Notes:

  • 02 - Pipe Bending shall be used ONLY where specified on the drawings or where approved in writing by the EWP project engineer.
  • 03 - Specify WN flanges adjacent to welded fittings and/or Butterfly Valves as alternates only.
  • 05 - Threaded joints are permitted only at terminal of vent, drain, and hydrostatic test connections, and at instrument take-off points, and to match equipment.
  • 06 - EWP's TED site preference, class 2000 threaded FS fittings are made only in 45° and 90° elbows, tees, and crosses. The class 2000 fittings are rated same as sch XS/80 (max) threaded pipe. Class 3000 fittings found in existing lines may be replaced by class 2000.
  • 14 - Line blinds, spacers, restricting orifices, and spectacle blinds shall be per Standard Details Doc. No...01 thru 04.
  • 18 - Conical Strainer to be used as temporary start-up strainer at pumps.
  • 20 - Thread sealant to be used on all thread joints except if seal welding is used. Refer to Specification Doc. No....
  • 22 - These Valves have no flanges but are installed between line flanges with extra length bolts.
  • 23 - Cast Valves used in "critical service" or "very critical" service should be considered for radiographic inspection.
  • 24 - BW gate or globe is for alternate use.
  • 25 - Reducing fittings that have ends of different thickness must show thickness (e.g., Conc. Red - SCH XS x SCH STD).
  • 31 - Butterfly Valves NPS 6 & smaller w/ handle; NPS 8 & larger w/ gear operator. Do not use above 177°C service.
  • 32 - Intended for orifice taps only.
  • 33 - Doc. No... for slurry service.

  • 34 - Valves with PTFE may be chosen for use in the OXO reactor loop piping.
  • 35 - Valve Index 180 is alternate for 180K.
  • 36 - May be used for Relief Valve changeover.
