The frp industrial chimney is a composite chimney system used to discharge corrosive gas from desulfurization, chemical exhaust, metallurgy, sewage treatment, and waste incineration systems. The fiberglass body resists acid mist and wet flue gas better than common carbon steel, so it is useful when the gas contains SO₂, HCl, moisture, or other corrosive media. The structure can be made as a single stack or combined with a tower frame, with diameter and height adjusted to fan pressure, gas temperature, site wind load, and outlet position.

Components
1. Cylinder sections, flange rings, access port, drainage point, platform connector, and tower fixing parts can be supplied by drawing.
2. The inner surface can use resin and fiberglass layers selected for acid gas, wet gas, or general exhaust conditions.
3. When the frp industrial chimney is used with a steel tower, the fixing brackets and vibration control parts should be checked together.
Product Advantages
Fiberglass structure helps reduce corrosion repair in wet flue gas areas where ordinary steel paint may age faster.
Lightweight chimney sections reduce hoisting pressure, especially for medium-height stacks or roof equipment areas.
Custom diameter design keeps exhaust velocity within the project range instead of forcing one fixed stack size.
FAQ
Q: Can the chimney be used for high-temperature gas?
A: It should be checked by gas temperature and resin type. FRP is more suitable for medium and low temperature corrosive gas, not direct high-temperature flame gas.
Q: What should be confirmed before production?
A: Gas composition, temperature, air volume, height, diameter, wind load, outlet position, and support form should be confirmed.
Q: Is the frp industrial chimney supplied in one piece?
A: Large units are usually supplied in sections, which makes transport and site lifting easier.
