Abstract

The invention provides a pipeline structure capable of preventing scouring and flow accelerated corrosion and changing the flow direction of fluid. The pipeline structure comprises a first straight pipe section and a second straight pipe section, wherein the first straight pipe section and the second straight pipe section are connected through a connecting component used for buffering the flow speed of the fluid. The novel structure for changing the flow direction of the fluid provided by the invention has great significance in prolonging the service life of a pipeline system, reducing the maintenance difficulty of the pipeline system and improving the safety and the reliability of pipeline operation, and also has very wide application prospects.

Description

technical field [0001] The invention belongs to the field of pipeline structure design, and in particular relates to a pipeline structure for changing fluid flow direction and preventing erosion and flow accelerated corrosion. Background technique [0002] Steam and water pipelines for thermal power, nuclear power, heating, etc., during maintenance, it was found that the metal surface in some areas was rough, bright, and orange-peel-like, showing the characteristics of wear and corrosion. When flow-accelerated corrosion occurs in equipment, when considering the factors of water vapor flow rate, the actual situation of equipment and pipeline design and layout should also be considered. For example, when water vapor enters the thick pipe from the thin pipe, flows through the shrinkage cavity, enters the elbow or enters the branch pipe of the header, even if the flow rate is not high, it will generate strong turbulent flow, which will also cause flow-accelerated corrosion. In ...
