pipe flange thickness
(OP)
Hi,
I want to make a drawing for pipe flange. Details as follows:
Size: DN2600
Pressure: PN16 Bar (FOS included)
Material: Mild steel
Doubt: What thickness I need to give for this flange? Since this is a very big size, most of the standards have not mentioned about the thickness value.
But AWWA C207 Class E has mentioned the thickness as 5.5". Is this correct to use? Please find the attachment.
(Note: Regarding flange drilling details, I can refer to the valve drawing)
Pleas suggest with your experiences.

RE: pipe flange thickness
5.5" thick?? WOW. And 72, 2.5" diam bolts (!!!) You might need two men to lift them into position.
Just make sure you follow all the requirements of the AWWA code for this size flange.
Remember - More details = better answers
Also: If you get a response it's polite to respond to it.
RE: pipe flange thickness
I'm going to maintain pipe flange drilling as per the valve flange drilling.
My concern is only about thickness.
5.5" is more or is it okay?

RE: pipe flange thickness
Refer ASME BPVC UG-34 or there about for a method of calculation required flange thickness.
The other sanity check is the make it at the same thickness as the valve flange (I'm assuming the valve is flanged, if it isn't ignore this comment)

RE: pipe flange thickness
Thanks for your post.
Yes. The valve is flanged. But it is ductile iron material(min. Yield strength is 320 Mpa). Where as my pipe Flange is mild steel ( Yield strength is 250mpa).
Because of lower yield strength of pipe Flange, I think it is not recommended to maintain same as valve flange thickness. Pls comment your views on this.
