What is the corrosion resistance of FRP scrubbing towers?

05 20, 2025

FRP scrubbing tower is an important equipment commonly used in the field of industrial waste gas treatment. Its wide application is mainly due to its good corrosion resistance. FRP is a composite material composed of glass fiber reinforced material and thermosetting resin, which has strong physical strength and chemical corrosion resistance. Especially in the purification of acid and alkali gases and the treatment of organic waste gas containing corrosive components, FRP scrubbing towers show strong adaptability.
In the industrial production process, waste gas often contains corrosive chemical components such as hydrogen sulfide, hydrogen chloride, ammonia, fluoride, etc. If the material of the scrubber cannot resist the erosion of these components, it will cause damage to the equipment, shorten its life, and even cause safety hazards. FRP material itself has good chemical stability. When facing a variety of inorganic acids, alkalis and salts, it is not easy to react chemically on the surface, thus avoiding common corrosion problems. Because of this, FRP scrubbing towers can maintain structural stability and airtightness for a long period of time when dealing with such gases.
The surface of FRP material is relatively smooth and pollutants are not easily attached. This feature also indirectly improves its corrosion resistance. Usually during the design process, the inside of the tower body will also be treated with appropriate anti-corrosion coating, which can further improve the durability of the contact surface between the material and the gas. Even in long-term operation, it is not easy to cause structural damage or performance degradation due to corrosion.
In high-humidity environments, metal equipment is prone to rust and structural aging, while FRP itself is non-conductive and non-hygroscopic, and is not prone to corrosive reactions even in environments with high humidity or condensed liquids. FRP washing towers are widely used and valued in industries with high humidity and high corrosion conditions such as electroplating, chemical, pharmaceutical, printing and dyeing.
From actual use feedback, FRP washing towers perform stably in different regions and under different working conditions. Their anti-corrosion properties not only reduce the frequency of maintenance, but also reduce the frequency of equipment replacement, thereby saving maintenance costs for the user unit. Its lightweight and high-strength structure also makes installation and handling relatively simple, and it is less likely to be damaged by external forces during transportation.
The corrosion resistance of FRP washing towers is one of the foundations for their widespread use in the field of environmental protection equipment. Whether in strong acid or strong alkali environments, or in the treatment of waste gas containing salt or organic solvents, FRP materials can provide relatively reliable protection. With the continuous improvement of environmental protection standards and the diversification of processes, the requirements for the durability of scrubbers are getting higher and higher. FRP has maintained a stable market position under this trend and has become a common material of choice for many companies in waste gas treatment solutions.
