Production process
Raw Material Preparation
Select high - quality steel coils. Cut and process them into the required round pipe blanks according to specific dimensional requirements.
Production Process
Pipe Forming
Use rolling or welding techniques to process the blanks into round pipes. Welded pipes require precise seam welding, while seamless pipes are formed through hot extrusion or cold extrusion.
Production Process
Surface Treatment
Thoroughly clean the pipes to remove impurities, oil stains, and rust. This step ensures better adhesion of the zinc coating.
Production Process
Galvanization
Immerse the cleaned pipes in molten zinc (hot - dip galvanization) or apply a zinc coating through electroplating. Hot - dip galvanization forms a thick and durable zinc layer, enhancing the corrosion resistance of the pipes.
Production Process
Passivation
Form a passive film on the surface of the galvanized layer through chemical treatment to improve corrosion resistance and weather resistance.
Production Process
Quality Inspection
Strictly inspect the dimensions, surface quality, and corrosion resistance of the pipes. Remove defective products from the production line.
Production Process
Finishing and Packaging
Cut the pipes to the required lengths and then package them properly for storage and transportation.
Production Application
Footwear abrasion solutions
● In the construction field: They are used as scaffolding, structural supports, and water supply and drainage pipes.
● In municipal engineering: Applied to underground drainage, street lamp poles, and greening irrigation.
● In the agricultural field: Serving as the framework of greenhouses and irrigation pipelines, and also used in facilities of livestock farms.
● In the industrial field: Used to build factory workshop supports and act as conveying pipelines, meeting various production requirements.
