MTSH-18型金属波纹管弯曲后抗渗漏试验装置试件长度取1500mm，将试件弯成圆弧形，圆管的曲率半径R应为圆管公称内径的30倍，扁管短轴方向的曲率半径R应为4000mm。
MTSH-18 type metal bellows after bending anti-leakage test device test production:
The length of specimen of MSH-18 type metal bellows after bending anti-leakage test device is 1500mm, ａnd the specimen is bent into a circular arc. The radius of curvature of the round tube R should be 30 times of the nominal inner diameter of the round tube, ａnd the radius of curvature of the short axis of the flat tube R should be 4000mm.
MTSH-18型金属波纹管弯曲后抗渗漏试验装置试件竖向放置，下端封严，用水灰比为0.50的普通硅酸盐水泥浆灌满试件，观察表面渗漏情况30min，也可用清水灌满试件，如果试件不渗水，可不再用水泥浆试验。
MSH-18 type metal bellows after bending anti-leakage test device test method:
MSH-18 type metal bellows bending anti-leakage test device specimens placed vertically, the lower end of the seal, water cement ratio of 0.50 ordinary silicate cement slurry filled with specimens, observe the surface leakage for 30min, can also be filled with water, if the specimens do not seepage, can no longer cement slurry test.
三、MTSH-18型金属波纹管弯曲后抗渗漏试验装置实验结束清理试验装置表面，以备下次使用。
