Deyang polyurethane pipeline stock Deyang polyurethane pipeline I. Classification of cracks in the external insulation system of polystyrene board thin plastering external wall Cracks caused by the base structure under the insulation layer and extending to the surface layer These cracks are mainly manifested as: 45 ° oblique cracks between the frame beam column and the infill wall, window corners, and other structural cracks caused by settlement and load.Cracks caused by defects in the insulation layer, cracks in the surface layer caused by deformation and shrinkage of the plate joints, cracks at the junction of insulation and non insulation, cracks caused by inadequate bonding and anchoring of insulation boards, hollowing, etc. Cracks in the plastering mortar layer above the insulation layer, cracks caused by inadequate treatment of window sills, parapets, etcCracks caused by grid cloth lapping not in place.
The steel sheathed steel thermal insulation pipe is composed of working steel pipe for conveying medium, glass wool thermal insulation layer, aluminum foil reflective layer, stainless steel fastening belt, sliding guide support, air insulation layer, external protective steel pipe and external anti-corrosion layer, which are combined outward through the equipment in turn. The insulation structure of steel sheathed steel insulation pipe can be divided into internal sliding type and external sliding type according to different sliding modes 1. Internal sliding type: the insulation structure is composed of working steel pipe, aluminum silicate, drag reduction layer, microporous calcium silicate, thermal insulation layer, stainless steel fastening steel strip, aluminum foil reflective layer, polyurethane insulation layer, outer steel pipe, and external anti-corrosion layer (basically not used). 2. External sliding type: the thermal insulation structure is composed of working steel pipe, glass wool thermal insulation layer, aluminum foil reflective layer, stainless steel fastening belt, sliding guide bracket, air insulation layer, external protective steel pipe and external anti-corrosion layer. Advantages of steel sheathed steel insulation pipe 1. Anticorrosive coating: protect the outer steel pipe from corrosion and prolong the service life of the steel pipe. 2. External protection steel pipe: protect the insulation layer from groundwater erosion, support the working pipe and be able to bear certain external loads, and the working pipe works normally. 3. Glass wool thermal insulation layer and air thermal insulation layer: medium temperature, and the surface of external protective tube shall be kept at normal temperature. 4. Aluminum foil reflective layer: organic foam material does not enter the inorganic hard high temperature resistant layer;Reflect some heat from the high-temperature resistant layer. 5. Inorganic hard insulation layer: high temperature resistance, interface temperature between organic insulation layer and foam will not be carbonized. 6. Stainless steel fastening band and sliding guide bracket: free movement of working steel pipe due to thermal expansion and cold contraction. 7. Working steel pipe: the conveying medium flows normally.
Polyurethane insulation pipe is an important building material in real life.It has been widely used in some different shell buildings, but this kind of insulation pipe can effectively control the temperature of a place. In fact, the insulation pipe is transported and used in the process, and more and more people are recognized. What structure is its interior? In fact, the layer structure of polyurethane insulation pipe is steel pipe layer, which works. This structure is completely designed according to the actual needs of customers, and the surface of steel pipe is usually processed, and then according to different levels.To deal with or divide. The second layer is the insulation layer of polyurethane insulation pipe.This layer is usually used together with the high-pressure foaming machine to form some different foam plastics between the steel pipe and the outer layer, and then the storage solution is injected into it to make the heat preservation available. The third layer is high-density polymer.This material is usually used to protect the insulation layer of the entire polyurethane insulation pipe and avoid damaging other hard objects.Direct damage, it can effectively play the role of waterproof and radiation protection.However, there will be a leak alarm line on the outer layer of the entire polyurethane insulation layer.When the whole alarm line can not see the steel pipe insulation layer, it can basically give full alarm. Once the whole steel pipe itself has disclosed the situation, then through the conduction of the whole alarm line, more employees will usually learn the practical role of the insulation pipe.
