Answers to Common Questions About Industrial Tank Heating Coils
Here, you’ll find answers to some of the questions we hear most frequently about industrial hot oil heating coils.
What is the Difference Between a Helical Tank Coil and a Longitudinal Tank Coil?
Helical tank coils have the coils wrapped around the pipe, while longitudinal tank coils feature fins going the long way along the pipe. You can see the difference in these two styles in the photo below.
For most applications, helical tank coils are the better way to go as they offer a number of advantages, including:
- Better heat transfer
- Reduced cost
- Higher efficiency
- Reduced coking
Are Helically Wound Fins or Longitudinal Fins the Better Way to Go When it Comes to Tank Coils?
A tank coil with a helical wound fin after decades of use. Proof that fouling does not occur when using the right fin and operating the tank coils the right way!
As mentioned above, for most applications, tank coils with helically wound fins are the better option. They offer numerous advantages when compared to coils with longitudinal fins, including improved heat transfer and higher efficiency.
One of the main advantages of tank coils with helically wound fins is the fact that they significantly reduce coking. As you can see in the photo, fouling of the coil does not occur when the proper type of fin is used and the heater is operated properly, even after decades of use.
The coil pictured here was used for 20 years and is still in terrific shape!
If you’re unsure of which tank coil fin style will be best for your specific application, don’t hesitate to reach out to us and we can point you in the right direction.
What is the Difference Between a Helical Coil and a Bare Pipe Coil?
Helically wound coils provide a number of advantages over bare pipe tank heating coils. First off, they offer increased surface area, which means that you’ll need significantly less pipe to heat the material in the tank. This means helical tank coils can be a significantly smaller investment when it comes to purchasing them for your facility.
Well designed helical tank coils can also help to prevent some of the tank heating issues that often come along with bare pipe coils, which are often crowded on the bottom of the tank.
Helical tank coils from Enerquip can also boast faster installation, lower installation costs, and customization options.
Should My Tank Coils Be ASME Code Stamped?
The short answer to this question is: Yes. ASME code was established in an effort to prevent accidents by making boilers, pressure vessels and heating equipment safer. Equipment that is ASME stamped has been thoroughly inspected for quality and meets the standards established by the Boiler & Pressure Vessel Code.
All of our tank coils meet ASME code standards and can be code stamped.
Do You Offer Custom Tank Coils?
We absolutely do! Our storage tank heating coils are custom built to meet the specific criteria outlined by our clients and designed to meet each facility’s unique needs.
Our engineers can do an exact thermal calculation based on your boiler or thermal fluid heater. We can also take the layout of your storage tank into account, enabling us to create a tank coil solution that’s completely customized for you.
