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

Use of Code Book Sizing Tables The sizing tables are based on a nuer of factors. The main factor is gas pressure of the system. The tables cover pressures up to 50 pounds(psi) for schedule 40 pipe materials and up to 5 pound for semi rigid tubing and

Capacity Table for NATURAL GAS (2 PSI service) Capacity Table for LPG PROPANE GAS (2 PSI service) The chart links above show the BTU capacity of a pipe size at given length increments.

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 mm. Along the pipeline are 5 elbows R= , 90 deg. Pressure on the pipeline start is 2 bar gauge.

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.

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
