In its most simple form, three pipe fittings are connected between a hot source (usually a natural gas flame) and a cold source.

A thermostatically controlled valve provides a regulated pressure differential between the heated and cold pipes.<br><br><br>Nominal Pipe Size (NPV) is a North American standard set of standardized sizes for pipes generally used for low or high temperatures and pressures. Pipe size is measured using two non-determined numbers: a non-determined nominal pipe size (NDV) based on standard inches, and a scheduled pipe fitting size (SCL). The NDFV refers to the maximum achievable pipe pressure, while SCL is the minimum achievable pipe temperatures. The schedule pipe configuration is used to control the flow of liquid through pipes.<br><br><br>The difference between PVCu and NDFV is that the PVCu pipe is manufactured with a one-half inch NDFV, while the NDFV is only recommended for use in temperature and pressure ranges greater than or less than 55 degrees Fahrenheit. The difference between SCLu and SSCLu pipes is that the latter has a one-inch schedule pipe wall thickness. Schedule pipe wall thicknesses are only required in the United States, where a pipe wall thickness of a quarter of an inch is the common standard.<br><br><br>Both NDFV and SCLu pipe materials are available in a variety of materials. Stainless steel pipe and fittings are the most common types for commercial applications, as they are available in both standard and nominal sizes. For residential applications, the most common pipe and fittings materials are standard and nominal sizes. Other materials, such as natural gas and ferric, are also becoming more popular because of their relative ease of installation.<br><br><br>Pipe and fittings can be purchased in both standard and nominal size sizes, depending on the pipe or fitting intended. When purchasing steel pipe and fittings, it is important to consider pipe and fittings intended for installation in different types of structures, including walls and floors. In other words, if you are installing a pipe in a wall, floor, or ceiling, you will need a different size than if you were installing it in a floor or table. Another way to determine the size of pipe needed is based upon the wall thickness.<br><br><br>The outside diameter of a pipe is the outside diameter of the inside of a wall or ceiling, while the outside diameter of a table or floor is the outside diameter of a straight wall. The inside diameter of a wall is typically larger than that of a table or floor because the pipe size must be smaller than the inside diameter to pass through a house or building's interior. You may find that you need to use different pipe sizes to connect different parts of your house or building. For example, if you are replacing a kitchen sink, you would likely need a larger pipe than you would to connect the sink to the faucet. Your local plumbing contractor can help you determine the correct pipe size for the specific job.<br>
