Grp chimney is a composite-material stack used for flue gas that may contain moisture, acidic gas, or process vapor. The material is lighter than steel, so it is often chosen for desulfurization towers, chemical exhaust lines, and waste gas treatment systems.
The real grade should be picked after checking gas temperature, acid level, flow rate, and whether particles are present. The inner surface, wall thickness, joint method, and support frame all need to work together, because the chimney is part of a full discharge system, not a separate pipe.
Components
The system can include GRP cylinder sections, resin-rich inner layer, structural layer, support rings, tower frame, flange joints, drain point, inspection port, and top rain cover. The resin system is selected by gas medium.

Product Advantages
The grp chimney gives a lighter body and reduces the need for frequent anti-corrosion repainting.
1. Composite wall helps in damp and acidic gas conditions.
2. Lower body weight can reduce some support load.
3. Sections can be prefabricated for cleaner site work.
Main Applications
A grp chimney is used in wet exhaust projects where corrosion control is a main concern.
1. Chemical plant tail gas discharge.
2. Desulfurization tower outlet stacks.
3. Waste incineration and sewage treatment gas lines.
4. Pharmaceutical and metallurgical exhaust systems.
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 handle all chemical gas?
A: No. A grp chimney should be selected after the gas list, temperature, concentration, and working time are confirmed.
Q: Is a tower frame needed?
A: Many tall projects use a frame, but the final support form depends on height and wind data.
Q: Can the diameter be customized?
A: Yes. Diameter is matched with exhaust volume, flow speed, and project layout.
