Looper flange type and sealing
Thread Content
This post was last edited by Taizhou Yijia on 2017-3-24 at 16:05. I would like to ask how the swivel flange is sealed, as shown in the picture. Part number 1 is a pipe flange DN40(B)-10 RF with a pipe diameter of 45; part number 2 is a swivel flange DN65(B)-10 RF. Part number 3 is also a pipe flange DN65(B)-10 RF with a pipe diameter of 76. How is the seal between the swivel flange (part number 2) and the pipe flange (part number 23) achieved?
It involves welding a pipe fitting through an opening in the flange; part number 2 refers to a flange with such an opening, which is sealed against the flange by gaskets.
Item No. 2 is not welded, it’s for the promotion
Your size 2 isn’t a live-end flange at all; it’s just a flange with an opening in it. Take a look for yourself in GB150 to see what constitutes a loop flange.
The slip flange I drew is just for illustration purposes
That’s impossible, how can it be sealed?
Seal the space between sizes 2 and 3 with gaskets; it’s the diameters of the two flanges that are sealed using gaskets.
Sealing with gaskets is more complicated than using ordinary methods
Is the Φ45 fitting not welded to part number 2?
By \"trouble,\" I mean that it’s not easy to install the gaskets; in other words, it takes more time
