Stainless steel gate valves also have strong adaptability

In fact, for many users, when choosing a gate valve, they also prefer to choose stainless steel gate valves. The reason for this is also due to many factors. So, what are the factors that affect it? Firstly, this type of gate valve has strong corrosion resistance when used. Nowadays, there are many liquids that have good corrosiveness, so using other gate valves naturally cannot achieve good adaptability.

CITIC Construction Investment: Significantly increase in value, flexible and direct converter valves have strong investment flexibility

According to a research report released by CITIC Construction Investment Corporation (601066), flexible DC transmission engineering is an important tool for solving the problem of new energy consumption and an important driving force for power grid investment from 2024 to 2025. Flexible DC technology is more suitable for long-distance transmission (transmission end) of new energy, multi terminal interconnection (reception end), and long-distance offshore wind power transmission, and has become the preferred solution for ultra-high voltage DC. Converter valves are the equipment with the highest value in flexible DC transmission lines. The value of flexible DC valves in a single converter station can reach 2-2.5 billion yuan, which is much higher than that of conventional DC converter valves. Therefore, the increase in penetration rate of flexible technology will bring elasticity to the converter valve industry chain (equipment, core components).

Overcoming the "bottleneck" problem and accelerating the localization of key equipment for national pipeline LNG receiving stations

The unloading arm, ultra-low temperature safety valve, and ultra-low temperature butterfly valve are all core key equipment of LNG (liquefied natural gas) receiving stations. China's LNG industry started relatively late, and due to its high technological content, it has long been controlled by foreign enterprises for its core technology. These key equipment have long relied on imports, which has constrained the construction of LNG receiving stations in China. The COVID-19 has led to the failure of foreign manufacturers to supply goods on schedule, increased the risk of foreign procurement, and also restricted the project operation and maintenance support capacity.

China's independently developed high-end large-diameter valves are accelerating their application in national key engineering projects

On December 28, 2023, the reporter learned from the National Pipeline Construction Project Management Branch that the NPS24 900 pound forced sealing ball valve led by the company has successfully passed localization appraisal and industrial testing, and has been applied to the Shenyang metering station on the China Russia East Line. The product is also planned to be promoted and applied in the construction of the National High Flow Measurement Station Guiyang Branch, West East Gas Pipeline 3, West East Gas Pipeline 4, and subsequent gas pipeline and measurement station projects undertaken by the National Pipeline Construction Project Management Branch.
