SHELL & TUBE

Shell & Tube
Heat Exchanger.

A Shell and Tube is the most common type of heat exchanger used in applications that require higher pressures and temperatures. Consisting of a tube bundle inside a shell, this basic design is heavy duty, rugged and durable. The system is simple, two fluids of different temperatures are circulated through the heat exchanger. One fluid flows through the tubes while another fluid flows over the tubes providing an optimum and efficient heat transfer.

Advantages of a Shell & Tube

Application

Higher pressure and temperature options available

Design

Basic, heavy duty, rugged and durable

Lifespan

Average life is 15-20 years; however it is
not uncommon to be in service for over 30 years

Economical

Typically less expensive than other types of
heat exchangers including a plate and frame

Main Components of a Shell & Tube 

Shell & Tube Components
Tube & Bundle Tubes
Tube & Bundle Baffles & Tie Rods
The tubes are typically copper or stainless steel with a ¾" or 5/8" outside diameter, while the remaining components are usually manufactured from milled steel.
Tie rods (circular metal rods) and spacers hold the tube bundle together while holding the baffles in the correct position. The tie rods are fastened into the tube sheet then secured at the farthest baffle. The number of tie rods, baffles and tubes depends on shell diameter and required application.

Potential Issues with a Shell & Tube Heat Exchanger

  1. When vacuum breakers or thermostatic vents are not installed or functional the tube can be sucked in and break.
  2. If the bundle is subjected to temperature extremes (thermal shock), the tubes will develop spiral cracks.
  3. On steam applications, harmonics can occur. This constant vibration can cause the steel
  4. baffles to eventually cut into the copper tubes.
  5. Chemical corrosion resulting from interaction between the heat exchanger and the circulated fluids.
  6. Marine film or coating on tubes such as scale, mud, algae and zebra mussels plugging tubes, this results in higher corrosion and restricts heat flow.

Industrial Oil Cooler Cleaning / Cleaning Services

We Clean Industrial Oil Coolers. Oil cooler service across many industries. Oil Cooler clients are provided superior cleaning results.

Oil cooler maintenance in Ontario and beyond with Heat Exchanger Ontario

THS is fully equipped to repair and service industrial oil coolers (internal/external) cleaning, flushing and pressure testing. The Heat Exchanger Ontario Oil Cooler Service Centre can overhaul and refurbish your system.

If your oil cooler has failed, we can recore your cooler or supply a replacement.

Failure of an oil cooler can lead to failure of the engine or the component it is designed to cool. An oil cooler is a heat exchanger which is responsible for cooling your equipment's oil. It removes excess heat by continuously passing through a heat exchanger which is cooled by air or water.

A failing oil cooler can also cause contamination of the cooling system. A THS Service Team can service and pressure test your oil cooler to ensure it is performing at its best.

The oil cooler is a major heat exchanger component for your equipment, removing excess heat from your cooling system. Oil cooler maintenance prevents failure, that can lead to engine failure if left unchecked. THS Oil Cooler Service provides regular servicing and pressure testing of your oil cooler in Ontario

An oil cooler is an essential component of your equipment's cooling system. During operation, it's responsible for regulating the temperature of your equipment's oil.

Industrial equipment often operates in harsh environments. Radiators are subject to damage and premature breakdowns. T.H. Industrial solutions offer cooling solutions to improve the durability and performance of your industrial equipment. We will service, repair, upgrade, and supply new replacement radiators and coolers. Along with custom solutions to fit your specific application.

Heat Exchanger Ontario Innovative products and solutions are available to prolong the life of your radiators, such as solder coating, Shield cores, dummy rows, corrosion resistant paints, and tank upgrades. THS Service experience in the industrial sector is here to help you.

SHELL & TUBE HEAT EXCHANGERS ISSUES

  1. When vacuum breakers or thermostatic vents are not installed or functional the tube can be sucked in and break.

  2. If the bundle is subjected to temperature extremes, (thermal shock), the tubes will develop spiral cracks.

  3. On steam applications, harmonics can occur. This constant vibration can cause the steel baffles to eventually cut into the copper tubes.

  4. Chemical corrosion resulting from interaction between the heat exchanger and the circulated fluids.

  5. this results in higher corrosion and restricts heat flow

Heat Exchanger Ontario, a division of T. H. Industrial Solutions Inc.'s (THS) has been servicing industrial heat exchangers and solving process problems across Canada since 2009. THS head office is located in Pickering, Ontario with a 6,000 square foot service center in Hamilton, Ontario.

Today there are fewer qualified people in this industry that know the products and understand the applications. Utilizing hands on experience and knowledge that has been gained by our THS sales and service technicians for over the past 30 years, we will take the time to understand what you require and strive to provide a prompt, educated and accurate response at a competitive price.
