Regarding the thickness limit of the reinforcement ring
Thread Content
Why is the maximum thickness of the reinforcement ring specified as 30 mm in Table 1 of the JB/T4736-2002 standard for \"Reinforcement Rings\"? What should be done if, in the calculations for reinforcement through openings, the thickness of the reinforcement ring needs to be greater than 30 mm?
It can be changed to a thick-walled tube reinforcement structure.

In other words, the reinforcement effect is limited – it’s not effective across the entire area. If the ring is too thick, it won’t fit tightly. For thick-walled pipes, use methods such as internal extension, trying to reduce the diameter of the openings, as well as techniques like end caps, flanging, and embedding… :lol:lol, that’s just nonsense
Thick-walled pipes with reinforcing rings are used...
