Regarding the hanging ears of enamel kettles
Thread Content
The company is working on the design for a new workshop, and 12,500L and 20,000L closed-type enamel reactors are required. The design process involves determining the installation dimensions as well as the opening dimensions of these reactors. We have consulted two manufacturers of enamel reactors; one uses Type A lugs while the other uses Type B lugs. This results in significant differences in installation dimensions, and it’s difficult to determine the appropriate opening dimensions for the reactors. Choosing a larger size would be wasteful in the case of Type A lugs, while choosing a smaller size might prove insufficient if Type B lugs are ultimately used. I would like to ask everyone: which type of hanging ear is more commonly used in the reaction vessels you have come across?
Our unit has a 10,000L closed-type enamel reactor, and its supports seem to be of type B
I believe Type A earhooks are suitable for equipment without jackets and without insulation, while Type B is suitable for equipment with jackets that provide insulation or cooling. Standard number JBT4725. This post was last edited by pasttime on 2008-2-19 10:22.]
Type A lugs are used for enamel reactors that do not have insulation, while Type B lugs are used for those with insulation. The Type A lugs are shorter than those of Type B. It is also important to determine whether the enamel reactor follows standard 79 or standard 92; the sizes of the lugs for reactors under these two standards differ. Ask the equipment manufacturer to provide detailed drawings of the reactor to avoid problems such as the lugs not fitting (if the openings are too large) or the reactor not fitting inside (if the openings are too small). The thickness of the insulation layer also needs to be taken into account when considering the openings. One more thing to note: when designing, the dynamic loads associated with the installation of the enamel-lined reactor should be taken into account, to prevent the support beams from being damaged. In the past, there have been instances where the support steel channels were bent during installation.
