About the diameter of the chimney

I get some questions about the diameter of the chimney, so I would like to answer them.

Is it possible to join with other companies' chimneys that are currently frequently asked questions?

That's what it means.

The first and foremost thing is to buy a chimney from our shop and if it doesn't fit, you can return it.

Basically, we accept returns within 30 days without any reason, so please order a shorter chimney and check if it can be connected to your existing chimney.

There is a round trip shipping fee, but it is definitely worth trying.

If the male is too big to fit in, there is a tool called a five blade crimper that waves the chimney to narrow the diameter, so you can use it to connect.

This product is also available for rent at our shop, so if you need it, please see the product list.

Another method is to measure the circumference with a cloth tape measure to determine the diameter.

Since I planned the outer circumference of the single chimney before, I will describe it in the hope that it will be helpful.

I measured the actual size of the outer circumference of the single tube at three points.

 Male 476 476 475

Female 483 483 482


The diameter when male 476 female 483 mm is

 Male OD diameter 151.59

Female outer diameter 153.82


The inner diameter of the knife cannot be measured, but the thickness of the stainless steel plate is 0.7 mm for a single pipe, so the inner diameter of the knife will be 152.42 if subtracted 1.4 mm.

From the above, the diameter is calculated as follows.

Outer diameter of male pipe 151.59mm

Female tube inner diameter 152.42mm

As for the diameter, the chimney is distorted, so the complete diameter cannot be obtained, so it was necessary to calculate it.

Please point out any mistakes.
