[Gas pipe sizing tables]
• These tables are for reference only. Consult gas pipe manufacturer for actual pipe capacities.
• It is an example of Schedule 40 Metallic Pipe.
• (Only Table 1 - 4)
Values in Table are in ft 3 of Gas per Hour. Contact your gas supplier for Btu/ft 3 ratings. For simplification
of your calculations, 1 ft 3 of Gas is approximately equivalent to 1,000 Btu.
