FOREWORD

In 2011, The American Society of Mechanical Engineers (ASME) established the Committee on Nonmetallic Pressure Piping Systems (NPPS) to develop standards for the construction of nonmetallic pressure piping systems. This Commit- tee’s goal was to specify construction1 requirements for nonmetallic piping and piping products; such requirements were not adequately defined in existing standards.

Prior to the development of the ASME Standards for Nonmetallic Pressure Piping Systems, nonmetallic pressure piping requirements were contained within several existing standards. The nonmetallic piping requirements of the ASME B31 Code for Pressure Piping varied across Sections, with some Sections having no requirements for nonmetallic components at all. Other standards and codes, such as ASME RTP-1 and the ASME Boiler and Pressure Vessel Code (BPVC), Section X, included requirements for reinforced thermoset plastic (RTP) corrosion-resistant equipment but not for piping and piping components. ASME BPVC, Section III did have a few Code Cases that addressed requirements for some nonmetallic piping and piping components, including those made from glass-fiber-reinforced thermosetting resin (FRP) and a few thermoplastics, e.g., high density polyethylene (HDPE) and poly(vinyl chloride) (PVC). However, the scope of these Code Cases was very limited, and in some cases the methodology was nearly 30 years old. The ASME NPPS Standards now serve as a centralized location for NPPS requirements and are developed by committees whose members are experts in this field. The NPPS Committee’s functions are to establish requirements related to pressure integrity for the construction of nonmetallic pressure piping systems, and to interpret these requirements when questions arise regarding their intent. ASME and the American Society for Testing and Materials (ASTM International) have cooperated for more than 50 years in the preparation of material specifications adequate for safety in the field of pressure equipment. This cooperative

effort originated with metallic materials in ASME BPVC, Section II.

The evolution of this cooperative effort is described in Professor A. M. Greene’s “History of the ASME Boiler Code,” which was published as a series of articles in Mechanical Engineering from July 1952 through August 1953. The following quotations, which are based on the minutes of the ASME Boiler and Pressure Vessel Committee, are taken from Professor Greene’s history and illustrate the cooperative nature of the specifications found in ASME BPVC, Section II, Material Specifications:

“General discussion of material specifications comprising [Paragraphs] 1 to 112 of Part 2 and the advisability of having them agree with ASTM specifications.” (1914)

“An ASME Subcommittee . . . was appointed to confer with the American Society for Testing Mate- rials.” (1916)

“Because of this co-operation the specifications of the 1918 Edition of the ASME Boiler Code were more nearly in agreement with ASTM specifications. . . . In the 1924 Edition of the Code, ten speci- fications were in complete agreement with ASTM specifications, four in substantial agreement, and two covered materials for which the American Society for Testing Materials had no corresponding specifications. . . .

“In Section II, Material Specifications, the paragraphs were given new numbers, beginning with S- 1 and extending to S-213.” (1925)

“Section II was brought into agreement with changes made in the latest ASTM specifications since 1921.” (1932)

“The Subcommittee on Material Specifications . . . arranged for the introduction of the revisions of many of the specifications so that they would agree with the latest form of the earlier ASTM Speci- fications.” (1935)

1 Construction, as used in this Foreword, is an all-inclusive term comprising materials, design, fabrication, erection, examination, inspection, testing, and overpressure protection.

This cooperation has continued with the ASME NPPS Standards. ASME NM.3.1 and ASME NM.3.2 contain many material specifications that are similar to the corresponding ASTM specifications but that have been modified for use in accordance with an ASME construction standard.2 Many of these specifications are published in dual format, i.e., they include both U.S. Customary units and SI units. The metrication protocols followed in the specifications are those adopted by ASTM, and they usually conform to the requirements of IEEE/ASTM SI 10-1997, Standard for the Use of the International System of Units (SI): The Modern Metric System.

In 1992, the ASME Board of Pressure Technology Codes and Standards endorsed the use of non-ASTM material for ASME BPVC applications with the intent that ASME’s procedures and practices for the adoption of ASTM material be used for the adoption of non-ASTM materials. ASME committees continue to consider materials for use in ASME applications; see Mandatory Appendix IV for guidance on the approval of new materials.

ASME material specifications identical to those of the originating organization are identified by both the ASME symbol and the originating organization’s symbol. The specifications prepared and copyrighted by ASTM and other originating organizations are reproduced in this Standard with the permission of the respective organization. The NPPS Committee has carefully considered each new and revised specification, and has made such changes as deemed necessary to adapt the specification for use in accordance with an ASME construction standard. In addition, ASME has furnished ASTM with the basic requirements that should govern many proposed new specifications. Joint action will continue an effort to make the ASTM and ASME specifications identical.

ASME NM.3.1-2018 was approved by the American National Standards Institute (ANSI) on August 16, 2018.

2 ASME construction standards include the ASME B16 series of standards, the ASME B31 Code for Pressure Piping, ASME BPVC, ASME NM.1, ASME NM.2, and ASME RTP-1.

The Committee welcomes proposals for revisions to this Standard. Such proposals should be as specific as possible, citing the paragraph number(s), the proposed wording, and a detailed description of the reasons for the proposal, including any pertinent documentation.

Proposing a Case. Cases may be issued to provide alternative rules when justified, to permit early implementation of an approved revision when the need is urgent, or to provide rules not covered by existing provisions. Cases are effective immediately upon ASME approval and shall be posted on the ASME Committee web page.

Requests for Cases shall provide a Statement of Need and Background Information. The request should identify the Standard and the paragraph, figure, or table number(s), and be written as a Question and Reply in the same format as existing Cases. Requests for Cases should also indicate the applicable edition(s) of the Standard to which the proposed Case applies.

Interpretations. Upon request, the NPPS Standards Committee will render an interpretation of any requirement of the Standard. Interpretations can only be rendered in response to a written request sent to the Secretary of the NPPS Standards Committee.

Requests for interpretation should preferably be submitted through the online Interpretation Submittal Form. The form is accessible at https://go.asme.org/InterpretationRequest. Upon submittal of the form, the Inquirer will receive an automatic e-mail confirming receipt.

If the Inquirer is unable to use the online form, he/she may mail the request to the Secretary of the NPPS Standards Committee at the above address. The request for an interpretation should be clear and unambiguous. It is further rec- ommended that the Inquirer submit his/her request in the following format:

Subject: Cite the applicable paragraph number(s) and the topic of the inquiry in one or two words. Edition: Cite the applicable edition of the Standard for which the interpretation is being requested.

Question: Phrase the question as a request for an interpretation of a specific requirement suitable for general understanding and use, not as a request for an approval of a proprietary design or situation. Please provide a condensed and precise question, composed in such a way that a “yes” or “no” reply is acceptable.

Proposed Reply(ies): Provide a proposed reply(ies) in the form of “Yes” or “No,” with explanation as needed. If entering replies to more than one question, please number the questions and replies.

Background Information: Provide the Committee with any background information that will assist the Committee in understanding the inquiry. The Inquirer may also include any plans or drawings that are necessary to explain the question; however, they should not contain proprietary names or information.

Requests that are not in the format described above may be rewritten in the appropriate format by the Committee prior to being answered, which may inadvertently change the intent of the original request.

Moreover, ASME does not act as a consultant for specific engineering problems or for the general application or understanding of the Standard requirements. If, based on the inquiry information submitted, it is the opinion of the Committee that the Inquirer should seek assistance, the inquiry will be returned with the recommendation that such assistance be obtained.

ASME procedures provide for reconsideration of any interpretation when or if additional information that might affect an interpretation is available. Further, persons aggrieved by an interpretation may appeal to the cognizant ASME Committee or Subcommittee. ASME does not “approve,” “certify,” “rate,” or “endorse” any item, construction, proprietary device, or activity.

Attending Committee Meetings. The NPPS Standards Committee regularly holds meetings and/or telephone confer- ences that are open to the public. Persons wishing to attend any meeting and/or telephone conference should contact the Secretary of the NPPS Standards Committee.
