Technology is introduced: High-quality phosphating treatment on the inner and outer surfaces of précision bright seamless steel pipe; forming a uniform and dense crystal structure, obtaining a phosphating protective film with high Wear résistance,high corrosion résistance and uniform color; after phosphating then immersing spécial anti-rust oil, the formed phosphating film layer is fine, lubricious, beautiful in appearance, and superior in corrosion résistance and rust prévention.
Features: Phosphating film and steel pipe are a tightly integrated whole structure with porosity, so that sealants, coatings can penetrate into these pores, and tightly combine with the phosphate film, the coated phosphate film is porous. Uniform and fine, the coating penetrates into the pores, greatly increasing and improving the adhésion and gloss saturation of the coating.
Application industry: Widely used in engineering machinery, shipbuilding, précision machinery, hydraulic system and other industries. The surface of phosphating précision seamless steel pipe is especially suitable for painting or spray coating. The paint surface has strong adhésion, excellent effect and beautiful ,anti rust effect Greatly strengthened.
