SPECIAL NOTES API publications necessarily address problems of a general nature. With respect to particular circumstances, local, state, and federal laws and regulations should be reviewed. API is not undertaking to meet the duties of employers, manufacturers, or suppliers to warn and properly train and equip their employees, and others exposed, concerning health and safety risks and precautions, nor undertaking their obligations under local, state, or federal laws. Information concerning safety and health risks and proper precautions with respect to particular materials and conditions should be obtained from the employer, the manufacturer or supplier of that material, or the material safety data sheet. 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. Generally, API standards are reviewed and revised, reaffirmed, or withdrawn at least every five years. Sometimes a one-time extension of up to two years will be added to this review cycle. This publication will no longer be in effect five years after its publication date as an operative API standard or, where an extension has been granted, upon republication. Status of the publication can be ascertained from the API Upstream Segment [telephone (202) 6828000]. A catalog of API publications and materials is published annually and updated quarterly by API, 1220 L Street, N.W., Washington, D.C. 20005. 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 standard or comments and questions concerning the procedures under which this standard was developed should be directed in writing to the general manager of the Upstream Segment, American Petroleum Institute, 1220 L Street, N.W., Washington, D.C. 20005. Requests for permission to reproduce or translate all or any part of the material published herein should also be addressed to the general manager. API standards are published to facilitate the broad availability of proven, sound engineering and operating practices. These standards are not intended to obviate the need for applying sound engineering judgment regarding when and where these standards should be utilized. The formulation and publication of API standards is not intended in any way to inhibit anyone from using any other practices. Any manufacturer marking equipment or materials in conformance with the marking requirements of an API standard is solely responsible for complying with all the applicable requirements of that standard. API does not represent, warrant, or guarantee that such products do in fact conform to the applicable API standard.

FOREWORD This bulletin is under the jurisdiction of the Subcommittee on Standardization of Tubular Goods. This bulletin is not intended as a design manual. Its purpose is to provide minimum performance properties on which the design of casing, tubing, and drill pipe strings may be based. The performance properties as given herein cover the grades, sizes, and weights of casing, tubing, and drill pipe as given in API Specification 5CT. Formulas and procedures for calculating the values are given in Bulletin 5C3. Formulas and calculations appearing in the 13th and preceding editions of Bull 5C2 were transferred in 1971 to Bull 5C3: Bulletin on Formulas and Calculations for Casing, Tubing, Drill Pipe, and Line Pipe Properties. API publications may be used by anyone desiring to do so. Every effort has been made by the Institute to assure the accuracy and reliability of the data contained in them; however, the Institute makes no representation, warranty, or guarantee in connection with this publication and hereby expressly disclaims any liability or responsibility for loss or damage resulting from its use or for the violation of any federal, state, or municipal regulation with which this publication may conflict. Suggested revisions are invited and should be submitted to the general manager of the Upstream Segment, American Petroleum Institute, 1220 L Street, N.W., Washington, D.C. 20005.

aSome joint strengths listed in Col. 20 through 29 are greater than the corresponding pipe body yield strength listed in Col. 13. bCollapse resistance values calculated by elastic formula. cMinimum internal yield pressure is the lowest of the internal yield pressure of the pipe or the internal yield pressure of the

resistance at the E1 or E7 plane is less than the internal yield pressure at minimum yield. Leak resistance is as follows: dFor J-55 and K55 casing the next higher grade is L-80. For N-80 casing the next higher grade is P-110. For P-110 casing the next higher grade is Q125. No higher grades have been established for other grades.
