What is the difference between heavy gauge and light gauge pipes?
- Thickness and Form
- Types and Sizes
- Applications and Functions
Pipes have come a long way in building and construction. Back then, only clay pipes were used to carry sewage and supply water. Nowadays, there is a wide variety of pipes that are utilized not only for carrying water but for other applications as well. But all of these are not suitable for use in all situations. There is no one-size-fits-all solution when it comes to choosing a pipe material and type for projects. There are specific uses for each type of pipe, and some are better suited than others. If you are looking into pipes, it’s best to have knowledge on each type to pick the perfect one for you. Today, we’ll be tackling the difference of heavy gauge and light gauge pipes. Continue reading to learn more.
Thickness and Form
When working with pipes, it is common for the term “gauge” to be used. Someone who is unfamiliar with the gauge system may not understand what is meant by heavy and light gauges. When it comes to pipes, the gauge is a description of wall thickness. Typically, the thicker material you choose, the better durability and performance you will attain. Heavy-gauge pipes are the thickest and heaviest out of all the classes. On the other hand, light gauge pipes are the lightest gauge pipes you will encounter.
Types and Sizes
There are many types of heavy and light gauge pipes such as cast iron, copper, plastic, stoneware, and more. Although there are two types of pipes that are mostly used– galvanized steel (GI) pipes or black iron pipes.
Galvanized pipes are made from steel pipes. These pipes are dipped in a protective layer of zinc coating to act as a barrier for corrosion and dust. These pipes are classified into three classes: light, medium, and heavy.
Black iron pipes are made out of steel. Unlike galvanized pipes, these pipes are not coated with any substrate like zinc or pain during the manufacturing process.
Applications and Functions
Since heavy-gauge pipes and light gauge pipes hold different kinds of thicknesses, sizes, and types, they serve different functions and purposes.
Heavy gauge pipes are commonly chosen in applications and construction where pressure is very high. For instance, heavy-gauge galvanized pipes are used for water supply pipes in construction since this setting requires high pressure. Its zinc barrier also helps in preventing the buildup of any deposits that can possibly clog water lines. On the other hand, light gauge pipes can be utilized for doors, window hoods, finials, and cresting.
As for heavy gauge black iron pipes, these are what is commonly used for fire alarm systems and to transport gas for both commercial and residential use. Light gauge black iron pipes are used for playground equipment such as slides and swings, and other structures that need supportive elements.
Key Takeaway
There are many types of pipes that are utilized for building and construction. Two of the most common are heavy gauge and light gauge pipes. There is a distinct difference of heavy gauge and light gauge pipes. Because both of these differ in thickness, they are used for different types of applications. Heavy gauge pipes are commonly used in high pressured and large flow applications. On the other hand, light gauge pipes are used in applications that don’t exceed the pressured of 0.15N/mm2 or in light-framed structures.
