[0002] Liquefied gas pipeline refers to the trunk pipeline for transporting liquefied petroleum gas and liquefied natural gas. Measures must be taken to prevent liquefied natural gas from vaporizing during pipeline transportation, including: the liquefied gas pipeline should have a good insulation layer, the pressure during liquefied gas transportation, etc. Among them, PIR cold insulation pipe has the advantages of small thermal conductivity, light weight and shock resistance, strong adaptability, etc., to ensure the stable transportation of liquefied gas.

[0003] However, it still has the following disadvantages in actual use:

[0004] The existing PIR cold insulation tubes that are easy to transport are placed and transported in a simple cross-stacked manner during use. However, due to the lack of corresponding limiting measures, this method is prone to uneven force during transportation, which may cause damage to the cold insulation tubes and has poor stability.
