A valve may not be used under operating conditions that exceed the applicable pressure-temperature ratings contained in those requirements. (b) Each cast iron and plastic valve must comply with the following: (1) The valve must have a maximum service pressure rating for temperatures that equal or exceed the maximum service temperature; (2) The valve must be tested as part of the manufacturing, as follows: (A) With the valve in the fully open position, the shell must be tested with no leakage to a pressure at least 1.5 times the maximum service rating; (B) After the shell test, the seat must be tested to a pressure not less than 1.5 times the maximum service pressure rating. Except for swing check valves, test pressure during the seat test must be applied successively on each side of the closed valve with the opposite side open. No visible leakage is permitted; (C) After the last pressure test is completed, the valve must be operated through its full travel to demonstrate freedom from interference; (3) Each valve must be able to meet the anticipated operating conditions; (4) No valve having shell components made of ductile iron may be used at pressures exceeding eighty percent of the pressure ratings for comparable steel valves at their listed temperature. However, a valve having shell components made of ductile iron may be used at pressures up to eighty percent of the pressure ratings for comparable steel valves at their listed temperature, if: (A) The temperature-adjusted service pressure does not exceed 1,000 p.s.i.g.; and (B) Welding is not used on any ductile iron component in the fabrication of the valve shells or their assembly; (5) No valve having pressure containing parts made of ductile iron may be used in the gas pipe components of compressor stations.

Four expressly reserved section slots are inventory-only. The PUC's April 2026 page links a 160-page signed scan; an official 178-page text-layer copy from Budget and Finance is used as the higher-quality transcription aid. The publication is an April 15, 1994 adoption, filed August 24 and effective September 3, 1994, based on the October 1, 1990 federal text; it is not a current restatement of federal pipeline standards.", "applicability": "Hawaii is not represented as certified, as an agreement state, or as an interstate agent under the PHMSA federal-state pipeline safety program. PHMSA states that its Office of Pipeline Safety inspects and enforces federal pipeline safety regulations for interstate and intrastate gas and hazardous-liquid pipelines in Hawaii. Chapter 6-77 may remain relevant as published state utility material, but it must not be used to infer current Hawaii inspection or enforcement authority.", "currentness": "The Hawaii PUC still links Chapter 6-77 on its official rules page, updated April 2026. Hawaii's official 2022 periodic rules-review report separately says Chapter 6-77 is to be repealed, was superseded by statute and a federal takeover letter, and cites 2009 Act 25. Because the PUC page does not mark the chapter repealed, this connector preserves the published text with an explicit superseded/slated-for-repeal warning rather than declaring an unproved completed administrative repeal.", "incorporation": "The chapter repeatedly identifies the October 1, 1990 edition of 49 CFR Parts 191 and 192 and its appendices as the implemented source. That fixed, obsolete baseline is preserved exactly. Current federal text, later amendments, and current editions of incorporated private standards must not be silently substituted when researching what this publication says.", "excludedScope": "This connector excludes HAR Chapter 6-83 one-call damage prevention, utility rates and service standards, statutes as standalone documents, dockets, orders, tariffs, federal text, current federal amendments, and the full text of incorporated private standards. Those materials require separate completeness, currentness, applicability, and rights analysis.", "rights": "Official Hawaii and PHMSA artifacts are retained with attribution and SHA-256 provenance. Public access does not establish unrestricted rights in site presentation, state marks, forms, or incorporated private standards. The connector records citations to private standards but makes no independent rights claim for those works." }, "region": "HI" } ```
