Well it turns out that the Expert that I thought I found thinks that it is out of his area of expertise. I am really needing help here so if anyone is interested or knows someone who might want to consult on this I would really like to find someone.
I am going to go back to crunching numbers...
Sorry for disapearing. My plant had a major explosion and I have spent the last month and a half helping to rebuild it. We have just made our first pipe today so things, hopefully, will slowly return to normal. Needless to say this suddenly became a low priority for the plant. I have also...
crystal1clear,
Yes there is 3 pipe, on smaller sizes, on 4 axles. The outside axles are idlers so they are independant. We do not have any problem with the tires slipping. The tires are replaced as a tandem or an entire axle.
CapriRacer,
This is a brand-new piece of equipment. The old...
CapriRacer,
To answer a couple of your questions:
We were running unloaded pressure of 70psi we have since changed it to 45psi.
All of the tires are within 6 wks old when they blow, and we are changing at least both tires in a tandem, most of the time we are changing all 4 tires on an axle as we...

There are 4 axles with the two inside axles being drivers and the outside two are idlers. I agree that the load will not be the same for all of the tires. The pipe has a bell on it that is considerably larger, thicker and heavier. There seems to be no pattern to the chunking. I am...
Thanks everyone for your input. I've had some local "experts" come and look and what they have said is that with higher air pressures there is no 'give' in the sidewalls and so the tread is taking all of the flex, they also said that the tire is slightly narrower than what the rim is made for...
I have a "High Spin" rolling system that spins pipe to compact cement lining. We are using tandem 7-14.5LT D/8 bias-ply tires on each end of the axles with the pipe riding in the saddle between two sets of tires. The tires are running approx. 70 MPH for just over a min. The maximum weight of...
Byucougar, I am wondering are you in Utah? If so you might want to contact Pacific States Cast Iron Pipe Co. in Provo, UT someone here could probably would be able to help you with your questions as we use nitrogen in our iron melting process. http://www.pscipco.com/ . I am a maintenance...
