Its products have been widely used in petroleum, petrochemical, chemical, metallurgy, electric power, water conservancy, machinery and many other fields.
In modern industry, precise and efficient control of fluid flow is the key to improving production efficiency and ensuring safe operation. As the core component of this demand, cryogenic gate valves are widely used in important industries such as petroleum, chemical industry and liquefied natural gas. These valves not only need to maintain stable performance at extreme temperatures, but also have excellent sealing and reliability. With the continuous advancement of technology, the innovation and optimization of cryogenic gate valves have become an important direction for the development of the industry. This article will explore the importance of this key equipment and its application in various industrial fields, and analyze its technical details, design challenges and future development trends.
At Dalian LNG receiving station, engineers are doing a "physical examination" on a silver valve. The surface of Low Temperature Gate Valves">Low Temperature Gate Valves is covered with white frost, like a Coke can just taken out of the refrigerator. Technician Xiao Wang explained while recording data: "This low-temperature gate valve must withstand liquid nitrogen at minus 196 degrees. You can see the metal tube extending from its neck here, which is used to isolate the cold air."
In Baosteel's hot rolling workshop, red steel billets are passing through the heating furnace at 1250℃. On the pipe gallery, only 3 meters away from the flames, the valve body of a gate valve was burned dark red. "This is the ability of Inconel 718 material," said Zhang Gong, the equipment director, wiping his sweat. "Look at the thermal imager, the valve cavity temperature is 732℃, but the flange surface is always controlled below 180℃."
In the hydrocracking unit area of Zhenhai Refining and Chemical, engineer Chen Li is calibrating the bolts of the DN80 valve with a torque wrench. "The thickness of this valve body is 1.8 times that of an ordinary gate valve," he tapped the luminous surface, "A182 F22 material is normalized three times during forging, and the grain size can reach ASTM grade 7."
In modern industrial systems, environmental protection and safety have become important issues that cannot be ignored. Fugitive emission gate valves play a vital role as key devices for controlling the release of harmful gases or liquids. These valves effectively prevent the leakage of pollutants and ensure the tightness and reliability of the system by adopting advanced sealing technologies such as double seal design and metal-to-metal contact.
Flange gate valves are a vital control device in pipeline systems, and their main function is to control the flow of fluids. It opens or closes the flow channel by lifting or lowering the built-in gate, thereby achieving precise control of fluid flow. This valve is particularly popular because of its simple and efficient design, providing minimal flow resistance, especially when fully open.
Flanged End Forged Gate Valve plays a key role in high-pressure pipeline systems. As a solid guardian, it is mainly used to regulate fluid flow, especially in high-pressure and high-temperature applications. The valve is made of forged steel material, and its structural strength and toughness are enhanced by high-temperature forging process, so that it can withstand extreme pressure and temperature changes, ensuring stable operation under harsh conditions.
In modern industry, pipeline fluid control equipment is essential. The DIN 3352 Gate Valve is a high-quality valve designed specifically for this purpose. It meets the standards of the German Institute for Standardization (DIN), ensuring its consistency and reliability in the global market.
As a key control element of the pipeline system, cast steel gate valves are of irreplaceable importance in the field of fluid regulation. This valve device, cast from special steel, exhibits excellent performance under various harsh working conditions due to its unique material properties and structural design.
Due to its high carbon content (≤2.11%) and optimized alloy composition, carbon steel materials give gate valves excellent mechanical strength and impact resistance. Under high pressure conditions, the carbon steel valve body can withstand pressure levels exceeding Class 1500, and under high temperature environments (≤560℃), its anti-creep properties effectively prevent valve deformation and ensure long-term sealing stability.
