What are the anti-corrosion designs of fire extinguisher pressure gauge

In modern fire safety equipment, the fire extinguisher pressure gauge is a key component, and the reliability and durability of its performance are directly related to the use effect of the fire extinguisher. Ningbo Kaituo's technical accumulation and innovation in this field ensure the excellent performance of its products in various environments.

Material selection: high-quality corrosion-resistant alloys
Ningbo Kaituo uses high-quality corrosion-resistant alloys as the main materials for the shell and internal key components of the fire extinguisher pressure gauge. These alloys not only have high strength and excellent mechanical properties, but more importantly, they show excellent resistance to a variety of corrosive media. Taking stainless steel 316L as an example, its performance in chloride corrosion resistance is particularly outstanding, so it is widely used in various harsh environments. In addition, titanium alloy is an ideal choice for extreme environments due to its light weight, high strength and excellent corrosion resistance. Through precise material selection, Ningbo Kaituo ensures the long-term stability of its pressure gauge in a variety of harsh environments, and truly achieves high reliability of the product.

Surface treatment technology: improve the durability of the anti-corrosion layer
In addition to material selection, Ningbo Kaituo also introduced advanced surface treatment technology to further enhance the anti-corrosion performance of the pressure gauge. Electroplating and sandblasting are two widely used surface treatment methods. Electroplating technology significantly improves the corrosion resistance and wear resistance of the product by depositing a dense metal coating (such as nickel, chromium or zinc) on the metal surface. Sandblasting uses high-speed spraying of abrasive particles to clean and roughen the metal surface, thereby enhancing the bonding between the coating and the substrate. Ningbo Kaituo combines these two technologies to develop a unique composite anti-corrosion coating. This coating not only has excellent corrosion resistance, but also effectively resists mechanical wear and scratches, ensuring that the product maintains good appearance and performance during long-term use.

Sealing structure design: prevent internal corrosion
The fire extinguisher pressure gauge is usually filled with non-corrosive liquid or gas to transmit pressure signals. In order to prevent the internal medium from contacting the external corrosive environment, Ningbo Kaituo has deeply optimized the sealing structure design of the pressure gauge. The company uses advanced O-ring sealing technology to ensure the tight connection between the components. At the same time, for high-pressure and high-temperature environments, Ningbo Kaituo has developed a special metal-metal sealing structure. Through precise machining and heat treatment processes, the structure achieves extremely high sealing performance and corrosion resistance, ensuring the stability and safety of the product under extreme conditions.

Comprehensive performance and application areas
Ningbo Kaituo's fire extinguisher pressure gauge has excellent comprehensive performance due to its excellent material selection, advanced surface treatment technology and precise sealing structure design. This product is widely used in many fields such as industry, construction, and chemical industry, especially in occasions with extremely high safety requirements, which can effectively ensure the reliability of fire-fighting equipment. Ningbo Kaituo has always been committed to providing customers with high-quality fire safety solutions, and through continuous technological innovation and strict quality control, it ensures that each product can play an important role at critical moments.
