Description
Technical Field
[0001] The utility model relates to the technical field of steam insulation pipes, in particular to a high-strength anti-bending steam insulation pipe. Background Art
[0002] Steam pipe is a kind of thermal pipe, which is suitable for the insulation projects of various cold and hot water high and low temperature pipes. Steam pipe has good mechanical properties and thermal insulation properties, which is suitable for the insulation projects of various cold and hot water high and low temperature pipes.
[0003] At present, when installing steam insulation pipes, since most of them are near cities, if the steam insulation pipes are erected and installed, many factors such as pedestrians and vehicles need to be considered, and the workload and maintenance are too cumbersome. When burying the steam insulation pipes underground, it is only necessary to dig trenches and bury the steam insulation pipes underground, which avoids the steam insulation pipes from being exposed to the outside world, and at the same time reduces the situation that people touch the steam insulation pipes, and avoids the steam transmitted by the steam insulation pipes from causing harm to people. Steam is transmitted underground, and the insulation materials of the composite insulation buried steam pipes are tightly combined with the pipelines without gaps, and the protective layer is also tight. In addition, the soil also plays a role of insulation, which reduces heat loss and has good energy-saving effect. For this reason, most of them are steam insulation pipes. It is installed and buried underground. When the laid pipeline is too long, it will be spliced and combined through multiple sections of steam insulation pipes. At the connection between the two sections of steam insulation pipes, most of them are made by welding to seal the connection between the two steam insulation pipes to prevent steam leakage during transportation. However, since the connection between the two steam insulation pipes is filled with welding, the steel pipes at the connection of the two steam insulation pipes are damaged under the action of high temperature of welding, making the connection between the two steam insulation pipes more prone to deformation than other steam insulation pipes, which will cause the transported steam to leak to the outside from the deformed and cracked places of the steel pipes. For this reason, a high-strength anti-bending steam insulation pipe is proposed to solve the above problems. Utility Model Content
