UPVC塑料管有许多优点,但是它毕竟强度仍不及金属管材,因此在设计使用当中,不认真考虑它本身的特点,设计不合理,仍会导致系统的故障而影响UPVC塑料管系统的工作。在选用UPVC塑科管作为建筑排水之用时,首先应考虑所排的水质水温。UPVC塑料管具有良好的耐蚀性能,特别是对无机酸、碱、盐具有优良的抗蚀性能,但芳香烃类的有机化合物对它有侵蚀作用,因此用于一般工业废水 UPVC plastic pipe has many advantages, but its strength is still inferior to metal pipe, so in the design and use, do not seriously consider its own characteristics, the design is unreasonable, it will still lead to system failure and affect the work of UPVC plastic pipe system. When UPVC plastic pipe is used as a building drainage, the water quality and water temperature to be discharged should be considered first. UPVC plastic pipe has good corrosion resistance, especially has excellent corrosion resistance to inorganic acids, alkalis, and salts, but organic compounds of aromatic hydrocarbons erode it, so it is used in general industrial wastewater
