Selection of sealing surface for benzene tank connection flange
Thread Content
For the sealing surface of the benzene tank connection flange, should RF or MFM be chosen? Storage, transportation, and on-site applications tend to favor RF. Are there any regulations regarding the selection of sealing surfaces for pipe flanges in media containing benzene? It is said that MFM is better than RF, but on-site there is strong demand for the RF version. What are your thoughts?
MFM has good sealing performance, but it is more expensive. Using RF can improve the flange rating, resulting in less leakage.
Whether to choose RF or MFM for the sealing surface of the benzene tank connection flange is actually not a problem; the key is that the flange rating must be at least 2.5 MPa. MFM has better sealing performance, but its valves are relatively harder to find.
