34、trial site NOTE 1A piping system can be regarded as one single system provided it conveys substances having the same properties and it is as a whole designed for the same allowable pressure. NOTE 2Interruption by different components such as pumps, machines, vessels etc. does not preclude the integr
35、ation to one single piping. 3.1.3 fluid gases, liquids and vapours in pure phase as well as mixtures thereof NOTE: A fluid may contain a suspension of solids. 3.1.4 manufacturer person or organization that takes full responsibility for the design and manufacture of the piping system and its conformi
