EN10253-1 Pipe Fitting Elbow S235 S265 Butt Weld Carbon Steel 5D 180 Degree Pipe

Chemical Analysis and Testing of EN10253-1 Butt Welding Fittings:

The manufacturer is required to conduct chemical analysis of each cast, as well as perform yield strength, tensile strength, and hardness tests. The tensile test must comply with EN 10002-1 standards, with the test piece extracted longitudinally without flattening. For fittings with a diameter equal to or less than 114.3 mm, a Brinell hardness test following EN 10003-1 guidelines may be conducted instead of a tensile test. Both the chemical composition and mechanical properties test results must meet the specifications outlined in EN 10253-1.

Chemical Requirements S235 and S265:

Chemical requirements of steel grade S235 are as follows:

• Carbon (C): Maximum 0.16%
• Silicon (Si): Maximum 0.35%
• Manganese (Mn): Maximum 1.2%
• Sulphur (S): Maximum 0.025%
• Phosphorus (P): Maximum 0.030%

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:

• Carbon (C): Maximum 0.20%
• Silicon (Si): Maximum 0.40%
• Manganese (Mn): Maximum 1.40%
• Sulphur (S): Maximum 0.025%
• Phosphorus (P): Maximum 0.030%

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.

Wastewater Treatment Plants: In wastewater treatment plants, EN10253-1 Carbon Steel 5D 180 Degree Elbows are used to reverse the direction of the flow, redirecting the treated water or sludge to the desired location for further processing or disposal. They are often employed in applications such as sewage treatment, sludge handling, and water reclamation processes.

Chemical Plants: Chemical processing facilities often utilize EN10253-1 Carbon Steel 5D 180 Degree Elbows to change the flow direction in pipelines handling different chemicals or fluids. These elbows allow for efficient routing of pipelines, enabling the transfer of materials between different processing units or storage tanks.

Power Generation Facilities: Power plants, including thermal power plants and nuclear power plants, utilize EN10253-1 Carbon Steel 5D 180 Degree Elbows in their piping systems. These elbows help redirect the flow of steam, water, or other fluids within the power generation processes, facilitating efficient energy production.

Tight Space Installations: In applications where space is limited, such as in HVAC (heating, ventilation, and air conditioning) systems, confined areas, or retrofit projects, EN10253-1 Carbon Steel 5D 180 Degree Elbows are used to navigate the piping through tight spaces or obstacles. They allow for a significant directional change within a relatively small area, optimizing the layout of the piping system.

Plumbing Systems: In residential, commercial, and industrial plumbing systems, EN10253-1 Carbon Steel 5D 180 Degree Elbows can be used to redirect water or fluid flow to accommodate specific building layouts or plumbing requirements. They can be employed in water supply lines, drainage systems, or irrigation systems to change the direction of the flow as needed.
