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Generally, API standards are reviewed and revised, reaffirmed, or withdrawn at least every five years.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 Standards department telephone (202) 682-8000. A catalog of API publications, programs and services is published annually and updated biannually by API, and available through Global Engineering Documents, 15 Inverness Way East, M/S C303B, Englewood, CO 80112-5776.
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 Director of the Standards department, 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 be addressed to the Director, Business Services.
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.

Specification For Repair And Remanufacturing Of Well Control Equipment 53
1. Scope
1.1 General
This American National Standard specifies requirements for repair, remanufacturing, testing, inspection, welding, marking, certification, recertification, handling, storing and shipping of drill-through equipment used for drilling for oil and gas build under API-16A. When desired this standard can also be voluntary adopted for other well control equipment build under a different specification, but this will not automatically make them API products. This standard defines Repair Service Levels for the below listed equipment and the required equipment traceability that is required to proof compliance. The repair and remanufacturing supported under this standard requires that the associated service conditions of the equipment in terms of internal pressure, temperature and wellbore fluids and ambient temperature limits for which the equipment is designed remains unchanged and is supported by the Original Product Definition.
This American National Standard is applicable to and establishes requirements for the following specific equipment:
a) ram blowout preventers;
b) ram blocks, operators, packers and top seals;
c) annular blowout preventers;
d) annular packing units;
e) hydraulic connectors;
f) drilling spools;
g) adapters;
h) loose connections;
i) clamps.
j) drilling riser
Dimensional interchangeability is limited to end and outlet connections. Typical equipment defined by this American National Standard is shown in Figures 1 and 2.
Recommendations for failure reporting are outlined in Annex B.
This API standard supports the requirements of life cycle management systems for new, individual, API monogrammed products or system parts throughout their functional life cycle.
