What is EN 11960？

European Standard EN ISO 11960 Petroleum and Natural Gas Industry Steel Pipe Relevant Information

Summary

The European standards that involve steel pipes for the oil and gas industry are the EN ISO 11960 series standards. This standard specifies the technical delivery conditions for steel pipes (casing, tubing, and short sections), coupling blanks, coupling materials, and accessory materials, and specifies the requirements for three product specification levels (PSL-1, PSL-2, PSL-3), of which PSL-1 is the basis of this international standard.

Different version situations

ISO 11960:2001

This version is an early version with the standard name "Steel Pipe for Oil and Gas Industry Oil Well Casing and Tubing", but the specific technical content updates of this version are not mentioned in detail in the search materials.

ISO 11960:2004

This version is also an international standard developed by the International Organization for Standardization to standardize the requirements for the manufacturing, inspection, and labeling of steel casing or tubing used in the oil and gas industry. It is specifically stipulated that the material of casing or tubing should be high-quality carbon structural steel or low-alloy structural steel, and appropriate heat treatment and surface treatment processes should be adopted during the manufacturing process to ensure its mechanical properties and surface quality. The size of casing or tubing should comply with a certain tolerance range and have clear markings for easy identification. This standard is of great significance for the safety and reliability of steel casing or tubing used in the oil and gas industry, and also specifies relevant certification procedures to ensure that casing or tubing that meets the standard can guarantee the safety of workers and environmental protection.

EN ISO 11960:2011

The technical delivery conditions for steel pipes (casing, tubing, and short sections), coupling blanks, coupling materials, and accessory materials have been specified, and requirements for three product specification levels (PSL-1, PSL-2, PSL-3) have been established. All steel grades except H-40, L-80 9Cr, and C110 have defined different levels of standard technology for PSL-2 and PSL-3.

EN ISO 11960 - 2014

The Chinese standard name is "Petroleum and natural gas industries - Steel pipes for use as casing or tubing for wells", and the English standard name is "Petroleum and natural gas industries - Steel pipes for use as casing or tubing for wells (ISO 11960:2014)". The standard covers a wide range of content, including preface, introduction, scope of application, consistency, normative reference documents, terminology definitions, symbols and abbreviated terms, information to be provided by the purchaser, manufacturing process, material requirements, dimensions, quality, tolerances, product ends and defects, couplings, inspection and testing, marking, coating and protection, documents, low facility requirements for different types of manufacturers, etc. There are also multiple appendices to supplement relevant content, such as purchaser inspection, International System of Units unit tables, International System of Units (US customary unit system) unit graphics, etc.

standard meaning

These standards are of great significance for the safety and reliability of steel casing or tubing used in the oil and gas industry. They stipulate requirements for manufacturing, inspection, and labeling to ensure that these pipelines comply with relevant safety standards and regulations, thereby guaranteeing the safety of workers and environmental protection. By specifying different product specifications and grades, it is possible to meet the requirements for steel pipe quality and performance under different working conditions and demands.
