Could everyone please introduce the hook loops in heat exchangers?
Thread Content
I’m not familiar with this; thanks to everyone!
Hook loops are generally used in the tail floating head structure of floating-head heat exchangers to secure the floating tube sheet; they can be basically divided into two types, a and b. For their specific design, reference can be made to GB151 \"Shell and Tube Heat Exchangers\" or related books.
GB151 provides detailed structural diagrams of hook loops along with brief introductions to them; the original poster can learn more from it
A crochet loop is actually two half-rings; this is included in the standards mentioned by those above. However, it’s best to find an experienced person who can explain it to you – once they do, you’ll understand
Yes, the hook ring is a relatively important component of the heat exchanger; Section 151 provides a description of its structure as well as methods for calculating its dimensional specifications. There are two types, A and B; the main difference lies in the thickness of the hook at that position.
Now it’s completely clear, haha, thanks!
A crochet hook is actually two half-rings; you’ll understand as soon as you look at a set of instructions
Special components for floating-head heat exchangers, available in types A and B; type B is more widely used (as it saves material).
It is described in GB151; there are two types
