The intersection of these values indicates the acceptable length of the run or the resulting pressure at the appliance. It is important to note that these charts typically assume standard natural gas pipe materials, such as black steel or approved CSST, and may require derating for extreme temperatures or specific insulation scenarios.
How to Size Liquid Propane Piping for Your System Design
Undersized piping creates excessive pressure drops that prevent appliances from reaching full power, while oversized lines represent an unnecessary capital expense and can lead to sluggish gas velocity that promotes condensate accumulation. Additionally, the total British Thermal Units (BTU) load of all connected appliances must be summed to determine the required flow rate in gallons per hour.
Interpreting the Sizing Chart Standard engineering charts for liquid propane are organized by columns representing pipe diameter and rows representing the calculated load or flow rate. The primary goal is to balance flow capacity against pressure loss to ensure that a 100,000 BTU heater at the end of a 100-foot run performs identically to one connected directly to the manifold.
Liquid Propane System Design Sizing and Flow Rate Calculation
Understanding Pressure Drop and Velocity Pressure drop is the reduction in pressure that occurs as gas moves through the pipe due to friction between the gas and the pipe wall. The length of the run is the most obvious variable, as friction loss accumulates over distance.
