The size of the gas pipe needed for a propane stove typically depends on the distance from the propane tank to the stove and the BTU (British Thermal Units) rating of the stove. It is recommended to consult a licensed plumber or gas fitter to ensure the correct size pipe is used for the specific setup to ensure proper gas flow and safety.
Pipe that meets the requirements of sour gas service per NACE MR0175.
To run 400,000 BTU over a distance of 100 feet, you typically need a 2-inch gas pipe. This size accommodates the required gas flow while minimizing pressure drop. However, it's essential to check local codes and regulations, as they may have specific requirements or recommendations. Additionally, factors such as the type of gas and elevation can affect the final pipe size.
A black iron gas pipe sizing chart provides information on the recommended pipe size based on factors like gas flow rate, pressure, and distance. It helps determine the appropriate pipe size for safe and efficient gas distribution in a system.
Need more info to give correct pipe size. Gas company, plumber/pipefitter, or HVAC contractor should be able to assist with sizing.
Orange pipe is for natural gas.
You will need a copy of the International Fuel Gas Code to start with. Turn to table 402.2 to get the BTU ratings for the appliances being installed, then turn to section 402.4 for the formulas to calculate your demand in cubic feet per hour, then turn to tables 402.4 (1-33) and choose the pipe material you want to use, the design pressure, and length of pipe to find the pipe size.
pipe
That would depend on the developed length and the local code and the specific graviety of the gas
Pipe size refers to the diameter of the pipe (in inch).
I don't know what the NEC - OR 2011 is. Is that a code book for the state of Oregon? The NEC does not allow using a gas pipe as a grounding electrode. You run the risk of heating the gas to explosive temperatures.
You need to determine the: gas heater size for the specific pool/spa (with spa use no less than 400,000 BTU). ( how fast do you want the spa to heat to temp?) length of the gas run from the gas meter to the heater pad. size of the gas meter size of the gas pipe at a minimum. Ken
