The minimum tensile strength for A53 Grade B pipes is 60,000 psi. The tensile strength of A53 pipes should be a minimum of 48,000 psi for Grade A. We will now explore the mechanical and physical properties of A53 and A106 pipes. However, there are a few differences, like the presence of silicon in A106 pipes and its absence in A53 pipes.Īdditionally, they also contain different amounts of the following components:Ī53 vs. The chemical composition of A53 and A106 pipes are mostly similar. Weight per foot: Between - 3.5% and 10% against specification.The thickness of the wall: The nominal pipe’s size (minus) 12.5%.Now, let’s check out the tolerance for A106 pipes: The thickness of the wall: At least the minimum size of the pipe (minus) 12.5%.The manufacturing tolerances for A53 pipes are as follows: They offer the same level of performance and durability but for a lower price.Īs a result, you can expect more returns from your investment. Galvanized pipes are more affordable than copper pipes. Therefore, you don’t have to worry about anything, even in stressful working conditions. Additionally, the protective layer of zinc provided during galvanization makes it more sturdy. You can use them for different hazardous environments and fluids that cause corrosion.Īs a result, your pipes last for a longer pipe compared to metals like iron or standard steel. Galvanization offers steel pipes protection from rust and corrosion. What are the benefits of galvanized A53 and A106 pipes? Protection from Corrosion Generally, producers use a zinc coating of 1.6 to 1.8 oz per square foot. Manufacturers use the process to apply a protective layer of zinc both on the outer and inner sides of the pipe. Galvanized pipes go through a process called hot-dip galvanization. Many industries use galvanized A53 and A106 pipes. What about the composition of A106 Grade A and B pipes? Gradeīenefits of Galvanized ASTM A53 and A106 Pipes The same applies to A106 Grade A and B pipes.īelow is a chart comparing both grades for A53 pipes: Type Cold Drawn pipes Chemical DifferencesĪ53 Grade A and B pipes share almost the same chemical composition except for a few metals. They are made only with a seamless execution method. However, they treat cold-drawn pipes after they finish the cold draw pass. They also use heat treatment after the pipe is hot-finished. Additionally, they may also make use of refining or degassing.Īdditionally, producers use steel casts or strand casts. Manufacturers melt raw steel using a furnace, just like A53 pipes. A106 PipesĪ106 Grade B is the most common grade used in industries. Manufacturers utilize the extrusion method to produce both grades of the pipes. They are also available in Grade A and B. However, Grade B steel pipes undergo a heat treatment of at least 540 degrees C post welding. They are produced using a continuous coil and rely on electrically-generated heat to seal the longitudinal joints. Type E steel pipes, for instance, come in Grade A and B. However, you cannot buy Grade B pipes for type F A53 as there are no specifications.Īll A53 pipes use raw steel produced in the following ways: Additionally, the manufacturers seal the longitudinal joint using forge welding. Type F Grade A steel pipes rely on a continuous coil for production. Let’s explore them below: Manufacturing Process A53 Pipes Grade A and B steel pipes share a few differences in manufacturing and composition. Differences Between Grade A And Grade B Steel Pipes Let’s start by looking at the difference between Grade A and Grade B pipes. High-temperature and high-pressure applications in oil, power, and stressful industriesĬhromium 0.4, Carbon 0.25 - 0.3, Manganese 0.95 - 1.2, Sulfur 0.45Ĭhromium 0.4, Carbon 0.25 - 0.3, Manganese 0.27 - 1.06, Silicon 0.1īetween - 3.5% and 10% against specification Specifications for standard carbon and seamless steel pipe Specifications for zinc-coated, welded, and seamless steel pipes We will go into details such as chemical composition, physical properties, tolerances of the pipes, and more. In this blog, we will explore the differences between A53 and A106 pipes. However, only a single type of ASTM A106 pipe exists, unlike A53. Each one again has different properties.Īdditionally, A106 pipes are also available in Grade A and B. They are also classified into two grades, Grade A and B. However, these differences become crucial when sourcing for your business or operations.įor example, A53 pipes come in three types, F, E, and S. They are helpful for various purposes like transporting hot steam or fluids under high pressure.Ī53 and A106 share a few fundamental differences that you might overlook at first glance. ASTM A53 (or ASME SA 53) and A106 are the two most popular steel types used in different industries.
