I am working on a design for an odd shaped rotomolded polyethylene tank that will be filled with about 5,000 lbs of sand. I am familiar with designing tanks for liquid storage and low pressure pressure applications. However, I am not sure how to work with sand since is has more shear viscosity...

I want to perform a simulation of an air compartment (rotomolded plastic float tank) as it is pushed underwater to 75% of its buoyant capacity. The pressure on the inside stays the same, but the pressure on the outside changes as water depth increases. The submersion depth is only about 30"...

We make about 15,000 of these annually, so I am trying to reduce the amount of labor to fab the parts. We also want to use this particular bushing size because we inventory it for another use as well. I like your first suggestion of casting it with a low carbon steel. I am in the process of...

Here is a picture of what I am trying to accomplish. I want to weld the cast "eye" into the tube.

I currenly design a lot of weldments using square tubing and fabricated brackets. I would like to create some molded shapes to simplify the fabrication process. I know that welding cast iron is not feasable, but can you weld cast steel easily?? I am thinking of a similar material situation...
