Elevating Fire Protection，The Pivotal Role of Epoxy Coated Steel Tanks in Safeguarding Lives and Property
In modern society, the constant presence of the risk of fire poses a potential threat to the lives and property of individuals. Therefore, effective fire prevention measures are crucial. The firewater tank, as a core component of the fire protection system, plays an irreplaceable role in disaster prevention and relief. It stores and provides firewater, offering critical support to firefighters in responding rapidly to emergencies.
The firewater tank, a key component in the fire response system, bears the responsibility of storing and supplying water. Its significance during the firefighting process is not only evident in providing a stable and enduring water source but also in meeting the diverse requirements of different fire scenarios, thereby enhancing firefighting effectiveness. Hence, the design, material selection, and equipment of firewater tanks are crucial to ensuring the reliability and efficiency of fire prevention and control systems.
In the pursuit of improved performance and durability of firewater tanks, Epoxy Coated Steel Tanks have garnered increasing attention as an advanced water storage material. Their role in firewater tanks extends beyond water storage to encompass superior corrosion resistance, lightweight design, and long-term stability. The unique contributions of Epoxy Coated Steel Tanks in enhancing the functionality and efficiency of firewater tanks provide robust support for the construction of safer and more reliable fire protection systems.
Introduction to Epoxy Coated Steel Tanks
With over 30 years of experience in tank research, production, and construction, Zhengzhong Technology, in collaboration with the globally leading paint and coating manufacturer AkzoNobel, has developed the Fusion-Bonded Epoxy (FBE) coating technology. FBE coating is an advanced anti-corrosion coating known for its excellent corrosion resistance and adhesion. Additionally, the FBE coating technology employs a special application process—electrostatic spraying technology—that enhances coating uniformity and adhesion, effectively extending the lifespan of the tank.
Epoxy Coated Steel Tanks formed using FBE coating technology are not only technologically advanced and cost-effective but also easy and quick to install. The quality meets requirements such as AWWA D103-09 and ISO 9227 / ASTM B117, gaining recognition from customers upon its introduction.

Color Difference Inspection:
Each batch of tanks undergoes inspection using a colorimeter or related color comparison standards to detect color differences on the tank surface, ensuring color consistency.
Adhesion Inspection (Dry Method):
Each batch of tanks undergoes inspection using an adhesion tester, conducting tests such as grid-cutting, scraping, or stretching to evaluate the adhesion performance between the coating and substrate.
Hardness Inspection:
Periodic inspections are conducted using a hardness tester at specified intervals to measure the hardness of the epoxy resin coating, ensuring compliance with requirements.
70°C Hot Water Immersion Test:
Tanks are immersed in 70°C hot water for a specified time and frequency to test performance changes, including adhesion and hardness.
Salt Spray Test:
Tanks are placed in a salt spray test chamber for a specified time and frequency to simulate a marine environment, testing the tanks' corrosion resistance.
Chemical Resistance Test:
Tanks undergo testing by exposing them to different chemical media for a specified time and frequency to evaluate chemical resistance, including the stability of the coating and the degree of damage.
Wear Resistance Test:
Periodic inspections are conducted using a wear test machine to evaluate the wear resistance of the coating.
Impact Resistance Test:
Each batch of epoxy resin undergoes inspection using an impact test machine to assess the impact resistance of the steel plates.
Weather Resistance Test:
Tanks are subjected to testing at specified intervals by placing them in simulated natural weather conditions to evaluate weather resistance, including color stability and appearance changes.
