FRP Septic Tank Hand Lay-up vs Mechanical Winding


FRP septic tank is special equipment for the treatment of domestic sewage. There are two production processes, one is the hand-made process (referred to as the hand lay-up process), and the other is the mechanical winding process. Let’s take a closer look at these two production technologies.

From the product’s appearance, the handmade products are bright and bright; the mechanized products have good toughness and texture, and the two are not inferior.

From the production process point of view, it is evident that the mechanized production process is advanced, especially the large-scale septic tanks. The diameter of the tank is large, the pressure resistance requirements are high, and the mechanical winding process is denser, because the overall winding is controlled by computer automation, and the quality is relatively high. However, the manual method is more stable due to uncontrollable factors of employees and many product interfaces, resulting in poor product stability. The manual process is more suitable for septic tank products with low-stress requirements and no load under 2 meters in diameter.

The FRP septic tank needs to be paid attention to during transportation and storage: it should be stable during loading, unloading, and transportation, and soft pads should be placed in the conflict to avoid collision with the carriage. A red mark should be added for superelevation; when the septic tank is being transported or installed, the wire rope should not be in direct contact with the septic tank, and should not be tied and lifted by accessories such as cleaning holes and inlet and outlet pipes, and should not be loaded and hoisted; When the tanks are shipped together, they should be separated by cushions, and should not be directly touched and bumped. Attention should also be paid to fire prevention when storing septic tanks, and direct ultraviolet rays should be avoided when storing in the open air.
