Selection of heat exchanger tie rods

2020-10-12View Original

Thread Content

We are now designing a fixed-tube-sheet heat exchanger, with heat exchange tubes of specification φ76x3. GB/T 151 does not specify the diameter of the tie rods corresponding to this tube specification. I would like to ask everyone: 1. What should be the appropriate diameter for the tie rods? 2. What specification is suitable for the spacing tube? 3. Is it reasonable to choose 12 tie rods? 4. Once the diameter of the selected tie rod is determined, how is the depth of the tie rod hole determined? (If the rod diameter is greater than the rod diameter specified in GB/T 151)

There’s something called a stretch tube… a tube that can be used directly

Additionally, the number of tie rods is determined based on the supporting area

See GB/T151-2014, clause 6.8.5.2

The selection of the tie rod diameter is related to the diameter of the heat exchanger, as well as the specifications and quantity of the heat exchange tubes.

The selection of the tie rod diameter is related to the diameter of the heat exchanger, as well as the specifications and quantity of the heat exchange tubes. If it exceeds the 151 limit, appropriate enlargement can be applied.

Is there no calculation for the tie rod in 151?
