A387 Grade 11 Class 2N Chemical Composition and Mechanical Properties

A387 Grade 11 Class 2N is a chromium-molybdenum alloy steel widely used in pressure vessels and heat exchanger shells. The "N" indicates that the material has undergone normalization, a heat treatment process that enhances its mechanical properties, making it suitable for applications requiring durability and resistance to high temperatures and corrosion.

Chemical Composition of A387 Grade 11 Class 2N

The chromium and molybdenum content provides excellent resistance to oxidation, hydrogen attack, and other high-temperature corrosive environments.

Mechanical Properties of A387 Grade 11 Class 2N

With its superior mechanical properties, A387 Grade 11 Class 2N is ideal for use in heat exchanger shells that operate under extreme pressures and temperatures.

SA213 T11 Mechanical Properties

SA213 T11 is a ferritic alloy steel used for seamless tubes in heat exchangers and boilers due to its outstanding performance in high-temperature and high-pressure environments. Its chemical composition and mechanical properties make it a perfect match for A387 Grade 11 Class 2N shells.

Mechanical Properties of SA213 T11

The combination of strength, ductility, and resistance to high-temperature oxidation makes SA213 T11 tubes ideal for efficient heat transfer in demanding applications.

Shell and Tube Heat Exchanger Types

Shell and tube heat exchangers are one of the most versatile and widely used heat exchange systems in industrial applications. Their robust design and high efficiency make them suitable for handling various fluids, including gases, steam, and liquids. The A387 Grade 11 Class 2N Shell and SA213 T11 Tube Heat Exchanger is a prime example of this technology.

Types of Shell and Tube Heat Exchangers

1. Fixed Tube Sheet Heat Exchangers:

   • Economical design with fixed tube sheets welded to the shell.
   • Suitable for applications where thermal expansion is minimal.

2. Floating Head Heat Exchangers:

   • Allow for thermal expansion and contraction of tubes.
   • Ideal for high-temperature applications with significant thermal stress.

3. U-Tube Heat Exchangers:

   • Compact design with U-shaped tubes, reducing stress caused by temperature differences.
   • Easy to clean and maintain.

4. Double-Pass Heat Exchangers:

   • Increase heat transfer efficiency by allowing fluid to pass through the system twice.
   • Suitable for applications requiring compact designs.

At Yuhong Holding Group, we manufacture heat exchangers using the best materials and designs to optimize performance and durability.
