15-26-630 Containers – Valves and piping.

   Valves, fittings and accessories connected directly to the container, including primary shutoff valves, shall have a rated working pressure of at least 250 pounds per square inch gauge and shall be of material and design suitable for liquefied petroleum gas service. Cast iron shall not be used. Vapor piping with operating pressures not exceeding 125 pounds per square inch gauge shall be designed for that pressure. Vapor piping over 125 pounds per square inch gauge shall have a working pressure of at least 250 pounds per square inch gauge. All valves, fittings, accessories and piping shall be protected from mechanical injury.

(Coun. J. 12-9-92, p. 25465; Amend Coun. J. 2-7-96, p. 15616)

15-26-640 Containers – Relief valves.

   All liquefied petroleum gas containers shall be provided with a spring-loaded safety relief valve as required by National Fire Protection Association Pamphlet No. 58 entitled “Standard for the Storage and Handling of Liquefied Petroleum Gas”, 1973 Edition.

(Coun. J. 12-9-92, p. 25465; Amend Coun. J. 2-7-96, p. 15616)

15-26-650 Excess flow valves.

   An excess flow valve shall be installed wherever required by National Fire Protection Association Pamphlet No. 58 entitled “Standard for the Storage and Handling of Liquefied Petroleum Gas”, 1973 Edition.

15-26-680 Gas hoses.

   All hose used inside buildings as a part of a liquefied petroleum gas system shall be of a type tested and approved by a recognized testing laboratory and be so marked. The maximum length of hose used inside a building on a salamander shall not exceed 20 feet and a shutoff valve shall be provided just ahead of the hose connection. Connections shall be tight and be capable of withstanding five times the working pressure to which they are subject. All hose shall be protected from mechanical injuries.
