Embodiment

[0017] Such as figure 1 As shown, the present invention provides a kind of corrosion-resistant metal plate, and described metal plate is carbon steel plate body, corrosion-resistant alloy layer and anticorrosion coating sequentially from the inside of plate body outward, and between described carbon steel plate body and corrosion-resistant alloy layer form a confined space.

[0018] As a preference, the anti-corrosion coating is a graphene water-based coating layer.

[0019] Further, the carbon steel plate body and the corrosion-resistant alloy layer are combined through a hot rolling process.

[0020] The metal plate used in this embodiment is a mechanical composite plate, which is a new type of plate that combines two metal plates of different materials through mechanical manufacturing processes such as hydraulic expansion method, elastic body extrusion method or explosion method. It fully combines the high-strength properties of the substrate (carbon steel body) and the e...

Abstract

The invention provides a corrosion-resistant metal plate which comprises a carbon steel plate body, a corrosion-resistant ally layer and a corrosion-resistant coating in sequence from inside to inside, wherein a sealed space is formed between the carbon steel plate body and the corrosion-resistant ally layer. The metal plate is applicable to pavement of oil-gas pipelines and is good in corrosion resistance, excellent in mechanical property and simple in preparation process.

Description

technical field [0001] The invention relates to the technical field of oil and gas pipeline building materials, in particular to a corrosion-resistant metal plate. Background technique [0002] With the acceleration of the global industrialization era, the demand for energy is increasing day by day, and the energy issue has become a key issue in the economic development of various countries. Due to the slow progress in the research and development of alternative energy sources, the exploitation of oil and gas fields with strong corrosive media has become a reality. [0003] For the exploitation of oil and gas fields with strong corrosive media, traditional single anti-corrosion technologies and materials such as adding corrosion inhibitors, plastic inner coatings, and corrosion-resistant alloys are used. development needs. In order to reduce mining costs and prolong the service life of pipelines, the use of corrosion-resistant alloy composite plates is one of the relativel...
