IIIInstructions for Use:

1. Take a long one1100mmThe sample is vertically fixed on the testing platform, and a suitable bending support plate is selected with an inner diameter of ≤90The selected curvature radius is1500mmThe support plate has an inner diameter greater than90The selected curvature radius is1800mmThe support plate.

2. On the upper part of the sample900mmSlowly bend the sample to the curved template position on both sides by hand within the specified range. Bend back and forth five times.

3. When the sample is bent to the final beam position, maintain the bent state2After minutes, select a bellows flexible plug gauge that is suitable for the diameter of the pipe, place it in the bellows, and observe whether the plug gauge can pass smoothly. If the plug gauge can pass smoothly, the flexibility of the plastic corrugated pipe is qualified. On the contrary, it is not a qualified product.
