Description
Technical field
The present invention relates to a kind of metal surface anti-corrosive technology, more particularly to a kind of anti-corrosive technology of transit joint.
Background technology
Transit joint connects between realizing two different-diameter pipelines, and transit joint is in hydraulic system for connection two
The high-pressure oil pipe of kind different tube diameters.Transit joint is higher to the effect requirements of its antirust due to its specific working environment, existing
Anti-corrosive technology in technology is complex and the effect of antirust is poor.
The content of the invention
【1】Technical problems to be solved
The technical problem to be solved in the present invention is to provide a kind of easy to operate, favorable rust preventing effects, can improve service life
Transit joint anti-corrosive technology.
【2】The technical solution solved the problems, such as
A kind of anti-corrosive technology of transit joint, which is characterized in that comprise the following steps：
A, impurity elimination, by transit joint be placed in pretreatment fluid impregnate 1-2 it is small when；
B, clean, cleaned up the transit joint after immersion with warm water；
C, impregnate, by the transit joint after flushing be placed in antirust solution impregnate 1-2 it is small when, the constituent of antirust solution is
Silicate 5-10g/L, sodium citrate 50-80g/L, sodium nitrate 15-25g/L, zinc sulfate 60-70g/L and excess water；
D, clean, the transit joint after being impregnated in antirust solution is cleaned with giant；
E, dry, the transit joint after cleaning is Tumblied Dry；
F, frosted is handled, and the transit joint outer surface after drying is carried out frosted processing；
G, pack, the transit joint after frosted is packed.
Further, in step a, the treatment fluid is the hydrochloric acid that concentration is 15%, and operating temperature is 30-40 DEG C.
Further, in step c, the constituent of the antirust solution is silicate 8g/L, sodium citrate 60g/L, nitre
Sour sodium 18g/L, zinc sulfate 65g/L and excess water.
【3】Advantageous effect
The anti-corrosive technology of transit joint of the present invention, process is simple and convenient to operate, rust-proof effect and Corrosion Protection are good, energy
The service life for enough improving transit joint is long.
Specific embodiment
The embodiment of the present invention is described in detail below.

In the present embodiment in step a, the treatment fluid is the hydrochloric acid that concentration is 15%, operating temperature 30-40
℃。
In the present embodiment in step c, the constituent of the antirust solution is silicate 8g/L, sodium citrate 60g/L,
Sodium nitrate 18g/L, zinc sulfate 65g/L and excess water.
The anti-corrosive technology of transit joint of the present invention, process is simple and convenient to operate, rust-proof effect and Corrosion Protection are good, energy
The service life for enough improving transit joint is long.
The above is only the preferred embodiment of the present invention, it is noted that for the ordinary skill people of the art
For member, without departing from the technical principles of the invention, several improvements and modifications can also be made, these improvements and modifications
Also it should be regarded as protection scope of the present invention.
