Ceramic saddle is improved from the arc saddle, Ceramic saddle changes the both arched surface torectangular surface and makes the interior radius of curvature different, this construction overcomes the problem of nesting basically, Ceramic saddle makes porosity distributed even and improves the distribution of the fluid, greater capacity and lower pressrue drop than Rasching ring.
