Uncompromising performance in extreme fluid transportation and highly structural environments.
When selecting steel components for municipal grids, deep-well water extraction, or harsh structural load-bearing frames, the physical attributes of a 2 Inch Galvanized Steel Pipe define its utility. A nominal pipe size (NPS) of 2 inches corresponds to an outside diameter (OD) of 2.375 inches (60.3 mm). Our factory manufactures schedule 40 and schedule 80 water pipes with walls designed to handle high pressures (exceeding 2,000 PSI test parameters).
The core strength lies in our material choice: high-grade carbon steel (Q235, Q345, and Q355B). For applications demanding elevated structural capacity, the single bearing capacity of our Q355B structural pipe reaches up to 10 tons—which is 1.5 times that of ordinary carbon steels. By applying a thick, hot-dip galvanized protective outer zinc coating (HDG) of more than 500 g/m² (minimum 70 microns thickness), we secure a normal service life of 15 to 20 years even under continuous exposure to damp soils and highly mineralized tap water.
Hot-dip galvanization on internal and external walls provides corrosion shielding, preventing oxidation inside the fluid channel.
Advanced high-frequency ERW welding ensures wall thickness errors do not exceed ±1mm, keeping couplings tight and leak-free.
Multi-purpose design allows immediate configuration as water supply lines or structural load-bearing scaffolding components.
Our 2-inch galvanized pipes are engineered to solve installation and delivery hurdles across diverse operational domains:
Meeting global structural standards through independent verification and strict quality control.
The ring lock scaffolding and heavy-duty steel pipe inventory of Zhuozhan Industry has passed multiple international quality certifications (such as EN 12810/12811, ISO 9001). This ensures every batch leaves the factory with consistent chemical compositions and mechanical properties.
Our structural pipes utilize high-strength hot-dip galvanized steel, featuring strong corrosion resistance, rigid nodes, and a highly stable overall structure. The modular nature translates to quick field installation and convenient disassembly.
Our pedigree is built on successful partnerships with large state-owned enterprises (such as China Construction Eighth Engineering Division and China Construction Fourth Engineering Division). We are ready to tackle complex commercial infrastructure tasks.
A transparent look at our factory manufacturing flow, showing how we reduce surface impurities and ensure product precision.
This is the first step in steel pipe processing. High-precision mechanical cutters slice raw coils into predetermined lengths. During this process, noise (N) and solid waste (S) are systematically collected and recycled.
Following cutting, the pipe body enters the automated punching workstation to create keyholes or coupling connections. This phase generates noise (N) and solid waste (S), which are captured by environmental suppression setups.
Welding machines fuse the carbon steel pipe body with components like locking discs. This process creates high-strength nodes while generating noise (N), waste gas (G), and solid waste (S). Multi-stage filtration plants exhaust clean air.
Raw welded components are transferred to our hot-dip galvanizing plant. Cleaned in an acid pickling bath, the pipe is submerged in 450°C molten zinc, creating a tough iron-zinc alloy layer.
Each pipe undergoes visual inspections, thread sizing tests, and pressure checks before heading to our storage yards for distribution.
How our strategic location, production volume, and logistical setup benefit international supply chains.
As a source factory covering 40,000 square meters, our facility manages an annual production capacity exceeding 200,000 tons, ensuring prompt delivery of large-scale bulk orders.
Our plant sits near three major commercial deep-water hubs: Jingtang Port, Tianjin Port, and Caofeidian Port, reducing inland freight costs and transit times.
Backed by 15 national patents and a dedicated engineering design team, we custom-tailor pipe lengths, thread pitches, and chemical compositions for specific projects.
We run fourteen automated production lines and support partners with a team of 200+ specialists. We resolve logistics issues and technical queries within 24 hours.

How we integrate resource efficiency with advanced anti-corrosion chemistry.
As an engineering-driven metal manufacturer, Zhuozhan Group prioritizes clean, energy-efficient operations. We have updated our pickling and annealing systems to limit solid waste and capture carbon compounds before neutralization.
Our technical research focuses on zinc-aluminum-magnesium alloy coatings. This alternative coating provides self-healing edges and extends pipe lifespan in saline coastal zones by up to 25%, offering reliable performance for deep-sea installations.
Our updated quality assurance setup features non-destructive ultrasonic testing. This enables us to inspect weld integrity along the entire longitudinal axis of our 2-inch galvanized pipes, maintaining strict dimensional consistency and eliminating thin wall vulnerabilities.
Proven reliability in high-load municipal projects, civil infrastructure, and heavy industrial facilities.
Our galvanized steel piping handles high salinity and corrosive sea winds, protecting crucial utilities at major maritime terminals.
Structural pipes and high-capacity supports used to stabilize temporary diversion channels during critical masonry work.
Heavy-duty structural framework and pipes supplied to shore up complex underground excavation works.
Extensive network of utility conduits, service piping, and structural load frames integrated across cleanroom manufacturing plants.
Suspended staging and support pipes deployed over high-flow river channels to protect renovation workers.
Specialized alloy configurations designed to protect piping systems from salt crusting in deep-water ballast tanks.
Direct technical answers from our engineering support team regarding sizes, standards, and uses.
For all ASTM and EN standard pipes, the nominal 2-inch water pipe features an outside diameter (OD) of 2.375 inches (60.3 mm). The internal diameter depends on the selected wall thickness class (such as Schedule 40, Schedule 80, or custom 3.25mm specifications).
We mainly use structural and fluid carbon steels, including Q235, Q345, and Q355B. Q355B is selected for high-pressure installations or heavy structural applications because of its excellent yield strength, supporting up to 10 tons of load per point.
Under typical conditions (municipal water carriage or standard open-air structures), our minimum 70-micron zinc layer prevents rust for 15 to 20 years. In marine areas or damp soil, the expected service life is approximately 10 to 15 years.
Our pipe and structural components are manufactured under ISO 9001 and comply with EN 12810, EN 12811, and BS 1387 requirements. This ensures consistent mechanical properties, reliable tensile limits, and secure weld lines.
Yes. As an OEM/ODM source manufacturer, we supply custom pipes cut to length, with options for threaded ends (NPT/BSPT), grooved endings, or plain ends suited for coupler systems.
We check raw materials, test weld line integrity with non-destructive methods, measure wall thicknesses, and verify chemical properties in our labs. We also conduct hydrostatic tests to ensure our water pipes remain leak-free under pressure.
