제품 개요
Galvanized seamless steel pipes are made from solid steel billets that are heated and extruded into shape without welding. After the steel pipes are formed, they are coated with a layer of zinc to prevent corrosion and increase durability. These pipes are highly regarded for their strength, structural integrity, uniform wall thickness and corrosion resistance, making them an ideal choice for demanding applications.

장점
우수한 내식성: The zinc coating acts as a sacrificial layer, preventing the steel from rusting even if the surface is scratched (protected by electroplating). In harsh environments, hot-dip galvanized pipes can last 5-10 times longer than uncoated steel.
High mechanical strength: The seamless structure eliminates weld weak points and has excellent pressure resistance (ideal for high-pressure applications such as oil and gas transportation).
Smooth inner surface: Reduces fluid friction, minimizes pressure loss and scaling, making it suitable for fluid transportation (water, gas, chemicals).
Long service life: Hot-dip galvanized pipes can last up to 20-50 years in mild environments, reducing replacement costs.
환경 친화적: Zinc is non-toxic and recyclable; the galvanizing process meets international environmental standards (e.g., the coating is RoHS-compliant).
Wide application: Suitable for high/low temperature (-40°C to 300°C) and various media (acidic, alkaline or neutral fluids).
Easy installation: Standardized threaded, flanged or grooved ends for direct connection to pipes and structures.
