适用范围：This specification describes the manufacturing requirements for spray shield stock and the fabrication and installation requirements for spray shields made from that stock. Sections 2-14 address the manufacturing requirements for the spray shield stock. Annex A1 addresses the fabrication and installation requirements for the spray shields. Fig. 1 shows the typical construction of a spray shield. Figs. 2-6 show methods of installation of a spray shield on various mechanical joints. The shields are intended for use around mechanical joints (flanged, bolted unions, and so forth) in liquid piping systems to prevent the impingement of flammable liquid on hot surfaces or fluids onto electrical switchboards and components resulting from a leak in the mechanical joint. The values stated in inch-pound units are to be regarded as the standard. The values given in parentheses are for information only.
