As for galvanized pipe, we can see its characteristics from its name. Nowadays, the utilization rate of galvanized pipe is getting higher and higher, and the requirement is increasing constantly. But we know little about its production common sense. So let's introduce some common sense about galvanized pipe to us by the staff of Beijing galvanized pipe.
Galvanized pipe is actually a kind of anti-rust coating containing zinc on steel. Before coating, it is necessary to remove the rust on the surface of steel. This step directly affects the quality of the coating, and it is very important and crucial. Complete rust removal operation can improve the adhesion of anti-rust coating and prolong the service life of galvanized pipe. If steel is treated by sand blasting, shot blasting or pickling process, its oxide scale and rust can be cleaned up, and the application of anticorrosive coatings can be simpler.
When using sandblasting or manual mechanical rust removal, the surface metal of galvanized pipe is directly exposed to the air due to the falling of iron oxide scale on the surface of galvanized pipe. If a layer of primer is not applied in time, the surface of galvanized pipe is very simple from new rust, which affects the adhesion of the paint film. Although nowadays all kinds of steel pipes are full of shopping malls, and many functions of steel pipes are similar to galvanized pipes, galvanized pipes are always a popular variety. Galvanized pipes are irreplaceable in some respects.
