Technical Field

The application relates to a corrugated pipe, in particular to a super-strong corrosion-resistant corrugated pipe.

Background

Corrugated pipes are often used for ship expansion joints, and after the corrugated pipes are used for a long time on the sea, the corrugated pipes are often corroded and rusted even if stainless steel materials are adopted due to seawater corrosion.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a superstrong corrosion-resistant bellows.

In order to achieve the above object, the present invention provides the following technical solutions.

The embodiment of the application discloses superstrong corrosion resistant bellows, including the bellows body, bellows body overcoat is equipped with the aluminum pipe, aluminum pipe internal surface laminate in bellows body surface, aluminum pipe surface mounting has a box body, demountable installation has the magnesium anode stick in the box body, the aluminum pipe with be connected with the wire between the magnesium anode stick, the bellows body including laminate in the stainless steel of aluminum pipe internal surface is outer, the outer inboard of stainless steel is formed with the metal inlayer, the stainless steel outer with the centre gripping has non-metallic film between the metal inlayer, the coating of metal inlayer internal surface has anticorrosive coating.

Preferably, in the above ultra-strong corrosion-resistant corrugated pipe, the non-metal film is a polytetrafluoroethylene film layer.

Preferably, in the super corrosion resistant corrugated pipe, the metal inner layer is made of ordinary low carbon steel.

Preferably, in the above ultra-strong corrosion-resistant corrugated pipe, the wire is a copper wire.

Compared with the prior art, the utility model has the advantages of: the aluminum pipe is sleeved outside the stainless steel and connected with the magnesium anode rod through a lead, so that the stainless steel outer layer forms a cathode, corrosion is transferred to the magnesium anode rod, the magnesium anode rod plays a good protection role, the corrugated pipe is prevented from being corroded through the double-layer effect of the stainless steel and the magnesium anode rod, and only the magnesium anode rod needs to be replaced regularly; the corrugated pipe body reduces the overall stress level of the corrugated pipe through the stainless steel outer layer, the metal inner layer and the non-metal film between the stainless steel outer layer and the metal inner layer, effectively prevents corrosion cracking and prolongs the service life; the inner layer anticorrosive coating further enhances the anticorrosive performance.
