Abstract

The invention discloses a double-metal composite tube with a rubber interface structure. The double-metal composite tube comprises a base tube, a rubber layer and an inner liner tube which are tightlycombined from outside to inside in sequence. The invention further discloses a manufacturing method of the double-metal composite tube with the rubber interface structure. According to the double-metal composite tube, the problem that the bonding strength of a base tube and a lining tube is low in the prior art is solved.

Description

technical field [0001] The invention belongs to the technical field of composite pipes, relates to a bimetallic composite pipe with a rubber interface structure, and also relates to a method for manufacturing the bimetallic composite pipe with a rubber interface structure. Background technique [0002] Bimetallic composite pipe is mainly used in subsea oil and gas transportation, and its structure is mainly composed of base pipe and liner pipe. Among them, the base pipe is mainly composed of carbon steel pipe or low alloy steel pipe, such as image 3 and Figure 4 As shown, the main function is to resist pressure and support the lining pipe; the lining pipe is mainly composed of corrosion-resistant materials such as stainless steel and iron-nickel alloy, and its main function is to resist the corrosion of the oil and gas medium on the pipeline and improve the service life of the pipeline . [0003] Due to the low bonding strength (axial shear separation strength) of the bim...
