PIPE SPECIFICATIONS AND PIPING LINE CLASSES

The purpose of a pipe specification is to provide standards for pipe, fittings, flanges, Valves, etc. suitable in conveying gas, water, oil and other liquids and products. In the oil, gas, chemical and other industries, the therm "pipe spec" is the common name.
Pipe spec's are technical standards and formal documents, where uniform engineering or technical criteria, methods, processes and practices are described. In petro and chemical industries, hundreds of pipe spec's are used, each for a specific product and or process.

A pipe specification includes many different documents. There are spec's for the various piping materials (Carbon Steel, Stainless Steel and the many other exotics), the various pressure and temperature classes, etc.. Therefore a pipe spec is divided into so-called Piping Line Class (PLC) documents. A PLC document tells you exactly which materials for a pipe system must to be used.

For example: a line must be partially replaced, and you want to order new material.
The PLC document explains that you need to use Carbon steel pipe with a wall thickness XS to NPS 1.1/2, and above with a wall thickness STD. Usually this also applies to the butt weld fittings. Furthermore, the doc tells you the pressure rating of the flanges, which gasket must be placed and which bolts must be used. In the doc are also links to other standards, such as testing, welding, inspection, painting and so on. You will also find a so-called Branch Table, which tells you how a branch is to be made.

PART 1 GENERAL

1.1 SCOPE

A. This specification covers carbon steel piping for general non-corrosive gas and liquid process service.

B. Design limits based on ASME B16.42 Class 150 ductile iron Valves & on EWP's temperature limit on PTFE in gaskets.

C. Corrosion Allowance: 0.0625 inch.

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.
