Timing — the ability to quickly turn around a fin tube to get your heat exchanger back online faster — is like a crisp 1,000 dollar bill, the ink so fresh you can smell it.
That’s practically a thermodynamic law of economics for fin tubes and heat exchangers.
Which is why it’s so important to work with a fin tubing manufacturer that has their own in-house machine shop and brazing furnace. This way, they can do all the customization, furnace brazing, and tweaking for the tube onsite — where the sausage meets the grinder, so to speak.
The finned tube is already fin formed, brazed, and ready to go upon delivery — a plug-in & play maintenance model you can practically screw in like a lightbulb.
You get the parts and tubes faster because there’s less shipping back and forth. What would have taken months can now be done in weeks — and weeks become just a few days. The accelerated timing can almost give you goosebumps.
How Soon Do You Need It? No Problemo!
A machine shop model allows finned tube manufacturers to churn out spontaneous prototypes with surprising momentum. What would have taken 4 to 6 weeks to ship out to another shop for customization and tooling can be done onsite in 2 to 3 hours.
With an in-house controlled atmosphere furnace, your manufacturer can do all the furnace brazing or annealing on site. You just saved yourself at least a week in redundant outsourcing.
High tolerance customizations can be quality controlled on-site. With a machine shop, you can machine your own testing fixture with the tolerance built-in. Once you’re done flexing the tube, drop it right into the fixture. You’ll know that extreme high tolerance is precisely .1 — right on the dot.
Pipes can be fin formed before delivery. Custom in-house tooling can be tweaked on the spot — while the pipe is still soft to be malleable — like molding a wet noodle before it solidifies into a rigid piece of stainless steel fin tubing.
Coiling vs. Welding — the Quality Difference
Furnace brazing enhances the bond between the fins and the tubing. At the same time, this process anneals or softens the tubing to be bendable. By brazing the tube on-site, harder stainless steel metals can be instantly coiled in the initial production stage. Unlike a weld, the tube doesn’t suffer or become brittle. The tubing stays intact throughout the machining process. This approach isn’t just faster — it’s a better quality that can stand up to the wear and tear of time.
Accessories & In-house Heat Exchangers: A New Approach
With its own machine shop, the fin tube manufacturer can also offer parts and accessories for your fin tube.
- Tube sheets
- Support Collars
For better quality control, a manufacturer with a machine shop and brazing furnace can even build ASME heat exchanger components and sub assemblies onsite from the ground up. This simplifies the physics and the math because everything can be double-checked, lined up and ready to go upon delivery. The baffles, components, and tube sheets fit perfectly. The tube is fin formed precisely and fits like a key in a padlock. The heat exchanger assembly is already tested and quality controlled before it’s shipped on a truck.
And all your problems? Neatly checked in a box; crossed off your to-do list.
One Source — One Price — One Delivery
Naturally, having a fin tube customized, brazed, and fin formed will cost a little more than a tube you machine or braze yourself or outsource somewhere else. But overall you can actually save money. A manufacturer ready to machine up and braze the whole enchilada can offer a clean price break. You eliminate markups and fees you’d otherwise pay customizing, brazing, or buying the components from 5 different suppliers.
It’s a cleaner and more efficient way to work. In the end, there’s less dead weight. You’re free to tackle any daunting deadline, light as a feather — like a bird soaring into a sunset of pure possibility.
