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

To determine the appropriate size of CSST (Corrugated Stainless Steel Tubing) needed to supply 220 cubic feet of natural gas per hour from a meter that is 34 feet away, one must consider the flow capacity of the tubing based on both the flow requirement and the distance.

The sizing of gas tubing accounts for the volume of gas needed and the pressure drop that occurs over a certain length of the tubing. When supplying 220 cubic feet per hour, the required tubing size must be capable of delivering this volume without exceeding the pressure drop limits established by safety and building codes.

Calculating the flow capacity for a distance of 34 feet involves using tables or charts that indicate the flow capacities for different sizes of CSST, considering factors such as the type of gas and the specific installation. The size that can adequately handle 220 cubic feet per hour over the given distance is crucial to ensure proper function, safety, and efficiency.

The choice of 37 in this scenario reflects the recognized standards for CSST which indicate that this size provides the necessary throughput without causing excessive pressure loss over that 34-foot distance. Thus, it meets the requirements for providing a consistent supply of gas to the appliance while adhering to regulatory standards.

In contrast, smaller sizes
