ANSI/ASME B16.5 Class 2500 Carbon Steel Weld Neck Flanges:

The ANSI/ASME B16.5 Class 2500 Carbon Steel Weld Neck Flanges are designed to withstand extremely high-pressure applications. Here are some details about these flanges:

Pressure Rating: The Class 2500 designation indicates that these flanges are capable of withstanding pressures up to 2500 pounds per square inch (PSI). They are specifically designed for high-pressure piping systems.

Material: These flanges are made from carbon steel, which is known for its strength and durability. Carbon steel offers excellent resistance to corrosion and can handle high-temperature and high-pressure conditions effectively.

Weld Neck Design: The flanges feature a weld neck design, which provides a strong and secure connection between pipes or fittings. The long tapered hub of the flange allows for smooth flow transition and reduces turbulence in the piping system.

Standard Dimensions: The ANSI/ASME B16.5 standard specifies the dimensions and tolerances for these flanges. The flanges are available in various sizes, ranging from 1/2" to 24", to accommodate different pipe diameters.

Face Type: The flanges have a raised face (RF) surface finish, which ensures a tight seal when connected to mating flanges. The raised face also helps to prevent leakage and provides additional structural strength.

Bolt Holes and Bolting: The flanges have bolt holes that are drilled following specific patterns, allowing for easy alignment and assembly. The number and size of bolt holes depend on the flange size. These flanges require high-strength bolts for proper installation and pressure containment.

Application: ANSI/ASME B16.5 Class 2500 Carbon Steel Weld Neck Flanges are commonly used in industries such as oil and gas, petrochemical, power generation, and chemical processing, where high-pressure and high-temperature conditions are present.

Advantages of ANSI/ASME B16.5 Class 2500 Carbon Steel Weld Neck Flanges:

The ANSI/ASME B16.5 Class 2500 Carbon Steel Weld Neck Flanges offer several advantages due to their design and material characteristics. Some of the key advantages include:

High Pressure Rating: Class 2500 flanges are designed to withstand extremely high pressure, making them suitable for applications where the system operates at elevated pressures. This high pressure rating ensures the integrity and safety of the piping system in demanding industrial environments.

Enhanced Strength: Carbon steel is known for its high strength and toughness, and when applied to weld neck flanges, it provides exceptional structural integrity. This makes Class 2500 carbon steel weld neck flanges ideal for critical applications where strong and reliable connections are essential.

Resistance to Corrosion: Carbon steel exhibits good resistance to corrosion in various industrial environments, particularly when proper surface treatments and coatings are applied. This corrosion resistance is advantageous in applications where the flanges are exposed to corrosive substances or harsh operating conditions.

Reliable Sealing Performance: Weld neck flanges provide a strong and leak-resistant connection between pipes or valves. The welding neck design helps reduce stress concentrations and provides a smooth transition from the flange to the pipe, ensuring a reliable seal under high-pressure conditions.

Wide Application Range: Class 2500 carbon steel weld neck flanges find use in a diverse range of industries, including oil and gas, petrochemical, power generation, chemical processing, and more. Their high pressure rating and robust construction make them suitable for critical systems in these industries.

Compatibility: Carbon steel weld neck flanges are compatible with a wide range of piping materials and are well-suited for connecting pipes made of carbon steel, stainless steel, and other common piping materials.

Grades of Carbon Steel Flanges:

American standard carbon steel flanges are flanges made of carbon steel and are widely used in industries such as petroleum, chemical, natural gas, shipbuilding, construction, and water conservancy. Its carbon steel grades are usually divided into the following parts:

1.Q235: Q235 is a commonly used carbon structural steel grade specified in the Chinese national standard GB/T 700. It is often used in general engineering structures and manufacturing industries. In carbon steel flanges, Q235 material is commonly used for pipeline systems operating at low pressure, low temperature, and non-critical stress environments.

2.A105: A105 is a carbon steel material specified in the American ASTM standard, complying with ASTM A105/A105M requirements. A105 material has good weldability and mechanical properties, making it suitable for use in a wide temperature range from low to high temperatures. It is commonly used for pipeline systems and valve connections under high temperature and high-pressure conditions.

3.A350 LF2: A350 LF2 is also a carbon steel material specified in the ASTM standard, complying with ASTM A350/A350M requirements. LF2 indicates low-temperature service, and this material has good low-temperature toughness and crack resistance. It is commonly used for pipeline systems and valve connections under low-temperature conditions.

4.A694 F42/F52/F60/F65/F70: These material grades are specified in the ASTM A694 standard for carbon steel materials used in high-strength, low-temperature, or normal temperature high-pressure pipeline systems and valve connections. Different grades of materials have different strengths and corrosion resistance properties, suitable for various working conditions.

5.ASTM A181 Gr.1/Gr.2: These carbon steel flange material grades are suitable for pressure vessels, valves, and pipeline fittings under low pressure and low temperature conditions. They have good machinability and mechanical performance.

6.ASTM A516 Gr.70: Gr.70 is a commonly used medium carbon steel grade, known for its good weldability and machinability, suitable for manufacturing flanges and pipe fittings, among others.

7.A216 WCB: A216 WCB is a carbon steel casting material specified in the American ASTM standard, complying with ASTM A216/A216M requirements. WCB stands for cast carbon steel, and it is commonly used for carbon steel flanges that require casting in general engineering structures and manufacturing industries.

These material grades mentioned above are only a part of the commonly used ones, and there are other material grades in practical applications. When selecting the material grade for carbon steel flanges, it is necessary to consider engineering requirements, temperature, pressure, medium, and the requirements of relevant standards to ensure that the flange material meets the corresponding performance and safety requirements.
