EN10253-1 Pipe Fitting Elbow Carbon Steel S235 S265 5D Radius 90 Degree Elbow for Industrial Piping Systems
Product Introduction of EN10253-1 90 Degree 5D Radius Elbows:
EN 10253-1 standard covers factory-wrought carbon steel butt welding pipe fittings, including a variety of shapes such as elbows, return bends, concentric and eccentric reducers, equal and reducing tees, dished ends, and caps. These fittings are supplied without specific inspection requirements. The EN 10253-1 standard is derived from the obsolete DIN pipe fitting standard series.
Manufacturers have the flexibility to produce these butt welding pipe fittings using either hot or cold deformation processes from raw materials such as seamless tubes, welded tubes, plates, forgings, and bars. The choice regarding the manufacturing process for the base material is at the discretion of the manufacturer, allowing for customization based on specific requirements.
Overall, EN 10253-1 sets the specifications and guidelines for the production of carbon steel butt welding pipe fittings, ensuring quality and compatibility within various industrial applications.
Chemical Requirements S235 and S265:
Chemical requirements of steel grade S235 are as follows:
Elements not listed in the table should not be deliberately added to the steel without the purchaser's agreement, except for deoxidizing elements. However, residual elements may be acceptable as long as they do not negatively impact the mechanical properties and suitability of the steel.
Chemical requirements of steel grade S265 are as follows:
According to the standard, elements not included in this table should not be intentionally added to the steel without the agreement of the purchaser, except for elements used for deoxidation. However, residual elements may be tolerated, provided that they do not adversely affect the mechanical properties and applicability of the steel.

Applications of 5D Radius 90 Degree Elbows:
5D radius 90-degree elbows, also known as long radius 90-degree elbows, find applications in various industries and piping systems where a gradual change in direction and reduced pressure drop are desired.
Oil and Gas Industry: 5D radius 90-degree elbows are widely used in oil and gas pipelines, both onshore and offshore. They facilitate smooth directional changes and help maintain the flow efficiency of petroleum products, natural gas, and other fluids throughout the pipeline network.
Chemical Processing: In chemical plants and refineries, 5D radius 90-degree elbows are employed in piping systems that transport various chemicals, acids, solvents, and corrosive substances. The larger radius of these elbows minimizes pressure drop, reduces turbulence, and ensures the integrity of the process.
Power Generation: Power plants, including thermal power plants and nuclear power plants, utilize 5D radius 90-degree elbows in their piping systems. They are commonly used in applications such as condenser water systems, cooling water circuits, and steam distribution, where smooth flow transitions and minimal pressure loss are critical.
HVAC Systems: Heating, ventilation, and air conditioning (HVAC) systems often incorporate 5D radius 90-degree elbows in ductwork installations. They facilitate efficient airflow distribution, reduce pressure drop, and minimize noise and turbulence in the system.
Water and Wastewater Treatment: 5D radius 90-degree elbows are commonly used in water and wastewater treatment plants. They assist in directing the flow of water, chemicals, and sludge, ensuring efficient treatment processes, reducing energy consumption, and minimizing pressure losses.
Food and Beverage Industry: In food processing plants and breweries, 5D radius 90-degree elbows are employed to maintain hygienic conditions in the piping systems. They facilitate smooth flow transitions, minimize pressure drop, and ensure the integrity and quality of the processed food and beverages.
