Pressure class and sealing surface of liquid ammonia tank nozzles
Thread Content
As the title suggests, should I choose CL150 or 300 for the American standard? Should the sealing surface be RF or MFM? I’d like to ask everyone for advice
The nozzles are generally CL300, and MFM is recommended for the sealing surfaces as it provides better sealing performance. But many design institutes say that MFM is not needed. If you have money, use MFM.
Are textured surfaces that expensive? Of course, this sealed surface is of better quality
