What is ISO 13679 about?
ISO 13679 is a standard that covers procedures for testing of casing and tubing connection in petroleum and natural gas industries that ensures operational safety and performance in the drilling and extraction process.
ISO 13679 specifies tests to perform in order to determine the galling tendency, sealing performance and structural integrity of casing and tubing connections. “Casing” and “tubing” apply to the service application and not to the diameter of the pipe.
ISO 13679 covers the testing of connections for the most commonly encountered well conditions. Not all possible service scenarios are included. For example, the presence of a corrosive fluid, which can influence the service performance of a connection, is not considered.
Who is ISO 13679 for?
ISO 13679 on testing of casing and tubing connections is applicable to:
- Component manufacturers for oil and gas industries
- Quality and safety assessment services in oil and gas industries
- Testing consultants
- Manufacturers of Casing and tubing
Why should you use ISO 13679?
Tubing and casings in petroleum and natural gas industries are subject to loads that include internal pressure, external pressure, axial tension, axial compression, bending torsion, transverse forces and temperature changes. The magnitude and combination of these loads result in various pipe body and connection failure modes.
ISO 13679 provides you with thread connection performance parameters that include dimensional tolerances, mechanical properties, surface treatment, make-up torque which ensures leak proof operations.
ISO 13679 is developed based on inputs from leading users, manufacturers and testing consultants around the world which ensures the authenticity and validity of the testing for casing and tubing connections.
Guidance in ISO 13679 enables you to produce and assess casing and tubing connections that should meet the necessary limit loads and performance requirements ensuring their safety and operational integrity in petroleum and natural gas industry applications.
What’s changed since the last update?
BS EN ISO 13679:2019 supersedes BS EN ISO 13679:2006, which is now withdrawn.
Changes in BS EN ISO 13679:2019 include -
- New specimen geometries, e.g. XH-XL have been added
- All Connection Assessment Level(s) test requirements and sequences have been revised
