Let’s give it our support; I hope everyone will ask questions so that we can solve problems together, learn together, and improve together!
Let me start with the first question: For high-pressure urea angle valves, what standards are used for their connection dimensions?
What are the dimensions of the domestic version, and what are those of the imported version? For use only in CO2 stripping processes and ammonia stripping processes! ! !
Domestic JB/T450—2008
Is the Jb450 only available for DN150 and below? At the same time, in practical use, many valves do not conform to this dimension; for example, the valve samples from Chuanhua Machinery do not meet this standard! ! !
Large sizes are mostly proprietary standards of manufacturers.
In the high-pressure valves used in the ammonia stripping urea process, what standard is adopted for the valve connection dimensions?
