Interference between the connecting tube and the saddle pad
Thread Content
The design of a horizontal container did not take into account the widening of the backing plate after the saddle standard was updated, and the drawing was still based on the 92 version of the saddle standard. As a result, no interference between the pipe and the saddle backing plate was found. Please give advice on how to deal with it.
Then the stress should be checked according to the 92 version of the saddle. If it is qualified, it is still feasible, and then a gap will be made in the backing plate to avoid the nozzle.
If there is no opening, just try to move it away.
Check whether the movement of the connection will affect the process and on-site piping. If not, it is best to move it to avoid the backing plate.
The new standard allows you to modify the width of the backing plate. In other words, you can use the width of the backing plate in the old standard, as long as you indicate the dimensions on the drawing.
It's best to move the saddle. If the basic drawing has been decided, consider adding a base plate under the saddle.
It is best to move the pipe. If the pipe touches the backing plate, it is likely that it will touch the foundation during future piping.
The simplest thing is to move the pipe appropriately, which should not affect the on-site piping.
If the width is sufficient, the saddle pad can be used as a connecting reinforcing ring.
Then don't adopt the new standard saddle. The general calculation of the design according to the old standards can also pass. You can do it according to the old standards, design it as a non-standard support, and just draw a separate detailed drawing of the saddle on the drawing.
The first option is to change the takeover position, the second option is to use the old standard pad, and mark it on the drawing after passing the verification. The last option is to make holes in the pad, and there must be changes in the design documents.
Just move the takeover out of the way of the saddle. After all, the position of the takeover is not fixed, and the saddle needs to bear the pressure.
Please ask a chemical process professional to see if the position of the nozzle can be moved? It is best not to change the position of the saddle. The force on the saddle is very complicated! If it can be analyzed by ANSYS, it can be moved!
Let's take over and move it. Compared with other problems, it is relatively easy to take over the changed piping.
Agree with the second floor's opinion. Make a gap in the backing plate to avoid the connection. The gap should be smooth.
It is best to move the nozzle. If the nozzle cannot be moved, you can open a gap in the backing plate to avoid it.
Changing the takeover position is generally not difficult or difficult.
