Details
1.1 ,This specification provides design and construction criteria for a semi-flush, oiltight and watertight bolted manhole cover assembly.
1.2 ,The manhole cover assembly depicted in this specification is for use in decks or bulkheads requiring oiltight and watertight covers that are not required to be completely flush. Manhole cover assemblies shall be complete with covers, mounting rings, gaskets, welded studs, washers, and nuts.
1.3 ,Handles, if required, shall be as specified in the ordering information.
1.4 ,This specification is not applicable to certain hazardous cargos (see Section 46 CFR 153.254 and 46 CFR 154.340).
1.5 ,This specification provides design and construction for manhole cover assemblies subjected to lateral pressures such as resulting from vehicle loads or hydrostatic pressures. Where manhole cover assemblies are subjected to primary or cyclic loads, other reinforcement or construction criteria may be necessary to integrate the manhole assembly with the required structural reinforcement for openings in decks or bulkheads. Design of the manhole cover assembly for primary or cyclic loads is beyond the scope of this specification.
1.6 ,The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.
1.7 ,This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
Rationale:
This specification provides the design and construction criteria for a semi-flush bolted oiltight and watertight manhole cover assemblies that are subjected to lateral pressures such as resulting from vehicle loads or hydrostatic pressures, and used in decks or bulkheads requiring manhole covers that are not required to be completely flush. Manhole cover assemblies shall be complete with covers, mounting rings, gaskets, welded studs, washers, and nuts. This specification does not address certain hazardous cargos, as well as the design of the manhole cover assembly for primary or cyclic loads.
