Compound steel belt with high temperature resistance and corrosion resistance

Abstract

The invention discloses a compound steel belt with high temperature resistance and corrosion resistance. The compound steel belt comprises an inner layer. A partition layer is fixedly connected with one side of the inner layer. A middle layer is fixedly connected with the side, away from the inner layer, of the partition layer. A buffer belt is fixedly connected with the side, away from the partition layer, of the middle layer. An outer layer is fixedly connected with one side of the buffer belt. A thin film layer is fixedly connected with the side, away from the partition layer, of the inner layer. A corrugated pipe strip is arranged on the side, away from the inner layer, of the thin film layer. An elastic air bag belt, a flexible strip, a graphite layer and a carbon steel layer are arranged, the graphite layer can absorb alkaline or acid substances in corrosive liquid, and therefore the corrosion strength can be reduced; a polyethylene layer which is arranged can play a role in corrosion resistance; a fiber strip and a fiber layer are arranged and can achieve the effects of heat preservation and flame retardance; and a nonwoven fabric layer and a network cloth layer are arranged, the sufficient flame-retardant and high-temperature-resistant effects can be achieved, and therefore the high temperature resistance and the corrosion resistance of the compound steel belt are improved.

Description

technical field [0001] The invention relates to the technical field of composite steel strips, in particular to a composite steel strip with high temperature resistance and corrosion resistance. Background technique [0002] Composite steel strip is a composite material made of carbon steel or low alloy steel as the base layer, and one or both sides of it are continuously coated with a certain thickness of stainless steel by explosion method or other methods. It is often used in the manufacture of petroleum, chemical, seawater desalination, and nuclear industries. Various types of pressure vessels are also used in light industrial machinery, food, cooking utensils, construction, welded pipes, railway passenger cars, medical and health equipment and other industries. [0003] At present, the common composite steel strips on the market mainly use the ladle shell on its surface to resist high temperature, and the thickness of the ladle shell is limited. Once the temperature is ...
