Abstract

The invention relates to a corrugated pipe and in particular relates to an inner fin and outer rib reinforced corrugated pipe that breaks through the thinking pattern limitations in the industry and is effectively improved in pressure resistance and deformation resistance thereof. The inner fin and outer rib reinforced corrugated pipe comprises a cylindrical-surface pipe body 1 and helical surrounds 2 that helically surround the pipe body; a reinforcing inner fin 3 perpendicular to a pipe wall is contained in the helical surrounds 2 and divides the helical surrounds 2 into two parallel hollow cavities 4; a transverse reinforcing rib 5 is further arranged between every two adjacent helical surrounds 2; each transverse reinforcing rib 5 is mounted on the cylindrical-surface pipe body 1 and provided with threads on a surface thereof; due to such a structure that the transverse reinforcing rib is further arranged between every two adjacent helical surrounds and each transverse reinforcing rib is mounted on the cylindrical-surface pipe body and provided with threads on the surface thereof, the whole cylindrical-surface pipe body is covered with the helical surrounds and the transverse reinforcing ribs, such that the whole inner fin and outer rib reinforced corrugated pipe is still capable of keeping good ring stiffness under pressures or vibrations, and meanwhile, is better in anti-deformation capability.

Description

technical field [0001] The invention relates to a corrugated pipe, in particular to a corrugated pipe reinforced with internal ribs and external ribs. Background technique [0002] Bellows, a cylindrical thin-walled corrugated shell with multiple transverse corrugations. Bellows are generally made of PP, PA or PE materials, which are elastic and can be displaced or bent under the action of pressure, axial force, lateral force or bending moment. During the bending process, since the bellows is a cylindrical thin-wall corrugated shell with multiple transverse corrugations, it can be bent in any direction. Due to the non-directional bending characteristics of bellows, it is widely used in the connection of building materials and mechanical equipment. In addition, corrugated pipes are also used as hollow reinforcing ribs in the production of outer corrugated plastic winding structural wall pipes with hollow reinforcing ribs. The main reason is to use the characteristics of cor...
