ISO 11961:2018/Amd 1:2020 PDF

Overview

ISO 11961:2018/Amd 1:2020 is an official amendment to the international standard for steel drill pipe used in the petroleum and natural gas industries. Developed by ISO Technical Committee ISO/TC 67, Subcommittee SC 5, this amendment updates the third edition of ISO 11961, originally published in October 2018. It ensures that specifications for steel drill pipe reflect the latest technological advancements and industry requirements for reliability and safety during drilling operations.

The steel drill pipes covered under this standard are critical components in oil and gas exploration and production, involved in drilling wells and transmitting torque and drilling fluids between the surface and the drill bit. This amendment includes updates such as the revision of graphical figures illustrating solid barstock used in pipe manufacturing, contributing to clearer technical guidance.

Key Topics

• Scope and Purpose Focuses on steel drill pipe characteristics relevant to the petroleum and natural gas sectors, reinforcing manufacturing quality and material performance standards.

• Technical Revisions Incorporates changes to graphical representations in Annex B (specifically the replacement of Figure B.14 c), ensuring precision in manufacturing standards and documentation.

• Standardization Process Developed under ISO/IEC Directives with contributions from national standard bodies and industry experts, ensuring global applicability.

• Intellectual Property and Compliance Includes important notes on patent rights related to the document’s content and emphasizes the voluntary nature of ISO standards.

Applications

• Oil and Gas Drilling Operations Steel drill pipes manufactured to this standard are essential in onshore and offshore drilling rigs, ensuring safe and efficient drilling performance.

• Equipment Manufacturing Pipe manufacturers rely on ISO 11961 specifications for producing steel drill pipes that meet international quality and safety benchmarks.

• Quality Assurance and Testing The standard supports QA processes by providing clear, updated technical guidelines that ensure material integrity and consistency across global suppliers.

• Engineering and Design Engineers use this amendment as a reference to design drilling systems with compliant steel drill pipes, optimizing operational safety and equipment lifespan.
