Q. Explain about Horizontal Vessels?
Horizontal vessels shall preferably be designed for two saddle supports attached by welding. Design of saddle supports and calculation of localized shell stress may be determined by the L. P. Zick method.
The minimum saddle support contact angle shall be 120o. Saddle supports shall preferably be located a maximum distance of Ro/2 from the head tangent line, where Ro is the shell outside radius.
