Whether the connection mode between the straight through mirror and the pipe or equipment is correct and appropriate will directly affect the probability of running, bubbling, dripping and leaking phenomenon between the pipe and the straight through mirror.
The choice of flange sealing surface style of straight lens mainly considers the pipeline pressure, temperature, medium, and all kinds of circumstances, and chooses the most cost-effective style.
Sealing styles are mainly protruding surface (RF), concave and convex surface (MFM), tenon groove surface (TG), full plane (FF).
