DN150 metal bellows compensator application tips
For DN150 metal bellows compensator of different materials and wall thickness, different forming processes are usually used. For installation, the DN150 metal bellows compensator can be installed directly on the pipeline according to the connection and according to the use position. Generally speaking, can be installed in any position of the pipeline, but need to be sealed to prevent the spread of leakage phenomenon, affecting the normal work of the pipeline. DN150 metal bellows compensator when the material is pulled on the outside, the inner side of the neutral axis of the location and DN150 metal bellows compensator method is different. In the top bend (compression bend) work, the neutral axis is about 1/3 from the outer wall, in the metal bellows compensator work, the neutral axis is about 2/3 from the outer wall. therefore, conducive to the bending of thin-walled pipes. R is now provided for users to refer to when selecting the relationship between pipe diameter and wall thickness. Reflecting the relative bending radius and wall thickness on the quality of metal bellows compensator. According to the pipeline processing acceptance specification, the metal bellows compensator is 4D, and the medium and low pressure is 5D.
Metal bellows compensator stored for a long time, should be inspected on time, the exposed processing surface often to keep clean, remove dirt, stored in a dry indoor ventilation, prohibit stacking or open storage. Metal bellows compensator often keep dry and breathable, keep the vessel clean and tidy, stored in the correct way.
The bending performance and surface corrosion of the pipe itself may also affect the quality of the metal bellows compensator. When the site construction, the operator also needs to understand the material, processing performance and surface corrosion of the pipeline being processed. When pure bending, the pipe is under the action of external force distance M. The outer arm wall of the neutral layer is thinned by the tensile stress &1 and the inner side is under compressive stress.
