I knew I was going to post something about bolting one day...
I have a simple line with:
- a flanged valve that use stud bolt and nuts
- another flanged valve that use cap screw
Separately calculated (I mean if I put 1 valve in a line and the other valve on another line), everything is ok. I obtain the right quantity of stud bolts, nuts and cap screw with the correct lenghts.
But if calculated in the same line the following happens:
- the description of the stud bolt is replaced by the description of the cap screw (although quantity is ok)
- the lenght of the stud bolt is wrong and is actually = to the length of the cap screw.
I am using new bolting method and have double checked all BTSE and bolting spec details...
I hope someone will figure out what could be happening.
