About Us

Shandong Wanhuan Energy Equipment Technology Co., Ltd. is Wanlian Haitong's trading company. The two companies operate as one integrated entity (industry + trade) under the same group. Shandong Wanhuan handles sales and marketing, while Wanlian Haitong handles production and delivery. Both present a unified "Wanlian Haitong" brand to global customers.

Wanlian Haitong is headquartered in Jiayang Industrial Park, Wucheng Economic Development Zone, Dezhou City, Shandong Province, China. We specialize in R&D, manufacturing, and sales of explosion-proof energy equipment. Core products include Explosion-Suppression Skid-Mounted Refueling Units, Explosion-Proof Storage Tanks, Aluminum Honeycomb Explosion-Suppression Raw Material, and the strategic partnership of Zhiming Smart Dispensers.

Wanlian Haitong has established a strategic partnership with Sichuan Zhiming Energy Technology Co., Ltd. ("Zhiming Energy"). Wanlian Haitong handles joint promotion and customized delivery of Zhiming dispensers in explosion-proof energy equipment scenarios; Zhiming Energy handles R&D and production of smart dispensers. Customers can obtain an integrated "explosion-suppression skid + Zhiming smart dispenser" solution from Wanlian Haitong in one stop.

3 core advantages: ① Proprietary core technology self-developed aluminum honeycomb suppression material + 6+ national patents + GB 5908 national flame-arrester standard; ② Full product line explosion-suppression skid + explosion-proof storage tank + aluminum raw material + Zhiming smart dispenser 4 product lines; ③ Industry-trade group advantage factory-direct pricing + 24h on-site response commitment—unmatched by peers.

It is an integrated factory-prefabricated refueling system that combines 8 subsystems (storage tank, dispenser, piping, unloading, monitoring & alarm, fire-fighting, explosion suppression) on 1-2 skid bases. Capacity ranges from 5m³ to 50m³. Internal aluminum honeycomb material blocks flame propagation, suppressing blast force by over 95%. No land permitting required; deployed in 1-3 months.

Based on aluminum honeycomb suppression material: the material forms billions of micron-scale pores (porosity ≥ 95%). When exposed to ignition, it instantly absorbs heat and expands, blocking flame propagation and suppressing blast force by over 95%. Certified by the National Explosion-Proof Test Center, compliant with GB 5908 National Flame-Arrester Standard.

Three series cover all scenarios: Compact 1-10m³ (small sites / small fleets), Standard 20-30m³ (mid-size projects), Large 40-50m³ (large logistics parks / ports). The 150L High-Flow model is a sub-product for buses, logistics fleets, and mining sites requiring ultra-high flow refueling.

Construction sites, mining, logistics parks, bus depots, ports, rail freight yards, emergency rescue, military field operations, remote gas stations, and offshore platforms—anywhere traditional gas stations are impractical and rapid deployment is required.

Three key advantages: ① Rapid deployment — factory-prefabricated, operational in 1-3 months vs. 12-18 months for traditional stations; ② No land permitting — classified as equipment, not construction; ③ Intrinsic safety — explosion-suppression technology prevents blasts at the source, far safer than traditional single-wall steel tanks. Investment cost is only 30-50% of a traditional station.

Standard process: ① Requirements & design 7-15 days; ② Factory prefabrication & testing 30-45 days; ③ Transport & hoisting 5-10 days; ④ Piping connection, commissioning & training 3-7 days. Total: 45-75 days, saving over 80% vs. 12-24 months for traditional stations. Certified: GB 5908 / National Explosion-Proof Test Center Certificate / Pressure Pipeline License / ISO 9001 / ISO 14001 / OHSAS 18001.

Five-layer safety protection: double-wall tank + interlayer monitoring + anti-corrosion coating + anti-overflow sensor + emergency shut-off valve. Integrated liquid-level / temperature / pressure / combustible-gas sensors with 5G / 4G / BeiDou triple-mode communication for 24/7 unmanned remote monitoring. Capacity 5-100m³, compatible with gasoline, diesel, methanol, ethanol, and 10+ chemical feedstocks.

By scenario: ① 5-15m³ for small gas stations / small chemical sites; ② 20-50m³ for mid-size chemical / gas stations; ③ 60-100m³ for large chemical parks / port oil storage; ④ Multi-tank parallel expandable to 1000m³ clusters. All capacities custom-built in 7-15 days.

① Double-wall structure SF double-wall per GB 50156; ② Interlayer leak monitoring 24h vacuum/pressure monitoring, alarm at 0.1% leak; ③ Inner/outer anti-corrosion coating for strong acids/alkalis and high-salt environments; ④ Anti-overflow sensor audible/visual alarm at 95% liquid level; ⑤ Emergency shut-off valve response < 1s, auto-cuts inlet/outlet piping on threshold breach.

10+ media widely supported: ① China-VI gasoline/diesel; ② New-energy methanol/ethanol dedicated tanks; ③ Aviation kerosene; ④ Various chemical feedstocks; ⑤ Strong acids/alkalis with custom PE / PTFE / FRP linings. Multi-media zoned storage in a single tank, no cross-contamination.

By site: ① Above-ground vertical small footprint, easy inspection, low cost, ideal for open sites; ② Above-ground horizontal low center of gravity, wind-resistant, ideal for coastal / high-wind areas; ③ Underground buried hidden, no surface space, winter frost-free, ideal for urban gas stations; ④ Semi-buried balance of concealment and maintenance, ideal for mountainous regions. Wanlian Haitong provides all 4 configurations.

It is Wanlian Haitong's proprietary patented material composed of an aluminum matrix + honeycomb micron-scale pore structure. Porosity ≥ 95%, density 0.4 g/cm³, 6+ national patents. Used as a passive intrinsic-safety explosion-suppression layer inside sealed vessels such as tanks, skids, pipelines, and containers.

Porosity is the ratio of internal pore volume to total volume. ≥ 95% means 95% of the material is micron-scale voids and 5% is aluminum skeleton. On ignition, the voids instantly absorb heat and expand, blocking flame propagation. This metric far exceeds the industry standard (typically 70-80%), and is the core technical advantage of Wanlian Haitong's material.

5 key differences: ① Structure honeycomb micron pores vs. dense metal; ② Density 0.4 g/cm³ vs. 2.7 g/cm³ (6× lighter); ③ Function explosion suppression vs. structural only; ④ Porosity ≥ 95% vs. near zero; ⑤ Patents 6+ national patents vs. generic material. Simply put, ordinary aluminum makes the vessel shell; suppression aluminum is the "fireproof inner lining".

Two mechanisms work together: ① Heat absorption & blocking the 95% pores store air at room temperature; on ignition, air instantly heats and expands, absorbing large amounts of heat and breaking the combustion triangle (fuel + oxygen + ignition source); ② Physical barrier the aluminum skeleton forms a 3D grid that physically blocks flame propagation, reducing blast overpressure by over 95%. Together they suppress explosions at the source.
