We are professional Baffle Plate SA387 GR.11 CL.2 for Heat Exchanger,BAFFLE PLATE,TUBE SUPPORT PLATE manufacturer and exporter in china.
What is Baffle plate?
Baffle plate is widely used in shell and tube heat exchanger, boiler, pressure vessel, steam turbine, large central air Conditioning, etc. The baffle sheet is mainly used for chemical containers, such as shell and tube heat exchanger, Boiler, pressure vessel, condenser, central air conditioning, evaporator, water desalination with the function of Supporting the tube bundle and improving heating efficiency.
The material of metal makes it not only has the very strong rigidity, and has a great deal of heat conduction performance.
Application of baffle plate: Heat exchanger, boiler, pressure vessel, steam burbine, air conditioning., etc
Function of baffle: Support and fix the tube and shell, heat conductive, corrosive resistant, high pressure
Baffle Plate SA387 GR.11
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.
ASTM A387 is a standard specification for pressure vessel plates, alloy steel, chromium-molybdenum. This type of steel is used for high-temperature service.
SA387 Gr. 11 Cl. 2 is a chromium-molybdenum alloy steel that contains approximately 0.5% chromium and 1% molybdenum. This composition provides enhanced strength, improved resistance to thermal fatigue, and high creep strength at elevated temperatures, making it suitable for high-temperature and high-pressure applications.
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.
