PIP PNC00002 Abbreviated Piping Terms and Acronyms

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.

Introduction 1.1

Purpose This Practice provides a system for engineers to identify abbreviated piping terms and acronyms used in PIP piping Practices.

1.2

Scope This Practice establishes the definitions and interpretations for all piping-related abbreviations and acronyms used in piping Practices. Abbreviations for technical societies, codes, standards, etc., are not included.

2.

Requirements 2.1

The abbreviations listed in this Practice are uniquely piping-related and shall be used in piping Practices without further definition in those Practices.

2.2

Abbreviations not listed shall be spelled out or defined in a piping Practice in which the abbreviations are used.

2.3

Other interpretations of the abbreviations defined in this Practice shall not be applicable to PIP piping Practices.
