Forged ASTM A266 Gr.2 Carbon Steel support Plate / Baffle Plate for Pressure Vessel and Heat Exchanger


ASTM A266 Grade 2 is a carbon steel material that is commonly used for pressure vessel components such as baffle plates. A baffle plate is a plate designed to restrain or regulate the flow of fluid, and then enhance heat transfer. Baffle plates made from ASTM A266 Grade 2 have good strength and toughness properties, making them suitable for use in high-pressure and high-temperature applications. However, it is important to ensure that the specific requirements of the application are met, and that the baffle plate is properly designed and fabricated to meet applicable standards and codes.


In order to offer a clear price of a baffle plate, you will typically need to provide the following information:
1. Material: The type of material you require for the baffle plate, such as carbon steel, stainless steel, or other alloys.
2. Dimensions: The size and shape of the baffle plate, including its thickness, width, and length. (as drawing required)
3. Quantity: The number of baffle plates
4. Application: The specific application or equipment in which the baffle plate will be used.
5. Additional requirements: Any additional requirements or specifications, such as surface finish, tolerances, or testing.


There are several types of baffle plates, including:
1. Segmental baffle plates: These are flat plates with a curved or angled edge that are used to direct fluid flow in a specific direction.
2. Disc and doughnut baffle plates: These are circular plates with a hole in the center that are used to create a swirling motion in the fluid.
3. Orifice baffle plates: These are plates with an orifice or small hole that are used to control the flow rate of the fluid.
4. Perforated baffle plates: These are plates with small holes or perforations that are used to distribute fluid evenly across the heat exchanger.
5. Rod baffle plates: These are thin rods that are placed perpendicular to the fluid flow to create turbulence and improve heat transfer.
