This standard is appr~ved for use by the Naval Sea Systems Command and the standard is published to establish the requirements for piping system components on surface ships, in order to preclude the necessity for including a piping schedule in each Navy Ship SpecLficati~n. Tlaisstandard represents and includes the latest material requirements previously covered in the Ship Specifications. It is the intent to refer co this standard in section 505 In the Ships Specifications for qll new Navy surface ships. 2. Beneficial co=ents (recommendations, additions, deletions) ad any pertinent data which may be of use in improving this document sh?~jd be addressed to: ~nder, Naval Sea Systems Co~, 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. /’” ii KIL-STD-777E(SM) 7 February 1986 1. SCOPE 1.1 Scope. This standard covers requirements for basic piping system components on Navy surface IIhtps. It la not the intention herein to include every conceivable component, valve, or fitting that might be used in the piping system of a surface ship. The requirements invoked herein are not desirable goals but are minimum acceptable standards. 1.2 This standard is broken down into basic semice categories and groups. The notes contained in each individual category end group and prefaced with the category and group designation, apply only to that specific category qnd group. General requirements are also Zncluded to supplement the spectfic category and group notes. General requirements apply to all service categories qnd groups where the content of the requirement is applicable. 1.3 ‘1’hla standard is bound so that qny category .and group can be removed and replaced with revised issues of that category and group. It is intended that changes, *hen required, will be made to individual categories and groups only, rather-than i.sauea complete revision of the standard. Changes will be issued as notices and will be numbered consecutively. 1.4 This standard includes a list of categories and groups with the latest date of issue for each category and group. When a category and group is revised the list of categories and groups will also be revised and will be forwarded for Insertion in the users copy of the standard. 1.5 This standard shall be maintained with all superseded categories and groups and list of categories and groups intact to aesure that when users are applying the standard to requirements which may predate current category and group issues, the applicable issues will be available. 2.
