I realize the chemistry is the same for both products. Are there any discernible differences between these two? Our spec calls for A815 WPS31803 and our supplier says they only provide A182 F51 for products 4" and below. Why is this?
If you use a non freezing test media such as a water/glycol mixture, your min test temperature should be governed by your minimum design metal temperature (MDMT) which should be listed in your LDT. This can very greatly depending on the size of pipe, type of fitting, material, schedule, etc.
Hello - We are looking at pressure testing some pipe. It will be a heated test with the fluid heated to ~80C. It will then be introduced to the system of heavy walled, #1500 carbon steel pipe that may have cold spots on exterior sections as low as -25C. I feel like the temperature differential...
Looking for ideas or tips on this subject. I thought maybe a tubular chain conveyor would be applicable in this case.
Does anyone here have any experience with these types of conveyors? How is the reliability, preventive maintenance and standard maintenance on these?

Thank you for the reply.
The thickness of the mold is three inches, everywhere. I don't see how the material is relevant, I'm just looking for the internal stress at the middle of the top lip section. This will be the same for any material. Also, disregard the temperature, assume it is room...
Hello
I am trying to figure out the effect of stacking molds of hot liquid material on top of other molds.
I know there needs to be a moment analysis but my statics knowledge has been lost.
We are seeing cracks develop in the center of the molds and I'm looking to see what is the actual...
