Pressure Vessels – Vessel Supports, Ladder and Platform
Small vertical vessels may be supported by angle support legs, as shown in Figure 12-11. Larger vertical vessels are generally supported by a skirt support, as shown in Figure 12-12. At least two (2) vent holes, 180° apart, should be provided at the uppermost location in the skirt to prevent the accumulation of gas, which may create explosive conditions. Horizontal vessels are generally supported by a pair of saddle type supports.
Ladder and Platform
Ladder and platform should be provided if operators are required to climb up to the top of the vessel regularly. An example is shown in Figure 12-1.3.
