Sichuan PPH storage tank manufacturing
Pph storage tank is a kind of plastic container made by rotational molding process. it has become the equipment needed for chemical industry, smelting, mining and new materials. Do you know what problems should be paid attention to during the installation and use of pph storage tank? The platform for installing pph storage tank shall be able to bear the weight of storage tank and solution. The platform shall be flat and smooth to prevent some sharp objects from damaging the storage tank. If heavy additional equipment is installed on the tank, or if a person needs to work on the top of the tank but the tank cannot bear the weight of a person, support or related equipment should be used to assist in the operation. When the liquid inlet is higher than the tank bottom, the liquid inlet shall bend towards the tank wall to let the incoming liquid flow along the tank wall, so as to reduce the direct impact of liquid on the tank bottom. When storing chemical liquids, first communicate with the manufacturer to determine the specifications of storage tanks, such as thickened storage tanks. In use, if pph storage tank needs to be monitored, it can be monitored by level gauge or induction device. When it has been used for a long time, please refer to the storage requirements of pph storage tank and clean the residual liquid in the tank in time. If a large amount of liquid is sucked in and discharged from the pph storage tank, special technicians need to be arranged to install the corresponding exhaust pipe.

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.

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.

The main contents of cleaning the HDPE storage tank are as follows: at the end of each manufacturing, clean the surface of the HDPE container with fingers, and continuously clean the outside of the mechanical equipment with a large amount of water. Damage to the thermal insulation layer is strictly prohibited. According to the processing technology, the solution can be cleaned after a certain period of time. For a long time, more than 72 hours, machines and equipment should be cleaned again before class. It is forbidden to enter acid liquor into the bobbin of this commodity. If the cleaning box requires acid, do not use acid with pH<2. Once the acid enters the casing of this mechanical equipment, hydrogen effect will occur, and the surface will fall like a fish scale on a large scale. The general cleaning cylinder uses 2% of sodium hypochlorite solution and uses tap water to clean the cylinder. The HDPE tank shall be cleaned according to the requirements of Chinese standards. When entering the machine and equipment for cleaning, the water bottle should be padded at the bottom of the sponge pad to prevent special tools from falling in. Wear rubber shoes to prevent damage to the laminated glass. To sort out the actual staff, the records must be sorted out immediately to determine the work experience and the inspection and signature of the project.

The thickness requirements for the bottom plate and top plate of PPH storage tank, the previous welding process is to use a portable welding gun to melt the welding rod, and then weld the tank body and bottom plate together. Since the welding rod is an external accessory, it cannot guarantee the consistency of the material with the bottom plate and tank body, which has a certain impact on the quality of equipment. Using a portable welding gun to weld, it cannot achieve the same welding strength, and the weld surface is uneven, There are many hidden dangers for equipment leakage. The bottom plate and can body are welded by mechanical welding process, which can be divided into external welding and internal welding. The external welding of PPH storage tank is a process that uses the imported automatic extrusion welding unit to realize the one-time welding molding of large welds at the stressed parts of the storage tank. 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. Internal welding is an automatic long arm extrusion welding process, which is an important step in all processes. Its principle is the same as external welding, but its equipment is different.

The performance characteristics of PPH storage tank are anti-corrosion and free of leakage. Easy to install, maintain and replace. Long service life, good sealing performance. High polymer plastic sliding roller can prevent the strip steel surface from being pulled during pickling. PPH storage tanks are commonly used for the storage and temporary storage of production materials in chemical, petroleum, medicine, food, grease, printing and dyeing, metallurgy, environmental protection, light industry and other industries. Because PPH storage tank has unique advantages over traditional anti-corrosion tank. Next, the advantages of PPH storage tank are introduced in detail. PPH storage tank has good integrity, no welding, no leakage, impact resistance, high tensile strength, good aging resistance, and meets the hygienic food standards. Due to the good performance of LLDPE and the special structure of polypropylene rolling tank, the service life of LLDPE can reach more than 15 years. Good chemical resistance. Except for some solutions that can make it expand, it can bear most of the material solutions. Polypropylene tank has the characteristics of internal and external anti-corrosion, and can be placed in a highly corrosive environment. Generally, the working conditions of storage tanks are atmospheric temperature and pressure; Under special circumstances, the working conditions of the storage tank can be lower than 70 ℃, and the hydraulic pressure can be less than 1 kg/cm2.
