Natural Gas Pipe Sizing In past projects I sized fuel gas pipes in Excel using methods described in IFGC section 402 using either branch-length or longest-length method. I used equations listed in 402.4 (one for under 1.5 psi, one for above 1.5 psi). they also have tables.

Natural gas line sizing calculated in this post will be from manual calculation and from process simulator. API RP 14E is used as reference. Based on API RP 14E, single-phase gas lines should be sized so that the resulting end pressure is high enough to satisfy the requirements of the next piece of equipment .

50 natural gas through the pipe. As you can quickly see, if we sized the gas line to only carry 100 Ft3 of natural gas, then we’d never be able to get 100,000 BTU/hr from the furnace because not enough fuel is arriving at the appliance. The gas line must be sized 1

Task: Calculate the pressure drop generated by the natural gas at a flow rate of 200 Sm3/h through a pipe with nominal diameter of 2 inch and a length of 200 m. The gas temperature is 5 C, the surface roughness of the pipeline is 0.02 mm. Along the pipeline are 5 elbows R=1.5D, 90 deg. Pressure on the pipeline start is 2 bar gauge.

24/6/2014· Using the calculator, why it not just use 54, the water column of 2 psi natural gas? Clearly there is a very good reason but I don''t understand it. I suspect it relates to your statement , "Figure 12 inches into regulator should be more than enough to get 6 inch WC out, I presume."

Hello, I have a question on sizing medium pressure gas pipe. Here is the information: 1. The total gas load is approximately 17,000,000 BTU which equals to 17,000 CFH. 2. Equipments minimum working pressure is 5 inch.H20 and maximum working pressure is 56

3/4/2017· With elevated pressure natural gas service, natural gas from the meter to each unit is sent at 2 pounds-per-square inch (2PSI) pressure. Once inside the apartment, a step-down line regulator reduces the gas pressure to the traditional one-third PSI since residential appliances are designed to burn natural gas only at low pressure.

The pipe size of each section of gas piping shall be determined using the longest length of piping from the point of delivery to the most remote outlet and the load of the section. [NFPA 54:6.1.1] FIGURE 1316.1.1 EXAMPLE ILLUSTRATING USE OF TABLE 1308.4.1 AND TABLE 1316.2(1) Problem: Determine the required pipe size of each section and outlet of the piping system shown in Figure …

2 PSI Systems work on 2 sPE100 ISO9001es, the first sPE100 ISO9001e starts at the gas meter or LPG pipes regulated at 2 psi and ends at the Pounds to Inches regulator at a manifold the end of the “Trunk Line”, the allowable pressure drop on this sPE100 ISO9001e is 1.0 – 1.5 PSI. The pound to Puhui Pipe manufacturer in China

I chose the following for the 2 psi sizing. 2" main 30 psi from Gas hdpe pipes 2" line teed to 2 - 2" branches; 1st run 100'' 2" line BTU/hr requirement ~7 million; 2" continuing on additional 400''with a ~400K BTU/hr requirement. 2nd run 200'' 2" line BTU/hr
