Re: [MW:4066] Transition (pup pipes) testing requirments

specifications do not adress this clearly. in my view you should always test as per linepipe spec for anything formed into a pipe whether it be from a forging, plate or API 5L linepipe. in reality though they are often treat as assemblies omiting additional fracture control for linepipe

Pipelines are subject to the rigours of fracture control e.g. ductile
fracture via impact energy absorption and brittle fracture via shear
area fracture appearance. This is often done by CVN and DWT.

Should pup pieces made up from API 5L xx linepipe be subjected to the
same tests? Or should they by tested only via impact energy absorption
as are the fittings to which they are attached.
