Technical field
The present invention relates to pipeline corrosion protection field more particularly to aerial pipeline corrosion-resistant fields.
Background technique
Currently, natural gas is one of most commonly used energy in people's daily life, especially in city, natural gas
Using people's lives bring great convenience is given, since natural gas belongs to dangerous goods, so being centrally stored in natural gas
In standing, it is pipelined in user family and is carried out again using heating etc. is also required to be pipelined to and make in addition to natural gas
With place, this requires convey pipeline used reliable enough must just can ensure that conveying is normal.
The substances such as pipeline natural gas, heating largely facilitate people's lives, but its reliability and peace
Full property is an issues that need special attention of having to, and the corrosion of pipeline directly affects the reliability and safety of conveying, pipe
Road is embedded in underground a bit, and some then make somebody a mere figurehead arrangement, and the corrosion factor for being embedded in underground has soil property, moisture, pH value, microorganism
Deng, and overhead corrosion factor has weathering, ultraviolet light, pH value, rainwater etc., it can be seen that the corrosion factor of two kinds of situations is simultaneously endless
Exactly the same, difference, along with arrangement itself has larger difference, therefore cannot use identical anti-corrosion measure, and
Pipeline corrosion protection measure mostly at present.
It is directed to the major measure of pipeline corrosion protection at present, used for being embedded in the pipeline of underground mostly, such as a kind of pipeline
Anticorrosion structure (CN201720916044.8) avoids pipeline from contacting with pipe pier by conduit saddle plate, solves the corrosion at pipe pier and asks
Topic, these measures are suitable only for underground buried tube, are difficult to apply on aerial pipeline, still have at present to the anti-corrosion with aerial pipeline compared with
Big research space, needs related fields researcher and carries out correlative study, cover the shortage.

(1) line treatment: being derusted and cleaned to pipeline surfaces externally and internally, removal rusty stain and other spot impurity；
(2) anticorrosion with painting loses layer: preparing anticorrosive coating according to the component ratio, anticorrosive coating is sprayed at defeated
Pipe surface is sent, it is repeated multiple times to spray the corrosion-resistant coating for forming high quality；
(3) insulating layer and protective layer are set: being wrapped in pipeline with insulating layer, is then wrapped in insulating layer with protective layer again
Outside, using its elasticity, protective layer is made to be close to insulating layer；
(4) wind radiation protective layer: aluminium foil uvioresistant anti-corrosion Cold winding band viscosity is stronger, is wound on the protection layer,
It is pasted tightly not fall off on the protection layer；
(5) it makes outer corrosion-resistant coating: two component of a, b for forming epoxy resin being mixed according to 3 to 1 ratio, stirring is equal
It is even, and rapid application forms outer corrosion-resistant coating in radiation protective layer surface before it is solidified after solidification；
(6) bed course is set: in the position that pipeline is contacted with other objects, bed course being placed between pipeline and contactant.
Beneficial effects of the present invention: (1) construction technology is simple, and material therefor is cheap, at low cost；(2) outer corrosion-resistant coating
Setting protects radiation protective layer, avoids radiation protective layer from being corroded by the external world, and outer anticorrosion is transparent, does not influence radiation protective layer effect；
(3) using the anticorrosive coating voluntarily prepared, it is more preferable to be formed by corrosion-resistant coating anti-corrosion effect；(4) presence of bed course avoids
Tube contacts to object it is corroded.
