[0023] Furthermore, the multiple heat preservation and heat insulation bottom covers 1 can be fixed to each other through the positioning seat 7, the fifth threaded hole 701, the positioning rotating plate 8, the sixth threaded hole 801 and a screw, so as to adjust the overall use length of the heat preservation cover.

[0024] During the use process, the following steps are carried out:

[0025] Step 1, according to the length of the steel cylinder, use the corresponding number of heat preservation and heat insulation bottom covers 1 and heat preservation and heat insulation top covers 2, and fix each adjacent two heat preservation and heat insulation bottom covers 1 to each other through the positioning seat 7, the fifth threaded hole 701, the positioning rotating plate 8, the sixth threaded hole 801 and a screw, so as to adjust the use length of the heat preservation cover to a state adapted to the length of the steel cylinder;
