The method of pipe rust removal for four-column hydraulic press is introduced

The pipe of the four-column hydraulic press rusted how to deal with it? Is there any way to remove rust from pipes? The following small series to introduce the four-column hydraulic press pipeline rust removal method.

First, the internal circulation pickling method is to disconnect or remove the hydraulic element in the installed liquid pipeline, and connect it with a hose, a nozzle and a washing cover plate to form a washing circuit. Use the pickling oil pump to drive the acid into the circuit for circulating pickling. This pickling method is a relatively advanced construction technology at present, with the advantages of fast pickling speed, good effect, simple process, convenient operation, etc., reducing environmental pollution, reducing labor intensity, shortening the pipeline installation period, solving the problem of difficult pickling of long pipelines and complex pipelines, and thoroughly solving the secondary pollution problem that the tank pickling method is prone to occur during assembly. Therefore, it is widely used in pickling of four-column hydraulic system pipelines.

Second, the trough pickling method is to remove the installed pipe, decompose it and soak it in the pickling tank, and carry out secondary installation after qualified treatment. This method is more suitable for short pipe with large diameter, straight pipe, easy disassembly, small pipeline construction, such as hydraulic pump station, valve station and other hydraulic devices in the pipe distribution and small field distribution of four-column hydraulic press system, can be used trough pickling method. A key (explanation: an important part of things) link to ensure the reliability of the hydraulic press system when pickling the pipeline must be paid attention to.
