copy of ASTM LR 3D 90° seamless elbow P265GH SCH40 219.1mm x 6.3mm

Description:

The ASTM LR 3D 90° seamless bend in P265GH steel, SCH40, is a pipe fitting designed to change the direction of flow at a 90-degree angle. The term "LR" (Long Radius) indicates a bending radius equal to 1.5 times the nominal pipe diameter, while "3D" means that the bending radius is three times the nominal diameter.

The main characteristics of this product are :

• Material: P265GH carbon steel, EN 10216-2 compliant.
• Angle: 90 degrees.
• Bending radius: 3D (three times the nominal diameter).
• Type: Seamless.
• Series: (equivalent to SCH40).
• Finish: Black

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

The ASTM LR 3D 90° seamless elbow in P265GH steel, Series E (SCH40), is an essential component in industrial piping systems. Here are further details on its technical features:

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

Pressure rating: Series E (SCH40) 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: Elbows are available in a range of nominal diameters (DN), for example, from DN10 to DN600, with wall thicknesses varying according to diameter and series selected.

Radius of curvature: The term "3D" indicates that the radius of curvature is equal to three times the nominal pipe diameter, offering a smoother transition for the fluid flow.

Applications: This type of elbow 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 elbow in P265GH Schedule 40 steel features the following technical characteristics:

Temperature and pressure :

Service temperature: P265GH steel is designed for high-temperature applications, with notable creep resistance at 425°C.

Pressure rating: SCH40 corresponds to a specific wall thickness which influences 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 elbows 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 elbow and the specific requirements of the application. It is essential to refer to manufacturers' standards or data sheets for detailed information.

Mechanical properties ensure that the P265GH elbow 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.

For precise and detailed information, we recommend consulting EN 10253-2 and EN 10028-2, as well as the manufacturers' technical data sheets.
