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:
- Model number or identifier.
- Physical dimensions and
weight.
- Material of construction.
- Maximum allowable working
pressure and temperature.
- Flow rates and connection
sizes.
- Heat transfer area.
- Design standards compliance
(e.g., ASME, TEMA).
- Optional features or
accessories.
- 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.
