EN10253-2 Butt Welding Elbow

EN10253-2 standard is one of the standards developed by the European Committee for Standardization (CEN), which specifies the dimensional and material requirements for seamless and welded steel pipes and fittings. This standard is mainly applicable to seamless and welded steel pipes and fittings used in pressure applications, including elbows, tees, eccentric offsets, and pipe connections.

Butt welding elbow is the most widely used type of pipe fitting in pipeline systems. It plays a role in changing the direction of the pipeline in the pipeline system. EN10253-2 butt welding elbow can be divided into 45 degree elbow, 90 degree elbow and 180 degree elbow according to the angle; it can be divided into 2D elbow, 3D elbow and 5D elbow according to the bending radius.

Impact Properties

EN10253-2 butt welding elbows are mainly used in industrial piping systems, especially in those requiring certain pressure and temperature resistance. For example, the petroleum and natural gas industry, chemical industry, pharmaceutical industry, food processing industry, etc. In these fields, butt welding elbows are widely used for the connection and branching of pipelines to achieve the transmission and control of fluids (such as gases and liquids). In addition, EN10253-2 butt welding elbows are also commonly used in high-tech fields such as nuclear energy, aerospace, and marine. In these situations, the high quality and reliability of butt welding elbows are crucial to ensure the safety and performance of the entire system. In general, EN10253-2 butt welding elbows have a wide range of applications in various industrial piping systems that require pressure resistance, and their quality and performance play a vital role in the safety and reliability of the entire system.
