### Residential New Construction 2 PSIG Program | SoCalGas

The use of 2 PSIG pressure will typically result in 1/2- or 3/4-inch pipe for this run compared to the 1or 1-1/4-inch pipe commonly used in low-pressure systems. Once inside the dwelling unit, a line regulator reduces the natural gas pressure to the traditional 8-inch WC.

### Natural Gas Pipe Sizing (Pressure Drop) Question : Pluing

For the same length pipe, if you flow more gas, the pressure drop will be higher (more friction), so that''s why the cf/h increases with the pressure drop. You really do need to worry about pressure loss, especially when using 1/2 inch iron pipe. The pressure drop is pretty much constant with pipe length at some particular flow rate.

### How to Connect Gas Pipe Lines

If the flare fitting on the flexible stainless gas line matches the size of the flare fitting on the existing gas valve, you can simply screw it on. If the fittings don’t match, one solution is to replace the valve with one that has a flare fitting on one side and a 1/2-in. pipe thread on the other side.

### Co Author #03-12 Block ia, Jalan Sri Perkasa 2 Piping

Proper pipe sizing is determined by the length of the pipe and the allowable pressure drop in the line. The allowable pressure drop may be influenced by factors, including process requirements, economics, safety, and noise or vibration limitations. This guideline also covers other piping related equipment, such as valve, fittings and orifices

### Pressure drop evaluation along pipelines - PetroWiki

One of the most important parameters affecting pressure drop in piping systems is pressure loss in the fittings and valves, which is incorporated in the system. For piping systems within production facilities, the pressure drop through fittings and valves can be much greater than that through the straight run of pipe …

### Flow and pressure drop in valves and fittings. Valve

Another coefficient K v is used in some countries, particularly in Europe and is defined as flow rate of water in m 3 /h that creates pressure drop of 1kg/cm 2 across the valve (1 kg/cm 2 is equal to 0.980665 bar). Control valve sizing is based on the calculation of flow coefficient for given pressure drop …

### Equivalent length of pipe fittings for plastic and steel pipe

The definition of the Equivalent Length of a pipe fitting is the length of pipe of the same size as the fitting that would give rise to the same pressure drop as the fitting. It has been found experimentally that for a given type of fitting (e.g. a long radius elbow) the Equivalent Length (L e ) is larger for larger fittings.
