All process piping, power piping, pipelines all are examples of pressure piping. As a result, considerable thinner piping systems can be designed using Chapter IX when the material has a high yield strength to tensile strength ratio. Exposure of the structural attachments to the buildings of the anchorages or guides shall not be required where the inspection reveals no improper movement or defects in the system. American Legal Publishing and the jurisdiction whose laws are being translated do not vouch for the accuracy of any translated versions of such laws. The Commissioner shall cause the joints in potentially hazardous locations such as those which are located adjacent to tenant occupied spaces to be relocated, unless means exist or are provided for eliminating the hazard. Thank you for this information dear collegue! (ii)The anchorage and guides shall be inspected annually. This shall be followed up by the filing of the application and obtaining the approval specified above. Some guidance is provided in K300 (a), which states that High pressure is considered to be pressure in excess of that allowed by the ASME B16.5 PN 420 (Class 2500) rating for the specified design temperature and material group. This is not a requirement, and the base Code may be satisfactorily used at pressures higher than ASME B16.5, PN 420 (Class 2500). Further, there are few engineering design firms that a properly qualified to design such systems. (1)All expansion joints, anchorage and guides which are presently not accessible to permit a complete visual inspection, shall be made accessible. High pressure piping is the piping that owner designate as being high pressure fluid service. high-pressure and high-temperature fluids designed to operate at more than 250 degrees Fahrenheit and 30 p.s.i.
