The Fifth Edition of Standards for Steam Jet Vacuum Systems builds
on the Fourth Edition's integration and update of three previous
HEI documents: Standards for Jet Ejectors, Standards for Field Testing,
and Construction Standards for Steam Jet Ejector Components. In
addition to describing equipment types, the document covers nomenclature,
operating principles, terminology and design specifications (including
suction, discharge and utility conditions). The standard contains
not only performance requirements, but also construction standards
such as materials, welding, quality assurance, shipping, structural
design, hydrostatic testing and tolerances. A section on troubleshooting
and additional information on operational characteristics have been
added to assist users in understanding the equipment.
