Following a piping code B31.3. "A pipe having a branch connection is weakened by the opening that must be made in it, unless the wall thickness of the pipe is sufficiently in excess of that required to sustain the pressure, it is necessary to provide added reinforcement".
Does that mean that...
Thanks a lot, actually I took the option to design 3 loops instead of 2 along the rack.That way I reduced the restraint at 25000N (axial force)wich seems more reasonnable for me in term of stability of the line.
I agree with DSB123, instead of anchors block directions x,y,z on each side of the loop. This will result with only restraints in these directions with no moment. The loop should be also guided on each side (between the loop and the anchor).
Iam working on the flexibility of a steam line going from an existing manifold(Ti-in)to a steam turbine. Here are the calculation conditions: 490°C(about 900°F); 3Mpa; Pipe: 12" thk:0,885".
This line runs along a rack, I designed some loops (2 loops) to improved the flexibility. I guided and...
Hello,
does anyone know where i can find the grinnel's book:
"Piping Design & Engineering" ? is it still available?,
thank you in advance for your help.
hi,
I would like to know if it exist criteria to select lines to be calculated (flexibility analysis). Does the PED require calculation notes on cathegory III?. It's not clear for me.
thank you ,

does anyone know if the ASME B31.1 is in accordance with the PED. I know that a guide has been released by the CEN (europan normalization) to help the use of the B31.3 in europe, but what about the B31.1?.
