Overview
EN ISO 10405:2006 (ISO 10405:2000) provides recommended practices for the care and use of casing and tubing in the petroleum and natural gas industries. Endorsed by CEN and prepared by ISO/TC 67, this standard covers safe and effective procedures for running, pulling, handling, inspecting, storing, reconditioning and field welding of casing and tubing used in wells.
Keywords: EN ISO 10405:2006, ISO 10405, casing and tubing care, oil and gas standards, casing handling and storage.
Key Topics
- Running and pulling procedures
- Preparation and inspection before running (thread protection, nondestructive inspection awareness)
- Drifting, stabbing, making up, lowering and landing procedures
- Field makeup and recovery techniques
- Causes of casing/tubing trouble
- Common damage modes and operational causes that lead to failure or reduced service life
- Transportation, handling and storage
- Recommendations to avoid thread and body damage during transport, lifting and on-site storage
- Inspection and classification of used pipe
- Visual and measured inspection criteria, wall and threaded-joint condition assessment, and service rating for reuse
- Reconditioning and repair
- Guidance for acceptable reconditioning practices prior to reuse
- Field welding of attachments
- Requirements and recommended processes for welding attachments to casing (preparation, filler materials, preheating/cooling and technique)
- Reference to normative documents
- Cross-references to relevant standards and bulletins (e.g., ISO 10400, ISO 10422, ISO 11960 / API Spec 5CT, API bulletins, AWS welding guidance)
Applications
- Who uses this standard
- Drilling and completion engineers, wellsite supervisors, operations and maintenance teams, QA/QC inspectors, tubular goods inspectors, and procurement/logistics personnel.
- Practical value
- Reduces risk of downhole failure by standardizing thread care, makeup and landing procedures.
- Improves safety and efficiency in running and pulling operations.
- Supports decisions on reconditioning versus scrap by providing inspection and classification guidance.
- Ensures proper handling, transport and storage to prolong service life and avoid costly damage.
- Provides welding controls for field attachments to maintain structural integrity.
Related Standards (if applicable)
- ISO 10400 - formulas and calculations for tubular properties
- ISO 10422 - threading, gauging and thread inspection of casing and tubing
- ISO 11960 / API Spec 5CT - steel pipes for casing and tubing
- Relevant API and AWS bulletins/specifications for thread compounds, performance properties and welding electrodes
This standard is essential for any organization managing casing/tubing lifecycle in oil and gas wells, offering practical guidance to protect tubular integrity and ensure safe, reliable well operations.
