| pvc管有较好的抗拉、抗压强度，不过柔性不如其他塑料管好。PVC管材的管壁非常光滑，因此水流的阻力很小，它的输水能力比同等管径的铸铁管提高20%，输水效果非常高。而且pvc管的耐腐蚀性和耐药品性也很好，具有很好的耐酸，耐碱，耐腐蚀，不受潮液压钢坝 湿水份和土壤酸碱度的影响，使用寿命很长。 PVC pipe has better tensile and compressive strength, but its flexibility is not as good as other plastic pipes. The wall of PVC pipe is very smooth, so the resistance of water flow is very small. Its water conveyance capacity is 20% higher than that of cast iron pipe with the same diameter, and the water conveyance effect is very high. Moreover, the corrosion resistance and drug resistance of the PVC pipe are also very good. It has good acid resistance, alkali resistance and corrosion resistance. It is not affected by moisture and soil acidity and alkalinity, and has a long service life |
