Galvanized Pipe
The standard name for hot-dip galvanized steel pipe products is "Hot-Dip Zinc-Coated Welded Steel Pipes for Low-Pressure Fluid Transportation". It is produced by performing internal and external hot-dip galvanizing on welded steel pipes, so that both the inner and outer walls of the pipes are coated with a zinc layer. This greatly improves the corrosion resistance of the steel pipes, which reaches approximately 20 times that of ordinary steel pipes.
Overview
As a conveying pipeline or metal structure, hot-dip galvanized steel pipes are widely used in fire protection engineering, natural gas transportation, petroleum processing industry, water conservancy engineering construction, and residential buildings. This product is used with reference to American ASTM A53, British BS1387, national GB/T3091 and the enterprise's internal control standards, and is not suitable for exposed use in non-neutral environments such as acid, alkali, salt, etc.
Specifications and models: DN15-300MM round pipes; profile processing of hot-dip galvanized square pipes, angles, channel steel, etc.
Excellent Corrosion Resistance:
The hot-dip galvanized layer provides long-term anti-corrosion protection, with a service life over 20 times that of ordinary steel pipes (in neutral environments), effectively resisting moisture, oxidation, and mild corrosive media.
The smooth inner zinc layer reduces scale adhesion and minimizes microbial growth risks, suitable for transporting drinking water, fire water, and other media.
High Strength and Stability:
The welded steel substrate ensures excellent compression and bending resistance, capable of withstanding external impacts during construction and long-term working pressures (e.g., high-pressure fire protection systems).
The galvanized layer and steel substrate are tightly bonded without peeling risks, maintaining structural stability under temperature changes (thermal expansion/contraction) and vibration.
Process and Quality Advantages:
Adopts a fully automated hot-dip galvanizing production line, strictly controlling zinc liquid temperature and immersion time to ensure uniform zinc layer thickness, smooth surface, and no defects such as missing plating or slag accumulation.
Subject to multiple quality checks before delivery, including pressure testing, visual inspection, and dimensional accuracy verification, meeting national and internal control standards.
