ANSI API RP 5A5-2005 pdf free download – Field Inspection of New Casing, Tubing, and Plain-end Drill Pipe.
This International Standard specifies requirements and gives recommendations for field inspection and testing of oil country tubular goods (OCTG). This International Standard covers the practices and technology commonly used in field inspection; however, certain practices may also be suitable for mill inspections.
This International Standard covers the qualification of inspection personnel, a description of inspection methods and apparatus calibration and standardization procedures for various inspection methods.
The evaluation of imperfections and marking of inspected OCTG are included. This International Standard is applicable to field inspection of OCTG and is not applicable for use as a basis for acceptance or rejection (for which the relevant purchasing specification is applicable, see 5.4.2).
2 Conformance
2.1 Normative references In the interests of worldwide application of this International Standard, ISO/TC 67 has decided, after detailed technical analysis, that certain of the normative documents listed in Clause 3 and prepared by ISO/TC 67 or other ISO Technical Committee are interchangeable in the context of the relevant requirement with the relevant document prepared by the American Petroleum Institute (API), the American Society for Testing and Materials (ASTM) or the American National Standards Institute (ANSI).
These latter documents are cited in the running text following the ISO reference and preceded by “or”, for example “ISO XXXX or API YYYY”. Application of an alternative normative document cited in this manner may lead to technical results different from the use of the preceding ISO reference. However, both results are acceptable and these documents are thus considered interchangeable in practice. NOTE ISO 11960 has been back-adopted by API as API Spec 5CT. Therefore, for the purposes of the provisions in this International Standard which cite ISO 11960, API Spec 5CT is equivalent to ISO 11960.
2.2 Units of measurement In this International Standard, data are expressed in both the International system (SI) of units and the United States Customary (USC) system of units. For specific field inspection and testing, it is intended that only one unit system be used, without combining data expressed in the other system.
Inspection and testing performed using either of these unit systems shall be considered equivalent and totally interchangeable. Consequently, compliance with the requirements of the relevant Product Standard expressed in one of the unit systems provides compliance with the requirements expressed in the other system. For data expressed in the SI, a comma is used as the decimal separator and a space as the thousands separator. For data expressed in the USC system, a dot (on the line) is used as the decimal separator and a space as the thousands separator.
In the text, data in SI units are followed by data in USC units in brackets.
2.3 Tables and figures Separate tables for data expressed in SI units and USC units are given in Annex A and Annex C, respectively.
For a specific order item, only one unit system shall be used. In this International Standard, cross-references are made only to the tables in Annex A; if the USC units apply on an order, then any cross-references to tables in Annex A shall be taken to mean the equivalent table in Annex C.
Figures (data expressed in both SI and USC units) are contained in Annex B.ANSI API RP 5A5 pdf download.
