PPH winding tank In the process of processing, 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, service life, mechanical strength and other properties of the tank.

PPH particles are melted on the screw extrusion and winding unit, and then the melted extrusion material is formed on the mold to form the tank body. When the temperature is reduced to a certain extent, the mold is demoulded, which can ensure the integrity of the molding. In the traditional processing form, the plate is butt welded to form the tank body. Since the plate width is 2000mm and the tank body height is generally greater than 2000mm, the tank body is formed by manual welding in actual processing. Add reinforcing rings at the body splice. PPH winding tank is directly processed and formed by PPH particles, while the traditional method is to process the particles into sheets, and then process the sheets into tank bodies; In addition, the PPH wound tank has no problems of joints and welds. Moreover, since no chamfer welding is required, the overall mechanical strength is greater than that of the tank processed by traditional processes.

In all polypropylene pipes, experiments show that PPH has strong chemical resistance. Especially after the extrusion winding process is adopted, compared with the original sheet metal processing process, there is no weld and weld problem, and the mechanical strength and safety reliability performance are improved. These characteristics are suitable for the technical requirements of the new energy field. PPH mixing tank The welding between the bottom and the tank bottom is the part bearing great stress. Mechanical cantilever welding is adopted in the tank and at the tank bottom, which can realize one-time large welding without repeated welding and can withstand various corrosive liquid operations.
