Stainless SteelChemical DrumBefore use, it should be cleaned thoroughly, and the inlet and outlet sewage valves and level gauges should be replaced in a timely manner for routine maintenance, as well as clearing and cleaning the cooling water plates. For the maintenance of the anti-corrosion layer and insulation layer of the chemical drum: when cracks or severe corrosion are found in the medium-sized chemical drum component maintenance project, attention should be paid to timely repair or replacement of cracked components. Note that polymer composite materials can be used for the repair of chemical drums. After repairing or replacing the drum section, remove the embroidery and insulate it. Then, conduct leakage tests or water pressure tests according to the requirements of internal and external inspections. Additionally, please address any other issues found during the internal and external inspections of the chemical tank in a timely manner. Now, let's understand the key points of using stainless steel chemical drums!

　　For the maintenance of stainless steel chemical drums, quality standards for opening the drum, welding, and replacing drum joints need to be established. A specific construction plan should be developed according to the tolerance standards of stainless steel chemical drums and relevant regulations, and approved by the technical department. The maintenance materials for chemical stainless steel drums (base material, welding rods, welding wires, flux, etc.), including valves used for maintenance, need to have quality certification. If valves and fasteners made from old materials are used, they need to be inspected before they can be used. The fasteners of the chemical drum assembly should be coated with lubricating oil and the bolts at the corners should be tightened. Non-metallic gaskets are generally not reusable, and the selection of gaskets should consider the corrosiveness of the medium. Please remember that chemical drums need to be repaired and inspected before use.

　　Precautions for using stainless steel chemical drums:

　　1. Stainless steel chemical drums store flammable gases and liquids. Smoking, open flames, and insulation are prohibited in the surrounding area, and entry into the tank area is not allowed. Necessary fire-fighting equipment should be provided.

　　2. When storing flammable, explosive, toxic, or corrosive media in stainless steel chemical drums, relevant laws and regulations regarding hazardous materials management must be strictly followed.

　　3. The power supply to electrical equipment related to the chemical drum must be cut off, and handover procedures for the equipment must be completed before maintenance can be carried out.

　　4. After the internal medium of the stainless steel chemical drum is drained and has clear cutoff markings, the inlet and outlet valves should be closed in a timely manner or the connected pipelines and equipment should be cut off with blind plates.

　　5. If the chemical drum contains flammable, corrosive, toxic, or asphyxiating media, timely replacement, neutralization, disinfection, and cleaning must be carried out. Analysis and inspection should be conducted after processing. Test data results need to be established to meet the requirements of relevant legal norms and standards, and combustible materials cannot be used as a substitute for air.

　　Summary: When repairing stainless steel chemical drums or replacing level gauges or inlet and outlet valves, the cooling water tray should be cleaned in a timely manner, and the lightning protection device of the safety valve should be maintained. Maintenance of coatings and insulation materials: including mid-term maintenance projects for chemical tanks, and maintenance or replacement of pipeline joints. After repairing or replacing the oil cylinder joints, leakage tests or water pressure tests should be conducted according to internal and external inspection requirements.
