Chuzhou Qidi Instrument Co., Ltd. announces the release of 2507 duplex stainless steel pressure gauges specifically designed for seawater desalination in marine engineering

Chuzhou Qidi Instrument Co., Ltd. (formerly known as Tianchang Qidi Automation Instrument Co., Ltd.) announced the launch of the 2507 duplex stainless steel pressure gauge designed specifically for the fields of marine engineering and seawater desalination. This product is made of 2507 duplex special steel material, optimized for high chloride ion and high-pressure corrosive environments, ensuring long-term monitoring stability and reliability in seawater desalination systems.

Product Core Features

Corrosion resistance: 2507 duplex steel exhibits excellent performance in chloride containing ion media, with critical pitting temperature (CPT) and pitting re passivation temperature (PRT) far exceeding traditional stainless steel (such as 316L). It can effectively resist electrochemical corrosion, pitting corrosion, and stress corrosion cracking in seawater desalination processes, extending equipment life to more than 5 years.

Structural advantages: Adopting unobstructed flow design, suitable for high temperature and high pressure industrial pipelines, supporting bidirectional measurement, suitable for flow monitoring of acid, alkali and highly corrosive media, reducing operation and maintenance costs by more than 70%.

Industry Applications and Cases

In the field of seawater desalination, this pressure gauge has been successfully applied in reverse osmosis factories, such as the Taweelah project in the United Arab Emirates. It can withstand chloride ion concentrations exceeding 20000ppm, increase compressive strength by 45%, and significantly reduce equipment replacement frequency.

Covering key scenarios of ocean engineering, including deep-sea oil and gas exploitation, scenery complementary micro grid equipment and large-scale breeding factory ship, to meet the demand for high-precision pressure measurement under extreme conditions and support the strategic incremental goal of water resources
