the piping coenpitnents and stniclural inatenals listed in Appendices A and C. It is rot intended to include in this Code complete specitications equipment. Certain details of design and latwication, however, necessarily refer to equipment. such as pipe hangers. vibration dampener’s. electrical facilities, engines. compressors. etc. Partial specilications for such equipment items are given herein, particularly if they affect the satety of the piping system in which they are to he installed. In other case’ where the Code gives no specilications for the particular equipment tlem, the intent as that the safety provisions of the Code shall gosem. insofar as they an applicable. In any ease. the safety of equipment installed in a piping system shall he eqttisalent to that of other puns of the same system.

Any pipe has ing an outer-diameter-to-wall thickness ratio of 70 to I at more, that is to be used in a pipeline at a hoop stress of 20% at more of the speeilled minimum yield strength that has been at will he transported by railroad, inland waterway, at by marine transportation. must have been or shall he loaded in accordance with RPiSLI or API RP5LW, respectively. Where it is not possible to establish that pipe was transported in accordance with the appropriate recontrnendsrd poictice. the pipe must he hydrostatically tested for at least 2 hr to at least 1.25 times the matinium allowable operating pressure if installed in a Class I location, or to at least 1.5 times the maximum allowable operating pressure if installed in a Class 2, 3. at 4 location.
