Transportation and construction of pressure vessels
Transportation and construction of pressure vessels The transportation of a pressure vessel by ship, barge, road, or rail will subject the vessel to one-time-only stresses that can bend or permanently deform the vessel if it is not adequately supported or Read More

High Pressure Vessels
High Pressure Vessels Designers and engineers of pressure vessels must eventually become acquainted with the design of vessels for high pressure service. The immediate question is, “What constitutes high pressure”? For purposes of discussion here, high pressure begins around 3,000 Read More
Local Loads
Local Loads Stresses caused by external local loads are a major concern to designers of pressure vessels. The techniques for analyzing local stresses and the methods of handling these loadings to keep these stresses within prescribed limits has been the Read More
Special Designs
Special Designs There are three methods for calculating the strength of reinforcement required for openings in pressure vessels: 1. Area replacement rules per UG-36(b). 2. Analysis per Appendix 1-7. a. 2/3 area replacement rule. b. Membrane-bending stress analysis. 3. FEA. Read More
Vessel Internals
Vessel Internals Process vessels frequently have internal beds that must be supported by the vessel shell. Sand filters, packed columns and reactors with catalyst beds are just a few examples of vessels that have internal beds. The beds are typically Read More
Design of Vessel Supports
Design of Vessel Supports There are various methods that are used in the supportstructures of pressure vessels, as outlined below.• Skirt Supports Cylindrical Conical Pedestal Shear ring • Leg Supports Braced a. Cross braced (pinned and unpinned) b. Sway braced Read More
