What size CSST stainless steel tubing is needed to supply 220 cubic feet of natural gas per hour from 34 feet away from the meter?

To determine the appropriate size of Corrugated Stainless Steel Tubing (CSST) needed to supply a specific volume of natural gas, it is essential to consider the volume flow rate, distance from the meter, and pressure drop within the system.

For a flow rate of 220 cubic feet of natural gas per hour and a distance of 34 feet from the meter, calculations or flow rate charts specific to CSST reveal the size of tubing necessary to ensure that the gas can be supplied efficiently without excessive pressure loss.

Based on the established standards and guidelines for CSST installations, using a diameter of 37 is suitable. This diameter allows the gas to maintain adequate pressure and flow rate over the distance specified, ensuring safety and efficiency. The proper sizing also accounts for potential pressure drops that can occur in longer runs of tubing, making it important to use the right diameter to prevent issues such as inadequate supply or operational problems with gas appliances.

In contrast, smaller sizes would lead to higher pressure losses, potentially causing insufficient gas delivery to appliances. Therefore, selecting 37 ensures that the system functions correctly under the specified conditions.
