When filling cold insulation materials in air separation equipment, the following issues should be noted:
1) Before filling, the moisture on the foundation of the cold insulation box should be dried;
2) When filling, all equipment and pipelines inside the air separation equipment should be inflated with an inflation pressure of 0.045 0.05MPa, and the valves of each gauge pipe should be slightly opened for ventilation. Simultaneously energize each platinum resistor and monitor whether the meter tube and cable are malfunctioning at any time;
3) Be careful not to mix combustible materials or get damp inside the cold insulation materials;
4) Not suitable for filling in rainy or snowy days;
5) The filling should be dense and there should be no empty space. When filling slag cotton, it should be compacted layer by layer with a wooden hammer or round headed wooden stick, and its density should be checked by sampling in the manhole;
6) Construction personnel who load cold insulation materials should take labor protection measures and pay attention to personal safety, and add iron bars at the filling port; 7) When the cold insulation material sinks after driving, attention should be paid to supplementing it.
