Air conditioning piping is one of the most important aspects of an air conditioner's installation. Keeping your piping in good condition is necessary to ensure a long lifespan for your unit. It can also save you time and money. The materials used to make your piping should be corrosion-resistant and durable. Depending on the needs of your HVAC system, you may choose to use copper, plastic, or steel. When selecting a material, it's important to remember that pipes that are made of plastic cannot withstand a wide range of temperatures. Plastic piping is more cost-effective than copper, but it isn't as strong as metal. In addition to the materials used for your piping, it is also important to consider the type of installation and the space available for the pipeline. For example, if your home is small, you can install the pipes in the ceiling. However, if your home is larger, you may need to connect indoor and outdoor units with separate piping. Another consideration is the number of bends. This will affect the refrigerant flow. You can determine the flow with a chart or table. There are many factors that will help you determine the amount of bends in your piping, including the tonnage of the equipment, the number of elbows and fittings, and the ambient operating temperature. Once you've determined the size of your piping, it's time to decide on the type of material you'll use. If you need a small system, you may opt for copper. Alternatively, if you need a large, powerful system, you'll need to choose steel. Steel piping offers the ability to handle a variety of pressures, a range of temperatures, and a higher degree of flexibility. Using the correct piping for your air conditioning system will help you save time and money. You'll want to ensure that your piping is properly insulated, and that it is the right size for your home's needs. Having your piping installed by a professional will ensure that the job is done correctly. Also, it's a good idea to check for leaks and damage after the piping has been installed. Some types of piping cover trunking will hide the lines, and protect your AC piping and drain lines from damage. It's especially useful if you have an exposed piping system. These piping covers can add a clean finish to your AC piping, and they are available in several different colors. They can also be fitted to walls to conceal wall-mounted piping. A number of manufacturers also offer prefabricated thermal insulating fitting covers that are made of ASTM C450. If you are installing your piping in an underground application, metallic piping is usually covered with a PVC jacket. If you're looking for an aesthetically pleasing piping system, you may want to consider the Slimduct SD series from Inaba Denko. This piping cover trunking is made of high-quality PVC. It's flame-retardant, weather-proof, and resistant to UV rays. With its high-quality design and durability, it can provide a long service life for your air conditioning system.
