4 Application 4.1 This Technical Report is intended to be used as a guideline for: a) the incorporation of technical welding requirements into API Product Specifications; b) the creation or modification of welding controls by manufacturers and/or fabricators; c) the identification of welding methodologies that are not currently addressed in API Product Specifications; d) organizations working to the quality management system requirements of API Specification Q1 in conjunction with or independent of the API Monogram Program;e) organizations that primarily focus on national welding codes and standards other than ASME Section IX and/or AWS D1.1, even though these requirements (ASME/AWS) may be specified in API Product Specifications; f) providing a better understanding of welding to auditors who audit API specified requirements, such as: — API Product Specification requirements; — API Specification Q1, Specification for Quality Programs for the Petroleum, Petrochemical and Natural Gas Industry; — API Advisory 8 requirements; — conformity to ASME Section IX and/or AWS D1.1 through the use of national or regional welding criteria. 4.2 This Technical Report could be used to harmonize welding requirements across all API Product Specifications and/or Recommended Practices, with the mitigation of risk associated with welding processes in mind. 4.3 The consideration and implementation of the comprehensive requirements of this Technical Report could assist user organizations to achieve a robust welding program.5 Approach 5.1 General The approach used to develop the Welding Benchmark Criteria (Table 2) included the following considerations and activities (clauses 5.2 through 5.7): 5.2 Welding Requirements Identified in API Product Specifications A cursory analysis of the selected API Product Specifications (Table 1) concluded that there would be minimal value in creating a matrix of the welding requirements currently specified in existing documents. Purpose: Existing specification requirements were perceived as being inconsistently deployed between API Product Specifications. Specifications such as API 6A included robust, detailed requirements, whereas specifications such as API 2C contained lesser, high-level requirements. 5.3 API Specification Q1 Requirements The requirements of API Specification Q1, 8 th Edition and 9 th Edition, were considered during the development of the output shown in this Technical Report. Table 3 identifies the Q1 requirements for the validation of welding processes. Purpose: There is a direct interaction of the Q1 quality management system requirements and the welding processes identified in API Product Specifications and/or the requirements for the organizations that perform welding, whether licensed under the API Monogram Program or that have a quality management system certification to Q1 and/or ISO 9001.5.4 API Monogram Program Advisories The requirements of the API Monogram Program Requirements, Advisory 8, Implementation and Maintenance of Quality Management System Requirements, were considered since this advisory requires licensees to apply their quality management system requirements to non-monogrammable products if said products are to be used in the oil and gas industries. Shown below is a partial excerpt of Advisory 8’s wording: “It is a program requirement that all licensees must maintain a quality program in conformance with the requirements of API Specification Q1 for all products at all times. All API product specification requirements are applicable to the specific products manufactured and/or services provided in conformance with those specifications, including API-monogrammed equipment. However, a quality management system in conformance with the API Spec Q1 is to be applied to all products and services of the petroleum, petrochemical and natural gas industries, at all times, whether or not these products or services carry the API Monogram. This policy is in accordance with the API’s objective of supporting a high standard of quality, environmental, and health performance expectations for the petroleum, petrochemical and natural gas industry.”API TR 18TR4 pdf download.
