PVC-U材料轻便：PVC -U材料的比重只有铸铁的 1/10，运输、安装简易，降低成本。 抗化学性优越：PVC-U具有优良的抗酸碱性能，除接近饱和点强酸碱或强的 Oxidising agents atmaximun 外。 不导电：UPVC 材料不能导电，也不受电解，电流的腐蚀，应此无需二次加工。 不能燃烧，也不助燃，没有消防顾虑，价格低，使用PVC -U胶水连接实践证明可靠、安全，操作简便，耐用，抗候性优良，也不能被细菌及菌类所腐化。 阻力小，流率高：内壁光滑，流体流动性损耗小，加以污垢不易附着在平滑管壁，保养较为简易，保养费用较低。
PVC-U material is portable: the proportion of PVC -U material is only 1/10 of cast iron. It is easy to transport and install, and reduces the cost. Anti chemical superiority: PVC-U has excellent acid and alkali resistance, except near saturation point strong acid base or strong Oxidising agents atmaximun. Non conductive: UPVC material can not be conductive, and is not subjected to electrolysis or corrosion of current. It should not require two processing. It can not burn or burn up, and has no fire concerns and low prices. The practice of using PVC -U glue to connect is proved to be reliable, safe, easy to operate, durable, good weather resistance, and can not be corrupted by bacteria and fungi. The resistance is small, the flow rate is high: the inner wall is smooth, the flow loss of the fluid is small, and dirt is not easy to adhere to the smooth pipe wall, so the maintenance is relatively simple and the maintenance cost is low.
