Due to its high combustion value, low carbon emissions, and clean and green advantages, natural gas has become one of the world's major residential and industrial energy sources. During natural gas transportation, it is compressed into a liquid to improve transportation efficiency and reduce costs. In the process of natural gas liquefaction, transportation, storage and gasification, it must be assisted by ultra-low temperature ball valves under the condition of -165C liquid phase.

Speaking of this ultra-low temperature ball valve, it plays a pivotal role in equipment control in many special environments. So, what is the development level of ultra-low temperature ball valves in China? The following editor will take you to understand.

Ultra-low temperature ball valve has strong weather resistance

The ultra-low temperature ball valve can operate and seal gas at room temperature on the one hand, and can operate and seal liquid at -165 degrees Celsius on the other hand; in addition, the pipeline pressure at minus 165 degrees Celsius is 10MPa, which is more than 30 times the pressure of the tap water pipeline. Strict technical requirements have made this valve product monopolized by many foreign manufacturers for a long time.

Among them, the material of ultra-low temperature ball valve is the key. Many years ago, Shangzhou Valve cooperated with many universities and research institutions to deal with material problems, and selected materials that can resist low temperature, prevent expansion and contraction of cold and heat deformation, and also carry out low-temperature sealing structure. design, etc. Carrying out scientific research day and night, investing a lot of money in scientific research, looking for directions in countless failures, and finally obtaining more cutting-edge technology updates in various obstacles, making it rapidly develop and grow into a A well-known enterprise in the ultra-low temperature ball valve industry.

Ultra-low temperature ball valve technology upgrade

The ultra-low temperature ball valve produced by Shangzhou Valve has reached the highest level in the industry. The external material of this ultra-low temperature ball valve is very innovative. On the one hand, the metal material with two low-temperature treatments is cryogenically treated at a very low temperature below zero. This metal material has a cubic crystal structure that can withstand low temperature and high pressure; on the other hand, the ultra-low temperature ball valve can be used in aerospace and other It can effectively solve the problems of high temperature and low temperature cold and freezing, and achieve full coverage of the application field, and the low temperature performance is very outstanding.

In recent years, Shangzhou has further innovated and upgraded in terms of large diameter and ultra-low temperature, which has greatly improved the weather resistance of ultra-low temperature ball valves. The product adopts a special valve seat design with compensation and support functions. , The ball valve successfully passed the relevant testing, breaking the long-term monopoly of this kind of valve by foreign countries. This not only improves the hard power of Shangzhou Valve Company itself, but also promotes the upgrading of valve technology in the whole country from the perspective of long-term development.
