COOLERS, FLUID, NAVAL SHIPBOARD – HYDROCARBON BASE OIL AND FRESHWATER SERVICES
|Publication Date:||9 June 2021|
This specification covers naval shipboard, fluid coolers for use in hydrocarbon base oil and freshwater services for which standards of resistance to shock and standards of construction are higher than for usual commercial marine use.
The coolers described in this specification are intended for use in lubrication, hydraulic, and freshwater systems aboard Navy surface ships and submarines for the cooling of hydrocarbon-based... View More
The coolers described in this specification are intended for use in lubrication, hydraulic, and freshwater systems aboard Navy surface ships and submarines for the cooling of hydrocarbon-based oils and fresh water. No one cooler is intended to cool more than one of these three categories of fluid in any one application. The coolers are divided into two types according to their design and to whether the fluid to be cooled is the inner fluid or outer (see 1.2). The coolers are also divided into five classes according to whether they are for use on submarines or surface ships, whether they use seawater or fresh water as a cooling medium, and whether or not they are to be subjected to seawater pressure at depths greater than 200 feet (see 1.2). Coolers of type I may be of any class; coolers of type II may be of any class except class 1. Current stock of the coolers may be used until depleted; future requisitions for the coolers should refer to the current version of this specification.View Less
