Procure factory-certified sanitary liquid containment, closed loop industrial heat exchangers, and UL/CE compliant heavy smoke ventilation equipment directly from our Shandong production hub.
Civil infrastructure, high-density residential towers, and mission-critical manufacturing facilities are systematically abandoning field-cast concrete and non-reinforced polymer cisterns in favor of high-yield austenitic sectional stainless steel tanks.
Traditional flat-panel tanks experience acute localized tensile stress along welded joints. The proprietary "King Kong" press-formed spherical profile transfers hydrostatic lateral loading outward, converting shear strain into balanced hoop stress that extends shell operational life past 40 years without structural deformation.
Potable water security requires total isolation from microbial colonization and chemical leaching. Sourced with prime virgin food-grade SUS304 and molybdenum-stabilized SUS316L, our modular panels completely block ultraviolet radiation, arresting algae photosynthesis and keeping free chlorine concentrations stable without disinfection byproduct formation.
Exporting pre-assembled volumetric tanks is cost-prohibitive due to excessive maritime container dead-space. Our ODM King Kong methodology utilizes precision cold-stamped modular panels (1000×1000mm, 1000×500mm, and 500×500mm) packed with high density in 20GP/40HQ shipping containers, assembled rapidly on-site via robotic TIG argon arc welding.

Global engineering standards like NFPA 22, EN 12845, and GB50974 have elevated liquid storage integrity from a basic passive container requirement into a mission-critical asset protecting human life, high-tech semiconductor fabs, and mega-power utilities.
Rapid urban migration across Vietnam, Thailand, the Philippines, and Indonesia has strained legacy water lines. In response, municipal planners are retrofitting high-rise towers and municipal booster pumping stations with King Kong SUS304 modular tanks to replace crumbling, algae-infested concrete basins that risk public contamination.
High ambient thermal loads and salty coastal air degrade standard mild-steel or glass-fiber (FRP) tanks within 3 to 7 years. Our molybdenum-enhanced SUS316 and custom enamel-sintered steel tanks resist aggressive chloride pitting in hyper-saline desalination and petrochemical installations across the GCC corridor.
Hyperscale cloud data centers require massive thermal reservoirs for closed-circuit chilled water buffers and open counterflow cooling towers. King Kong water tanks provide 100% rust-free process loops, ensuring zero particulate fouling within precision brazed plate heat exchangers and server liquid-cooling blocks.

Located within North China’s premier HVAC and fluid handling cluster in Dezhou, Shandong, Shandong Fengdun Environmental Technology Co., Ltd. combines heavy hydraulic forming presses, robotic multi-axis welding, and rigorous metallurgical controls under ISO 9001 quality frameworks.
Panels are formed in a single strike using ultra-heavy computer-controlled 1500-ton hydraulic press machines. This single-draw pressing process prevents internal crystalline micro-fissuring and yields consistent panel dimensions for tight site fit-ups.
Joints are bonded on-site using pure 99.999% argon shield gas along with matching high-nickel/chromium filler wires (ER308L / ER316L). This process minimizes the heat-affected zone (HAZ) and prevents intergranular carbide precipitation.
Deep water tanks (above 3m tall) experience substantial base pressures. Our engineers use multi-directional internal SUS304 angle and rod bracing systems to anchor sidewalls against horizontal forces during high-demand pumping cycles.
Every welded joint is chemically treated with industrial-grade pickling and passivation paste to strip heat tint, remove free iron inclusions, and instantly regenerate an ultra-dense chromium oxide (Cr2O3) passive barrier against corrosion.
Fengdun's engineering team provides full parametric 3D CAD modeling, finite element analysis (FEA) reports, and structural seismic load calculations tailored to your local building codes.
From subterranean fire fighting bunkers to rooftop thermal management platforms, explore how our products integrate into real-world civil and industrial facilities.
Commercial shopping complexes, transport hubs, and high-rise developments require dedicated emergency fire water reserves. Our buried underground composite and King Kong stainless steel reservoirs integrate directly with emergency booster pumps, high-flow axial exhaust fans, and 280°C rated fire dampers to deliver a cohesive life-safety package that preserves precious surface parking area.
Industrial manufacturing plants often run intensive thermal processes that require continuous, reliable heat dissipation. Fengdun supplies custom open square counterflow cooling towers and sealed closed-circuit evaporative coolers coupled with low-noise mixed-flow fans and King Kong cold-well makeup buffer tanks to keep chiller systems operating efficiently under extreme summer ambient loads.
Pharmaceutical cleanrooms, beverage bottling plants, and chemical processing facilities demand contamination-free containment before and after Reverse Osmosis (RO) filtration. Our custom SUS316L polished tanks feature sanitary tri-clamp fittings, clean-in-place (CIP) spray balls, and food-grade silicone seals to prevent secondary contamination across high-purity water circuits.
We eliminate international procurement risks through end-to-end metallurgical verification, third-party factory inspection options, and export-compliant protective crating designed for safe multimodal ocean transit.
Every shipment includes 3.1 Mill Test Certificates (MTC) proving authentic chemical alloy breakdown (Ni, Cr, Mo) and mechanical yield properties. We back all raw material sourcing with certified positive material identification (PMI) testing to prevent low-nickel grade substitutions.
We work seamlessly with independent inspection bodies including SGS, Bureau Veritas (BV), Intertek, and TÜV. Global EPC clients can request on-site weld inspections, coating thickness checks, fan balancing tests, and 24-hour hydrostatic leakage tests before cargo release.
Our Dezhou manufacturing plant is strategically located near Qingdao and Tianjin ports. Modular panels are bundled with laser-cut protective film, cushioned with moisture-barrier corrugated foam, and secured inside solid fumigated wooden crates built for ocean freight.

Key design, material, and logistical questions addressed directly by our lead hydraulic and HVAC engineering teams.
Flat sheet panels experience bending deflection and localized stress concentrations along perimeter welds when filled with water. The spherical pressed dome profile of the King Kong panel redirects lateral hydraulic forces into membrane tension across the curved surface, distributing stress evenly to help prevent metal fatigue and weld failure over decades of operation.
SUS304 provides dependable, food-safe performance for general potable water installations where chloride concentrations stay under 200 mg/L. For coastal sites within 5 km of the sea, water supplies with chloride levels exceeding 200 mg/L, or industrial chemical applications, SUS316L is recommended because its 2.0–3.0% molybdenum content helps prevent pitting and crevice corrosion.
We supply fully customized flat-pack kits with pre-cut panels, internal support tie-rods, base channel frames, and pre-flanged nozzles, accompanied by clear 3D assembly drawings, piece-by-piece component numbering, and detailed welding parameter manuals. For large commercial projects, we also offer live video guidance or dispatch experienced welding supervisors directly to the site.
Modular sectional tanks must sit on a level reinforced concrete strip pier or concrete plinth foundation engineered to carry full hydrostatic loads. Parallel concrete beams are typically spaced 500mm or 1000mm on-center, matching panel joint intervals to allow standard structural steel base channels to rest evenly across the foundation without point-load sagging.
We test all tank seams using a multi-step quality control process: visual inspection of root penetration, dye penetrant testing (PT) along internal seams, and a mandatory 24- to 48-hour continuous hydrostatic fill test. For subterranean or specialized tanks, vacuum box bubble leak detection is also conducted on bottom plate weld junctions.
