Cooling Pipe: Need Options for 45° Temp Drop

AI Thread Summary
To achieve a 45° temperature drop in a pipe that must remain at 5 degrees below the external temperature, options include using materials with high thermal conductivity or placing the pipe in contact with cooling elements like blocks of ice. The discussion emphasizes the need for external cooling methods, as altering the pipe itself is not an option. Suggestions may involve innovative insulation techniques or utilizing phase change materials to absorb heat. The focus remains on passive cooling solutions that can effectively lower the pipe's temperature without altering its structure. Effective cooling strategies are essential for maintaining the desired temperature within the constraints provided.

I have a pipe that needs to be 5 degrees below the external temperature outside(eg- 45 degrees outside means 40 degrees within). I cannot remove the pipe or anything, all I can change is the what the pipe passes through, for example if it passes a block of ice then technically the pipe would cool also. So basically do you guys have any suggestions for what I can use to cool the pipe(also no sending anything through it besides air.

I would appreciate any suggestions.
Thank You,

Thread 'Cantilever help'

I'm trying to decide what size and type of galvanized steel I need for 2 cantilever extensions. The cantilever is 5 ft. The space between the two cantilever arms is a 17 ft Gap the center 7 ft of the 17 ft Gap we'll need to Bear approximately 17,000 lb spread evenly from the front of the cantilever to the back of the cantilever over 5 ft. I will put support beams across these cantilever arms to support the load evenly

Thread 'What's the most likely cause for this carbon seal crack?'

We have a molded carbon graphite seal that is used in an inline axial piston, variable displacement hydraulic pump. One of our customers reported that, when using the “A” parts in the past, they only needed to replace them due to normal wear. However, after switching to our parts, the replacement cycle seems to be much shorter due to “broken” or “cracked” failures. This issue was identified after hydraulic fluid leakage was observed. According to their records, the same problem has occurred...
