Pipelines-Gas and liquid petroleum Part 5: Field pressure testing
|Publication Date:||20 September 2012|
This Standard sets out methods for the pressure testing of petroleum pipelines designed in accordance with AS 2885.1 and operated in accordance with AS 2885.3. It may also be used for testing other pipelines, including pipelines designed to, or operated to, AS 4645.2.
Pressure testing is used to establish-
(a) the pressure limit (PL) in accordance with AS 2885.1 (strength test); and
(b) the leak tightness of a test section (leak test).
Pressure testing with air or a gas whilst not recommended, is permitted by this Standard within the limits nominated in AS 2885.1.
References in this Standard to liquid or fluid may be generically applied as applicable to air or gas.
