New France has a hole
Thread Content
The new flange has a hole, but it is not connected to the medium – what is its purpose?
The holes in the flange through which bolts pass are not in contact with the medium – what’s strange about that?
I’m really at a loss for words:funk: But, Mr. Qu, you have several holes here, not just one. Another option is to connect it at the RTJ washer location.
One of several options: it is not connected to any medium; it usually has only bolt holes, and perhaps a small hole for a tag or wire to pass through. People who can’t even figure out how to upload a picture have generally not very good brains.
It is also possible to place a small screw between the two bolt holes, to use it for pushing the flange apart when removing it. The pictures might have been lost when uploaded from the phone. . . Maybe he thought he had made himself clear. . .
I’m sorry, I don’t have any images at the moment. A colleague told me that there is a hole on the side of the flange at the outlet of the heat exchanger; it’s about the size of a 422 welding rod. The hole is quite deep but not connected to anything. I’d like to know what purpose it serves or whether it was designed by the manufacturer
