I can speak fluent drunkenese so I will translate........"glug glug glug cough glug glug glug glug"

I have devised and fabricated some templates for pipe saddles on a nuclear facility (near you). We are now in full production of the saddles after earthquake testing and will be shipping them out for installation at every facility worldwide to meet demand for earthquake proofing after the incident in Japan.

Simple ........could you guys not read that?? Sheesh.

no I wasn't jackedup computor crashed while i was writing post. prior to rolling mild steel1/2 sections
3/8 thick customer has asked for verification of e to e measreurment,. sapparently several 1/2 shell sect
at job site were found to be 1/4 " short. these were parts weret triple checked prior to rolling . these parts were
rolleed to same radius so why would they come up different dimensions iM thinking that the roll operator applied
more pressure during rolling that woiuld make the material compress more and beco0me thinner and longer.
any other sugbgestions. customer wants fabricator to roll long then re cut to desired dimnension twice the work
rolling was not covered any traing . thanks Joe

I don't think more pressure on you roll will make it shorter. When the fabricator figured his cut length did he figure the length along the inside of the radius or over the outside because the outside will be longer because the thickness of the plate will add to the radius of the roll.

the problem is that after rolling the flat plate plate pieces which were all cut too the same length
do not have the same overall dimension after rolling. there are 4 shells that make up a unit., these
shells go around an existing concrfete column . 2 bottom pieces then 2 top pieces stacked on top
the shells need to be the exact same size so the weld seams will align vertically. it wouldnt matter if
the outside dia changes just a little bit as their is 1 1/2 space between existing concrete and new steel
for grout. The field inspector is not allowing any deviation on the root openings. the root opening can be
1/4" to 3/4" . If the bottom shells are fit with a 3/8 opening he wants the top shells to have the same opening
when one shell is shorter after rolling getting this to align perfectly is impossible. They are currently field
trimming the shell sections to transition so the root opeming is the same at the point of initial contact.
no one casn figure out why length is changing during the rolling operation any ideas ?

If they are shearing prior to rolling, are they checking to make sure they shear square? I've had guys measure end to end and not be square corner to corner and the roll seam will be off. We generally CNC cut the entire sheet if possible so all is straight and square. Now that you have me thinking about it, I recall a job on some vessels we built where my material came in from two different mills. Both were A36 however one batch from one mill rolled correct according to my calculations but the batch from the other mill every roll was slightly different. I think something was off with the material and it reacted different .
