shall be the bandwidth. (5) filling method construction 1. The filling method. Filled with granular or batt insulation materials to the outside of the equipment and pipe wall inside the cavity of the construction method. The method under the condition of lack of adiabatic products use, also suitable for special-shaped pipe fittings made coat internal filling. 2. The filling method thermal barrier construction requirements (1) filling packing, loading, compaction, and should be uniform pressure, may not appear empty, the packing density is consistent; (2) it is strictly prohibited to all kinds of packing layer filling structure produce bridge phenomenon; (3) vibration area of thermal barrier, which pack method shall be adopted. (4) to pass the granular thermal insulation material is used for the pipeline construction in the gutter, appropriate granular insulation with asphalt or hate water immersion and drying, filling while slight fever. (5) filling method in vertical equipment construction, should be layered filling, layer should be even and symmetrical, between each layer of highly appropriate for 400 to 600 mm. (6) paste method 1. The method of paste Paste method is to use all kinds of adhesive paste insulation products directly on the surface of the equipment and pipeline, the construction method. Suitable for all kinds of light insulation products, such as plastic foam, foam glass, half hard or soft mat, plate, etc. Elected by the paste method for thermal barrier construction need to pay attention to the performance of the adhesive effect, namely the use of adhesive must conform to the adiabatic temperature medium temperature, the surface of the insulation and thermal insulation materials used no corrosion, and there are quite a strong cohesiveness. 2. Paste method construction requirements (1) the paste operation, continuous paste height, should be determined based on the adhesive curing time. Insulation products increases with the increasing visc
