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.
