Abstract
The utility model relates to a bracelet type sacrificial anode which is made into the shape of a half lantern ring. The inner diameter of the half lantern ring is determined by the outer diameter of a pipeline to be protected, and the configuration of the half lantern ring forms a semicylinder shape or a semicylinder shape with conicity at both ends. In the body of the sacrificial anode, reinforcing ribs made of strip steel are arranged in a circumferential direction, and iron cores are arranged in a longitudinal direction. When the bracelet type sacrificial anode is used, two half lantern rings are buckled oppositely on a pipe to be protected, and are welded on the pipe by the iron cores to form a bracelet shape. The utility model has the advantages that the protecting current produced by the bracelet type sacrificial anode is homogeneous and symmetrical, so the efficiency is high; the pipe is wrapped by the sacrificial anode in the bracelet shape, so the pipeline can be installed and operated conveniently.
Description
The utility model belongs to the anticorrosive metal with cathode protection method.Mainly be applicable to the galvanic protection of submerged pipeline.
Sacrificial anode is with electrochemistry cathode protection method protection steel construction uncorroded a kind of method in seawater or other corrosive mediums.With making anode than steel electronegative relatively alloy in medium.Alloy commonly used has aluminium alloy, zinc alloy, magnesium alloy.This anode is connected with protected steel construction, and it is right that the two constitutes galvanic couple, and it is protected that steel construction becomes negative electrode, is not subjected to the burn into anode dissolution, sacrificed.
Common sacrificial anode all is that block, bar-shaped, center has an iron core, is used for being soldered on the protected steel construction.When being used for submerged pipeline, the protective current that is produced is inhomogeneous, asymmetric, protection efficient is low, and hinders operation when pipelining.
The utility model purpose is to provide a kind of and can protects evenly submerged pipeline, and is convenient to the bracelet-shaped sacrificial anode of pipelining.
In order to reach above purpose; the utility model is made half collar shape with sacrificial anode, and the internal diameter of half collar is decided by claimed outer diameter tube, and length is 1-3 times of internal diameter; the thickness protection time limit as requested, the anode gross weight of Ji Suaning decides routinely.The profile of half collar is the semicircle tubular, or the semicircle tubular of double headed roller tapering.In the sacrificial anode body; The stiffening web that has steel band to make in circumferential direction is vertically cored.On the pipe that two and half collars are protected being buckled in, be welded on the pipe in use, form the shape of bracelet with iron core.
Compared with prior art, the utility model has the advantages that: because sacrificial anode is half collar shape, become the bracelet shape during use on pipeline, the protective current that is produced is even, symmetrical, thereby the efficient height.And sacrificial anode becomes the bracelet shape to wrap on the pipe, is convenient to the fitting operation of pipeline.
Now in conjunction with the accompanying drawings, structure of the present utility model is further specified.Accompanying drawing one is the structural representation of the bracelet-shaped sacrificial anode of the utility model, and accompanying drawing 2 is AA sectional views in the accompanying drawing 1.
In the accompanying drawing, 1 is that half cover ring body is cast by sacrificial anode material, the 2nd, and connect iron core and make by Galvanized Steel Strip (5 * 50mm cross section), the 3rd, (50 * 50mm) make stiffening web by Galvanized Steel Strip.Stiffening web 2 is welded into one with iron core 3, when the casting sacrificial anode, gives placing earlier in the mold, and casting back three constitutes an integral body.
Claims (2)
1, a kind of bracelet-shaped sacrificial anode is the sacrificial anode used of protection submerged pipeline, it is characterized by: sacrificial anode be shaped as half collar-shaped.
2, according to the sacrificial anode of claim 1, in the middle of anodic, stiffening web is arranged along circumferential direction.
