Galvanized steel pipes are a common material in the steel industry. Processed through hot-dip galvanizing, they possess corrosion and wear resistance and are widely used in construction, manufacturing, and other fields. Custom-made galvanized steel pipes refer to a type of galvanized steel pipe customized according to specific requirements.

1. Precision Galvanized Steel Pipes: Precision galvanized steel pipes are a type of custom-made galvanized steel pipe with high manufacturing requirements. During their production, strict control over the dimensional accuracy and surface finish of the steel pipes is necessary to meet the precision requirements of specific industries. Precision galvanized steel pipes are mainly used in automotive manufacturing, aerospace, and other fields for manufacturing high-precision components and pipelines.

2. High-Temperature Galvanized Steel Pipes: High-temperature galvanized steel pipes are a type of custom-made galvanized steel pipe that undergoes special treatment to possess high-temperature resistance. They maintain stable mechanical properties and corrosion resistance in high-temperature environments. High-temperature galvanized steel pipes are widely used in high-temperature pipeline systems in industries such as petrochemicals and power generation to ensure safe pipeline operation and extend service life.

3. Pressure-resistant galvanized steel pipe: Pressure-resistant galvanized steel pipe is a specially designed and processed type of galvanized steel pipe with specific wall thickness and pressure resistance. It is commonly used in pipeline systems for transporting high-pressure fluids or gases, such as industrial gas and oil pipelines. This type of steel pipe can withstand high pressure and has good sealing and corrosion resistance.

4. Anti-corrosion galvanized steel pipe: Anti-corrosion galvanized steel pipe is the most widely used type of specially designed galvanized steel pipe. It undergoes special anti-corrosion treatment, effectively resisting external corrosive factors and extending the service life of the steel pipe. Anti-corrosion galvanized steel pipe is widely used in marine engineering, chemical industry, and environmental protection fields, such as offshore oil platforms and chemical pipelines.

5. Special-shaped galvanized steel pipe: Special-shaped galvanized steel pipe is a type of specially designed and processed galvanized steel pipe according to specific needs. Its cross-sectional shape can be circular, square, rectangular, elliptical, etc., to meet the special requirements of different industries and projects. Special-shaped galvanized steel pipes are commonly used in construction, bridges, and machinery manufacturing, such as stair handrails and supports for mechanical equipment.

The classification of custom-made galvanized steel pipes is mainly based on different requirements and application areas. By customizing galvanized steel pipes, the specific needs of various industries can be met, improving project quality and service life. With continuous technological advancements, the classification of custom-made galvanized steel pipes is constantly expanding to adapt to ever-changing market demands.
