In the high-intensity manufacturing sectors of Selangor and the Klang Valley, certain industrial processes involve high temperatures combined with corrosive agents that exceed the capabilities of PVC. EKG M&E Sdn Bhd provides Anti-Corrosive Stainless Steel Process Ducts, specifically engineered for heavy-duty extraction in semiconductor fabrication, pharmaceutical manufacturing, and industrial kitchens. Utilizing Grade 304 or Grade 316 steel, these systems provide a non-combustible, chemically resistant, and ultra-durable solution for hazardous process exhaust.
We match the alloy specification to the chemical "aggressiveness" and thermal load of your industrial process.
1. Grade 304: Standard Industrial Protection
Ideal for general manufacturing, commercial kitchens, and environments with high humidity but low acid concentration.
Oxidation Resistance: Provides excellent protection against rust and corrosion in typical indoor/outdoor environments.
Cost-Effective Durability: Offers the structural strength and fire-safety of steel with significantly better longevity than galvanized iron.
2. Grade 316: High-Acidity & Marine Environments
For facilities dealing with high concentrations of chlorides, sulfurous gases, or those located in coastal industrial zones.
Molybdenum Enhancement: Grade 316 contains molybdenum, which specifically prevents "pitting" and "crevice corrosion" caused by aggressive chemicals and salt air.
Pharmaceutical Grade Hygiene: The smooth, non-porous surface prevents bacterial growth and chemical absorption, making it mandatory for sterile processing environments.
3. High-Temperature Process Exhaust
Unlike plastic ducting, stainless steel maintains its structural integrity at extreme temperatures (up to 800°C for short bursts).
Thermal Expansion Management: We engineer the system with specialized bellows and expansion joints to prevent duct warping during rapid heating and cooling cycles.
Fire-Rated Integrity: Naturally non-combustible, our stainless steel ducts act as a critical safety barrier, preventing fire from spreading through the exhaust system.
As an industrial M&E specialist, EKG ensures the structural and chemical integrity of the entire duct run:
TIG Welded Airtight Seams:
For process exhaust involving toxic or flammable vapors, mechanical joints are often insufficient. We utilize TIG (Tungsten Inert Gas) Welding to create continuous, hermetically sealed seams. This ensures zero leakage of hazardous gases into the factory workspace.
Interior Surface Passivation:
Post-fabrication, our ducts undergo a "passivation" process. This chemical treatment removes free iron from the surface and enhances the protective chromium oxide layer, maximizing the steel's natural resistance to chemical attack.
Industrial Flange Integrity:
We utilize heavy-duty stainless steel flanges with specialized Teflon (PTFE) or Viton gaskets. These materials are selected for their ability to remain airtight while resisting degradation from the specific chemicals present in your process exhaust.
| Feature | Galvanized Iron (GI) | EKG Stainless Steel (316) |
| Acid/Chemical Resistance | Low (Corrodes quickly) | High (Molybdenum Protected) |
| Temperature Limit | ~200°C | ~800°C (Short term) |
| Hygienic Properties | Poor (Porous/Rusts) | Excellent (Medical Grade) |
| Fire Safety | Melts/Warps easily | High (Non-Combustible) |
| Mechanical Strength | Moderate | Superior (Heavy-Duty) |
Process-Specific Engineering: we don't just "install pipes." We analyze your process chemistry to determine if Grade 304 or 316 is required, ensuring you don't overspend or under-specify.
Certified Welding Standards: Our fabricators are highly skilled in stainless steel TIG welding, providing the leak-proof integrity required for DOSH and Environmental (DOE) compliance.
Strategic Selangor Support: Based in Kuala Lumpur, we provide site chemical-load audits, stainless steel retrofits for failing GI systems, and professional installation for Malaysia's most demanding industrial facilities.
