whole PPH storage tank The barrel is wound to form, the line of the equipment barrel is consistent, and the appearance is more uniform. The base adopts mechanical welding to beautify the overall weld seam, and special overall flange is used to strengthen the integrity of equipment and improve the integrity of equipment. The welding position of the nozzle adopts the pressure welding process to make the weld of the nozzle more sealed and beautiful. At the same time, we will also burr the equipment to meet the customer's experience as far as possible.
What are the acceptance points of PPH storage tank?
1. When adding water, the tightness of the tank bottom must meet the requirement of no leakage at the tank bottom;
2. The strength and sealing of the pipe wall shall meet the requirements of no leakage and abnormal deformation after the tank wall is filled with water to the design high liquid level and maintained for 48 hours;
3. The strength and compactness test of fixed roof shall be qualified if the roof has no abnormal deformation and the weld has no leakage; If the expected effect cannot be achieved after the roof is filled, it is unacceptable. Note: This test method is not applicable to the performance test of other container types; If necessary, it can also be verified by measuring the air pressure.
4. The stability test of the fixed roof shall be based on the fact that there is no abnormal deformation on the tank top. If there is looseness or falling off during installation, it shall be replaced in time. When the pressure swing exceeds the specified value after the valve is opened, necessary measures shall be taken to eliminate the influencing factors to ensure PPH winding tank Normal operation.
5. The floating roof and inner floating roof shall be lifted steadily by adding water to the floating roof and inner floating roof, and the guiding mechanism, sealing device, automatic ventilation valve column and flexible rotary escalator shall not be blocked. There is no interference between the floating roof and its accessories and other accessories on the tank body, and there is no leakage between the floating roof and its accessories and the liquid level contact part.
