Sengna Posted January 9, 2015 Share Posted January 9, 2015 Hi, Simple question, I tried to draw long 48" steel pipe sweep in autocad, i could not find any reference sheet for standard size for long pipe sweep. Does anyone have any to share for ref, do i just draw a quarter of circle with R of 48" and offset 4" each side?? Just want to make sure i did it right. Thanks Pipe Dia is 8" R is 48" Quote Link to comment Share on other sites More sharing options...
gazza_au Posted January 12, 2015 Share Posted January 12, 2015 1 or 1.5 x D thats for standard bends, you can have anything up to 6 x D, there is info out there e,g http://www.shurjoint.com/eng/files/product/E-17_L90-3D_5D_6D_Elbow-revM.pdf what your doing is fine, then offset again for the wall thickness and trim.

nukecad Posted January 13, 2015 Share Posted January 13, 2015 Remember of course that 8" is just the nominal size of the pipe. This is Ok for diagrams but if you are going to make any bespoke support brackets, etc. or need a hole through a wall then you need to find the actual pipe O/Dia. As you are in the USA I asume you are using ANSI / ASME standards so the following chart may help. http://www.engineersedge.com/pipe_schedules.htm You will see from that that an 8" nominial pipe is actually 8.625" O/Dia.

Yes Nukecad, I should use ANSI, i should use the Actual pipe OD at all time. I will print out the sheet you provide, they are very good info. Thanks alot Quote Link to comment Share on other sites More sharing options...
