2 of 107 9/13/2016 4:08 PM Second Revision No. 20-NFPA [ Detail ] In Section , change "Schedule 40" to "Schedule 10" In Table A.5.6, make the following changes to the Material column under Pipe: Material Pipe Black Steel Minimum Schedule Galvanized Steel Minimum Schedule Wrought Iron Minimum Schedule Also known as low iron or wrought steel Stainless Steel Minimum Schedule 10 Submitter Information Verification Submitter Full Name: Laura Montville Organization: [ Not Specified ] Street Address: City: State: Zip: Submittal Date: Wed Jun 22 12:11:43 EDT 2016 Committee Statement Committee Statement: The schedule 40 restriction was in place to safely accommodate threading of pipe. Allowing schedule 10 acknowledges different pipe joining methods. The revision will allow Schedule 10 pipe to be used for fuel gas piping in buildings. Schedule 10 pipe has a thinner wall than Schedule 40 and therefore is lighter and has a higher gas flow than Schedule 40. Schedule 10 pipe is currently allowed for fuel gas piping at pressures above 125 psig by ASME B31.1, Power Piping. As it is allowed for higher pressure than covered by the scope of the National Fuel Gas Code there is technical reason to not allow the material in NFPA 54. Due to the thinner wall of Schedule 10 pipe it cannot be threaded, and must be joined by other methods such as press connect fittings, welding, and other means. The revision does not limit the means of joining schedule 10 pipe other than not allowing threading. Schedule 10 pipe, while thinner than Schedule 40, has sufficient strength to withstand damage during installation. It should be sufficiently robust to not be dented, pinched, or punctured in normal installations in buildings. Because of the thinner wall, the inside diameter of Schedule 10 pipe is greater than Schedule 40. This results in a higher gas flow capacity of approximately 6 %. The

3 2 of 107 9/13/2016 4:08 PM current Schedule 40 pipe sizing tables can be used or a note can be added to the table to allow flow to be increased by 6% where Schedule 10 is used. Response Message: The existing table of pipe hanger spacing can be used for Schedule 10 pipe as the pipe is lighter than Schedule 40 pipe.

4 3 of 107 9/13/2016 4:08 PM Switzer, Jr., Franklin R. Negative with Comment Feehan, Pennie L. The statement that schedule 10 pipe is difficult to get and will not be sold in big box stores is not a good argument! It reminds me of the CSST s promised the big box stores would not carry this product and it would only be sold to plumbers that were certified to install. Today, CSST is sold in Lowes and Home Depots. Section 1.4 allows jurisdictions to approve schedule 10 whenever they choose. Once the code is changed, there will be no control on where schedule 10 pipe is installed or sold. These products will be available to use by anyone, including homeowners. Ribbs, Phillip H. I strongly disagree with this proposal. No scientific justification was presented to address internal and external corrosion affects to steel pipe as requested by the TC in their previous meeting. I have met with gas utility suppliers from Southern Nevada and Pacific Gas & Electric. Both suppliers recommend that Schedule 40 remain the minimum requirement for steel gas piping systems. The San Bruno, CA gas line failure which resulted in loss of lives and millions of dollars of property was sighted. I met with Viega (Pro-Press) representatives at the ASHE Expo. They reported no issues with Schedule 40 joining methods. Viega representatives have given presentations, which I attended, in Utah and Nor-Cal at UAPMO and IAPMO inspector chapter meetings stating the same successes. I met with design-build contractors and code enforcement officials who reported having no issues or failures with Schedule 40 installations. Lastly, the potential for the general public to improperly install Schedule 10 pipe will be greatly enhanced by this proposal. I believe there was no justification presented for the current level of health and safety to be reduced. Abstention Griffith, Roger W Recently appointed to TC. I think it would be best for me not to vote on the Second Revisions. I would prefer to be a part of the discussions and understand the reasons behind the proposed revisions.

This revision does not add "gas" to piping systems because that would be redundant based on the scope of the code. This revision also does not add "system" because the requirements are meant to apply only to a portion of the piping system (for example the portion in a ventilated chase), not the system as a whole.

28 27 of 107 9/13/2016 4:08 PM Second Revision No. 21-NFPA [ Section No ] * Pipe Joints. Pipe Schedule 40 and heavier pipe joints shall be threaded, flanged, brazed, welded, or assembled with press-connect fittings listed to ANSI LC 4/CSA 6.32, Press-Connect Metallic Fittings for Use in Fuel Gas Distribution Systems. Where nonferrous pipe is brazed, the brazing materials shall have a melting point in excess of 1000 F (538 C). Brazing alloys shall not contain more than 0.05 percent phosphorus. (A) Pipe lighter than Schedule 40 shall be connected using press-connect fittings, flanges, brazing, or welding. (B) Where nonferrous pipe is brazed, the brazing materials shall have a melting point in excess of 1000 F (538 C). (C) Brazing alloys shall not contain more than 0.05 percent phosphorus. Submitter Information Verification Submitter Full Name: Laura Montville Organization: [ Not Specified ] Street Address: City: State: Zip: Submittal Date: Wed Jun 22 12:19:06 EDT 2016 Committee Statement Committee Statement: The schedule 40 restriction was in place to safely accommodate threading of pipe. Allowing schedule 10 acknowledges different pipe joining methods. The revision will allow Schedule 10 pipe to be used for fuel gas piping in buildings. Schedule 10 pipe has a thinner wall than Schedule 40 and therefore is lighter and has a higher gas flow than Schedule 40. Schedule 10 pipe is currently allowed for fuel gas piping at pressures above 125 psig by ASME B31.1, Power Piping. As it is allowed for higher pressure than covered by the scope of the National Fuel Gas Code there is technical reason to not allow the material in NFPA 54. Due to the thinner wall of Schedule 10 pipe it cannot be threaded, and must be joined by other methods such as press connect fittings, welding, and other means. The revision does not limit the means of joining schedule 10 pipe other than not allowing threading. Schedule 10 pipe, while thinner than Schedule 40, has sufficient strength to withstand damage during installation. It should be sufficiently robust to not be dented, pinched, or punctured in normal installations in buildings. Because of the thinner wall, the inside diameter of Schedule 10 pipe is greater than Schedule 40. This results in a higher gas flow capacity of approximately 6 %. The current Schedule 40 pipe sizing tables can be used or a note can be added to the table to allow flow to be increased by 6% where Schedule 10 is used. The existing table of pipe hanger spacing can be used for Schedule 10 pipe as the pipe is lighter

31 30 of 107 9/13/2016 4:08 PM Second Revision No. 7-NFPA [ Section No ] Where Required. A line pressure regulator or gas appliance pressure regulator, as applicable, shall be installed where the gas supply pressure exceeds the maximum allowable inlet pressure of the appliance served Listing. Line pressure regulators shall be listed in accordance with ANSI Z21.80/CSA 6.22, Line Pressure Regulators, where the outlet pressure is set to 2 psi or less. Submitter Information Verification Submitter Full Name: Laura Montville Organization: [ Not Specified ] Street Address: City: State: Zip: Submittal Date: Tue Jun 21 13:40:16 EDT 2016 Committee Statement Committee Statement: "Gas appliance pressure regulator" was removed because appliance regulators do not fall under the scope of the code. The intent of a line pressure regulator listed in accordance with ANSI Z21.80/CSA 6.22 has to do with an installation where the appliance is rated for 0.5 PSI (typically this is an appliance listed to any one of the ANSI Z21/83 series standards) and the supply pressure is greater than 0.5 PSI. Listing to ANSI Z21.80/CSA 6.22 should be required only when its outlet pressure is 2 PSI or less.
