Title
Standard Specification for Spray Shields for Mechanical Joints
ASTM International
Publication Date:
Apr 10, 1998
Scope:
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.
