11、eForewordIn December 1931, API and the American Society of Mechanical Engineers (ASME) created the Joint API/ASME Committee on Unfired Pressure Vessels. This committee was created to formulate and prepare for publication a code for safe practices in the design, construction, inspection, and repair o
12、f pressure vessels to be used in the petroleum industry. Entitled API/ASME Code for Unfired Pressure Vessels for Petroleum Liquids and Gases (commonly called the API/ASME Code for Unfired Pressure Vessels or API/ASME Code), the First Edition of the API/ASME Code was approved for publication in 1934.
13、 From its inception, the API/ASME Code contained Section I, which covered recommended practices for vessel inspection and repair and for establishing allowable working pressures for vessels in service. Section I recognized and afforded well-founded bases for handling various problems associated with
14、 the inspection and rating of vessels subject to corrosion. Although the provisions of Section I (like other parts of the API/ASME Code) were originally intended for pressure vessels installed in the plants of the petroleum industry, especially those vessels containing petroleum gases and liquids, t
15、hese provisions were actually considered to be applicable to pressure vessels in most services. ASMEs Boiler and Pressure Vessel Committee adopted substantially identical provisions and published them as a nonmandatory appendix in the 1950, 1952, 1956, and 1959 editions of Section VIII of the ASME B
16、oiler and Pressure Vessel Code.After the API/ASME Code was discontinued in 1956, a demand arose for the issuance of Section I as a separate publication, applicable not only to vessels built in accordance with any edition of the API/ASME Code but also to vessels built in accordance with any edition o
17、f Section VIII of the API/ASME Code. Such a publication appeared to be necessary to assure industry that the trend toward uniform maintenance and inspection practices afforded by Section I of the API/ASME Code would be preserved. API 510, first published in 1958, is intended to satisfy this need.The
18、 procedures in Section I of the 1951 edition of the API/ASME Code, as amended by the March 16, 1954 addendum, have been updated and revised in API 510. Section I of the API/ASME Code contained references to certain design or construction provisions, so these references have been changed to refer to
19、provisions in the API/ASME Code. Since the release of the 1960 edition of the National Board Inspection Code, elements of the API/ASME Code have also been carried by the National Board Inspection Code.It is the intent of API to keep this publication up to date. All pressure vessel owners and operato
20、rs are invited to report their experiences in the inspection and repair of pressure vessels whenever such experiences may suggest a need for revising or expanding the practices set forth in API 510.This edition of API 510 supersedes all previous editions of API 510. Each edition, revision, or addend
21、um to this API code may be used beginning with the date of issuance shown on the cover page for that edition, revision, or addendum. Each edition, revision, or addendum to this API code becomes effective six months after the date of issuance for equipment that is rerated, reconstructed, relocated, r
22、epaired, modified (altered), inspected, and tested per this code. During the six-month time between the date of issuance of the edition, revision, or addendum and the effective date, the user shall specify to which edition, revision, or addendum the equipment is to be rerated, reconstructed, relocat
23、ed, repaired, modified (altered), inspected, and tested.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
24、in the publication be construed as insuring anyone against liability for infringement of letters patent.Shall: As used in a standard, “shall” denotes a minimum requirement in order to conform to the specification.Should: As used in a standard, “should” denotes a recommendation or that which is advis
25、ed but not required in order to conform to the specification.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 conten
26、t of this publication or comments and questions concerning the procedures under which iiithis publication was developed should be directed in writing to the Director of Standards, American Petroleum Institute, 1220 L Street, NW, Washington, DC 20005.
