EN10253-1 S235 S265 3D Radius Carbon Steel/ Alloy Steel 180 Degree Pipe Fitting Black Painting For Piping System

Testing Requirements of EN10253-1 Butt Weld Fittings:

1. Chemical Analysis:

   • The manufacturer must conduct a chemical analysis of each cast to verify that the material composition meets the requirements specified in EN10253-1.

2. Mechanical Testing:

   • Yield Strength Test: This test measures the stress at which a material begins to deform plastically. It is important for determining the point at which a material transitions from elastic to plastic behavior under tensile loading.
   • Tensile Strength Test: This test measures the maximum stress a material can withstand before it breaks under tension. The test is carried out in accordance with EN 10002-1, which specifies the testing procedures for tensile testing.
   • Hardness Test: The hardness test measures the resistance of a material to deformation. Brinell hardness testing, as per EN 10003-1, is conducted on fittings with a diameter equal to or less than 114.3 mm in place of a tensile test.

3. Testing Procedures:

   • The tensile test should be conducted in the longitudinal direction without flattening the test piece to accurately assess the material's mechanical properties.
   • For fittings with a diameter equal to or less than 114.3 mm, a Brinell hardness test is performed in place of a tensile test to evaluate the material's hardness.

4. Compliance Requirements:

   • Both the chemical composition analysis and mechanical testing results must conform to the standards outlined in EN10253-1 to ensure the fittings meet the required quality and performance criteria.

By adhering to these testing requirements and ensuring compliance with EN10253-1 standards, manufacturers can verify the quality and integrity of their butt-weld fittings to meet industry regulations and specifications.

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.

Applications of EN10253-1 Carbon Steel 3D 180 Degree Elbows:

Wastewater Treatment Plants: In wastewater treatment plants, EN10253-1 Carbon Steel 3D 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 3D 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 3D 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 3D 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 3D 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.
