Abstract
The invention discloses a joint corrugated pipe. The joint corrugated pipe comprises a corrugated pipe body. A first positioning nut is arranged at one end of the corrugated pipe body. A second positioning nut is arranged at the other end, opposite to the first positioning nut, of the corrugated pipe body. The segment, located between the first positioning nut and the second positioning nut, of the corrugated pipe body is sleeved with a plurality of cylindrical sleeves and a plurality of hollow balls. Each hollow ball is arranged between every two adjacent cylindrical sleeves. First warm-keeping layers are fixedly arranged on the outer surfaces of the cylindrical sleeves and the outer surfaces of the hollow balls. First corrosion-resisting layers are fixedly arranged on the outer surfaces of the first warm-keeping layers. Sun-screening layers are fixedly arranged on the outer surfaces of the first abrasion-resisting layers. By means of the technical scheme, the joint corrugated pipe is reasonable in structural design, simple in structure, good in pressure resistance and abrasion resistance, long in service life and not prone to deformation or corrosion.
