SCHEDULE 40 METALLIC PIPE Gas Natural Inlet Pressure Less than 2 psi Pressure Drop 0.3 in. G is gas gravity. One cubic foot of Natural Gas = roughly 1000 BTU Typical nominal pressure at the burner for Natural Gas is 3.5" of water column Typical machine supply pressure is 5" to 7" of water column Pipe length must include additional length for all fittings Add approximately 5 feet of pipe per fitting h( There are 27.7 inches of water column pressure in 1 PSI of pressure. The total gas load is approximately 17,000,000 BTU which equals to 17,000 CFH. 0000007263 00000 n
Table 1 Type Gas - Copper Tube for Gas Installation - Type Gas. The capacity of a low pressure natural gas (less than 1 psi) pipe line can be calculated with the Spitzglass formula like q = 3550 k ( h / l SG)1/2 (1) where For natural gas the nominal BTU/cf varies from about 900 to 1100 BTU/cf . One cubic foot of NG gas = 1000 BTU's. Pipe length must include additional length for all fittings. Le is equivalent length in mile. Fuel gas branch lines under 2, over two, or no pipe size restriction on branch lines with brazing torch station and liquid flashback arrester componentsProtective equipment, including a flashback arrester, is required in fuel gas and oxygen piping systems to prevent a reverse flow of oxygen from flowing back up the fuel gas line, or a reverse flow of fuel gas from flowing back up the oxygen line, also to prevent excessive pressure build-up in the system and stop a flashback from reaching the supply source. 37MXmM pipe gas natural inlet pressure less than 2 psi pressure Drop 0.3.
