scope:

Appendix A of this specification establishes basic selection and installation criteria for the application of zinc (type ZEP, ZRN, and ZDM) and iron corrosion preventive anodes to copper, nickel, or iron alloy components of shipboard condensers and heat exchangers. This specification covers the threaded plugs used as support plugs for types ZRN and ZDM zinc anodes conforming to MIL-A-18001 and iron anodes.

The support plugs for heat exchanger zinc or iron anodes shall be of the following types and classes as specified (see 6.2):

Anode designation: Type I - (for use with ZRN or iron anodes). Type II - (for use with ZDM anodes). Plug thread designation: Class A - Straight thread O-ring seal. Class B - Tapered pipe thread (replacement use only not for new construction). Class C - Straight thread O-ring plugs for MS16142 or SAE J 1926 type boss.

Beneficial comments (recommendations, additions, deletions) and any pertinent date which may be of use in improving this document should be addressed to: commander, Naval Sea Systems Command, SEA 55Z3, Department of the Navy, Washington, DC 20362-5101 by using the self-addressed Standardization Document Improvement Proposal (DD Form 1426) appearing at the end of this document or by letter.
