It is vital that all gas piping design is 100% compliant with the relevant legislation and current codes including the National Fuel Gas Code, the Fuel Gas Code of New York State, and the NYC Fuel Gas Code.
The scope of each document is defined in each of the codes.
So, for example, the NFGC applies to the installation of all fuel gas piping systems and the equipment and appliances that are manufactured for use with natural gas, manufactured gas, LPG which is used in its vapor phase only, LPG-air mixtures, various other gas mixtures, and flammable gas-air mixtures. Storage, handling, and use of LPG are not included in the NFGC but rather in the more specific Liquefied Petroleum Gas Code (LPGC).
The NYC Fuel Gas Code (NYCFGC) applies to the installation of fuel gas piping systems as well as fuel gas appliances and accessories required for systems and appliances. More specifically, the scope of the Code as it relates to gas piping installations governs every aspect from design to installation, modification, and maintenance of fuel gas piping systems. This, in turn, includes acceptable design, suitable materials and components, fabrication, assembly, installation, testing and inspection, as well as the operation and maintenance of piping systems.
While the scope of the chapter on gas piping installations in the NYS code is essentially the same as the NYC Code, the scope of the chapter on general requirements is much more complex. This code is based on the International Fuel Gas Code with amendments, all of which are found in this section which is titled the New York State Uniform Fire Prevention and Building Code. The provisions of this “Uniform Code” apply to all new and existing buildings and structures, with a few exceptions.
Additionally, the scope of the NYS’s Uniform Code relates to various specified international codes:
- The Residential Code that deals with detached one- and two-family houses as well as townhouses that aren’t above three stories in height, as well as one-family houses that have been converted to bed and breakfast establishments where the owner lives and offers five or fewer guest rooms.
- The Building Code.
- The Plumbing Code.
- The Mechanical Code that, amongst other things, deals with energy-related systems.
- The Fuel Gas Code, which of course includes the design of fuel gas piping. Piping systems covered include natural gas with a 125 lb per square inch operating pressure gauge (862 kPa gauge) or less, or LPG with an operating pressure of 140 kPa gauge or 20 psig or less.
- The Fire Code.
- The Property Maintenance Code.
This is all in addition to the myriad of other federal, state, and local laws, ordinances, administrative codes, rules and regulations – which is why our NYE team of gas piping design professionals has a thorough grounding of, and comprehensive experience in dealing with relevant legislation.
