BaoLai Steel Group Highlights Advanced Galvanization Processes and Quality Control in Steel Pipe Manufacturing

BaoLai Steel Group, a manufacturer of galvanized steel pipes, underscores the importance of galvanization in enhancing the durability and longevity of metal products. The galvanization process involves applying a protective zinc coating to steel or iron, which provides resistance against rust and corrosion. This method is crucial for industries requiring reliable and long-lasting metal components.

The company implements stringent quality control measures throughout its production process, ensuring high standards from raw material selection to final product inspection. BaoLai insists on sourcing premium raw materials, specifically zinc ingots with 99 percent zinc content, to guarantee the quality of its hot-dip galvanized pipes. This commitment to quality results in nearly 100 percent customer satisfaction upon delivery.

BaoLai operates five galvanizing lines, including three blow-galvanizing lines and two hoist-galvanizing lines. Blow-galvanizing is used for smaller pipe sizes with less average zinc content, resulting in a smoother surface, while hoist-galvanizing is applied to larger sizes with higher zinc content. These methods cater to diverse industrial needs, offering tailored solutions for various applications.

The hot-dip galvanizing process is divided into three stages: pre-treatment, galvanizing, and post-treatment. The pre-treatment stage involves acid washing to remove rust, water washing to eliminate acid residue, and applying galvanizing auxiliary fluid to prevent oxidation and enhance zinc adhesion. During the galvanizing stage, pipes are lined up, dried, and immersed in zinc fluid to form a protective layer. The post-treatment stage includes cooling, passivation to improve corrosion resistance, water washing, drying, and thorough inspection to meet customer specifications.

Located in Tianjin, China, BaoLai's facility spans approximately 130,000 square meters and offers comprehensive services, including galvanizing processing, hydrostatic testing, threading, grooving, and painting. This one-stop service approach ensures efficiency and reliability for clients in sectors such as water conveyance, oil and gas, and fire fighting.
