Calculation of the reinforcement ring diameter
Thread Content
For the openings in DN700, what diameter should be used for the reinforcement ring when estimating the reinforcement area?
In accordance with the requirements of GB50-1998 standard, the reinforcement area is calculated; once the reinforcement area is determined, the width of the reinforcement ring is calculated based on the specifications of the fitting.
JB/T4736-2002 Reinforcing Ring
Opening reinforcement calculations on Gb150
The estimate is generally on the lower side, at 2 times the diameter of the pipe, while it is usually on the higher side at 1.6 times the diameter of the pipe. DN700 is roughly 1.6 times that, right!
Don’t you have SW6? You can directly calculate the opening reinforcement using SW6! !
The outer diameter of the large reinforcement ring must not exceed 2 times the outer diameter of the pipe fitting.
Please refer to the relevant content on reinforcing rings in JB/T4736-2002.
I also want to know what the outer diameter of the reinforcement rings for DN700, DN800, and even DN2000 can be set to; the JB/T4736-2002 standard specifies a maximum pore diameter of DN600.
Just pick one arbitrarily; as long as it can be calculated using SW6, that should be fine. A view is not necessarily correct.

The reinforcement of dn700 can be carried out using thick-walled pipes; the calculation methods for reinforcement are the same as those used for such pipes. Reinforcement rings need to be manufactured and welded, and air-tightness testing is also required – why go through all that trouble? For specifications that aren’t covered by standards, it’s not recommended to use a reinforcement ring structure
