Foreword

This specification is under the jurisdiction of the American Petroleum Institute Subcommittee on Fiberglass and Plastic Tubulars. The purpose of this specification is to provide standards for high-pressure fiberglass line pipe and fittings for use in conveying produced fluids including oil, gas, nonpotable water, and mixtures thereof in the oil and gas producing industries.

Nothing contained in any API publication is to be construed as granting any right, by implication or otherwise, for the manufacture, sale, or use of any method, apparatus, or product covered by letters patent. Neither should anything contained in the publication be construed as insuring anyone against liability for infringement of letters patent.

The verbal forms used to express the provisions in this recommended practice are as follows:

• the term “shall” denotes a minimum requirement in order to conform to the recommended practice;

  
  

• the term “should” denotes a recommendation or that which is advised but not required in order to conform to the recommended practice;

  
  

• the term “may” is used to express permission or a provision that is optional; and

  
  

• the term “can” is used to express possibility or capability.

This document was produced under API standardization procedures that ensure appropriate notification and participation in the developmental process and is designated as an API standard. Questions concerning the interpretation of the content of this publication or comments and questions concerning the procedures under which this publication was developed should be directed in writing to the Director of Standards, American Petroleum Institute, 200 Massachusetts Avenue, NW, Suite 1100, Washington, DC 20001. Requests for permission to reproduce or translate all or any part of the material published herein should also be addressed to the director.

Generally, API standards are reviewed and revised, reaffirmed, or withdrawn at least every five years. A one-time extension of up to two years may be added to this review cycle. Status of the publication can be ascertained from the API Standards Department, telephone (202) 682-8000. A catalog of API publications and materials is published annually by API, 200 Massachusetts Avenue, NW, Suite 1100, Washington, DC 20001.

Suggested revisions are invited and should be submitted to the Standards Department, API, 200 Massachusetts Avenue, NW, Suite 1100, Washington, DC 20001, standards@api.org.

Attention Users of this Publication: This edition of API Specification 15HR supersedes the Third Edition and includes items approved by letter ballot. Those ballot approved items (substantive changes) are indicated with gray shading and red font, but API makes no warranty as to the accuracy of such notations. Non-substantive changes will not be indicated. Portions of this publication have been changed from the previous edition. In some cases the changes are significant, while in other cases the changes reflect minor editorial adjustments in order to conform to current API styling. Since the document was significantly reformatted from the previous edition, no attempt was made to indicate the location of changes with bar notations.

   and 100 lbf/in.2 (0.69 MPa)

   This specification was formulated to provide for the availability of safe, dimensionally, and functionally inter- changeable high-pressure fiberglass line pipe with a pressure rating from 500 lbf/in.2 to 5000 lbf/in.2 (3.45 MPa to

   34.5 MPa), inclusive, in 250 lbf/in.2 (1.72 MPa) increments for pipes ≤ than NPS 12 inches

   increments for pipes ˃ than NPS 12 inches. This specification is limited to mechanical connections and the technical content provides requirements for performance, design, materials, tests and inspection, marking, handling, storing, and shipping. Critical components are items of equipment having requirements specified in this document.

   
   

   This specification is applicable to rigid pipe components made from thermosetting resins and reinforced with glass fibers. Typical thermosetting resins are epoxy, polyester, vinyl ester, and phenolic. Thermoplastic resins are excluded from the scope of this specification. Any internal liners applied shall be made also from thermosetting resins. Fiberglass line pipe for use in low-pressure systems are covered in API Spec 15LR.

   
   

   This specification covers fiberglass pipe utilized for the production of oil and gas. Specific equipment covered by this specification is high-pressure line pipe and couplings, fittings, flanges, and reducers and adapters.
