Hi Habib,
thanks for your reply
i want to analysis for a steam line of 170m straight pipe with 180 deg c with 14 bar pressure.one end is fixed which comes from engine room other end is allowed to move 330mm as per expansion. but now what is the problem is site not required the expansion of 330mm and they have only one flanged spool in mid of line.so they want to introduce a bellow over there.We want to put a new bellow.first i tried with untied bellow and i get a anchor point load of 20 tons. for reducing anchor point load i reduce the axial stiffness value.is this is correct method.
regards
Ramesh G
