ASTM A182 F304, 304L, SUS304 Stainless Steel Tubesheet For Heat Exchanger

ASTM A182 F304, 304L, SUS304 Stainless Steel Tubesheet For Heat Exchanger

The composition of F304 and 304 is basically the same, F refers to the difference between the forging and the forming process, F304 adopts forging processing, 304 can be processed by rolling, cold drawing and other ways; F304 is used to manufacture pressure vessels, flanges and other parts with high performance requirements, while 304 is relatively loose.

A182 is the standard number (ASTM A182/A182M), corresponding to ASME standard SA182/SA182-M, high temperature forged or rolled alloy steel pipe flanges, forged pipe fittings, valves and parts Technical specifications.

304 stainless steel is a common material in stainless steel, with a density of 7.93 g/cm³, also known as 18/8 stainless steel in the industry. High temperature resistance 800℃, with good processing performance, high toughness characteristics, widely used in industrial and furniture decoration industry and food and medical industry.

Among the common expression methods on the market are 06Cr19Ni10 and SUS304, of which 06Cr19Ni10 generally indicates national standard production, 304 generally indicates ASTM standard production, and SUS304 indicates Japanese standard production.

Structure and performance characteristics of tube heat exchanger

Shell-and-tube heat exchanger, also known as tubular heat exchanger, is a general standard heat exchange equipment. It has the advantages of simple structure, robustness and durability, low cost, wide range of materials, convenient cleaning, strong adaptability, etc., and is the most widely used and occupies a dominant position in heat exchange equipment. Shell-and-tube heat exchangers are divided into the following types according to their structural characteristics.

The fixed tube-plate heat exchanger consists of a shell, a tube bundle, a head, a tube plate, a baffle plate, a nozzle and other components. The structural feature is that two tubesheet are welded to both ends of the shell, and both ends of the tube bundle are fixed on the tubesheet. The whole heat exchanger is divided into two parts: the channel in the heat exchange tube and its two ends are called the pipe; The channel outside the heat exchange tube and its connecting point are called the shell path. The cold and hot fluids flow continuously in the pipe path and the shell path respectively. The fluid flowing through the pipe path is called the pipe (pipe path) fluid, and the fluid flowing through the shell path is called the shell (shell path) fluid.

Main characteristics of Tubesheet

1. Strong bearing capacity, good stability, good seismic and deformation resistance.
2. Various materials and varieties, different materials and specifications can be selected according to needs.
3. Easy to install, easy to use, wide adaptability.

Apllication:

1.Tubular heat exchangers

2.Pressure vessels

3.boilers, condensers

4.Central air conditioning

5.Evaporators

6.Seawater desalination
