Jacket flange issue
Thread Content
:Loveliness: Our company is currently building a sulfur recovery facility, and the jacketed butterfly valves are required to be equipped with matching flanges. These flanges have not been supplied yet. I’ve looked up information on this in various sources as well as online, but I’m not sure what the specifications or standards for such matching flanges are For the explanation, please use the 250-1.6 clamp valve as an example. Thanks
**There are standards such as HG20592~20615 for \"Pipeline Flanges, Gaskets, and Fasteners\".
Reply to 1# daiqijun0000: The flange here is custom-made; it actually uses a blind flange that matches the flange on the jacketed valve, with an opening in the middle that corresponds to the inner tube of the jacketing tube. However, it should be noted that the flanges of jacket valves from different manufacturers may vary.
Our company is constructing a sulfur recovery unit, and the jacket butterfly valves are required to be equipped with matching flanges. These flanges have not been supplied yet; we have looked up information on this in various sources as well as online, but we are not sure what specifications or standards these matching flanges should meet For the explanation, please use the 250-1.6 clamp valve as an example. Thank you. The matching flanges are designed for a pressure of PN1.6MPa; they are raised-face, flat-welded steel jacket flanges. The outer diameter of the flanges is 405 mm, the center distance between the holes is 355 mm, and the diameter of the bolt holes is 26 mm, with 12 such holes in total. Please check whether the number of holes at the outlet of your butterfly valve matches this If it’s standard, this should be the flange. I hope this can be helpful to you! :)
