GB/T35451.1-2017聚丙烯双壁波纹管材环柔性试验：截取双壁波纹管300±20mm长度试样3段，两端应与轴线垂直平整，若切割位置不在波谷处，可延长至波谷。按GB/T9647-2015规定进行试验，试验力连续加载。波纹管在垂直方向外径变形量为原外径的30％时立即卸荷，观察波纹管内壁是否保持圆滑，内外壁是否破裂，两壁是否脱开。
GB/T35451.1-2017适用于长期使用温度不超过45℃的无压埋地排水排污聚丙烯双壁波纹管材。PP管材环刚度试验按GB/T9647-2015规定进行。jnshiyanji；PP管材公称直径100～1200mm，公称环刚度8kN/m2，10 kN/m2，12.5kN/m2，16kN/m2。聚丙烯双壁波纹管材原材料检验拉伸强度、弯曲弹性模量、密度、耐内压、环应力、熔体质量流动速率、热稳定性、灰分；PP蠕变比率试验按GB/T18042规定进行，计算并外推至两年的蠕变比率。埋地排水排污用聚丙烯（PP）结构壁管道系统；30kN排水排污管材环柔性试验机；20kN通讯护套管力学试验机；50kN双壁波纹管环刚度试验机；100kN玻璃夹砂管环刚度试验机；波纹管局部横向荷载试验机；塑料波纹管纵向荷载试验机；jnshiyanji；波纹管抗均布荷载性能试验机；波纹管拉伸强力试验机；管材压扁试验机；管材抗压强度试验机；管材挠曲水平试验机；2000kN无振动万能材料力学试验机；1000kN无振动管材拉伸试验机；
