The total flatness tolerance of the tube heat exchanger

Be careful when doing this work.The processing and assembly precision of the threaded locking ring of the heat exchanger is very high, and it is easy to be unable to screw out or jam in the middle. In particular, it gets stuck in the middle, which will bring great difficulties to the overhaul of the heat exchanger..

The main Heat Exchangers FHC052 Exporters reasons for the above failures are: the outer ring of the heat exchanger can not be disassembled, resulting in the thread locking ring can not be unscrewed freely; the thread locking ring thread is longer, if there is debris or deformation on a certain part , It may jam; the heat exchanger thread locking ring is too heavy, the special disassembly tool is difficult to operate on site, and the adjustment error is considered to be unable to maintain the concentricity or verticality of the disassembly process, which may cause jam

The total flatness tolerance of the tube heat exchanger tube should not be greater than 10mm. 4. When assembling high-pressure straight pipes, elbows, connecting pipes and threaded flanges of the casing heat exchanger, ensure that the flange plane and the pipe centerline are perpendicular to each other, and the perpendicularity tolerance should not exceed 1% of the outer diameter of the pipe. 8.

Disassemble the heat exchanger to clean the interior; disassemble the interface to clean the outlet and rearrange the plates; re-select or adjust the working conditions; remove non-condensed gas; disassemble the heat exchanger and clean the plates Change the plate arrangement; change the flow rate or requirements; remove the gas and replace the condensate discharge valve or the air pump to replace the steam control valve; modify the system.
