Make (closing) with high temperature resistant sewing thread on one side around the reusable thermal insulation quilt of the present utility model or arbitrarily, also can according to need around the product or any limit be sewn into the shape (comprising irregularly shaped) that needs with high temperature resistant sewing thread.
Product of the present utility model compared with prior art has the following advantages:
1, simple in structure, to install, dismounting is very convenient, work efficiency improves tens of times;
2, long service life can reach more than 10 years;
3, the detachable repeated use.For the equipment of the frequent partial disassembly of needs maintenance, not only maintenance is convenient, and can save cost greatly;
4, alleviate labor strength;
5, improve site environment, prevent the fibre dust that produces in the work progresss such as rock wool, mineral wool, the protection workers ' health;
6, high insulating effect, external shape and temperature requirement that can be different according to steam turbine, and design the insulating product of different thickness, different material, different shape, the different number of plies, satisfy technological requirement to greatest extent, and obtain optimum performance price ratio;
7, do not need drying process, save construction period greatly;
