End the Erosion Epidemic: How Delta Ducon Eliminates Wear and Tear in Your Abrasive Conveying System


Removable Wear Back Elbows

For industries handling highly abrasive materials – from the relentless daily grind in cement and mining to the demanding environments of power plants and steel mills – one question eclipses all others: "How do I minimize wear and tear on my pneumatic conveying system components?" The answer isn't a quick fix or a single magic bullet. It's a comprehensive strategy, meticulously engineered and rigorously proven over a century of tackling the toughest materials on Earth.


At Delta Ducon, we don't just understand the problem of abrasion; we've mastered the solutions. We know that every worn elbow, every failed valve, and every unscheduled shutdown translates directly into staggering losses in production, skyrocketing maintenance costs, and a constant battle against the forces of destruction. Our commitment is to eliminate this erosion epidemic, providing solutions that not only last significantly longer than standard options but redefine the very concept of durability in abrasive conveying.



The Science of Survival: Engineering for Extreme Durability


The core of minimizing wear lies in a profound understanding of how abrasive materials interact with conveying components. It's about more than just "harder" materials; it's about intelligent design, optimized flow dynamics, and proprietary material science. Delta Ducon's approach is multi-faceted, targeting wear at every critical point in your system:


1. The Ultimate Barrier: Perma/flo™ Abrasion Resistant Pipe & Elbows


This is where Delta Ducon truly sets the industry standard. Our Perma/flo™ pipe and elbows are not simply an upgrade; they are a revolution in wear resistance. Unlike conventional piping that rapidly succumbs to the constant scouring of abrasive materials, Perma/flo™ is engineered for extreme longevity.


  • Proprietary Material Science: Perma/flo™ components are typically cast from specialized iron alloys, often P-33 chrome iron alloy, achieving remarkable hardness ranges up to 550 BHN (Brinell Hardness Number). To put this in perspective, standard 316 stainless steel is around 140 BHN, and cast grey iron is about 180 BHN. This significantly harder, proprietary material forms an impenetrable barrier against even the most aggressive particles.


  • Optimized Design for Minimized Impact: Wear in conveying lines is most concentrated at bends. Perma/flo™ elbows are available in various configurations, including long-radius designs engineered to reduce the impact angle of abrasive particles, spreading wear over a larger surface. For particularly aggressive applications, our Integral Wear Back (IWB) and Removable Wear Back (RWB) elbow designs provide superior protection in these critical high-wear zones. The RWB design allows for the replacement of only the high-wear section, further reducing maintenance costs and minimizing downtime.


  • Seamless Integration: Perma/flo™ pipe and fittings are easily joined with compression couplings or flanged adapter assemblies, allowing for thermal expansion and seamless connection to existing systems.


By investing in Perma/flo™, you're not just buying pipe; you're buying dramatically reduced system downtime, substantially lower maintenance costs, and the lowest total cost of ownership over the operational lifetime of your system.



2. The Unyielding Guardian: Extreme Duty Rotary Valves


Rotary valves are often the unsung heroes of a pneumatic conveying system, but in abrasive applications, they are also a primary point of wear and potential failure. Delta Ducon’s Extreme Duty Rotary Valves are engineered to withstand continuous operation in the harshest environments.


  • Superior P-33 Alloy Construction: Key components like the rotor and wear shoe are cast from our proprietary P-33 chrome-nickel-iron alloy, offering consistent hardness exceeding 550 Brinell throughout the component. This ensures consistent abrasion resistance even in areas of concentrated contact.


  • Field-Adjustable and Replaceable Wear Components: Our revolutionary design allows for the easy, in-field adjustment and replacement of the rotor and separate wear shoe. This unique feature allows operators to reset factory clearances multiple times without removing the valve from service, dramatically extending operational lifespan and significantly reducing maintenance frequency and cost.


  • Robust Sealing and Bearings: With multiple shaft seal options (e.g., standard packing, cartridge seals, Air Mizer Seals) to optimize performance and prevent leakage, and outboard-mounted bearings protected from material contamination and heat, our rotary valves are built for reliability and longevity.



3. Strategic System Design: Beyond the Components


Minimizing wear isn't just about robust parts; it's about how those parts work together within a precisely engineered system. Delta Ducon’s century of application experience allows us to employ system-wide strategies that reduce wear:

  • Velocity Control: While dense phase conveying is often preferred for abrasives due to lower velocities, our expertise extends to optimizing both dilute and dense phase systems. We carefully calculate and control conveying velocities to ensure they are just above the minimum required to keep material flowing, minimizing particle impact and scouring action without risking plugging.

  • Optimized Flow Paths: We design conveying lines to minimize sharp turns, short radius bends, and unnecessary changes in direction. Where bends are unavoidable, we utilize designs that mitigate wear, like our Perma/flo™ elbows or specialized vortex/pocket-back elbow designs when suitable.

  • Material Introduction & Discharge: Proper material feeding into the conveying line (e.g., with our Rotary Feed technology for consistent, controlled flow) and effective material discharge into receiving vessels are critical for preventing localized wear points and ensuring smooth, non-turbulent flow.
