HEAT EXCHANGER PARTS PRESSURE VESSEL BAFFLE PLATE SA387 GR.11 CL.2 A36
A baffle plate made from SA387 Gr. 11 Cl. 2 refers to a component used in pressure vessels, heat exchangers, or other equipment that requires specific material properties for handling high pressure and temperature. Here's a breakdown of the relevant terms:
SA387 Gr. 11 Cl. 2: This is a designation for a specific type of steel used in pressure vessel construction.
ASTM A387 is a standard specification for pressure vessel plates, alloy steel, chromium-molybdenum. This type of steel is used for high-temperature service.
Gr. 11: Refers to Grade 11, which is an alloy steel made with
chromium and molybdenum. It provides excellent resistance to heat
and corrosion, making it ideal for high-temperature, high-pressure
applications.
Cl. 2: Refers to Class 2, which indicates a specific heat treatment
process for the steel, ensuring it has the required strength and
durability for demanding service conditions.
Baffle Plate: A baffle plate is used to direct the flow of fluids in heat exchangers or other equipment, optimizing the heat transfer process and enhancing performance. It also helps to maintain proper fluid distribution and minimize vibration.
Here's an overview of the grade table for ASTM A387:
| Grade | Nominal Composition (Cr-Mo) | Tensile Strength (MPa) | Yield Strength (MPa) | Application |
|---|---|---|---|---|
| Grade 2 | 0.5% Cr, 0.5% Mo | 415-585 | ≥ 205 | Moderate-temperature environments. |
| Grade 5 | 1.0% Cr, 0.5% Mo | 415-585 | ≥ 205 | Medium-temperature environments. |
| Grade 9 | 2.25% Cr, 1.0% Mo | 515-690 | ≥ 310 | High-temperature environments. |
| Grade 11 | 1.25% Cr, 0.5% Mo | 515-690 | ≥ 310 | High-temperature service. |
| Grade 12 | 1.0% Cr, 1.0% Mo | 515-690 | ≥ 310 | Elevated-temperature environments. |
| Grade 22 | 2.25% Cr, 1.0% Mo | 515-690 | ≥ 310 | High-temperature, creep-resistant. |
| Grade 91 | 9.0% Cr, 1.0% Mo, V, Nb | 585-760 | ≥ 415 | Very high-temperature applications. |
