Installation of 8 ear-type supported pressure vessels
Thread Content
There is currently one medium-pressure reactor with a diameter of 3800 mm and a weight of 67 t (which has already undergone full heat treatment), equipped with 8 lug supports. For ease of transportation, the two symmetrical ear brackets are removed and reinstalled after the equipment is in place. At the same time, the supporting structure consists of anchor screws embedded in four concrete beams; the additional 4 supports are placed on the steel crossbeams at the four corners of the concrete frame, forming a Bagua-beam configuration. Question: How to align this device? Currently, shims are placed at the 4 concrete footings and then alignment is carried out, but how can it be ensured that the other 4 ear-type supports mounted on the steel beams fit together tightly? ? ?
Pay attention to it. The more there is, the harder it is to maintain a single plane. The equipment is too heavy; can’t four be used? Are there other considerations?
Of course, it’s other considerations! It seems that, aside from acceptance standards and specifications, forums and the internet don’t cover anything related to the installation process at all! Where should I look for relevant knowledge on this topic?
Whether it is a concrete foundation or a steel frame, a relative elevation can be determined; once the elevation is known, it should be easier to level the surface.
Eight lugs, in two layers. It is easy to ensure even stress distribution on the four ear mounts in the same layer, but it is very difficult to achieve even stress distribution across ear mounts in different layers. We have also made two-layer ear rests, with one layer designed to bear weight and the other serving a guiding function (without bearing weight).
