Overview
SIST EN ISO 11961:2019/A1:2020 is an important amendment to the international standard governing steel drill pipes used in the petroleum and natural gas industries. Published by the European Committee for Standardization (CEN) and aligned with ISO technical committee ISO/TC 67, this amendment updates the specifications originally set in ISO 11961:2018. It focuses on enhancing the quality, safety, and performance standards for steel drill pipes, which are critical components in exploratory and extraction equipment for oil and gas drilling.
This standard is applicable throughout the European Union and CEN member countries, which include Austria, France, Germany, the United Kingdom, and many others. SIST EN ISO 11961:2019/A1:2020 must be adopted as a national standard by January 2021, ensuring consistency across jurisdictions while supporting the petroleum sector’s evolving technological requirements.
Key Topics
-
Steel Drill Pipe Specifications
The amendment refines the mechanical and chemical requirements for steel drill pipes, ensuring reliability and durability under high-pressure and high-stress environments encountered in drilling operations.
-
Manufacturing and Quality Control
It emphasizes stringent manufacturing processes and quality assurance protocols, including enhanced material testing and inspection criteria, to reduce failure risks during operation.
-
Technical Diagrams and Figures
This amendment includes updates to technical drawings and figures (such as the replacement of Figure B.14 c) Solid Barstock), which provide clearer guidance for manufacturers and engineers on correct drill pipe construction.
-
Conformity and Compliance
The document highlights the need for conformity with national regulations and the avoidance of conflicting standards, facilitating smoother international trade and regulatory approvals.
-
Patent and Intellectual Property Considerations
Users are notified of potential patent rights associated with some elements of the standard, reflecting the innovative nature of drilling technology.
