Reaction Vessel: Maintenance of Electrically Heated Reaction Vessels and Criteria for Repairing Reaction Vessels

Electric heating Reaction vessel maintenance of

1. Electrically heated stainless steel Reaction vessel Operate and use the product strictly according to the working pressure and working temperature indicated on its nameplate to avoid potential hazards.

2. Electric heating Reaction vessel Strictly follow the cooling and lubrication instructions in the product manual, and ensure proper maintenance of the equipment.

3. Regularly adjust the oil level of the heat transfer oil to prevent the heating area from shrinking or the heating tubes from overheating and drying out, which could damage the heating elements.

4. Inspect the heat transfer oil every other year to check its degree of carbonization. If necessary, filter and reuse the heat transfer oil to remove carbonized oil deposits from the bottom of the electric heating reactor. Consider replacing the heat transfer oil under severe conditions based on the degree of carbonization. Electric heating reactor

5. Electric heating Reaction vessel The electronically controlled instruments shall be operated by designated personnel and shall be equipped with overload protection devices as required.

6. If you notice that the heating speed has slowed down compared to before, we recommend checking whether the electric heating element is short-circuited. To check, disconnect all wires connected to the electric heating element and use a multimeter to measure its resistance. If the resistance reads zero, remove and replace the heating element, then reconnect the wires.

7. Regularly inspect the connection wires and electrical components in the control box for signs of aging to prevent short circuits and accidents.

1. The weld seam and the base metal should transition smoothly.

2. The depth of partial undercutting in the weld shall not exceed 0.5 mm, and the length of the undercut connection shall not exceed 100 mm.

3. The weld shall be free of defects such as cracks, fissures, insufficient penetration, inadequate fusion, slag inclusions, and porosity.

4. The slag and spatter on both sides of the weld shall be removed.

5. After repair, no intersecting weld seams shall be present. The longitudinal joints between two adjacent cylinders, as well as the longitudinal joints between the head and the adjacent cylindrical section, shall be arranged in an alternating pattern, with a spacing greater than three times the thickness of the simplified version and not less than 100 mm.

6. Weld repairs should not exceed two times.

7. The material of the welding electrode must be correct, and the appropriate electrode should be selected. The flux must be dry and used as needed.

8. The pot body after welding must undergo a hydrostatic strength test.
