What are the differences between PP wound storage tanks?

Compared with traditional stainless steel tanks, the mechanical strength of stainless steel tanks is higher than that of PP wound tanks, but dangerous chemical tanks are generally placed statically, so the mechanical strength of tanks is not high. In terms of maintenance, PP winding storage tank is simple in maintenance and tools, which can be handled by the manufacturer. In addition, in the storage of hazardous chemicals, the service temperature of PP winding storage tank can reach 100 ℃, and its ex factory service time is usually 8-10 years, with a long service life. PPH storage tank

The main difference of polypropylene PP tanks with the same material is that the proportion of each component is different, and the different proportion of each component leads to the difference in physical and chemical properties. In addition, they also differ in processing technology. PP tank body manufacturers adopt the traditional plate splicing process, manual blow welding, and some more advanced semi-automatic processing, such as welding machine cylinder processing, automatic welding gun drag welding, etc. The defect of the original processing method is that the influence of human factors is too great. In addition, the process itself also has defects. The welding of the cylinder will directly lead to the reduction of its strength.

PP winding storage tank adopts new spiral winding superposition technology and molding process. This technology removes the welds on the cylinder, and the thickness of the equipment is not limited by the plate, so the thickness of the lower half to the upper half of the cylinder can be reduced without affecting the integrity of the equipment. At the same time, the top cover and bottom plate are also welded by automatic spiral extrusion welding machine, which improves the safety factor and strength. These technologies not only ensure the safety of the storage tank, but also greatly save the cost and have advantages in price.

In conclusion, PP wound storage tanks are more advanced than other tanks in terms of materials, price and processing technology.
