Hot-dip galvanized carbon steel pipe is a high-corrosion-resistant pipeline material with excellent anti-rust performance. It features stable mechanical property and strong pressure resistance, solving the problem of ordinary carbon steel pipes being easy to rust in humid and open-air environments.
Our factory adopts high-quality carbon steel pipe as raw material. After high-temperature galvanizing and passivation treatment, the pipe surface is smooth with stable zinc layer adhesion. It effectively resists water erosion, atmospheric corrosion and mild chemical corrosion, greatly extending the service life of the pipeline system.
This product is mainly used for building fire sprinkler systems, municipal water supply pipelines, outdoor buried water delivery projects, factory fire protection piping and corrosive medium conveying pipelines. We support customized zinc layer thickness, fixed-length cutting and pipe end threading. With stable quality and strong anti-corrosion advantages, we provide long-service-life pipeline solutions for global construction and municipal engineering projects.

Key Product Features
Heat-exchanging tubes used in high-pressure boilers (with operating pressures generally above 9.8 MPa and operating temperatures between 450°C and 650°C)
must undergo hydrostatic testing, as well as flaring and flattening tests, on a tube-by-tube basis, and are delivered in a heat-treated condition.
Materials include high-quality carbon structural steel (20G, 20MnG) and alloy structural steel (15CrMoG, 12Cr1MoVG).
Application Scenarios and Industries
It is primarily used in the manufacture of components such as steam boiler piping, superheater tubes, headers, economizers, reheaters, and heat exchangers for high-pressure and higher-pressure applications, and is used in fields such as petrochemicals, power generation equipment, and nuclear power facilities.
