What factors affect the high and low temperature resistance of water tank spring?

Ningbo Chaoying Spring Industry & Trade Co., Ltd. is a professional spring manufacturer with rich technical experience over the years. The company has a research and development team composed of senior engineers and technicians who keep pace with the times and constantly explore new technologies and processes. On the basis of inheriting traditional manufacturing processes, the company continues to innovate and develop a series of new products with independent intellectual property rights. These products have a place in the domestic market and are also exported to many countries and regions overseas. Water Tank Spring is one of our products. The following will focus on the factors that affect its high and low temperature resistance.

Water tank spring is one of the key components in the water tank system and is widely used in valve control, cover support and water flow regulation of various water tanks. In these scenarios, springs must cope with operating requirements in different temperature environments. For example, in the water tank of a water heater, the spring needs to be able to withstand higher temperatures, while in the water tank of an industrial refrigeration system, the spring must have excellent low temperature resistance. In these different environments, the performance of the spring must remain stable and avoid failure or performance degradation caused by high or low temperatures. Therefore, understanding the key factors that affect the high and low temperature resistance of water tank springs is essential for optimizing spring design and extending its service life.

1. Material selection
The selection of materials is one of the most important factors affecting the high temperature resistance of springs. In high temperature environments, conventional carbon steel springs are prone to oxidation or creep, which leads to spring failure. In order to cope with this situation, Ningbo Chaoying Spring Industry & Trade Co., Ltd. usually uses stainless steel or high temperature alloy steel materials with better heat resistance when designing water tank springs.
Stainless steels such as 304 and 316 show superior corrosion resistance and oxidation resistance in high temperature environments, and can maintain elasticity in environments exceeding 200 degrees Celsius. In addition, high temperature alloy steels (such as Inconel series) can still maintain good mechanical properties at higher temperatures and avoid high temperature embrittlement. The application of these materials greatly improves the durability and reliability of water tank springs under high temperature conditions.

2. Surface treatment process
In addition to the material itself, the surface treatment process is also a key factor affecting the high temperature resistance of the spring. During the production process, Ningbo Chaoying Spring Industry & Trade Co., Ltd. adds a protective barrier to the spring through surface processes such as galvanizing, oxidation treatment or nitriding treatment. This can not only improve the anti-oxidation performance of the spring and reduce oxidation loss in high temperature environment, but also enhance the hardness of the spring surface and improve its wear resistance.
Especially in the oxidation treatment process, a dense oxide film will be formed on the surface of the spring, which can effectively prevent the oxygen in the air from reacting with the metal at high temperature and delay the aging process of the spring. This treatment method ensures that the water tank spring still maintains its good elasticity and strength during long-term high-temperature use.

3. Structural design
The structural design of the water tank spring also has a significant impact on its high temperature resistance. In particular, the setting of the wire diameter, number of turns and preload of the spring directly affects the stress distribution and thermal expansion behavior of the spring in a high temperature environment.
Ningbo Chaoying Spring Industry & Trade Co., Ltd. optimizes the geometric parameters of the spring through precise design calculations, so that it can withstand more uniform stress distribution at high temperature and reduce local stress concentration. This extends the service life of the spring and reduces the risk of failure of the spring due to thermal expansion in a high temperature environment.

4. Low temperature brittleness of the material
In a low temperature environment, the material is prone to embrittlement, that is, the material becomes more likely to break or lose elasticity at low temperatures. In order to meet this challenge, Ningbo Chaoying Spring Industry & Trade Co., Ltd. must consider its toughness performance in a low temperature environment when selecting water tank spring materials.
Some stainless steel materials (such as 304 and 316 stainless steel) can maintain good toughness in a low temperature environment and avoid brittle fracture. In addition, Ningbo Chaoying Spring Industry & Trade Co., Ltd. will also select some low-temperature alloy steels, which can maintain good elasticity at low temperatures and have excellent impact resistance.

5. Stress relaxation phenomenon
In a low temperature environment, the spring may experience stress relaxation, that is, under long-term stress, the restoring force of the spring gradually weakens, resulting in the inability of the spring to effectively reset. In order to avoid this phenomenon, Ningbo Chaoying Spring Industry & Trade Co., Ltd. specially considers the stress distribution at low temperatures and the elastic modulus of the material in the spring design.
Through reasonable wire diameter and number of turns design, Ningbo Chaoying Spring Industry & Trade Co., Ltd. ensures that the spring can still maintain sufficient restoring force in low temperature environment. In addition, the choice of materials is also crucial. It is necessary to ensure that the material has sufficient elastic modulus in low temperature environment to avoid failure of the spring due to stress relaxation.

6. The effect of surface treatment on low temperature performance
Similar to high temperature environment, surface treatment can also improve the performance of springs in low temperature environment. In particular, processes such as nitriding, nickel plating or zinc plating can provide an additional protective layer for the spring to prevent corrosive substances in low temperature environment from damaging the spring surface.
In low temperature environment, the surface of the spring is more susceptible to condensation or frost, resulting in surface corrosion or wear. Through reasonable surface treatment, we can effectively extend the service life of the spring in low temperature environment and ensure its long-term stable operation.

In order to ensure that our water tank springs can maintain excellent performance in both high and low temperature environments, we conducted extensive environmental simulation tests during the product development stage. Through repeated experiments under different temperature conditions, Ningbo Chaoying Spring Industry & Trade Co., Ltd. verified the stress relaxation, elastic recovery and corrosion resistance of the spring in high and low temperature environments.
In these tests, Ningbo Chaoying Spring Industry & Trade Co., Ltd. simulated the working conditions in actual use by exposing the springs to extreme temperature environments. With the feedback of these data, we further optimized the design and material selection of the springs to ensure that our water tank springs can meet the needs of various extreme environments.

As a company committed to innovation and quality, Ningbo Chaoying Spring Industry & Trade Co., Ltd. always puts customer needs first. Our water tank springs are designed with excellence, and also ensure their excellent performance in high and low temperature environments through high-quality material selection and advanced manufacturing processes.
