Stop Wear and Tear: Why PERMA/flo Pipe & Fittings Offer Extreme Abrasion Resistance

Delta Ducon perma flo pipe and fittings

Focus: PERMA/flo Pipe & Fittings


Goal: Establish Delta Ducon as the expert in piping longevity and demonstrate the technical superiority of your proprietary cast alloy over standard materials.


The Pipe Failure Problem in Pneumatic Conveying


In systems handling highly abrasive materials like cement, fly ash, or silica, pipe components—especially elbows and bends—are constantly subject to the wearing action of transported solids. Standard carbon steel or even stainless steel pipe can require frequent replacement, leading to:


  • Excessive maintenance budgets and labor costs.

  • Unscheduled system shutdowns and lost production time.

  • Compromised system integrity due to thinning pipe walls.


Delta Ducon’s PERMA/flo Pipe & Fittings were specifically engineered to withstand this continuous erosion, providing longevity far beyond conventional materials.


The Technical Superiority of Cast Alloy


The PERMA/flo difference is in the core metallurgy. Unlike standard industrial pipes, your fittings are cast from proprietary iron alloys designed to achieve a massive increase in hardness:

Material Comparison

Typical Hardness (BHN)

Standard 316 Stainless Steel

140 BHN

Cast Grey Iron

180 BHN

Delta Ducon PERMA/flo

Up to 550 BHN

This extreme increase in Brinell Hardness Number (BHN) allows the PERMA/flo components to dramatically outperform other options in severe abrasive service.


Design Features for Durability and Installation


The PERMA/flo line is designed not just for hardness, but for efficient installation and maximum useful life:

  • Cast Construction: The heavy cast alloy is used for items like elbows (400-450 BHN) and other fittings to resist wear precisely where it is most severe.

  • Elbow and other Options: A wide range of fittings are available to meet specific application needs, including:

    • 90 degree IWB (Integral Wear Back)

    • 90 degree RWB (Removable Wear Back)

    • Impact Style 90 degree RWB

    • 45 degree and 22.5 degree elbows.

    • 45 degree Lateral

    • 90 degree Tees

    • Target Boxes

  • Easy Installation: PERMA/flo Pipe & Fittings are joined together using compression couplings. These couplings facilitate up to 4 degree of deflection, allowing for minor alignment errors and accommodating thermal expansion.


📞 End Pipe Failure—Upgrade to PERMA/flo


Stop treating pipe failure as an unavoidable operational cost. Specifying PERMA/flo is an investment that converts a high-maintenance expense into a reliable, long-term asset.
