3, tensile test: the axial tension of 5KN tube wall no damage.

4, pull out test: buried in concrete pull out force for anchor bolt design pull out force for anchor bolt design pull out force 2.3 times more.

5, bending test: bending radius of curvature for 30d, no water leakage, slurry leakage.

Specifications

the material of the steel belt is 0.25mm~0.3mm thick steel belt. the thickness of the corrugated pipe (detection pipe) formed needs 0.35mm. most of the corrugated pipe used in the construction site is about 0.3mm, less than 0.03mm. the specifications of bellows can be calculated in accordance with the inner diameter, also can be calculated in accordance with the outer diameter, most of the industry according to the inner diameter, the specifications of the inner diameter have 50mm-100mm,(the coefficient of the whole ten), of course, there are 55mm bellows, as for more than 100, a lot of places are not provided.
