Composed of an alloy of iron and carbon, seamless carbon steel pipe can be bent and formed during the manufacturing process without reducing its high tensile strength. It is important to protect the steel surface from corrosion because the ferritic component can rust due to oxidation from contact with water. Piping that supplies fire sprinkler systems is usually carbon steel, and necessary strength components such as cams and crankshafts in aircraft and automobiles use carbon steel pipes and pipes. Painting carbon steel pipe to effectively avoid corrosion requires the use of the correct primer and paint.
1. Use steel wool to remove all rust on the surface of the seamless carbon steel pipe . Use a hand brush to sweep away any rust to keep the work area free of dust.
2. Use a solvent-based cleaner and a cloth to remove all grease from the pipe surface. Wipe the entire surface of the pipe with a cloth to collect any remaining dust or rust particles. Let the carbon steel dry.
3. Open the zinc phosphate paint primer and stir the primer evenly with a stirring rod. Use a zinc phosphate paint primer because the zinc forms a barrier, acts as an anode during galvanic corrosion and deflects pitting on carbon steel.
4. Apply the primer with a paintbrush, and apply a thick layer on the carbon steel pipe. Let the primer dry according to the manufacturer's instructions.
5. Using a stir stick, mix the urethane acrylic paint until smooth. Apply a coat of paint to the surface of the pipe with a paintbrush. Wipe off any paint that gets into the end of the uninstalled carbon steel pipe to prevent contamination of the pipe.
6. Allow the first coat of paint to dry according to the manufacturer's instructions. Generally, most acrylic paints are ready for follow-up coats after two hours. Finish the job with a final coat of urethane acrylate on the surface of the carbon steel pipe.
Due to the needs of the industry, api carbon seamless pipes should not only pay attention to smooth and bright surfaces, but also pay attention to internal protection. Therefore, during the painting process, corresponding quality inspections should be carried out, and the time should be properly controlled.
Steel pipe wood grain paint
surface treatment
No matter the steel structure is iron pipe, clarinet pipe, aluminum, stainless steel or galvanized pipe, it needs antirust treatment. Pipeline processing schemes are also different, which can be roughly divided into two categories:
1. Rust: Grinding, grinding away the rust spots and unevenness on the surface, requiring smoothness. Then use iron red alkyd anti-rust paint for primary anti-rust, and use epoxy zinc-rich primer for secondary anti-rust after drying. These two kinds of antirust can only be sprayed.
2. No rust: Grinding, grinding off the uneven surface, high flatness requirements, and then spraying one or two layers of epoxy zinc-rich primer. dry out.
Imitation wood grain paint primer construction
Although the anti-rust paint is well done, it is inevitable that there will be dust during the drying process, so we still need to polish the surface when we are making a primer for imitation wood grain paint. The imitation wood grain paint primer can be sprayed or rolled in two coats. Apply one layer thinly, and the second coat should be even, without leaking. dry out.
Imitation wood grain paint surface coating construction
Apply a thin coat with a roller and immediately use a tool to pull out the wood grain. If the steel pipe is relatively long, it needs to be constructed in sections.
Dustproof and waterproof topcoat construction
After the wood grain effect is completed, it needs to be carried out. It is recommended to spray a dustproof and waterproof topcoat to ensure that the surface is even and seamless.
The steel structure is easy to realize in terms of shape, will not be easily corroded, and has outstanding flame retardancy. This is also an important factor why people are keen on steel structure modeling. In fact, the steel structure is not outstanding in appearance, let alone decorative. Usually, if you want to beautify the steel structure, you need to use artistic paint. However, due to the poor adhesion of materials such as stainless steel, there is no way to paint it. Then the use of water-based wood grain paint can solve these problems very well.
