Description :

　　The structure of steel insulated elbows with steel sleeves can be divided into internal sliding type and external sliding type according to different sliding modes. 1. Internal sliding type: The insulation structure consists of a working steel pipe, aluminum silicate, drag reduction layer, microporous calcium silicate, insulation layer, stainless steel fastening steel strip, aluminum foil reflective layer, polyurethane insulation layer, outer steel pipe, and external anti-corrosion layer. 2. External sliding type: The insulation structure consists of a working steel pipe, a glass wool insulation layer, an aluminum foil reflective layer, a stainless steel fastening strap, a sliding guide bracket, an air insulation layer, an external protective steel pipe, and an external anti-corrosion layer. The bending radius of the steel sleeve steel buried insulation elbow design is generally not less than 3 times the nominal diameter of the working elbow, or it can be designed according to the outer sleeve elbow. The steel sleeve steel insulated elbow adopts welding connection due to its high strength, and its waterproof sealing performance is highly reliable. In addition, its high temperature resistance is unmatched by other external protective pipes. In areas with high groundwater levels, to ensure that groundwater does not affect the normal operation of steam buried pipelines, a sturdy and sealed steel pipe shell is used as the outer protective layer. The structure of steel insulated elbows with steel sleeves can be divided into internal sliding type and external sliding type according to different sliding modes. 1. Internal sliding type: The insulation structure consists of a working steel pipe, aluminum silicate, drag reduction layer, microporous calcium silicate, insulation layer, stainless steel fastening steel strip, aluminum foil reflective layer, polyurethane insulation layer, outer steel pipe, and external anti-corrosion layer. The price of steel insulated elbows with good service in Beijing includes low standard asphalt, heavy oil, etc. It melts when heated, and the pipeline can expand and contract within the insulation layer, while the insulation layer and backfilled sand remain in a static state. This detachable type is mainly used for high-temperature composite insulation pipes, such as steam pipelines. (2) Integral insulation pipe: The steel pipe, insulation material, and protective shell are firmly bonded together to form a cohesive structure. When the temperature of the steel pipe increases due to the transport medium and undergoes thermal expansion, the insulation layer expands together. Integral insulation pipes are mainly used in situations where the temperature of the heat medium is below 150 ℃. Structural performance characteristics of prefabricated thermal insulation elbow with steel sleeve: polyurethane foam layer: ensure medium temperature. The stacking height should be less than 1.5 meters. 3. Pipe lifting should be carried out with light loading and unloading, and collisions and throwing are prohibited. It is also forbidden to use steel wire ropes to directly lift the pipe body. 4. The insulation layer and anti-corrosion layer should avoid direct contact with flames. On site installation should follow the following procedures: trench excavation - foundation treatment (drainage, sand filling) - pipe laying - steel pipe welding - inspection (water pressure) - installation (pressure testing) - foaming - sealing foam holes. The installation company for elbows and joints can dispatch personnel to the engineering site to carry out insulation work for joints, including the installation of joint outer sleeves, the connection and sealing of joint outer sleeves with the main pipe, and the foaming work of on-site joints, but it does not include the welding work of steel pipes in the joint part.
