Choose metal pipeline, there is a little defect is very obvious, is easy to rust, especially the inner wall rust is very unfavorable, the inner wall of the pipeline how to remove rust and corrosion? Let's take a look.
1. First into the rusty pipe into the right amount of rust remover, block the other end of the pipe, fully shake several times, let the rust remover and the inner wall of the rusty part of full contact reaction, and then stand for 2 hours or so, it will be poured out, this time the basic rust stains will be cleared.
2. Pour water into the pipe and wash it clean. Rinse it several times and then dry it.
3. Wait until the internal moisture is dry, pour the amine cured epoxy resin coating into the pipeline, also block the other end, and then roll and shake evenly, to ensure that the coating will be coated evenly inside, so that dry will form a layer of anti-corrosion film, to prevent rust and corrosion and other problems.
4. Sand blasting rust removal
Sandblasting is a more advanced way to remove rust. Through special materials, it can remove the rust layer on the outer wall of the pipeline, and remove some paint and dirt with poor adhesion effect.
1, manual rust removal
A lot of the outer wall of metal pipe because of long-term water, acid, alkali and other physical contact with the outside world, the surface will have a thick layer of rust layer, if do not pay attention to clean, the larger effects on the pipe wall will, we can use a hammer, tapping the rust layer can fall off large, for more stubborn rust layer, can be repeatedly with wire brush, and coarse cloth to wipe, You can wipe it off, and then you can see the original metallic color.
2, mechanical rust removal
For the rust of the outer wall of the chemical metal pipe, mechanical rust removal can be adopted. There are special tools for rust removal, which can be used to remove rust on any metal surface, and will not cause damage to the pipe.
Cangzhou Shenlong pipe is the material run sandblasting rust removal method, fast speed, good effect, can reach SA2.5 level, our steel pipe products inside and outside the surface before coating, will use sandblasting rust removal method, in order to achieve a good anti-corrosion effect.
