pressure exceeds 5 psi (34 kPa) for natural gas and 10 psi (69 kPa) for undiluted propane or is less than 6 inches (1.5 kPa) of water column, or where diversity demand factors are used, the design, pipe, sizing, materials, location, and use of such systems first shall be approved by the Authority Having Jurisdiction. Piping systems designed for pressures exceeding the serving gas supplier’s standard delivery pressure shall have prior verification from the gas supplier of the availability of the design pressure.

FIGURE 1315.1.1 Problem: Determine the required pipe size of each section and outlet of the piping system shown in Figure 1315.1.1. Gas to be EXAMPLE ILLUSTRATING USE OF TABLE 1308.4.1 AND TABLE 1315.2(1) used has a specific gravity of 0.60 and 1100 British thermal units (Btu) per cubic foot (0.0114 kW•h/L), delivered at 8 inch water column (1.9 kPa) pressure.
Solution: (1) Maximum gas demand of OutletA –
32 cubic feet per hour (0.91 m 3 /h) (from Table 1308.4.1). Maximum gas demand of Outlet B – 3 cubic feet per hour (0.08 m 3 /h) (from Table 1308.4.1). Maximum gas demand of Outlet C – 59 cubic feet per hour (1.67 m 3 /h) (from Table 1308.4.1). Maximum gas demand of Outlet D – 136 cubic feet per hour (3.85 m 3 /h) [150 000 Btu/hour (44 kW)] divided by 1100 Btu per cubic foot (0.0114 kW•h/L) (2) The length of pipe from the gas meter to the most remote outlet (OutletA) is 60 feet (18 288 mm). (3) Using the length in feet column row marked 60 feet (18 288 mm) in Table 1315.2(1):
OutletA, supplying 32 cubic feet per hour (0.91 m 3 /h), requires 1 ⁄2 of an inch (15 mm) pipe. Section 1, supplying OutletsA and B, or 35 cubic feet per hour (0.99 m 3 /h) requires 1 ⁄2 of an inch (15 mm) pipe. Section 2, supplying OutletsA, B, and C, or 94 cubic feet per hour (2.66 m 3 /h) requires 3 ⁄4 of an inch (20 mm) pipe. Section 3, supplying OutletsA, B, C, and D, or 230 cubic feet per hour (6.51 m 3 /h), requires 1 inch (25 mm) pipe. (4) Using the column marked 60 feet (18 288 mm) in Table 1315.2(1) [no column for actual length of 55 feet (16 764 mm)]:
Outlet B supplying 3 cubic feet per hour (0.08 m 3 /h), requires 1 ⁄2 of an inch (15 mm) pipe. Outlet C, supplying 59 cubic feet per hour (1.67 m 3 /h), requires 1 ⁄2 of an inch (15 mm) pipe. Using the column marked 60 feet (18 288 mm) in Table 1315.2(1): Outlet D, supplying 136 cubic feet per hour (3.85 m 3 /h), requires 3 ⁄4 of an inch (20 mm) pipe.

Notes: 1 Table entries are rounded to 3 significant digits. 2 Table includes losses for four 90 degree (1.57 rad) bends and two end fittings. Tubing runs with larger numbers of bends, fittings, or both shall be increased by an equivalent length of tubing to the following equation: L = 1.3 n, where L is additional length (ft) of tubing and n is the number of additional fittings, bends, or both. 3 EHD = Equivalent Hydraulic Diameter, which is a measure of the relative hydraulic efficiency between different tubing sizes. The greater the value of EHD, the greater the gas capacity of the tubing.

Notes: 1 Table does not include effect of pressure drop across the line regulator. Where regulator loss exceeds 0.75 psi (5.17 kPa), DO NOT USE THIS TABLE. Consult with regulator manufacturer for pressure drops and capacity factors. Pressure drops across a regulator are capable of varying with flow rate. 2 CAUTION: Capacities shown in table are capable of exceeding maximum capacity for a selected regulator. Consult with regulator or tubing manufacturer for guidance. 3 Table includes losses for four 90 degree (1.57 rad) bends and two end fittings. Tubing runs with larger numbers of bends, fittings, or both shall be increased by an equivalent length of tubing according to the following equation: L = 1.3 n, where L is additional length (ft) of tubing and n is the number of additional fittings, bends, or both. 4 Table entries are rounded to 3 significant digits. 5 EHD = Equivalent Hydraulic Diameter, which is a measure of the relative hydraulic efficiency between different tubing sizes. The greater the value of EHD, the greater the gas capacity of the tubing.

Notes: 1 Table does not include effect of pressure drop across the line regulator. Where regulator loss exceeds 1 psi ( 7 kPa), DO NOT USE THIS TABLE. Consult with regulator manufacturer for pressure drops and capacity factors. Pressure drops across regulator are capable of varying with the flow rate. 2 CAUTION: Capacities shown in table are capable of exceeding the maximum capacity of selected regulator. Consult tubing manufacturer for guidance. 3 Table includes losses for four 90 degree (1.57 rad) bends and two end fittings. Tubing runs with larger numbers of bends, fittings, or both shall be increased by an equivalent length of tubing to the following equation: L = 1.3 n, where L is additional length (feet) of tubing and n is the number of additional fittings, bends, or both. 4 Table entries are rounded to 3 significant digits. 5 EHD = Equivalent Hydraulic Diameter, which is a measure of the relative hydraulic efficiency between different tubing sizes. The greater the value of EHD, the greater the gas capacity of the tubing.

Notes: 1 Table includes losses for four 90 degree (1.57 rad) bends and two end fittings. Tubing runs with larger numbers of bends, fittings, or both shall be increased by an equivalent length of tubing to the following equation: L = 1.3 n, where L is additional length (ft) of tubing and n is the number of additional fittings, bends, or both. 2 Table entries are rounded to 3 significant digits. 3 EHD = Equivalent Hydraulic Diameter, which is a measure of the relative hydraulic efficiency between different tubing sizes. The greater the value of EHD, the greater the gas capacity of the tubing.

Notes: 1 Table does not include effect of pressure drop across the line regulator. Where regulator loss exceeds 0.5 psi (3.4 kPa) [based on 13 inch water column (3.2 kPa) outlet pressure], DO NOT use THIS TABLE. Consult with regulator manufacturer for pressure drops and capacity factors. Pressure drops across a regulator are capable of varying with flow rate. 2 CAUTION: Capacities shown in table are capable of exceeding the maximum capacity for a selected regulator. Consult with regulator or tubing manufacturer for guidance. 3 Table includes losses for four 90 degree (1.57 rad) bends and two end fittings. Tubing runs with larger numbers of bends, fittings, or both shall be increased by an equivalent length of tubing to the following equation: L = 1.3 n, where L is additional length (ft) of tubing and n is the number of additional fittings, bends, or both. 4 Table entries are rounded to 3 significant digits. 5 EHD = Equivalent Hydraulic Diameter, which is a measure of the relative hydraulic efficiency between different tubing sizes.
