While iron is no longer the preferred material used in water piping, it’s application has converted over to gas systems. Because the amount of oxygen is limited in gas applications, the pipes are less likely to corrode in this type of system. When hooking up a gas system composed of iron piping, there are a few things to consider about choosing the right type of pipe fittings for the installation process.
One of the things to consider with Iron Pipe Fittings is the shape of the connection that you need. The angle of the two connecting pipes can help to determine the shape of the connection needed. Some angles may have to be measured first if they are not obvious. While the ninety degree angle is the most common for turns, there are a few situations in which a forty-five degree angle is more compatible with the system installation.
Another thing to consider is the diameter of the piping. In order to fit into the system properly, the pipe fitting must be of the same diameter as the rest of the piping. If this fitting is used to transition from one size of piping to another, you will need to check both diameters. In addition, make sure the units of the diameter are the same since metric units are of a slightly different size than standard units.
Take a look at the threads of the Iron Pipe Fittings as well. Consider the placement of the threads and whether you need a male or female fitting for the system. This also requires that you look at the actual piping installed in the system to help make this determination. In some cases, both types of thread placements will be needed. If this is the case, you will need a fitting that can accommodate both types of threading. Check this feature before you buy.
These are the things to look at with iron fittings. Even though iron is no longer used in main water systems, it is still used in many gas applications. Check out website domain for the different types of iron fittings available.
