Leg length calculation (Expansion Case)

hi again,


do anybody have an idea about How the leg length can be calculated???

i have FLUOR manual in that they have calculated leg length, however i didn't get that.

e.g. Pipes connected between two anchor. 6" SCH 40 @ 300 degree F N material is CS. having horizontal length 25'(guide)+ 25'+20' and vertical length = 20'
Vertical Expansion is =20 * 0.0182 = 0.364"


hence Calculated leg Length is (L) =20+25+5= 50'
and Thermal Force(T.F.) = Less than 200#

Now how that L and T.F has been calculated ????




thx in advance.

hi Friendz,


i am waiting.

Hi,


coade people plzzz??

You can find the "guided cantilever method" in texts on the subject of Pipe Stress and Flexibility Analysis. The explantion is not something I can put here in the Forum, or even in an e-mail. Ask someone at your location for help on this.

hi,

Thx for guidance. i got the calculations.

Hi pramod,

Can you give that calc to forum people , so it will be good to learn
