ASTM P265GH Series E / SCH20 seamless concentric reducer 139,7mm x 88,9mm

Description:

The ASTM seamless P265GH steel concentric reducer, Series E (SCH20), 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, resistant to high pressures and temperatures, in compliance with ASTM A234 WPB / ASME SA234 specifications.
• Type: seamless concentric reduction.
• Series: E (equivalent to SCH20).
• Finish: Black

It is important to select the appropriate dimensions according to the specific requirements of your project.

The ASTM P265GH SCH20 seamless concentric reducer is an essential component in industrial piping systems. Here are further details of its technical features:

Manufacturing standards: This concentric reducer complies with EN 10216-2 standards for seamless steel tubes 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: Concentric reductions 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 concentric reducer is commonly used in the oil, gas, chemical and power industries, where high-pressure and high-temperature conditions are present.

The P265GH Series E (SCH20) seamless steel concentric reducer features the following technical characteristics:

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 concentric 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 concentric reductions 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 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.
