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.
