Can you oversize a gas pipe?
You can flow only so much gas (or water) through a given pipe size, so restrictions will manifest themselves as a lack of pressure or volume. Sizing a gas line is not too difficult. The main pipe size will increase as a branch is added and increase again as another branch is added.

Is gas pipe measured ID or OD?
OD and Nominal Pipe Size Tubing is measured by the OUTSIDE DIAMETER (O.D.), specified in inches (e.g., 1.250) or fraction of an inch (eg. 1-1/4″). Pipe is usually measured by NOMINAL PIPE SIZE (NPS). Although it is related to the outside diameter, it is significantly different.

Can a pool heater be too big?
One of the important parts of putting in a pool heater is making sure it is the correct size to maintain the comfortable temperature you want. However, there is no such thing as oversizing a pool heater. The larger the heater’s output, the faster it heats the water in the pool, and it will not begin short-cycling.
What happens if you oversize a pipe?
Oversized piping may contribute to health risks such as Legionella, sewage clogs, and odor fade. As time moves forward, plumbing fixtures and the use of plumbing systems changes, and new risks are discovered and studied.
What happens when you increase pipe size?
The diameter of pipe and flow rate: It flows faster, which increases the flow rate. And if the diameter increases, then the flow rate reduces.
What size is residential gas line?
Some homes are only equipped with gas lines that are 3/4 inch (“) in diameter, as this is a standard size for supporting major appliances. Other homes may have a combination of 1-inch, 1/2-inch, and 3/4-inch gas lines.
How many BTUs can a 1 pipe deliver?
Natural Gas Example: A burner that requires 374,000 BTU would need a 1” pipe for a 30′ long run. Liquid Propane gas flow is given in thousands of BTU/hour. One cubic foot of LP gas = 2516 BTU’s.
How many BTUs can a 15mm pipe carry?
From the limiting factors, it is estimated that 15mm copper pipe can handle 13,620 BTU; so 15mm can easily cope. Then looking at the pipework for the hall and lounge radiators, this has to carry the heat for both radiators (2751 + 4687 = 7,438 BTU), so again 15mm pipe will cope.
