Prior to flooding, carefully inspect the flooding route to ensure safety and unobstructed flow. We check for any anomalies, water leakage, and equipment failures along the route. For Quzhou's engineering polypropylene PP pipes, inspect the water quality and appearance at the flooding outlet. After flooding, attempt to close both the incoming and outgoing gates simultaneously. If not possible, initially close the outgoing gate but not fully, and wait until the incoming gate is closed before fully closing the outgoing gate. After flooding is complete, the pipeline should retain water for more than 24 hours before testing. Once flushing and disinfection are done, promptly dismantle temporary facilities. Inspect the FRPP pipe site, and restore original facilities.
It's worth noting that it maintains excellent impact strength in liquid nitrogen (-195°C), a property not found in other plastics. Additionally, engineering polypropylene PP pipes, how much are they? They exhibit higher surface hardness under repeated impacts. The self-lubricating UHMWPE has an extremely low coefficient of friction (0.05～0.11), thus offering superior self-lubricating properties. Table 1 compares the coefficient of friction of UHMWPE with other engineering plastics. From Table 1, it can be seen that the dynamic friction coefficient of UHMWPE under water-lubricated conditions is half that of PA66 and POM, and in non-lubricated conditions, it ranks second only to the self-lubricating polytetrafluoroethylene (PTFE) among plastics. When it operates in sliding or rotating forms, it has better lubricity than steel and brass lubricated with oil.
