Welded Steel Pipe Surface Can Be Painted Like This
In Standard, the coating on welded steel pipe surface area treatment, constantly explore and summarize the constant advancement of steel surface area treatment. Begin with Clearing. Attempt to clear surface area of the steel by emulsification to clear steel surface area and get rid of essential oil, similar matters ,grease and dirt,
Next is device derusting. With brush devices to polish steel surface area, we can get rid of loose tilt or rust, oxidation, and so on. Typically, hand devices can achieve Sa2 Degree derusting and energy device can achieve degree 3.
3rd is the acid pickling procedure. There are two principal procedures that can be utilized to make substance and electrolytic pickling procedure, pipeline corrosion only utilizing chemical etching to get rid of oxide, rust, older coating and so on. Attention! Anchor pattern is simple to induce atmospheric air pollution although substance clearing can achieve a specific quantity of surface area cleanliness and roughness.
4th is the use of higher-energy engine motor rotating blade spraying shooting spray for clearing rust. Washing can get rid of oxides, rust, dirt and large-scale abrasive tube and the Impact of friction.
