The main features of this product are

• Material: P265GH carbon steel, EN 10216-2 compliant.
• Type: Seamless.
• Series: E (equivalent to SCH20).
• Finish: Black
• Ends: Butt-weld (BW), facilitating seamless connection in piping systems

It's important to select the right dimensions for your specific project requirements.

The P265GH steel E-Series (SCH20) Eccentric Seamless Reducer is an essential component in industrial piping systems. Here are further details on its technical features:

Manufacturing standards: This Eccentric Reducer complies with EN 10216-2 standards for seamless steel pipes and ASTM specifications for pipe fittings.

Pressure rating: Series E (SCH20) corresponds to a specific wall thickness, influencing the pressure rating the elbow can withstand. It is essential to consult the correspondence tables to determine the maximum pressure according to nominal diameter and wall thickness.

Available sizes: Eccentric Reducers are available in a range of nominal diameters (DN), for example, from DN10 to DN600, with wall thicknesses varying according to the diameter and series selected.

Applications: This type of Eccentric Reduction is commonly used in the oil, gas, chemical and power industries, where high-pressure and high-temperature conditions are present.

The ASTM LR 3D 90° Seamless Eccentric Reduction in P265GH E-series steel (SCH20) features the following technical specifications:

Temperature and pressure :

Operating temperature: P265GH steel is designed for high-temperature applications, with notable creep resistance at 400°C.

Pressure rating: Series E (SCH20) corresponds to a specific wall thickness influencing the pressure rating. Precise values depend on the nominal diameter and wall thickness of the elbow. It is recommended to consult the relevant standards or the manufacturer's specifications for exact data.

Dimensional tolerances :

The dimensional tolerances of P265GH steel eccentric reducers are defined by EN 10253-2 and EN 10028-2. These standards specify permissible tolerances for dimensions such as outside diameter, wall thickness, bending radius and length. Precise values vary according to the nominal dimensions of the eccentric reducers and the specific requirements of the application. It is essential to refer to manufacturers' standards or data sheets for detailed information.

Mechanical properties :

Minimum yield strength: 265 MPa for thicknesses up to 16 mm.

Tensile strength: 410 to 530 MPa.

Elongation at break: 22% minimum.

These properties ensure that P265GH Eccentric Reduction is suitable for pressure and high-temperature applications, offering a combination of mechanical strength and ductility.

Chemical composition :

P265GH steel is an unalloyed steel with the following chemical composition:

Carbon (C): ≤ 0.20

Silicon (Si): ≤ 0.40

Manganese (Mn): 0.80 to 1.40

Phosphorus (P): ≤ 0.025

Sulfur (S): ≤ 0.010 %

Total aluminum (Al): ≥ 0,020 %

Nitrogen (N): ≤ 0.012 %

This composition gives P265GH steel good weldability and mechanical properties suitable for high-temperature and pressure applications.
