Hello guys, I am working on converting a bulk storage heavy oil tank into a bitumen bulk storage tank. This is a big vertical API650 tank O.D. 25m x 12.5m height. Our company uses holding tanks for pumping at usable temperature for the end users with blends and additives and insulates mainly...

Hello Axle, Thank you so much for replying. I can't believe the picture, would never have imagined that big an anchor block, can understand that pipe size but that block is huge. I feel really dwarfed in the industry to be honest in these early stages of the career. Find points along the pipe...

Hello ax1e, Thank you so much for your detailed input. To be honest I learnt a lot from your first post to avoid huge loads on the anchors and try alternatives instead of being lazy and accepting results. Thank you for that. Pardon my expansion numbers, your numbers are correct. My number for...

HTURKAK, Thank you for the explanation of the low point pocket. And sorry for not describing the heating and insulation properly. The scope of work specified to me requires the whole line to be heated during operation. I have been insisted on using thermal oil lines inside the process pipeline...

Please have a look at the additional files posted from the expansion loop method in the pipe stress analysis software in the original post.

Hello MJCronin, Thank you for the link. My first search was double containment systems and I did go to PERMA-PIPE. I looked at the same pdf and due to the legal requirements I cannot use a PVC encasing pipe anymore, that was the initial idea to use PVC PN16 or something but it doesn't qualify...

Hello HTURKAK, Yes, I will try one iteration without the bellows and see how bad it goes. I was so much focused on the thermal expansion catering and my space limitations that I didn't think of a novel solution with just pipe routing. I will play around today and come up with a loop system...

Hello LittleInch, Yes, the process line is inside the tunnel supported on spider supports and hence centralised. It has a rockwool insulation and heat tracing. My client wants to use thermal oil heating and the pipe has to be inside the process line. Bit tricky for me. Yes, I did notice...

Thank you so much everyone for your replies, this was my first thread didn't expect replies for days. This indeed is a great site.

Hello, I am a mechanical engineer working now as a project engineer to handle design and commissioning of heated bitumen lines as I work in the bitumen industry. My most recent project is design of a buried bitumen line extending only for 100 m ( my research online shows that this distance is...
