API 5L-0552

Certificate No : 5L-0552

Issuing authority : The American Petroleum Institute

Valid period : 2020/5/25 - 2024/6/15

Scope

1. PURPOSE AND COVERAGE
The purpose of this specification is to provide standards for pipe suitable for use in conveying gas, water, and oil in both the oil and natural gas industries.
This specification covers seamless and welded steel line pipe. It includes plain-end, threaded-end, and belled-end pipe, as well as through-the-ftowline (TFL) pipe and pipe with ends prepared for use with special couplings.
Although the plain-end line pipe meeting this specification is primarily intended for field makeup by circumferential welding, the manufacturer will not assume responsibility for field welding.

2. PRODUCT SPECIFICATION LEVEL (PSL)
This specification establishes requirements for two product specification levels (PSL I and PSL 2). These two PSL designations define different levels of standard technical requirements. PSL 2 has mandatory requirements for carbon equivalent, notch toughness, maximum yield strength, and maximum tensile strength. These and other differences are summarized in Appendix 1.
Requirements that apply to only PSL I or only PSL 2 are so designated. Requirements that are not designated to a specific PSL apply to both PSL I and PSL 2.
The purchaser may add requirements to purchase orders for either PSL I or PSL 2, as provided by the supplementary requirements (Appendix F) and other options (4.2 and 4.3).

3. GRADES
The grades (see the note) covered by this specification are the standard Grades A25, A, B, X42, X46, X52, X56, X60, X65, X70 and X80; and any intermediate grades (grades that are higher than X42, intermediate to two sequential standard grades, and agreed upon by the purchaser and manufacturer).
PSL I pipe can be supplied in Grades A25 through X70.
PSL 2 pipe can be supplied in Grades B through X80.
Class II (CI II) steel is rephosphorized and probably has better threading properties than Class I (CI l). Because Class II (CI II) has higher phosphorus content than Class I (CI l), it may be somewhat more difficult to bend.
Pipe manufactured as Grade X60 or higher shall not be substituted for pipe ordered as Grade X52 or lower without purchaser approval.
Note: The grade designations are dimensionless. Grades A and B do not include reference to the specified minimum yield strength; however, other grade designations are composed of the letter A or X, followed by the first two digits of the specified minimum yield strength in U.S. Customary units.

4. DIMENSIONS
The sizes used herein are dimensionless designations, which are derived from the specified outside diameter as measured in U.S. Customary units, and provide a
convenient method of referencing pipe size within the text and tables (but
not for order descriptions). Pipe sizes 23/8 and larger are expressed as integers and fractions; pipe sizes smaller than 23/8 are expressed to three decimal places. These sizes replace the "size designation" and the "nominal size designation" used in the previous edition of this specification. Users of this specification who are accustomed to specifying nominal sizes rather than 00 sizes are advised to familiarize themselves with these new size designations used in this specification, especially the usage in Tables 4, 5, and 6A.
PSL I pipe can be supplied in sizes ranging from 0.405 through 80.
PSL 2 pipe can be supplied in sizes ranging from 4'/2 through 80.
Dimensional requirements on threads and thread gages, stipulations on gaging practice, gage specifications and certification, as well as instruments and methods for inspection of threads are given in API Standard 5B and are applicable to threaded products covered by this specification.

ISO 45001

Certificate No : 19817SH040R1M

Issuing authority : Beijing XInjiyuan Certification Co., Ltd

Valid period : 2020/8/24 - 2023/8/24

ISO 45001

The Final Draft International Standard (FDIS) of ISO 45001, the Occupational Health and Safety Management System standard was published in late November with the final version to be published in February/March 2018. The final standard will be published with only very minor changes to the FDIS version. This is the third in a series of blogs, in which we will describe what the implementing company must do in order to meet the requirement of the draft standard. We will look at clause 4.3: Determining the scope of the OH&S management system.

OH&S management system

Clause 4.3: Determining the scope of the OH&S management system

Clause 4.1 requires the organization to understand the internal and external issues that can impact in a positive or negative manner on its health and safety performance including, inter alia, organizational culture and structure, and the external environment including cultural, social, political, legal, financial, technological, economic, market competition and natural factors of significance to its performance.

Clause 4.2 requires the organization to identify relevant interested parties and their needs and expectations.

Once the organization has determined and assessed its internal and external issues and identified the needs and expectations of relevant interested parties, including its workforce, it should then define the boundaries and applicability of the OH&S management system. The scope of the OH&SMS can include the whole organization, or specific and identified functions or sections of the organization. Therefore, if the organization makes a statement that it conforms to ISO 45001, then it must make the scope of the management system available so that interested parties clearly understand what parts of the organization are covered.

The scope of the management system should include everything under the organization’s control or influence that could impact its OH&S performance. The credibility of the organization’s OH&S management system will largely depend on the extend of the defined boundaries. Under no circumstances should the scope be used to exclude activities, products or services that have or could have the potential to impact the organization’s OH&S performance, or to evade its legal and other requirements.

An inappropriately narrow or exclusive scope could undermine the credibility of the organization’s OH&S management system with its interested parties and reduce its ability to achieve the intended outcomes of the occupational health and safety management system.

The scope is a factual statement of the organization’s operations or business processes to be included within its OH&S management system boundaries.

Once the scope is defined, the concept of ‘organization’ is limited to what the scope covers, e.g. if the scope of the OH&S management system is limited to a particular function or section of the organization, the remainder of the organization is then considered to be an external provider or other interested party.

The organization should maintain the scope of OH&S management system as documented information and make it available to interested parties. There are several methods for so doing, e.g. using a written description, inclusion on a site map, an organizational diagram, a webpage, or posting a public statement of its conformity. When documenting its scope, the organization should consider using an approach that identifies the activities or processes involved, the products or services that ensue, and the location(s), where they occur.
