The two insulation half rings 2 are opposite to each other and the ends of the two insulation half rings 2 abut against each other. The two insulation half rings 2 form a circular ring shape and completely cover the arc-shaped outer wall of the pipeline body 1.
[0034] The heat-insulating half ring 2 comprises a heat-insulating layer 21 and two protective layers 22 , and the heat-insulating layer 21 is fixedly connected between the two protective layers 22 .
[0035] In this embodiment, the insulation layer 21 is made of phase change material, wherein the insulation layer 21 includes a working pipe, polyurethane, and a polyethylene outer protective layer, which are sequentially sleeved from the inside to the outside, and the three are integrally formed and bonded together by polyurethane foaming. The insulation layer 21 is filled with fillers composed of steelmaking waste slag or metals. The protective layer 22 is made of stainless steel.
[0036] A sealing block 4 is provided at the abutment of the upper ends of the two heat-insulating half rings 2, and the sealing block 4 is arranged in a direction parallel to the axis of the heat-insulating half rings 2. A mounting groove 5 is provided at the heat-insulating half ring 2 opposite to the sealing block 4, and the mounting groove 5 is arranged in a direction parallel to the axis of the heat-insulating half ring 2. The sealing block 4 is placed in the mounting groove 5 and matched with the mounting groove 5. The sealing block 4 completely blocks the abutment of the two heat-insulating half rings 2, and a fixing component 3 for fixing the sealing block 4 on the two heat-insulating half rings 2 is provided on the sealing block 4.
[0037] The fixing assembly 3 includes a plurality of fixing bolts 31, which are arranged in two rows, and each row of fixing bolts 31 is arranged equidistantly along the length direction of the sealing block 4. The rod of the fixing bolt 31 passes through the sealing block 4 and is threadedly connected to the protective layer 22 in the insulation half ring 2.
[0038] Thus, by rotating the fixing bolt 31 , the rod of the fixing bolt 31 can be separated from the protective layer 22 , thereby canceling the fixation of the sealing block 4 in the mounting groove 5 and canceling the fixation between the two thermal insulation half rings 2 .
[0039] Water stop grooves 6 are provided on both sides of the bottom of the installation groove 5, and the water stop grooves 6 are arranged along the length direction of the insulation half ring 2.

Two adjacent water absorbing cottons are fixedly connected, and the water absorbing cotton close to one side of the rubber sealing plug 81 is fixedly connected to the rubber sealing plug 81.
[0044] The implementation principle of the embodiment of the present application, which is an overhead steam insulated pipeline that is easy to transport, is as follows: when the insulated pipeline needs to be transported, the fixing bolts 31 can be rotated to cancel the fixing of the two insulation half rings 2 by the sealing block 4, so that the two insulation half rings 2 are detached from the pipeline body 1, and the pipeline body 1 and the insulation half rings 2 can be transported separately.
