Problems in large-scale equipment manufacturing
Thread Content
How can large-scale equipment sections be perfectly joined to each other, as well as to the end caps?
For large-scale equipment, vertical assembly is recommended
Vertical assembly and working at heights is very inconvenient; a pit or a platform is required
Build a platform or use the floor structure for assembly!
What are large-scale equipment? Most vertical atmospheric storage tanks are assembled on vertical foundations; pressure vessels such as air receivers and reactors are assembled on rolling tables
Vertical assembly places high demands on welders. .
When two cylinders with the same perimeter are joined together, a crane for assistance on the roller frame is sufficient; it’s very simple. With a workshop height of basically 12 meters, there is no problem in processing towers that are 30 meters long
There is an inherent ellipticity, making perfect alignment impossible; the misaligned parts are corrected using specialized equipment, such as a winch mounted on a welding fixture to align the edges properly
High requirements are placed on the equipment at the site; for example, how to assemble towers that are dozens of meters tall
Therefore, for each section, it is necessary to control the ellipticity, perimeter, and diameter, and molding tools are required
