What are the differences between plastic corrugated pipe mold and metal corrugated pipe?
With the development of society, more and more plastic bellows molds are used by more people, but do you know the difference between metal bellows and plastic bellows? Next, let's follow the plastic bellows mold manufacturer to find out.Compared with the traditional metal corrugated pipe, the corrugated pipe mould should be equipped with a special type of joint, which can be used to connect with the anchor pad of the clamp group. The connection between the corrugated pipe and the drain pipe and the corrugated pipe can discharge the pressed into the corrugated pipe Grout.
It can be seen from the calculation method and evaluation standard of the plane stability and circumferential stability of the plastic bellows that both reflect the strength problem. When the design allowable life is low, not only the meridian comprehensive stress is higher, but the hoop stress is also higher, and the local sound research will quickly enter plastic deformation, resulting in instability. The formation of plastic hinges at the peaks and troughs of the waves, coupled with pressure stress, can easily lead to instability of the plane. Therefore, the low fatigue life in the displacement state, the plane instability pressure is much lower than the high fatigue life.

In the longitudinal section, the prestressed plastic corrugated pipe is equivalent to a compressed arch beam, and the plastic corrugated pipe is in a stretched state during operation, which is equivalent to that the arch beam reduces the arch height, and its anti-instability ability is naturally reduced. When the single-wave displacement is too large, the size of the straight part of the corrugation tends to be larger, and the diameter of the wave crest net ring is fixed. In order to coordinate the deformation, the crest collapses and the circumferential instability will occur. The domestic and foreign standards for the stability of displacement and external pressure all involve the influence of the stability of external pressure, which needs to be discussed in depth.
