PPH tank itself uses polypropylene in some new process tanks, so it has better corrosion resistance and other properties when used. In many aspects, its performance is better than that of tanks made of other materials, and its service life is longer under natural conditions. There are many advantages, so before use, please carefully check the PPH storage tank in order to better use it. PPH storage tank shall be used before appearance inspection, and its surface shall be free of crack, shrinkage cavity, slag, folding, heavy leather and other defects. The damage depth of mechanical equipment with corrosion depth and dent depth shall not exceed the allowable value of relative product execution standards. The shell test pressure of PPH storage tank valve shall not be less than 1.5 times of the nominal pressure, and the test time shall not be less than 5 minutes. The shell packaging shall be qualified without leakage. The nominal pressure test shall be conducted, and the valve sealing surface shall be qualified. If you want to soften the PPH storage tank, the temperature is about 100 ℃, so we must control the liquid temperature between minus 40 ℃ and 60 ℃ during storage.

Why can PPH storage tank replace stainless steel? The comparison of two kinds of dangerous chemical storage tanks is made from the aspects of mechanical strength, service life, corrosion parameters, maintenance, service temperature, etc. The service life of PPH storage tank is usually 8-10 years, while that of stainless steel storage tank is 10-13 years more; The mechanical strength of stainless steel storage tank is higher than that of PPH storage tank, but hazardous chemicals storage tank is generally placed statically, instead of storage tank with high mechanical strength; PPH storage tank is resistant to most acids, alkalis, organics and mixed liquids. As long as the service temperature is within the limited range, there will be no corrosion. Many media that PPH storage tank can resist will corrode stainless steel (except special stainless steel); In terms of maintenance, PPH storage tank is simple in maintenance and tools, which can be handled by the manufacturer; The service temperature of dangerous chemicals is generally normal temperature, and the high service temperature of PPH storage tank z can reach 100 ℃.

PPH mixing tank is made by seamless extrusion winding technology. Pipe orifice, inner weld and outer weld are all processed by automatic extrusion unit equipment, which is superior, stronger and lower than plastic tanks made by traditional technology. It is necessary to use electric heating to melt and extrude the particles onto the steel mold, which consumes a lot of power. The PP storage tank only has the power of the welding gun, so it consumes less power; The PPH mixing tank is welded with a large extrusion electric heating drag gun, which consumes a lot of power. The PP storage tank uses a small manual drag gun, which consumes less power. PPH reaction kettle uses PPH spiral extrusion and winding unit to process PPH granules into tank body forming process. The system adopts the process of hot melting PPH particles, extruding them, and then winding them onto steel dies to form cans. PPH reaction kettle has the characteristics of good integrity, uniform thickness, corrosion resistance, seamless, aging resistance and good leakage resistance.

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.

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.
