Determination Sheet and Data Sheet of Shell and tube Heat exchanger

 

Shell and Tube Heat Exchanger "Determination sheet"

A Shell and Tube Heat Exchanger (STHE) determination sheet is a document used in the design and selection process of a shell and tube heat exchanger. This sheet typically includes various parameters and calculations necessary to determine the specifications of the heat exchanger for a particular application. These parameters may include:

1. Heat duty: The amount of heat transfer required between the fluid streams.

2. Inlet and outlet temperatures of both hot and cold fluid streams.

3. Flow rates of hot and cold fluids.

4. Physical properties of the fluids such as density, specific heat, viscosity, and thermal conductivity.

5. Design pressure and temperature requirements.

6. Material of construction for the shell, tubes, and tube sheets.

7. Tube diameter, length, and layout.

8. Number of tube passes and baffles.

9. Fouling factors.

10.Allowable pressure drop.

11.Type of tube sheet construction (floating or fixed).

12.Type of tube side and shell side fluid passes (counter flow, parallel flow, or cross flow).

13.Requirements for insulation and corrosion protection.

The determination sheet serves as a guide for engineers to properly size and select the appropriate shell and tube heat exchanger for a specific process or application, ensuring efficient heat transfer while meeting the required design parameters and safety standards.

Shell and tube heat exchanger Data Sheet:-

A data sheet for a shell and tube heat exchanger may contain similar information to a determination sheet, but it's typically more condensed and focused on the specifications of a particular model or design rather than the calculation and selection process.

A data sheet for a shell and tube heat exchanger usually includes:

1. Model number or identifier.
2. Physical dimensions and weight.
3. Material of construction.
4. Maximum allowable working pressure and temperature.
5. Flow rates and connection sizes.
6. Heat transfer area.
7. Design standards compliance (e.g., ASME, TEMA).
8. Optional features or accessories.
9. Manufacturer's information and contact details.

While a determination sheet is used during the design and selection process to calculate parameters and make decisions, a data sheet serves as a reference for the specifications and features of a specific heat exchanger model once it has been selected for a project.
