Non-combustible pipe for range hood ventilation, 150mm diameter

This is a flanged pipe made of steel with a plate thickness of 0.5mm.

I purchased this for a DIY range hood installation, but ended up not using it, so I am selling it.
It does not come with a box; it will be shipped in a cardboard box with cushioning material.

[Product Information]
The non-combustible pipe Φ150 has a tapered inner wall, making it smaller on the inside, so a nipple for connecting to spiral ducts is not required.
It is used for range hood ventilation openings and penetrations in fire-resistant, semi-fire-resistant buildings, and buildings compliant with ministerial ordinances for fire resistance, where non-combustible materials are specified.
