How To Choose The Best Carbon Steel Weld Flanges For Your Project?
There are many different types of carbon steel flanges, and they can be used for completely variou purposes. Here are some examples
- Blind flange : BLRF flange used to close off the ends of pressure vessels
- Slip-on flange : In SORF flanges case the pipe is not butt welded, but goes inner side the flange
- Weld neck flange : WNRF flange have a long neck of the same diameter as the pipe
- Socket weld flange : SWRF flanges have a pipe that goes into the flange with the same internal diameter (I.D.) as the pipe
