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 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.

When the storage tank made of polyethylene is produced and processed again, it does not need to use traditional welding, so its volume will be larger when it carries liquid. Because the HDPE storage tank does not need to be welded, so there is no weld. When it is used again, it does not need to worry about instability due to too much carrying liquid. Generally speaking, most storage tanks have a stability coefficient. The reason why the stability performance of storage tanks is different is that the performance of raw materials used is different. If the materials used are poor, even if the process is good, the stability performance is not guaranteed. When selecting raw materials for storage tanks, the first thing we should do is to check the quality certificate and inspection report of the raw materials. After checking, all data can be put into production only if they meet the standards. Besides, plates are used at the top and bottom of the tank, so there are requirements for plates.

In the use of PPH storage tank, the process of reaction material mainly depends on the change of storage tank temperature to realize the reaction. When designing PPH storage tank, its pressure and temperature should be standardized. The pressure here refers to the gauge pressure unless otherwise specified. Working pressure refers to the possible high pressure at the top of the container during normal operation. Design pressure: the pressure used to determine the shell thickness at the corresponding design temperature. 1.05 times the high working pressure shall be taken for the internal pressure vessel, and the static pressure of the liquid shall be included. The design pressure of external pressure vessel shall not be less than the possible large internal and external pressure difference under normal operation; Test pressure: refers to the pressure at the top of the vessel under pressure test; The vacuum vessel is designed according to the external pressure. When a safety control device (such as a vacuum relief valve) is installed, the design pressure is taken as the smaller value of 1.25 times the internal and external pressure difference or 0.1MPa, or 0.1MPa if there is no safety control device.
