Piping issues

Firstly, to prevent fluid accumulation, the elevation of the smaller pipes is set higher than that of the larger pipes below them. Secondly, the bypass is used in emergency situations or during maintenance. . .

1. Some of the bends are designed with stress factors in mind; it’s hard to see clearly from the pictures. 2. Since the bypass is not used frequently, it’s only employed during maintenance or when there are problems with the main pipeline, so factors such as pressure loss and flow rate are not taken into account. Reducing the diameter can help save on costs.

Something was said about the 2nd and 3rd floors, but it’s not very accurate. 1. I don’t know what medium is flowing in your pipes nor their direction of flow, but the standard requirement for gas pipe openings is that they should face upward; this approach can be considered the most reasonable arrangement ； Of course, a sliding door is also an option; it’s completely fine to change it to what you mentioned. 2. This issue needs to be discussed separately. Normally, a flow meter used for settlement should not have a bypass; however, considering maintenance and process requirements, one can still install such a bypass. The reduction in diameter is generally done because the bypass is meant as a backup and is used very rarely, and reducing the diameter helps save costs. It’s also fine if no diameter reduction is made. The bypass system for valves is another matter; large valves all come equipped with bypasses, and these bypasses have a small diameter. This is because it is very difficult to open large valves due to pressure differences, and in such cases the bypass is used to equalize the pressure on both sides, allowing the valve to be opened more easily.

Question 1: It’s not very clear from the image, but a 90° elbow can be directly connected to the tee, which only increases the length of the hanger. It’s possible it’s due to the medium. Second question: The size of a flow meter is determined based on factors such as flow rate, fluid type, operating temperature, and pressure. Its diameter is generally smaller than the diameter required by the process; to reduce the flow velocity and facilitate connection, reducers need to be installed at its inlet and outlet.

Firstly, to prevent fluid accumulation, the elevation of the smaller pipes is set higher than that of the larger pipes below them. Secondly, the bypass is used in emergency situations or during maintenance. . . I completely agree with what was said on the 2nd floor; it makes sense. I’ve also learned *that

Since the diagram is not visible, I will provide an answer based on my understanding: A bypass valve is typically used temporarily during maintenance or when there are faults with control valves (including pneumatic, electric, or self-acting types). Its function is to act as a substitute for such control valves for a short period of time. Therefore, the diameter of the bypass valve is usually the same as that of the control valve, which facilitates manual control of flow by operators. The correct size for an automatically controlled valve should be smaller than the diameter of the pipes it is connected to,; thus, the diameter of the bypass valve must also be smaller than that of the pipes, which is equivalent to a reduction in diameter...
