A device for correcting the wall of titanium pipe

Abstract

The invention discloses a device for correcting the pipe wall of a titanium pipe, which belongs to the technical field of correction devices, and comprises a casing, the inner wall of the casing is connected with a turntable in cooperation with rotation, the inner wall of the turntable is welded with protruding blocks, and the inner wall of the turntable is connected with a sliding fit There is a cross bar, the surface of the cross bar is welded with an extension block, the surface of the cross bar is slidably connected with a moving block, the inner wall of the moving block is slidably connected with a slope, the surface of the moving block is welded with a fixed block, and the fixed block There are buckles on the surface of the block with sliding connections. Through the long cross bar, the whole device can correct all the inner walls of the pipe externally, which greatly increases the efficiency of the overall use, and realizes the adjustment of pipes of different diameters through the mutual cooperation of the inclined surface and the extension block. Through the mutual cooperation of the pipe ledge and the telescopic rod, workers can easily work outside, reducing the consumption of manpower.

Description

technical field [0001] The invention relates to the technical field of correction devices, in particular to a correction device for titanium pipe walls. Background technique [0002] Titanium tubes are light in weight, high in strength and superior in mechanical properties. It is widely used in heat exchange equipment, such as shell and tube heat exchangers, coil heat exchangers, serpentine tube heat exchangers, condensers, evaporators and pipelines, etc. Many nuclear power industries use titanium tubes as standard tubes for their units. However, there are many defects in removing inner surface defects, such as inward folds. Features: On the inner surface of the titanium tube, there are straight or helical, semi-helical jagged defects, warped skin. Features: The inner surface of the titanium tube shows straight lines or intermittent nails A raised skin. It often appears at the head of the capillary, and it is easy to peel off, etc., so the inner wall needs to be polished ...

AI Technical Summary

Problems solved by technology

[0004] The deficiencies of the above-mentioned titanium pipe wall correction device: 1. When using the above-mentioned titanium pipe wall correction device, the correction of the overall inner wall of the pipeline cannot be well performed, which greatly reduces the efficiency of use; 2. When using the above-mentioned titanium pipe wall correction device, the pipe cannot be fixed well, which greatly increases the manpower required for correction and greatly increases the cost of correction
