ASTM A53 seamless and welded steel pipe is a general, all-purpose pipe. Designed for coiling, bending, and flanging, A53 carbon steel pipe is suitable for welding.
ASTM A53 seamless and welded steel pipe is a general, all-purpose pipe. Designed for coiling, bending, and flanging, A53 carbon steel pipe is suitable for welding. The grades denote certain chemical and mechanical properties and should be noted in the selection. A53 pipe is intended for mechanical and pressure applications and is also acceptable for ordinary uses in steam, water, gas and air lines, Low pressure systems, Structural applications, Mechanical components, Bollards, Casing, generator plants, refineries, compressor stations, natural gas transmission, and steam conduction.
MANUFACTURING PROCESS
The manufacturing process differs depending on the particular type and grade of ASTM A53 that it is. The steel for both seamless and welded pipe shall be made by one or more of the following processes: open-hearth, electric furnace, or basic oxygen. The weld seam of the electric-resistance welded pipe in Grade B shall be heat treated after welding. Below are the different types available in ASTM A53 pipe.
CORROSION RESISTANCE
Carbon steel pipes can be resistant to corrosion due to the addition of lacquer coating, hot-dipped galvanizing, or zinc coating. This allows builders to use smaller, thinner pipes, even in environments that are acidic or extremely corrosive.
