BaoLai Steel Group Details Advanced Galvanization Process for Corrosion-Resistant Steel Pipes
BaoLai Steel Group's comprehensive galvanization manufacturing process ensures high-quality, corrosion-resistant steel pipes with extensive industrial applications.
BaoLai Steel Group, a leading manufacturer of galvanized steel pipes, emphasizes the critical importance of zinc coating in protecting metals from rust and corrosion, significantly extending product durability. The company maintains rigorous quality control measures throughout production, achieving nearly 100% customer satisfaction with its hot-dip galvanized steel pipes designed to withstand extreme environments and provide long service life.
The manufacturing process begins with stringent raw material selection, utilizing zinc ingots with 99% zinc content to ensure optimal galvanizing results. BaoLai operates five specialized galvanizing lines, including three blow-galvanizing lines for smaller pipes with smoother surfaces and two hoist-galvanizing lines for larger pipes requiring higher zinc content. This diversified production capability allows the company to meet various industrial requirements effectively.
The comprehensive galvanization process involves three distinct stages: pre-treatment, galvanizing, and post-treatment. During pre-treatment, pipes undergo acid washing to remove rust, water washing to eliminate acid residue, and application of galvanizing auxiliary fluid to prevent oxidation and enhance zinc adhesion. The galvanizing stage includes lining up and drying to remove moisture before immersing pipes in molten zinc to form protective coatings. Post-treatment involves cooling to solidify zinc layers, passivation to improve corrosion resistance, final washing and drying, and thorough inspection to ensure compliance with customer specifications.
Located in Tianjin, China, BaoLai's 130,000-square-meter facility offers complete processing services including hydrostatic testing, threading, grooving, and painting, providing comprehensive solutions for various industrial applications such as water conveyance, oil and gas transportation, and fire fighting systems. The company's commitment to engineering excellence and competitive pricing positions it as a reliable partner in the global steel industry, serving diverse sectors through quality manufacturing and extensive factory inventory.
