1. Intrinsic Corrosion Resistance: The Chromium Advantage

   The remarkable durability of stainless steel stems from its unique composition, primarily the presence of a minimum of 10.5% chromium. This chromium reacts with oxygen to form a thin, passive, self-healing oxide layer on the steel's surface. This passive layer acts as an invisible, impenetrable barrier, protecting the underlying metal from a wide array of corrosive agents.

   Center Enamel leverages various grades of stainless steel:

   • 304/304L: Versatile grade offering excellent general corrosion resistance
   • 316/316L: Enhanced corrosion resistance against chlorides and aggressive chemicals
   • Duplex Stainless Steels (e.g., 2205, 2507): Higher strength and superior resistance to pitting and stress corrosion cracking
2. Unparalleled Hygiene and Purity Preservation

   The smooth, non-porous surface of stainless steel inherently resists bacterial growth, making it ideal for industries where hygiene and product purity are paramount. Stainless steel does not leach contaminants into the stored product, ensuring the integrity and quality of sensitive liquids.

3. Exceptional Structural Integrity and Strength

   Stainless steel boasts an impressive strength-to-weight ratio, allowing for robust tank designs that can withstand significant internal pressures and external environmental forces. Our welded construction ensures a monolithic structure that is highly resistant to impact, seismic activity, and thermal stresses.

• Advanced Welding Techniques: Our highly skilled welding technicians employ advanced techniques such as TIG and MIG welding to ensure high-quality, defect-free seams.
• Rigorous Non-Destructive Testing (NDT): Every welded seam undergoes comprehensive testing including Radiographic Testing, Ultrasonic Testing, Dye Penetrant Testing, and Visual Inspection.
• Passivation and Surface Treatment: After fabrication, our stainless steel tanks undergo passivation process to enhance corrosion resistance. Electropolishing is available for specific applications.

Center Enamel's welded stainless steel tanks are designed and manufactured in strict adherence to leading international standards:

• ASME Boiler and Pressure Vessel Code
• API 650
• AWWA D100/D103
• EN 14015 / EN 1993-4-2 (Eurocode 3)

• Capacity: From smaller process tanks to large-scale industrial storage
• Dimensions & Configuration: Vertical, horizontal, flat-bottomed, dished heads, or custom shapes
• Internal Components: Agitators, heating/cooling coils, baffling, internal ladders, and specialized spray balls
• External Accessories: Specific nozzles, manways, insulation, cladding, and customized support structures
• Surface Finishes: Various internal and external finishes to meet specific requirements

Center Enamel's welded stainless steel tanks are ideal for:

• Chemical Processing
• Food & Beverage
• Pharmaceuticals & Cosmetics
• Oil & Gas
• Water Treatment
• Pulp & Paper
• Biotechnology

While the initial investment in welded stainless steel tanks may be higher than alternative materials, their unparalleled durability, resistance to degradation, and minimal maintenance requirements translate into a significantly lower Total Cost of Ownership (TCO) over their remarkably long lifespan.

Stainless steel is a highly sustainable material - 100% recyclable with a significant portion of new stainless steel produced from recycled content. At the end of its exceptionally long service life, a Center Enamel stainless steel tank can be fully recycled, minimizing waste and contributing to a circular economy.
