Fire protection steel pipes are widely used in sprinkler systems and fire fighting projects.
To ensure safety and durability, the manufacturing process includes pipe forming, welding, galvanizing, hydrostatic testing, and quality inspection.
This article explains the complete fire protection pipe manufacturing process step by step.
1. Steel Coil Preparation
The manufacturing process begins with steel coils.
The steel coils are uncoiled, leveled, and prepared for pipe forming.
2. Pipe Forming and High-Frequency Welding
The steel strip is formed into round pipes through rolling equipment.
High-frequency welding technology is used to create strong and reliable weld seams.
3. Hot Dip Galvanizing Process
After pipe forming and cleaning, the pipes enter the hot dip galvanizing process.
The galvanized coating improves corrosion resistance and extends service life.
4.Hydrostatic Testing and Inspection
Each fire protection steel pipe undergoes hydrostatic testing and quality inspection.
This helps ensure pressure resistance and product reliability.
5.Packing and Shipment
After inspection, the pipes are packed and prepared for shipment.
Fire protection steel pipes are exported worldwide for construction and fire fighting projects.
