How to properly insulate the lifting lugs at the top of a distillation tower
Thread Content
Dear friends: Insulation around the lifting lugs at the top of the distillation tower never seems to be done properly, as it is often blown away by the wind. Could you please share some ideas on how to ensure proper insulation for those lifting lugs? Thank you!
It’s best to send a video; it’s more intuitive to convey things through images. I’ve tried to come up with a method; I’m not sure if it will work, but it’s just for reference. Is it allowed to insert a bolt at the center of the lifting lug’s cross-section (the bolt can be welded in place or drilled using a down-the-hole drill), then fit a section of pipe over the lifting lug, fill the space inside with insulation material, and finally use a circular steel plate larger than the outer diameter of the cylindrical tube; a hole is made in the middle of this plate, which is then placed over the insulated cylinder and secured with bolts. This allows for insulation of the entire trunnion at once. Insulation materials can be filled with foam agents, or they can be made of glass wool and other insulating materials.
Are there any standards or photos of successful cases?

The equipment manufacturer should have an explanation for the frequent problems. I retired from a counterfeit-related company; the solutions I provide are for reference only. In terms of standards, coordination among enterprises is the most reliable approach. For reference. Oh, if you need to solve it on your own, it’s best to send a video along with the approximate specifications; that might help as a reference.
The method used on the second floor could be used as a reference ============================== In fact, it’s sufficient to simply create a thermal insulation box using iron sheet; this box needs to be secured with straps. It’s best to use galvanized iron sheet, as it is stronger
It is rare to see requests for insulation on lifting lugs
I just happened to be around, so I got involved; P
It can never be done well; the time is blown away by the wind. In fact, this is the real problem

Work inertia – leaving some surplus energy to give back to the forum. I remember how I shifted from the chemical industry to project construction and then to metallurgical machinery, and inadvertently became a ‘guerrilla’ – every step of the way I relied on the information shared on this forum :)
With this method, not even the strongest winds can blow it away; it’s worth giving it a try. :)
