Abstract
The invention discloses a corrosion-resistant end cover. A painting coating which comprises a bottom layer of an ENA300/303 bronze painting coating and a surface layer of an ENA301/303 aluminum white painting coating is arranged at the inner surface of an end cover body. For the end cover, the structure is reasonable, the problem that the inner surface of shell-and-tube heat exchanger is easily corroded by seawater and sea creatures is solved, the cost is greatly lowered, and the energy is saved; and the end cover is mainly applied to shell-and-tube heat exchangers.
Description
Technical field
The invention belongs to the ship machinery field, relate to a kind of heat exchanger, be specifically related to a kind of corrosion-resistant end cap.
Background technology
For the heat exchanger on the ship, when the end cap inner surface was coated with common tar epoxy-based lacquers, inner surface was easily by seawater and marine growth corrosion; For addressing this problem, existing heat exchanger has been equipped with anticorrosion zinc bar in end cap inside, and this is preventing to have played the certain protection effect aspect seawater and the marine growth corrosion; But, because the absorption of seawater scouring and marine growth and deriving destroys painting layer easily; Penetration of sea water causes end cap the corrosion failure phenomenon to occur to inner.
Summary of the invention
Goal of the invention: the objective of the invention is in order to solve the deficiency of prior art, a kind of corrosion-resistant end cap of rational in infrastructure, long service life is provided.
Technical scheme: a kind of corrosion-resistant end cap, comprise the end cap body, be provided with skin of paint in said end cap body internal surface, said skin of paint comprises the ENA301/303 aluminium white enamelled coating on bronze enamelled coating of the ENA300/303 of bottom and top layer.
As preferably, the thickness of the bronze enamelled coating 2 of described ENA300/303, ENA301/303 aluminium white enamelled coating 3 is 120-125um.
Beneficial effect: the present invention is rational in infrastructure, has solved the shell-and-tube exchanger inner surface easily by the problem of seawater and marine growth corrosion, greatly reduces cost, and energy savings is mainly used in shell-and-tube exchanger.
Description of drawings
Accompanying drawing is a structural representation of the present invention.
The specific embodiment
Below in conjunction with embodiment the present invention is described further.
As shown in the figure; A kind of corrosion-resistant end cap; Comprise end cap body 1; Be provided with skin of paint 2 at said end cap body 1 inner surface, said skin of paint 2 comprises the ENA301/303 aluminium white enamelled coating on bronze enamelled coating of the ENA300/303 of bottom and top layer, and the thickness of the bronze enamelled coating 2 of described ENA300/303, ENA301/303 aluminium white enamelled coating 3 is 125um.
