[0002] Hairpin heat exchangers are dual-loop, compact, and suitable for high-temperature and high-pressure applications. Large hairpin heat exchangers, especially those with a diameter of DN≥1500, are widely used in various industrial sectors due to their unique structure and performance advantages.
[0003] Large hairpin heat exchangers are large in size and heavy in weight, making it difficult to set up packaging structures. Due to their large tonnage and extra-long and extra-wide dimensions, they face multiple challenges during transportation without being modularized and disassembled.
[0004] Heat exchangers are typically transported horizontally. However, the sliding supports of the equipment body should be located near the large bend in the shell, and this part of the transport packaging structure also needs to be close to the large bend in the shell. This leads to a technical problem during transportation: the sliding supports of the packaging structure and the equipment body can easily interfere with each other, affecting transportation efficiency.
