Hello,
I was wondering if anyone knows of any concrete requirements to certification requirements for mechanical handling equipment that is of foldable or of collapsable designs.
For instance, do I need to re-certify an A-Frame Gantry if I take it down after I reassemble it? Same would go...
Ron my bad I thought it was from pressure to torque. Yes the equation you reffered to holds assuming the same conditions I have given. This is however an aproximation. The full equation is given in ASME PCC-1, and takes into account much more parameters.
Generally, for any material, the torque needed is directly related to the bolt size. The torque function is exponential. For 5/8" and 3/4" diameter, your torque would need to be:
18 and 36 ft-lb for 20 ksi
27 and 56 ft-lb for 30 ksi
ASSUMING:
-A coefficient of friction of around 0.12...
Ripz, the pipes will be radiographed as well. The overlay is because this is a highly corrosive environment.
wegm, the welding is actually internally performed, so this means I should start with the 316 root weld? As for the working temperature, it is 100 degC so I wouldn't worry about the...
Oh sorry the header is NPS 8", and the tee is NPS 6". I do have several welds to do though, that's just one of them. What do you recommend for optimizing in general?
Hey guys,
I have an ASTM A333 Gr. 6, seamless, with 3mm SS 316/316L overlay pipe to be welded to an ASTM A403 WP 316/316L reducer tee. Now as per my understanding, I shouldn't face any problems welding the two metals together. However, what would be a proposed methodology? And what filler metal...
