Is this pipe gallery design reasonable?
Thread Content
I saw a post saying that in order to meet the overall transportation requirements of the equipment (the equipment diameter is 17.9 meters), the cross-road design of the pipe gallery suddenly rises to a bottom elevation of more than 18 meters (about 5 to 6 stories high). Is this design reasonable? [Chemical Equipment Powerful Equipment] 500-2022 Tianjin Nangang Ethylene 17.9-meter diameter quenching oil tower https://bbs.hcbbs.com/forum.php?mod=viewthread&tid=3460609
This may not only be a matter of unreasonability, but also a deeper reason;P
In terms of project organization, it is entirely possible to reserve large transport channels and close the pipe gallery after the equipment has been transported.
If it is a renovation or expansion, this may happen. When the project was originally being constructed, we never imagined that objects with extremely large diameters would pass through today. But if it is a new project, it may be due to poor planning.
Nangang 1.2 million tons of ethylene is a new project.
It’s okay, it’s not arched :lol
That should be due to poor consideration in setting up the transportation channels for large equipment. However, if it is still under construction, the height problem of the pipe gallery should be easily solved, but the cost may be higher.
Renovation and expansion projects should also be carefully considered when encountering similar situations. Case: The Yangzi-Pakistan Integration Project also has an 11.8-meter-diameter cold water tower that needs to enter the site through the Yangzi Petrochemical Public Pipe Gallery (12.0 meters). At that time, it was considered to coordinate the transformation of the Yangzi Pipe Gallery, but it was impossible after economic analysis. The daily operating cost of Yangzi Ethylene was several million. Later, multiple plans were launched, such as: The rail + jack transportation plan, the double-crane pipe gallery straddle transportation plan on both sides, etc., after many parties brainstormed, the road was finally lowered by 60 centimeters and reinforced, and the task was completed with less money.
The transportation of large items has always been a key consideration in project construction, which is considered during the project construction planning stage. I won’t consider it until I’m on site. For external road transportation, you need to know the maximum allowable size. For large items, you must apply to the Expressway Administration Bureau. New projects within the factory area can be implemented by installing equipment first and then following the pipe corridors. Renovation and expansion projects depend on early reservations.
