Gas piping and sizing

Gas Hub House is a great resource if you need to know about resouces about gas. Pipe sizing is a very important consideration in natural gas piping. During deliberation of pipe sizing, it should be ensured that the gas pressure at the inlet is sufficient enough to feed the appliance. The system’s capacity is also very essential in pipe sizing. While piping natural gas it is also a requirement that at minimum flow of the gas, the inlet pressure of an appliance should not exceed the one regulated. The design of the piping system supposed to be of a particular size such that when installed, is sufficient enough to meet the maximum demand of gas supplied. It should also allow for maintenance of pressure between the gas utilization equipment and delivery point of the gas. The following are considered when gas piping and sizing.

1. Pipe sizing charts or prescribed sizing equations.

2. The sizing tables that is included in a listed piping system’s manufacture’s installation equipment.

3. Accepted engineering methods.

The maximum gas demand is usually determined by adding all of the equipment Btu ratings from appliances that are connected to the piping system. Sizing charts are comprised in the Gas Code where all the fundamental information on how to size most gas systems is entailed. There are also software that is developed for the purpose of designing and sizing fuel gas piping systems. When one is sizing gas piping, the gas pressure at the delivery point should be determined. The best way of checking the gas pressure at the meter is by consulting a gas supplier. This information is essential as it allows one to use the correct sizing chart in the gas Code.

The flow of natural gas streams in thousands of Btu per every hour. With this conversion, one can have an idea when dealing with natural gas pipe sizing chart. Each fitting should be given an additional five feet of pipe. Before using any equation while sizing natural gas piping system, the plans should be stamped by a licensed mechanical engineer. There are two types of sizing equations; low-pressure gas equation and high-pressure gas equations. High-pressure is considered to be above 1.5psi (10.3KPa). The variables in the equations are factors such as the inside diameter of the pipe, the input rate of the appliances, upstream and downstream pressure and pressure drop. Natural gas pipe sizing chart is also determined by longest length method. This means that each section of the gas piping is determined by using the longest length of piping from delivery point to the most remote outlet and the load of the section. http://www.gashubhouse.com
