Overview
EN ISO 13085:2014 (ISO 13085:2014) specifies the technical delivery condition, manufacturing process, material requirements, configuration and dimensions, and verification and inspection procedures for aluminium alloy pipe for use as tubing for wells in the petroleum and natural gas industries. Endorsed by CEN, this international standard provides consistent requirements for production, testing and documentation of aluminium well tubing intended for oil and gas applications.
Key Topics and Requirements
The standard addresses the full lifecycle of aluminium alloy well tubing, including:
- Material requirements: classification of material groups, chemical composition limits and metallographic examination.
- Manufacture & delivery: process of manufacture, heat treatment, delivery condition and traceability requirements.
- Mechanical properties: tensile properties and related test procedures.
- Configuration & dimensions: pipe configuration, lengths, dimensional tolerances, design mass, upset run-out, straightness, ovality, eccentricity and drift requirements.
- Coatings & corrosion: internal coating considerations and corrosion testing procedures.
- Testing & inspection: defined test methods and measuring methods, purchaser inspection options (Annex A) and corrosion test (Annex B).
- Quality assurance & documentation: marking, packaging, transport and storage, certification, retention of records and minimum mill facility requirements.
These elements ensure consistent product quality, fitness for purpose and traceability from manufacturer to end user.
Applications
EN ISO 13085 is directly applicable where aluminium alloy tubing is specified for well operations in petroleum and natural gas fields. Common practical applications include:
- Tubing for production strings in onshore and offshore wells.
- Tubing material selection where aluminium alloy properties (weight, corrosion behavior) are favorable.
- Procurement specifications and supplier qualification for aluminium well tubing.
- Inspection and acceptance testing during manufacturing and receipt.
Using the standard helps reduce procurement risk, supports regulatory compliance and standardizes acceptance criteria across projects.
Who Uses This Standard
- Oil & gas operators and engineering firms specifying tubing for wells.
- Manufacturers and mills producing aluminium alloy pipe for well applications.
- Quality, inspection and testing laboratories performing metallurgical, mechanical and corrosion tests.
- Procurement and certification bodies managing delivery documentation and traceability.
