2). Leg supports shall be limited to spherical and cylindrical vessels that meet the following requirements:

• Design temperature does not exceed 450oF (232oC).

• Service is noncyclic and nonpulsating.

• Vessel height-to-diameter ratio does not exceed 5. (Height is defined as the distance from base of support to the top tangent line of the vessel.
