MODUK DEF STAN 02-878 PDF

This Standard is to advise and inform the selection of tubes and pipes for the transport of liquids and gases within HM Submarines and Surface Ships not in Class. It specifies the requirements, inspection and testing for non-ferrous tubes and pipes. The Standard replaces five specific alloy Standards (Def Stans 02-749 Part 3, 02-779 Part 3, 02-780 Part 3, 02-831 Part 3 and 02-837) but retains the procurement aspects of these documents in appropriate Annexes. Def Stan 02-831 covering aluminium alloy tubes, has been found not to contain performance critical requirements or important component sizing data and so these Standards have been superseded by this Defence Standard, but not replaced by separate Annexes of this Defence Standard. Requirements for the procurement of steel tubes and pipes are specified in Def Stan 02-864. Def Stan 02-878 only applies to non-nuclear systems.
