Thanks for the document and info.....note that we are already using NEW method and I believe I was not able to explain the problem well....everything is working fine but the problem is getting exact bolt lengths when using different ratings flanges in one spec.
Example...lets say you have the following flanges in one spec
Now all these flanges use the same bolt diameter of 1/2" BUT different bolt lengths....
With the new bolting method, the system will pick up the first bolt with Bdia 1/2" in the spec and use its SBOL for extra length calculation and all
Though the flange thickness will be different for different ratings but as the system will only use the first available 1/2" bolt in the spec so the extra length will be used for that...now if we use the extra length for #150RF, it may give incorrect lengths for 300 and 600 and vice versa...
so to overcome this...we put an intermediate extra length and try to satisfy all conditions (three or more ratings)..most of the values can be satisfied but still some DN sizes cannot have exact values coz satisfying one rating can disturb the others...
so coming back to my question. is there a way that PDMS can select bolts from spec based on Rating and Bdia instead of just bolt dia???
