Abstract

The utility model discloses a multichannel metal corrugated pipe, which comprises a pipe body, wherein one end of the pipe body is connected with a connecting piece in a threaded manner, the inner wall of the connecting piece is clamped with a plugging net, a plugging block is clamped at the interval of the plugging net, corrugated plate intervals are arranged in the pipe body, an electroplated layer is electroplated on the surface of the pipe body, and an anti-oxidation layer is coated on the surface of the electroplated layer. This multichannel metal bellows sets up the buckled plate and makes the body form multichannel bellows, and buckled plate and body integrated into one piece, makes middle passageway form the multilayer pipe wall, and middle buckled plate reduces with air contact, has slowed down the oxidation of buckled plate, can be when the body outer wall is damaged through shutoff protection network and shutoff stopper simultaneously the corresponding passageway of shutoff, does not influence the use of body to the life of extension metal bellows.

Description

Multichannel metal bellows

Technical Field

The utility model relates to the technical field of corrugated pipes, in particular to a multichannel metal corrugated pipe.

Background

The metal bellows is a tube with a regular wave-like shape, and the common metal bellows is made of carbon steel, stainless steel, plastic-lined steel, aluminum and the like. The device is mainly used for non-concentric axial transmission with small bending radius, irregular turning and expansion, absorption of thermal deformation of the pipeline and the like, or connection of the pipeline and the pipeline in the occasion of inconvenient installation by using a fixed elbow, or connection of the pipeline and equipment. The metal corrugated pipe is widely applied to the fields of automatic control and measuring instruments, vacuum technology, mechanical industry, electric power industry, transportation and atomic energy industry and the like, and the outer wall of the metal corrugated pipe is corroded by humid air for a long time under the external environment, so that the outer wall of the metal corrugated pipe is more easily corroded, and the service life of the metal corrugated pipe is influenced.
