When PPH storage tank is used, the filling rate shall not be greater than 95%, and excessive filling is strictly prohibited. Made of polypropylene, it can contain inorganic acid, malic acid, salt, ammonium, alkali, oil and most gaseous compounds under normal temperature and pressure; The lower cracking temperature and dissolution temperature of PPH storage tank are - 70 ℃ to 108 ℃, and the temperature of the liquid contained is usually between - 40 ℃ and 60 ℃; The filling rate of PPH storage tank shall not be greater than 95% when it is used, and excessive filling is strictly prohibited; When the valves, instruments, pipes, etc. on the equipment are frozen, nitrogen, air or hot water at 70~80 ℃ shall be used for thawing, and open fire heating is strictly prohibited; The PPH storage tank shall be equipped with acid and alkali resistant gaskets when containing acid and alkali liquids, and insoluble rubber gaskets when containing organic solvents; If you are not sure whether you can contain the required substances, you can consult our technical personnel, and if necessary, you can carry out the tank material sample soaking test.

Physical anti-corrosion of PPH winding tank: during processing, appropriate oily film-forming agent is used in the mesh, so that the anti-corrosion effect of the produced equipment will be much better when it is used. For example, the use of some lead containing pigments and oil together can make the anti-corrosion coating more compact, which will also reduce the penetration of substances to the equipment. Phosphate pigments are basic acid salts that are difficult to dissolve after hydrolysis, which can effectively block the pinholes in the coating. The oxide produced by iron or the flake mica powder and other pigments can reduce the permeability of the anti-corrosion coating when filling, so the PPH winding tank can play a good role in anti-corrosion physically.

PPH storage tank is a new product of polypropylene storage tank. With the rapid development of economy, the development of PPH storage tank is particularly rapid, from the previous single series to the current various types. The manufacturer of PPH storage tank is generally only responsible for the design, production, loading and transportation of the storage tank within the scope of the project. The subsequent unloading and installation are the responsibility of the customer. The manufacturer arranges one more project manager to direct the unloading and installation on site, but generally the manufacturer does not have so many project managers to assign, Therefore, it is particularly important for customers to know how to unload and install PPH storage tanks. In terms of unloading, before the storage tank is transported to the installation site for unloading, it is recommended that the customer representative inspect the storage tank to confirm that the storage tank is not damaged during transportation.

The forming process of PPH storage tank adopts spiral extrusion winding technology with reliable quality. The main processes include tank extrusion winding, external welding, internal seam welding, pipe orifice installation, etc. Can body extrusion winding is the process of using PPH spiral extrusion winding unit to process PPH granules into can body molding. The system adopts the process of hot melting PPH particles, extruding them, and then winding them onto steel dies to form cans. The production efficiency of this process is about 5-8 times higher than that of manual process, and the product is flat and beautiful, with good integrity, no joints, good corrosion resistance and leakage resistance. The tank body is thin at the top and thick at the bottom, and the size and shape of the product are not limited. External welding is the process of using the imported automatic extrusion welding unit to make the large weld of the tank with large stress be welded in one time. The new PPH granular material with the same property as the tank body is hot melted at the large weld seam, and is integrated with the tank bottom and tank body. The process features high mechanization and automation, and stable product quality. The weld specifications can be designed according to the stress characteristics of the product to give full play to the integrity of the weld, reduce flash, and make the joint smooth and beautiful. In addition, the ultraviolet absorber is added to PPH granular material to resist aging and extend the service life.
