PIP PNSM0001 Piping Line Class Designator System

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 This Practice will be revised, reaffirmed, or withdrawn.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 http://www.pip.org.

PIP member companies and subscribers may copy this Practice for their internal use. Changes, overlays, addenda, or modifications of any kind are not permitted within any PIP Practice without the express written authorization of PIP.

Introduction 1.1

Purpose The purpose of this Practice is to provide a uniform system for identifying piping line classes.

1.2

Scope This Practice establishes the system used for identifying piping line classes.

2.

General The base piping line class designator system consists of five alternating alphanumeric fields containing one or two characters each (maximum of eight characters). Each field describes various features of the piping line class. At the user’s option, revisions, alterations, and/or additions can be made to a base line class specification by adding an alphabetic character (maximum of two, making for a maximum of ten characters total to define a line) after the fifth field designator to indicate that changes have been made to the base PIP document. The addendum alphabetic character(s) should be added directly to the base line class designator number as a suffix and without a delimiter. See Section 6 for additional information on revisions, alterations, and/or additions.

3.

Field Definitions and Example 3.1

3.2

3.3

Page 2 of 11

First Field 3.1.1

The first field defines the pressure rating and is numeric in character.

3.1.2

The pressure rating field consists of one or two numeric characters as shown in Table 1.

Second Field 3.2.1

The second field defines the nominal pipe material and is alphabetic in character.

3.2.2

The nominal pipe material field consists of two alphabetic characters as shown in Table 2.

Third Field 3.3.1

The third field defines the corrosion/erosion allowance and is numeric in character.

3.3.2

The corrosion/erosion allowance field consists of one numeric character as shown in Table 3.

3.5

3.6

Fourth Field 3.4.1

The fourth field defines the joint construction/construction type and is alphabetic in character.

3.4.2

The joint construction/construction type field consists of one alphabetic character as shown in Table 4.

Fifth Field 3.5.1

The fifth field defines a sequential number for numbering variations of the line class specification and is numeric in character.

3.5.2

The sequential number field consists of two numeric characters. The field ranges from numbers 01 through 99, with numbers 01 through 79 being reserved for use by PIP and numbers 80 through 99 being reserved for use by owner.

Example An example of a complete piping line class designator is 3CS1S01. This designator means:

4.

First Field:

3

= ASME Pressure Class 300

Second Field:

CS

= Carbon Steel Base Material Piping System

Third Field:

1

= Nominal Corrosion Allowance in multiples of 1/16"

Fourth Field:

S

= Socketweld Small Bore Construction and Buttweld and Flanged Large Bore Construction

Fifth Field:

01

= Sequence Number (first in this piping material/ pressure class series)

Notes PIP Piping utilizes a set of standard notes and note numbers on line class specifications to provide the user with additional information (i.e., guidance, caution, clarification, etc.). Occasionally, a user may find the need to add company- or project-specific notes to a line class specification. This can be accomplished through the use of an Addendum form. Note: Numbers 01 through 699 are reserved for PIP use. Numbers 700 through 999 are reserved for users.

5.

Cover Sheet 5.1

While many users plan to use PIP line class specifications “as is,” some users will find it helpful and/or necessary to attach a “cover sheet” to the document and communicate the extent to which the line class specification applies within the user’s company and/or on the user’s specific project. In cases where no revisions, alterations, or additions are made to the line class specification, the dual-purpose cover sheet/addendum form should be used to convey the user’s application intentions. The cover sheet/addendum form is located in Appendix A.

5.2

6.

TECHNICAL CORRECTION May 2001

When the form is used as a cover sheet, the user must complete the fields for PIP Piping Practice number, piping line class material specification number, and scope. The user should enter the words “No Change” in Sections 2 through 10. The addendum number should not be filled in when the form is used solely as a cover sheet. An example of how the form might be used as a cover sheet is shown in Appendix B.

Revisions, Alterations, and Additions 6.1

Users of PIP line class specifications may have company, location, or project requirements that require revisions, alterations, and/or additions to the base PIP line class specification(s). To accommodate such cases, the dual-purpose cover sheet/addendum form is to be used.

6.1

To use the cover sheet/addendum form for revisions, alterations, and/or additions to the base line class specification, fill in the PIP Piping Practice number, piping line class material specification number, and addendum number alphabetic character(s). Within the applicable section (i.e., Scope, Design, Materials, etc.), fill in the necessary information to detail the deviation(s) being made to the base line class specification. Users may create more than one addendum for a base line class specification. An example of how the cover sheet/addendum form might be utilized as an addendum is shown in Appendix C.
