Chuzhou Qidi Instrument Co., Ltd. (formerly known as Tianchang Qidi Automation Instrument Co., Ltd.) announced the launch of a high-performance pressure measuring equipment for marine engineering and seawater desalination -2205 duplex stainless steel pressure gauge. This product is designed for harsh corrosive environments and is made of 2205 duplex stainless steel material, significantly improving its resistance to pitting corrosion and re passivation in chloride ion enrichment scenarios (such as seawater desalination systems), reducing the risk of equipment failure.

Core advantages of the product

Material characteristics: 2205 duplex stainless steel maintains passivation film stability at high temperatures and high chloride ion concentrations. Its critical pitting temperature (CPT) and pitting re passivation temperature (PRT) perform better than traditional stainless steel (such as 316LSS), ensuring long-term monitoring reliability.

Application adaptation: adapt to the new energy driven desalination system (such as wind solar complementary micro grid equipment), marine engineering pipelines and large-scale breeding factory ship pressure monitoring scenarios to meet the needs of high-precision and high durability

Industry background and demand

The seawater desalination industry is accelerating technological innovation. In the first half of 2025, China will make breakthroughs in solar desalination, large-scale breeding factory ship and other fields, driving the demand for corrosion resistant instruments to increase by 25%. The launch of 2205 material pressure gauges fills the gap of domestic high-end pressure measuring equipment in marine corrosive environments, supporting the achievement of water resource strategic increment goals

Chuzhou Qidi Instrument Co., Ltd. will continue to optimize its product line, focus on the research and development of industrial automation instruments, and promote technological iteration and market service upgrades.
