In the heavy industrial sectors of Selangor and the Klang Valley, managing high-temperature process exhaust is a critical engineering challenge. EKG M&E Sdn Bhd provides High-Temperature Industrial Process Ducts, specifically designed for foundries, industrial ovens, steam boilers, and smelting operations. These systems are engineered to maintain structural integrity while transporting air at temperatures ranging from 250°C to over 800°C, preventing duct warping, joint failure, and hazardous radiant heat leakage.
Standard ducting loses its mechanical properties as temperature rises. We select materials and fabrication techniques based on the continuous operating temperature and thermal "shock" cycles of your process.
1. Medium-High Temp (250°C to 450°C) - Ovens and Curing Lines
Common in powder coating and food processing facilities.
Heavy-Gauge Carbon Steel: We utilize 14-gauge to 10-gauge carbon steel. At these temperatures, the metal remains rigid but requires specialized heat-resistant coatings to prevent surface oxidation.
Internal Acoustic & Thermal Liners: For processes requiring noise reduction, we utilize high-density mineral wool liners protected by perforated metal sheets, ensuring the duct is both quiet and thermally efficient.
2. Extreme-High Temp (450°C to 800°C+) - Furnaces and Smelters
In metalworking and glass manufacturing, the exhaust air can be hot enough to melt standard fasteners.
Grade 310/316 Stainless Steel: We specify high-nickel alloys like SS310, which offer superior resistance to "scaling" and oxidation at extreme temperatures.
Refractory Lining Options: For localized "Hot Zones," we can provide refractory-lined ductwork. This ceramic interior acts as a heat shield, protecting the outer metal shell from the most intense thermal loads.
3. Steam and Flue Gas Extraction
High humidity combined with heat creates a highly corrosive "wet-heat" environment.
Grade 316L Stainless Steel: We utilize "Low Carbon" 316L to prevent "intergranular corrosion" at the welds, ensuring the ducting remains leak-proof even when handling corrosive flue gases.
Condensate Management: Our high-temp designs include integrated pitch and drainage points to remove corrosive condensate that forms during system cool-down.
As an industrial M&E specialist, EKG ensures the ducting network is built for thermal safety:
Thermal Expansion Management:
Metals expand significantly at high temperatures. A 10-meter run of steel can expand by several centimeters when heated to 500°C. We integrate Multi-Ply Stainless Steel Bellows or slip-expansion joints to absorb this movement, preventing the duct from buckling or tearing its wall supports.
Radiant Heat Protection (Lagging):
To protect workers and reduce the load on your factory's ambient cooling, we apply High-Temperature Rockwool Lagging (up to 100mm thick) finished with an embossed aluminum or stainless steel jacket. This ensures the external surface remains at a safe "touch temperature" regardless of the internal heat.
Fully Penetrated Welded Joints:
Mechanical seams (like Pittsburgh locks) fail under thermal stress. All EKG high-temperature ducts are Continuous TIG or MIG Welded. We utilize specialized welding rods that match the thermal expansion coefficients of the parent metal, ensuring the joints never crack during heat-up cycles.

| Heat Protection | Basic Fiber Wrap | High-Density Rockwool + Cladding |
| Service Life | Fails rapidly > 90°C | Long-term Stability up to 800°C+ |
Total Thermal Analysis: We don't just "install pipes." We calculate the Thermal Expansion Rates and Radiant Heat Loss for your entire layout, ensuring your building's structural supports are not compromised by heat.
Safety First Engineering: Our designs prioritize worker protection and fire safety, ensuring your facility meets DOSH (JKKP) and BOMBA standards for high-temperature mechanical services.
Strategic Selangor Support: Based in Kuala Lumpur, we provide professional site audits for "warped" or "leaking" high-heat ducts, offering expert retrofits and installation for Malaysia's heavy industrial sector.
