Freestanding chimney is a steel exhaust stack that stands by its own shell and base, without a full outside tower frame. It is used when a plant needs a clear vertical discharge point but wants to keep the ground layout simple.
The body is usually made in sections, then checked for roundness, weld line, flange fit, and coating before shipment. In boiler rooms, heating plants, and small industrial workshops, this form saves space and keeps later inspection easier because the outside surface is open to view.
The product can include steel shell sections, base plate, flange rings, ladder or platform parts, lightning rod, inspection port, anchor bolts, and rain cap. Material is selected from carbon steel, stainless steel, or lined steel by gas condition.

Product Advantages
The freestanding chimney keeps the structure direct, so it is easier to arrange in a tight plant yard.
1. It uses less outside framing than a tower-supported system.
2. Section production makes transport and site lifting clearer.
3. The outside body can be checked during routine maintenance.
Main Applications
A freestanding chimney is often used where one exhaust line needs a direct and stable outlet.
Boiler houses with one or two flue gas lines.
Small and medium heating stations in industrial parks.
Workshop ventilation discharge points.
Retrofit sites where an old brick stack is removed.
Our Services
Tengshida can discuss drawing size, wind load, surface finish, packing method, and loading plan before production. For site projects, the work can also include drawing review, material confirmation, factory inspection photos, and basic installation notes.
FAQ
Q: Can it be made for a narrow plant yard?
A: Yes. The freestanding chimney can be designed after the foundation size, wind load, and crane access are checked.
Q: Is stainless steel always needed?
A: No. Stainless steel is selected when gas moisture or corrosion level requires it.
Q: What should be confirmed before quotation?
A: Height, diameter, gas temperature, medium, local wind data, and installation site drawings should be checked first.
