Center Enamel: A Leading Storage Tank Manufacturer Supporting Global Energy and LNG Infrastructure

Founded as a trailblazer in enamel frit formulation and sheet steel coating technology, Center Enamel has grown into an international heavyweight in containment engineering. Headquartered in Shijiazhuang, China, the manufacturer holds more than 20 patented enameling technologies and operates a world-class production facility spanning over 40,000 square meters.

As global energy demands shift toward cleaner-burning fuels, Center Enamel has strategically expanded its research and manufacturing capabilities. Today, the company designs, fabricates, and installs robust tank solutions that safeguard critical liquid, chemical, and gas resources worldwide.

Storing liquefied gases such as Liquefied Natural Gas (LNG) and Liquefied Petroleum Gas (LPG) demands extreme thermal management and structural integrity.

Because LNG must be maintained at a cryogenic temperature of $-162^\circ\text{C}$ ($-260^\circ\text{F}$) under atmospheric pressure to remain liquid, structural materials must avoid low-temperature embrittlement.

To support this highly demanding sector, Center Enamel delivers specialized, high-capacity tank designs and materials:

Stainless steel remains the gold standard for low-temperature and chemical purity storage. The chromium and nickel content within the alloy creates a natural, self-healing passive oxide layer. This layer prevents rust and maintains its high ductile strength even when exposed to severe temperature drops or aggressive corrosive compounds found in fuel refining and gas-washing processes.

For industrial and cryogenic facilities, storage vessels must align with rigorous global pressure-vessel standards. Center Enamel's industrial welded tanks are engineered to handle high hydrostatic and thermodynamic loads. These designs utilize premium metals, including 9% Nickel steel and specialized stainless alloys, paired with advanced thermal insulation backfills (such as expanded perlite and load-bearing Foamglas blocks) to minimize Boil-Off Gas (BOG) rates.

To serve diverse municipal, industrial, and petrochemical facilities, Center Enamel manufactures several distinct tank configurations:

For international Engineering, Procurement, and Construction (EPC) firms, sourcing storage assets from Center Enamel offers several distinct technical advantages:

• Proprietary Enamel Frit Development: Center Enamel is the only GFS tank manufacturer in China that formulates and bakes its own raw glass frit. This in-house chemical control allows them to customize the glass formula to survive extreme environments—ranging from pH 1 to 14 or highly saline offshore conditions.
• Fully Prefabricated, Modular Delivery: Precision CNC cutting, punching, and coating take place entirely within Center Enamel's state-of-the-art facility. This eliminates risky and time-consuming on-site sandblasting and field-welding, allowing bolted tanks to be erected quickly using a series of hydraulic jacks.
• Strict Quality Control (Holiday Testing): To ensure 100% defect-free surface barriers, GFS panels undergo high-voltage holiday testing at 1500V. This rigorous electrical check guarantees zero microscopic cracks or pinholes in the protective coating.
• Extensive Export Footprint: Bolted and welded systems engineered by Center Enamel are fully approved and trusted in high-regulation markets like the United States, Germany, Australia, and the Middle East, with thousands of successful field installations operating worldwide.

Center Enamel manufactures a broad spectrum of high-capacity stainless steel and welded steel vessels that support industrial gas facilities, including storage for liquified petroleum gas (LPG), refinery chemicals, and process liquids. For highly specialized, large-scale cryogenic LNG projects, their systems are engineered in strict accordance with the material selection, thermal design, and secondary containment rules outlined in API 620 Appendix Q.

Regular epoxy coatings can peel, blister, or suffer from micro-cracking when exposed to UV radiation or temperature swings. Center Enamel's GFS plates feature a physical glass coating that is fused to the steel core at temperatures exceeding 820°C. This creates a completely inorganic, non-porous chemical bond that is physically impervious to UV rays, high surface abrasion, and aggressive chemical corrosion.

Because bolted tanks are modular, the GFS or steel plates can be packed flat and shipped in standard shipping containers. This modular design significantly reduces international shipping volumes and transport costs compared to pre-assembled, cylindrical field-welded tanks.
