CHAPTER 12. LUBRICANTS, SEALANTS, AND CLEANING
PROCEDURES FOR HYPERBARIC SYSTEMS
1.
SCOPE. This chapter provides information in Section 1 for use in
selecting lubricants and sealants and in Section 2 for use in selecting the
cleaning method and procedures to be used in the hyperbaric systems to
maintain the Navy standards.
Section 1. LUBRICANTS AND SEALANTS
1.
LUBRICANTS AND SEALANTS. A limited number of the many lubricants and
sealants which may be used in hyperbaric systems are listed in Tables 12-1
through 12-6. Conventional readily available lubricants and sealants are
almost always based on various forms of hydrocarbon products. However, in
the high pressure air or oxygen environments of hyperbaric systems,
hydrocarbon products present very serious fire hazards.
The needs of the chemical industry, medical research, the diving industry,
and the space program have prompted manufacturers to develop many lubricants
and sealants which are safe for use in high oxygen environments. Although a
wide range of acceptable, safe products with very useful special properties
are available, these products are sometimes difficult to locate unless the
manufacturers and the trade names are known. These lists should aid the
designer, fabricator, and user of hyperbaric systems in selecting and
obtaining products which meet their requirements.
This information was obtained from Government reports, military
specifications, qualified products lists, and commercial suppliers.
