For atmospheric-pressure equipment, which is better: adding transverse reinforcement inside the equipment or outside it?

In engineering practice, whether to install transverse reinforcing ribs inside the equipment at normal pressure or outside it depends on a comprehensive consideration of factors such as the specific application of the equipment, design requirements, manufacturing processes, cost considerations, and the convenience of maintenance. Generally speaking, the advantages and disadvantages of reinforcing ribs on the outside of equipment are as follows: Advantages: 1. Easy to process: Adding reinforcing ribs to the outside of equipment usually makes processing and welding operations simpler, thus saving time. 2. Easy maintenance: The external reinforcement strips are easy to inspect and maintain, and it is also convenient to repair or replace them if necessary. 3. Internal space: It does not occupy internal space in the device, having little impact on fluid flow and internal cleaning. Disadvantages: 1. It may affect the device’s appearance and installation dimensions, and it may not be suitable in spaces with limited space. 2. It may have a certain impact on the insulation or coating on the outer surface of the equipment. The advantages and disadvantages of installing horizontal reinforcing ribs inside the equipment are as follows: Advantages: 1. It does not affect the appearance or dimensions of the equipment, nor does it impact external insulation or other treatments. 2. It is more suitable for applications with aesthetic requirements or limited external space. Disadvantages: 1. Difficult to process: For large-scale equipment, internal processing and welding can be quite challenging. 2. Difficult to maintain: Once there are problems with the reinforcement bars, it is troublesome to carry out maintenance and replacement, especially while the equipment is in operation. 3. Space occupation: It takes up internal space in the device, which may affect the flow and cleaning of the internal media. In summary, which method is better depends largely on the specific operating conditions and design requirements. Decisions are made after considering various factors such as safety, strength, cost-effectiveness, and maintainability. Typically, during the design phase, the arrangement of reinforcement ribs is determined based on the specific application of the pressure vessel or atmospheric equipment, the loads it must withstand, design specifications, and customer requirements. In many cases, designers prefer to add reinforcement ribs on the outside to facilitate processing and future maintenance. However, each situation may have special considerations, so a comprehensive analysis should be conducted before making a final decision. .

The medium contains debris and flocculent substances that can easily get stuck; 3. It is difficult to move around when cleaning the tank

Generally, external reinforcement is used; if it’s a liquid, internal reinforcement can also be applied (such as in rectangular boxes, etc.). It depends on the situation
