BS EN 10208-2:2009 Steel pipes for pipelines for combustible fluids. Technical delivery conditions. Pipes of requirement class B BS EN 10208-2 is the European standard that specifies the technical delivery conditions for seamless and welded steel pipes for the on land transport of combustible fluids primarily in gas supply systems but excluding pipeline applications in the petroleum and natural gas industries. It includes more stringent quality and testing requirements than those in BS EN 10208-1 . Steel pipes for pipeline transportation systems within the petroleum and natural gas industries are covered by ISO 3183 . BS EN 10208-2 specifies products with the same (and additional) strength levels and partly similar (but not identical) requirements as EN 10208-1 and EN 10208-2 and is with two additional annexes specifying deviating or additional requirements also published as API Spec 5L. BS EN 10208-2 does not apply to cast steel pipe. It was the intention, when preparing this document, to avoid specifying the quality of line pipe to be used for a particular application. However, it was recognized that there are several quality levels commonly used, and it was decided to reflect these in the standard by the differentiation between two quality levels. Firstly, the need was recognized to provide a basic quality level. This is designated requirement class A and considered in BS EN 10208-1 . Secondly, many purchasers impose requirements additional to the basic standard, for instance concerning toughness and non-destructive inspection. This approach is common, for example, for transmission pipelines. Such enhanced requirements are addressed in requirement class B and considered in BS EN 10208-2 . For offshore applications and other applications outsi...
