It is based on synthetic resin. Glass fiber reinforced composite pipes have the advantages of strong corrosion resistance, light weight, and low fluid resistance. They are mainly used in the fields of chemical engineering, environmental protection (such as wastewater treatment), energy, municipal water supply, etc.

Our company produces various horizontal and vertical containers and storage tanks, which are corrosion-resistant, lightweight and high-strength, with a long service life. They are widely used in petroleum, chemical, textile printing and dyeing, food fermentation, hydraulic irrigation, and national defense engineering.

Fiberglass reinforced plastic (FRP), as a high-performance composite material, has shown wide application value in the field of environmental protection due to its lightweight, high strength, corrosion resistance, aging resistance and other characteristics, and has become an important material for promoting green development. The following provides a detailed introduction from three aspects: material characteristics, environmental applications, and advantages:

1、 Characteristics of fiberglass material
Fiberglass reinforced plastic is composed of glass fibers and resin matrix composite, which combines the excellent properties of both:

Lightweight and High Strength: With a density of only 1/4 to 1/5 of steel, its tensile strength can rival that of alloy steel and even exceed that of carbon steel.
Corrosion resistance: able to resist corrosive media such as acid, alkali, salt, etc., suitable for harsh environments such as chemical and sewage treatment.
Aging resistance: Long term use in environments ranging from -40 ℃ to 120 ℃, with a lifespan of over 50 years, and is not prone to aging and cracking.
Environmentally friendly and non-toxic: free of harmful substances such as formaldehyde and asbestos, in line with international environmental standards, and can be safely applied in fields such as drinking water treatment.
Design flexibility: It can be molded into various complex shapes (such as pipelines, storage tanks, towers, etc.) through molds to meet diverse needs.

2、 The application of fiberglass in the field of environmental protection

1. Sewage treatment and resource utilization
Fiberglass storage tanks and pipelines:
Used for storing and transporting corrosive liquids (such as acid, alkali, salt solutions), replacing traditional steel tanks, and avoiding leakage pollution caused by corrosion. For example, in chemical industrial parks, fiberglass pipelines can safely transport chemical wastewater and reduce maintenance costs.
Integrated sewage treatment equipment:
Integrated biological contact oxidation and other processes are used to treat domestic wastewater and industrial organic wastewater. The equipment adopts fiberglass structure, which is corrosion-resistant and has a long service life. It is suitable for residential areas, hospitals, factories and other scenarios, and the effluent quality can meet the discharge standards.
Glass reinforced plastic septic tank and biogas digester:
In the construction of new rural areas, glass reinforced plastic septic tanks are used for the renovation of rural dry toilets, which are corrosion-resistant and easy to install; Fiberglass biogas digesters achieve the resource utilization of agricultural waste, generate clean energy, and reduce pollution emissions.

2. Air pollution control
Flue gas desulfurization system:
Wet chimneys and flues made of fiberglass can withstand high temperatures (such as power plant flue gas) and corrosive gases (such as SO ₂), effectively reducing the emission of harmful substances such as sulfur dioxide.
Purification tower and deodorization equipment:
Fiberglass purification tower is used for dust removal, desulfurization, denitrification, and efficient removal of pollutants from exhaust gas; The fiberglass biological deodorization box uses microbial degradation technology to treat odorous gases from sewage plants and livestock farms, improving air quality.

3. Energy conservation and water resource management
Cooling tower:
The fiberglass cooling tower reduces the temperature of industrial water through efficient heat exchange, with a water saving rate of up to 20%, while reducing white mist emissions, which meets environmental requirements. For example, in the power and chemical industries, its application significantly reduces water resource consumption and carbon emissions.
Reverse osmosis water treatment vessel:
As a key component of high-performance water treatment equipment, fiberglass pressure vessels are used for deep purification of water quality and ensuring the safety of drinking water.

4. Infrastructure construction
Water supply and drainage system:
Fiberglass pipes are widely used in urban water supply and drainage systems, especially for transporting corrosive media or working in harsh environments such as coastal areas or chemical parks.
Water transmission project:
The fiberglass sand pipe has been successfully applied in the resettlement water supply project of Dachaoshan Power Station in Yunnan, providing an economical and efficient water transmission solution and serving as a reference for water transfer projects in southwestern mountainous areas.

3、 The environmental advantages of fiberglass reinforced plastic
Reduce resource consumption: Lightweight and high-strength characteristics reduce transportation and installation costs, corrosion resistance extends equipment life, and reduces replacement frequency.
Reduce pollution risk: Replace traditional materials (such as steel tanks), avoid leakage pollution caused by corrosion, and ensure environmental safety.
Energy conservation and emission reduction: Cooling towers and other equipment reduce energy consumption through efficient operation, in line with the concept of low-carbon environmental protection; Applications such as biogas digesters can achieve waste resource utilization and reduce greenhouse gas emissions.
Adapt to harsh environments: operate stably in high temperature, high humidity, and corrosive environments, reduce maintenance requirements, and lower lifecycle costs.

4、 Case support
A certain sewage treatment plant: using fiberglass cover plates to solve the problem of covering biological reaction tanks, improving treatment efficiency while avoiding exhaust gas overflow.
Application of fiberglass sand pipe: In the resettlement water supply project of Yunnan Dachaoshan Power Station, fiberglass sand pipe replaces traditional pipe materials to achieve safe, economical, and efficient water delivery goals.
Industrial cooling tower: In the power and chemical industries, fiberglass cooling towers help enterprises achieve carbon neutrality goals through water-saving and energy-saving design.
Fiberglass, with its excellent performance and environmental advantages, has become an important material in fields such as sewage treatment, air treatment, and resource recycling, providing strong support for promoting green and sustainable development.
