| 耐磨抽沙管道两大关键指标：拉伸强度和抗冲击强度。拉伸强度的高低是管材材料压力等级的表现，它直接表现为管材长期在承压条件下使用和瞬间抗水垂冲击（压力突变）而不破坏的能力。 Tensile strength and impact strength are two key indexes of wear-resistant sand pumping pipeline. Tensile strength is the manifestation of the pressure grade of pipe material, which is directly manifested by the ability of pipe material to be used under pressure for a long time and to resist water drop impact (sudden change of pressure) instantaneously without damage. 目前市面上的普通聚乙烯矿用管的拉伸强度一般在15Mpa以下，这么低的拉伸强度对于长期使用的压力管道而言，其使用安全性是可想而知的 At present, the tensile strength of ordinary polyethylene mining pipes on the market is generally below 15 Mpa, so low tensile strength for long-term use of pressure pipes, its use safety is conceivable. |
