shell and tube heat exchanger

Product Overview

A Shell and Tube Heat Exchanger is the most widely used type of heat exchanger in industrial applications. It consists of a series of tubes (the tube bundle) housed inside a cylindrical shell, allowing two fluids to exchange heat—one flowing inside the tubes (tube side) and the other flowing outside the tubes within the shell (shell side)—without mixing.

Weihai Shidao Heavy Industry Co., Ltd. is a leading Chinese manufacturer of high-performance Shell and Tube Heat Exchangers engineered for demanding industrial environments. With over two decades of experience and full certifications including ASME U Stamp, PED, and ISO 9001, Weihai Shidao designs and fabricates custom exchangers tailored to critical applications in oil & gas, petrochemical, chemical processing, and power generation industries.

FAQs

A shell and tube heat exchanger is a type of heat transfer equipment that consists of a bundle of tubes inside a cylindrical shell. One fluid flows through the tubes (tube side), while another flows around the tubes within the shell (shell side), allowing heat to be exchanged between the two fluids without mixing them.

A shell and tube heat exchanger works by transferring heat between two fluids—one flowing inside the tubes (tube side) and one flowing outside the tubes, within the shell (shell side)—without mixing them. Heat flows through the walls of the tubes, from the hot fluid to the cold fluid, using conduction and convection.

Basic Structure and Flow Paths

ComponentFunction
TubesCarry one of the fluids (usually the cleaner or higher-pressure one)
ShellEncases the tube bundle and carries the second fluid
Tube SheetsHold the tubes in position and seal them from the shell-side fluid
BafflesGuide the shell-side fluid back and forth across the tubes to enhance heat transfer
Channel HeadContains the tube-side inlet and outlet connections
NozzlesInlet and outlet ports for both fluids

Working Process – Flow Overview

StepDescription
1The hot fluid enters either the tube side or shell side, depending on process needs
2The cold fluid enters the opposite side (tube or shell)
3Heat transfers from the hotter fluid through the tube wall to the colder fluid
4The fluids exit the exchanger at their new temperatures, without mixing

Design Variations

Flow ConfigurationDescription
Counter-flowFluids move in opposite directions for maximum temperature gradient
Parallel-flowBoth fluids move in the same direction (less efficient)
Cross-flowFluids move perpendicularly (less common in S&T designs)
Multi-passOne fluid passes through multiple passes to increase heat transfer

The typical design pressure and temperature range of a shell and tube heat exchanger depends on the materials used, construction design (e.g., TEMA or ASME code), and the application’s process requirements. However, general industrial standards can be summarized as follows:

Typical Design Ranges

ParameterTypical Range
Design Pressure10 bar to 100 bar (145 – 1,450 psi)
Design Temperature-100°C to 600°C (-148°F to 1112°F)

Extended Ranges (Special Applications)

  • Pressure: Up to 1000 bar (14,500 psi) for high-pressure reactors, ammonia/urea loops, or hydrogen reforming.
  • Temperature: Up to 750°C for special metallurgy (e.g., Incoloy, Hastelloy) in fired heaters or process gas coolers.

Factors Influencing Limits

  • Material selection (e.g., carbon steel, stainless steel, titanium, Inconel)
  • Thermal expansion and stress considerations
  • Corrosiveness and fouling of process fluids
  • Standards used (ASME Section VIII, TEMA, PED, etc.)

The price of a shell and tube heat exchanger varies significantly based on factors such as size, material, pressure/temperature ratings, design complexity, and compliance with industry codes. Since these units are often custom-engineered, pricing is typically provided on a case-by-case basis (RFQ).

Typical Price Range (For Reference Only)

Capacity / SizeEstimated Price Range (USD)
Small (5–10 m² heat transfer area)$2,000 – $8,000
Medium (20–50 m²)$10,000 – $30,000
Large industrial (100–500+ m²)$40,000 – $150,000+
High-pressure or exotic material unit$100,000 – $500,000+

⚠️ Note: These are budgetary estimates only. Final pricing depends heavily on technical specifications and compliance requirements.

Main Cost Factors

  1. Heat Transfer Area – Larger surface areas require more tubes, longer shells, and larger frames, which increases cost.

  2. Material Selection – Carbon steel is relatively inexpensive; stainless steel, duplex, titanium, Inconel, and Hastelloy significantly increase cost.

  3. Design Pressure and Temperature – Higher ratings require thicker walls, stronger supports, and stricter testing, all of which add to the price.

  4. Mechanical Design Type – Floating head or U-tube designs are more complex and costly than fixed tube sheet types.

  5. Code & Certification Requirements – ASME U Stamp, PED, TEMA Class R, or third-party inspection adds to fabrication and documentation costs.

  6. Testing Requirements – Radiography (RT), ultrasonic (UT), helium leak test, PMI, and hydrostatic testing increase QA/QC costs.

  7. Delivery & Logistics – Export packaging, international transport, and on-site installation support affect total project cost.

  8. Optional Add-ons – Skid mounting, insulation, automatic cleaning systems, and instrumentation further impact pricing.
