What is din 2440 threaded steel tubes?
DIN 2440 is a specification for carbon steel tubes. The round pipes of this specification are the most commonly used compared to the other shapes available. The DIN 2440 Threaded Steel Tubes come with internal threads which helps in easy, quick and leakage-free connections. The Threaded Steel Tubes DIN 2440 are basically used in areas where welding is not possible. The presence of internal threads in the EN 10255-M DIN 2440 Tube helps with easy mounting and the piping systems can be connected safely without causing any accidents. The DIN 2440 Grade St 33-2 Round Pipes are found in oil and gas industries.
They come with good hardness properties. These tubes are available in different forms like annealed, polished, pickled, etc. They are used for a wide range of high temperature and high pressure applications like heat exchanger, boiler components, fluid transfer lines, and so on. The tubes acquire its properties due to the chemical composition, which includes elements like carbon, chromium, silicon, manganese, molybdenum, etc. They come with min tensile strength of 310 MPa, and min yield strength of 185 MPa. These pipes have greater load bearing capacity and they do not have the risk of getting corroded due to grain sensitization. The properties of these pipes can be enhanced through carburization or sensitization- it ensures to increase the hardness of the tubes without making them brittle.
