Hi Jozm,

I understand your point to claculate expansion value based on metal temp. & corrosponding coefficient of thermal expansion. But my query is that whether is there any rule suggesting maximum expansion value that the loop can aborb.

Also I found in flour pipe stress design guide that in cahnge in direction of pipe the maximium allowed thermal expansion is 5 inch. It also suggested that for expansion loop, the thermal expansion going into the loop shoud be limited to 12 inch.

Wheter have you come across such articles or facts?

Thanks mate.
