Zhuhai PPH storage tank installation
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 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.

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.

What are the anti-corrosion treatment of PPH storage tank? For PPH storage tanks storing oil and product oil, since the performance required by the anti-corrosion materials in PPH storage tanks is electrostatic conduction, all PPH storage tanks shall be subject to anti-corrosion treatment with electrostatic conduction coating. The treatment of the external anti-corrosion coating of the tank is a comprehensive treatment that takes into account the anti-corrosion performance, weather resistance and aesthetic performance of the tank. In the design of anti-corrosion coating for PPH storage tank, it is necessary to consider that each anti-corrosion coating has temperature resistance and compatibility. If the alkyd anti-corrosion coating is used, it is necessary to avoid direct matching, because it will react with zinc powder. The cathodic corrosion protection of the tank is divided into impressed current cathodic protection on the outside of the bottom plate of the tank, and protective treatment on the anode of the ponding layer in the tank.
