Medium repair: eliminate running, emitting, dripping and leakage, clean or replace the liquid level gauge, repair or replace the inlet and outlet and sewage valves, dredge and clean the cooling water coil. Check and repair the safety valve to vent the flame arrester. Repair the anti-corrosion coating and thermal insulation coating. Overhaul: including medium repair items to repair the inner parts of the storage tank, and repair or replace the barrel section accordingly for the parts found to have cracks and serious corrosion. Repair can use polymer composite repair. According to the internal and external inspection requirements, and after repair or replacement of the barrel section, leak test or hydraulic test is required. Comprehensive except embroidery insulation. Internal and external inspection of storage tank

Maintenance methods and quality standards The repair of stainless steel storage tanks, such as opening holes, repair welding, replacement of tube segments, etc., shall be based on the "Capacity Regulations" and other relevant standards, specifications to develop specific construction plans and approved by the unit's technical responsibility. The materials and valves used for repair shall have quality certificates. When using old materials, valves and fasteners, they must be inspected and qualified before use. The fasteners for assembling the storage tank shall be coated with lubricating material, and the bolts shall be tightened in turn according to the opposite corners. Non-metallic gaskets are generally not allowed to be reused. When selecting gaskets, the corrosion of the medium should be considered. The anti-corrosion and heat preservation work can only be carried out after the repair has passed the inspection.
