Key Product Advantages
1.Superior Sealing and Leak-Proof Performance
The closed-head structure ensures high-integrity containment, preventing leakage and evaporation of volatile materials. Precision-threaded openings accommodate secure bungs or vent caps, guaranteeing airtight protection during long-distance transport.
2.Enhanced Strength and Durability
The straight-wall design offers excellent vertical strength for stacking, while Sifang’s advanced welding technology ensures structural integrity under dynamic load conditions. Reinforced rolling ribs further improve resistance against deformation and impact.
3.High Compatibility with Liquid Products
Designed primarily for liquid or flowable contents, the drum’s sealed top and dual openings provide efficient filling, dispensing, and venting compatibility with automated industrial systems.
4.Corrosion-Resistant Coating Systems
Dual-layer coating protection—exterior weatherproof enamel plus interior chemical-resistant lining—ensures outstanding durability even under harsh chemical or environmental exposure.
5.Flexible Customization Options
Available in multiple capacities, linings, and surface finishes, the drums can be tailored for specific applications including hazardous chemicals, food-grade liquids, or specialty coatings.
6.Environmentally Responsible Manufacturing
Sifang’s shift toward water-based coatings reduces VOC emissions, aligning with international sustainability standards. The steel body is fully recyclable, promoting a circular economy for industrial packaging.
Product Composition and Structure
1.Each Straight-Mouthed Closed Steel Drum consists of
Drum Body: Cylindrical, straight-sided wall constructed from high-strength cold-rolled steel sheets.
Top Head: Permanently welded with precision-threaded openings (2” and ¾”) for filling and venting.
Bottom Plate: Seam-welded and mechanically reinforced for high structural stability.
Coating Layers
Exterior: Amino or water-based paint with high adhesion and weather resistance.
Interior: Lining options tailored for chemical or food-grade compatibility.
Sealing Components: Gaskets, bungs, and plugs with anti-corrosion coating for secure closure.
2.Manufacturing Process
Steel sheets are rolled, welded, and formed with precision-controlled machinery.
Drum bodies and ends are seam-welded to ensure leak-proof performance.
Surface coatings and internal linings are applied through automated spraying and baking systems.
Each drum undergoes thorough testing for dimensional accuracy, coating quality, and sealing performance.
