PPH storage tank vertical storage tank is a plastic storage tank made of PPH granular materials after processing. The barrel of PPH storage tank is made of PPH granules through extrusion and winding process, and the product is formed at one time without welding. PPH storage tank is made of polypropylene plate by welding. From the perspective of corrosion resistance, the corrosion resistance of PPH vertical storage tank is similar to that of PPH vertical storage tank. From the perspective of safety performance, the PPH tank cylinder is integrally formed without welding and leakage, while the PPH tank is welded, which is easy to cause leakage and increase unsafe factors. And there is a big gap between the other properties of the two, such as anti-aging performance. The nozzle installation is the last process, which is equivalent to the reduced version of bottom welding. That is, the imported small automatic extrusion welding unit is used to weld the connecting pipe and flange into shape, and then the hole opener is used to cut the corresponding caliber on the tank body, and then the domestic portable extrusion welding is used. PPH storage tanks are widely used in chemical, pharmaceutical, dye, chemical fiber, metallurgy, textile and other industries to store various corrosive media. The utility model has the advantages of long service life of corrosion resistance, light self weight, safe transportation, convenient maintenance, etc.

During the processing of PPH winding tank, there are three core points: tank body fabrication, internal and external weld welding, and manhole installation. These three core points will affect the integrity, aging resistance, leakage resistance, service life, mechanical strength and other properties of the tank. PPH granular material is melted on the spiral extrusion winding unit, and then the melted extrusion material forms a tank on the mold, and demoulding is carried out after the temperature is reduced to a certain degree, so as to ensure the integrity of the tank. However, the traditional processing method is plate butt welding to form a tank body. Since the z width of the plate is 2000 mm and the tank body height is generally more than 2000 mm, in actual processing, the tank body is formed by manual welding of sections of the tank body. Then, to be safe, a stiffening ring is added at the joint of the tank body. PPH winding tank is formed by direct processing of PPH particles, without secondary processing. Traditionally, particles are processed into plates, and then the plates are processed into tank bodies; In addition, the PPH winding tank has no problems of joints, welds and leakage, and the overall mechanical strength is far greater than that of tanks processed by traditional processes because of the need for chamfer welding.

The key manufacturing method used in the production of PPH storage tank is one-time forming coiling manufacturing method, so it is simple in structure. The application of PPH storage tank is relatively convenient due to its simple construction. In the actual engineering construction and application, the vertical PPH storage tank usually only considers the static load due to the low application frequency, and the safety performance is slightly increased. For the vertical PPH storage tank with large capacity, the concrete rubber support and the metal rubber support can be considered, but the metal rubber support is too tightly bound, and the plastic has some folding and swelling, It will do harm to the compressive strength of the storage tank, and the appearance is not beautiful. It is proposed to use concrete rubber bearings. Second, for those with small capacity, it is OK to immediately consider plastic rubber bearings.

PPH tank body extrusion winding production tank body butt welding is the process of using PPH spiral extrusion winding unit to process PPH particles into tank 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 is 5-8 times higher than that of manual production. The product has good integrity, no seams, good corrosion resistance, good leakage resistance, flat and beautiful product, thin tank body and thick tank body, low price, unlimited product size and shape, and the product is processed with granular materials, with good anti-aging performance. Polypropylene tank itself has the advantage of internal and external anti-corrosion, so it can be stored in some highly corrosive environments. Because linear polyethylene is used, it has good service performance, and the special structure of polypropylene rolling tank is used, so the service life can basically reach more than 15 years. In addition, it can be used under normal atmospheric temperature and pressure when it is stored.
