PURPOSE AND USE OF PROCESS INDUSTRY PRACTICES
In an effort to minimize the cost of process industry facilities, this Practice has
been prepared from the technical requirements in the existing standards of major
industrial users, contractors, or standards organizations. By harmonizing these
technical requirements into a single set of Practices, administrative, application, and
engineering costs to both the purchaser and the manufacturer should be reduced. While
this Practice is expected to incorporate the majority of requirements of most users,
individual applications may involve requirements that will be appended to and take
precedence over this Practice. Determinations concerning fitness for purpose and
particular matters or application of the Practice to particular project or engineering
situations should not be made solely on information contained in these materials. The
use of trade names from time to time should not be viewed as an expression of
preference but rather recognized as normal usage in the trade. Other brands having the
same specifications are equally correct and may be substituted for those named. All
Practices or guidelines are intended to be consistent with applicable laws and
regulations including OSHA requirements. To the extent these Practices or guidelines
should conflict with OSHA or other applicable laws or regulations, such laws or
regulations must be followed. Consult an appropriate professional before applying or
acting on any material contained in or suggested by the Practice.
This Practice is subject to revision at any time by the responsible Function Team
and will be reviewed every 5 years. This Practice will be revised, reaffirmed, or
withdrawn. Information on whether this Practice has been revised may be found at

NOTES:
01 Where pipe schedule is shown under “SCH/RAT,” it is adequate for the full flange rating. Where “Calc” is shown, the pressure limit may be lower
than flange rating.
02 All buttwelded component thicknesses shall match pipe thicknesses.
03 Threaded joints are permitted only at outlet of vent and drain valves, at hydrostatic connections, at outlet of instrument take-off valves, and to match
equipment.
05 Integrally reinforced branch connections are permitted outside the sizes shown in the branch connection table. Designer shall check weld thickness of
integrally reinforced branch connections to determine if PWHT is required.
06 These valves shall be used only for vent, drain, and instrument connections.
15 To be used when mating to flanged nozzles.
20 Sch XXS pipe and pipe nipples shall be used for threaded connections for sizes NPS 1/2 – 2.
27 Pipe and pipe components thicker than 1/2 inch may require impact tested materials when the minimum design metal temperature is below 100F
(38C) (see ASME B31.3, paragraph 323.2.2).
61 Install in horizontal position with cover up.
62 Install in horizontal position with cover up or in vertical position with upward flow.
