The graphite heating element is cylindrical and has high heating efficiency.
1. According to relevant public information, the stress of cylindrical graphite plates and cylindrical shells is significantly better than that of rectangular graphite plates, heads and metal cover plates.
2. The metal parts are not too heavy and can increase the working pressure. The operating pressure of this type of graphite plate heat exchanger abroad has reached 2.1MPa. The rectangular one does not have as high a heating efficiency as the cylindrical one.
