Stainless Steel Pneumatic Transfer Ducts

Stainless Steel Pneumatic Transfer Ducts by EKG M&E Sdn Bhd

In the high-precision manufacturing sectors of Kuala Lumpur, Selangor, and Nilai—particularly within pharmaceutical, food processing, and specialty chemical industries—Stainless Steel Pneumatic Transfer Ducts are the mandatory standard. These systems are engineered to move bulk solids with zero risk of oxidation, chemical reaction, or batch cross-contamination. Unlike galvanized steel, stainless steel (Grade 304 or 316) provides a non-porous, "passive" surface that is essential for maintaining product purity and surviving aggressive wash-down protocols.

EKG M&E Sdn Bhd specializes in the precision fabrication of hygienic pneumatic networks, ensuring compliance with GMP (Good Manufacturing Practice), DOSH safety standards, and EECA 2024 energy mandates.

Engineering for Purity and Performance

The choice of stainless steel is only the first step; the "finish" and joint integrity dictate the system's long-term success.

1. Grade 304 vs. 316 Selection

• Grade 304: The standard for most food-grade applications and grain transport. It offers excellent corrosion resistance for organic materials.

• Grade 316 (Marine/Chemical Grade): Utilized for corrosive chemical powders, saline environments, or pharmaceuticals that require frequent sterilization with aggressive cleaning agents.

2. Sanitary Internal Finishes (RA Values)

For pneumatic transfer, the internal surface must be ultra-smooth to prevent "product hold-up" (residual powder sticking to the walls).

• 2B Mill Finish: The standard industrial finish.

• Bead-Blasted or Mirror Polish: We provide specialized internal polishing to specific RA (Roughness Average) values to ensure the ducting is self-cleaning and prevents the growth of bacteria or mold.

3. Hygienic Joint Systems

We avoid mechanical fasteners that could harbor contaminants.

• Tri-Clamp / Ferrule Connections: Ideal for systems requiring frequent disassembly for cleaning. These utilize a food-grade silicone or EPDM gasket and a quick-release clamp.

• Orbital Welding: For permanent installations, we utilize automated orbital welding to ensure a 100% penetrated, "crevice-free" joint that is internally flush.

Critical Operational & Safety Benefits

As a specialized M&E contractor, EKG ensures your stainless steel system supports both hygiene and the bottom line:

• TNB Energy Efficiency (Friction Reduction):

  Stainless steel has a lower friction coefficient than galvanized steel. By utilizing "glass-smooth" internal bores and Variable Frequency Drives (VFDs), we minimize the energy required to maintain Minimum Transport Velocity. This directly reduces your monthly TNB electricity bill.

• Anti-Static & ATEX Safety:

  Moving dry powders through stainless steel can generate high static charges. We ensure the entire network is electrically bonded and grounded to prevent sparks. For combustible dusts, we integrate Explosion Isolation Valves to protect your facility.

• Long-Radius "Product-Safe" Elbows:

  To prevent "smearing" or degradation of fragile products (like milk powder or plastic pellets), we utilize Long-Radius Sweeps. This allows the product to glide through turns using centrifugal force rather than impacting the wall at high speed.
