dome + top stem instead. 40 actuators — MOVs, PV-1352, FV-1352 |
| Check valvecheck_valve | Fat barrel + two flanges + a small cone riding on top that points with the flow, so the direction reads from a distance. 9 NRVs |
| Relief valverelief_valve | Angle pattern: inlet flange, body drum, spring bonnet, cap, and a side outlet cylinder. TSVs get a short vent tail pipe. 34 — all TSVs + SRV-1301 |
| Horizontal vesselvessel_horizontal + saddles | Barrel cylinder + two squashed-sphere dished heads; two saddle boxes with base plates carry it to grade. Here it also gets a reducer cone and a dark closure door. 2 — scraper receiver, scraper launcher |
| Filterfilter_vessel + skirt | Vertical barrel + domed top + bolted closure ring just below the dome + drain boss, standing on a cylindrical skirt with a base ring. 4 — receipt filters C/D, basket filters BF-101-C/D |
| Pumppump_baseplate + pump_body + pump_motor | Three parts: two-layer baseplate; volute = casing disc + suction nozzle + discharge riser; TEFC motor = barrel + five fin ribs + terminal box + fan cowl. 4 full sets — boosters BP-102C/D, mainline MLP-101C/D; compact variants for the CI dosing pumps and the vertical sump pump |
| Tanktank | Plain vertical cylinder with a slightly wider top rim. The CI tank adds a cone bottom on legs; the sump tank sits below grade inside a ring. 2 — CI dosing tank 30-TT-O0-102, sump tank 30-TT-00-101 |
| Meter run internalsstrainer / straightener / flow meter | F.S strainer and straightener: a fat sleeve with a flange at each end. Flow meter (FE): barrel + flanges + electronics can on top. 12 strainer sections, 5 meters |
| Instrumentsinstr_stem + gauge / transmitter, ctrl_post + device | Thin stem, then either a dial can with bezel (gauge) or a can with junction box (transmitter). Loop controllers ride a taller post; GD/HD/FD detectors get a sensor head on a 2.3 m post. 33 gauges, 29 transmitters, 14 detectors |
| Specialsinsulating joint / pig signaller | Insulating joint: paired flanges with a dark spacer between them. Pig signaller: a little cylinder with a flag box, on the pipe crown. 2 joints, 5 signallers |
| Sitesleepers / skid_deck / cabinet / boundary_marker | Sleepers: slim T-posts under the long runs. Skid decks: plate + edge skirts. Cabinets: box on a plinth. Off-plot marker: green cone arrow wherever the sheet hands the line to another drawing. 26 off-plot arrows |
