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.

Austin, 3925 West Braker Lane (R4500), Austin, Texas 78759. PIP Member Companies and

Subscribers may copy this Practice for their internal use. Changes or modifications of any kind are not

permitted within any PIP Practice without the express written authorization of PIP. Authorized Users

may attach addenda or overlays to clearly indicate modifications or exceptions to specific sections of

PIP Practices. Authorized Users may provide their clients, suppliers and contractors with copies of the

Practice solely for Authorized Users’ purposes. These purposes include but are not limited to the

procurement process (e.g., as attachments to requests for quotation/ purchase orders or requests for

proposals/contracts) and preparation and issue of design engineering deliverables for use on a specific

project by Authorized User’s client. PIP’s copyright notices must be clearly indicated and

unequivocally incorporated in documents where an Authorized User desires to provide any third party

with copies of the Practice.
