REDOX hydraulic pipes are MACHINED and are free of rust causing chemical residues found in pickled pipe.

REDOX pipes do more than meet Standards: they deliver up-time and profit.

 

Continuous Quality Improvement

These 1000x electron microscope images say a thousand words about our commitment to quality. Comparing these images allow you to see why REDOX outperforms the competition:

 

REDOX: Note the smooth surface. There are no places for particles to hide during flushing: there are no particles.

 

Zinc Phosphate D.I.N.: Note the particle size range: 5 – 15 microns: one of the most destructive I.S.O. range sizes for hydraulic components.
The zinc phosphate crystals’ bond to the tube will break on the tension side of bends. Further contamination occurs as the scrubbing force of hydraulic oil changing direction at 15 feet per second abrades the remaining zinc phosphate.

 

Pickled & Oiled Pipe: Note the etched base metal. Pipe treated with corrosives becomes reactive. Reactive surfaces interact with oil additives, inhibiting their lubricating qualities.
Rust reformation occurs on the I.D. of pickled pipe in operating system using hydraulic oil. Our Video, Rust Never Sleeps, explains this process more fully.

Four decades of Continuous Quality Improvement has produced the most reliable pipe delivering clean fluid power for your system.

 

 

 

Each of these Continuous Quality Improvements play a critical role in reducing filtration and flushing costs.

 

Filtration

No hydraulic component should fail in your system if given clean hydraulic oil. Knowing this is important: acting on this knowledge can be a game changer.
Filters are designed to remove particles generated by moving parts; not unlimited particles generated by:

• Pickled pipe
• Zinc phosphate crystals from D.I.N. tubing.

 

Pickled pipe contains a non-reversible / non-flushable danger: a chemically activated surface. Activated surfaces chemically react with lubricant additives, degrading lubricity. This allows metal to metal contact to occur, damaging critical surfaces and generating additional particles.
Also, pickled pipe’s etched surface at the metal grain boundaries can hold enormous amounts of < 15 micron size particles. Particles accumulate in the low pressure zones created by etching. They accumulate until there is a system shock. Shock waves will release a killer cloud of particles downstream, damaging components and overwhelming even the highest beta ratio filters.

Zinc phosphate crystals foster a different kind of contamination: silt. Silt particles are < 2 microns in size. They can hide undisturbed in low pressure zones created by zinc phosphate crystals protruding into the fluid stream. They too, respond to system shock, releasing enormous amounts of particles downstream.
Silt particles are difficult to filter. Component degradation failure is common with silt particles due to their size acting as lapping compounds, degrading critical surfaces in your components.

But, REDOX’s surface is clean, smooth and generates no particles, giving your components nothing but clean hydraulic oil.

 

Flushing

All hydraulic systems need to be flushed prior to start-up. Flushing has limits. Knowing what is happening within your plumbing is important.
There is a direct link between the efficiency of the flush and the operating performance of the system. A few different flushing examples are:

• Pickled and oil systems oftentimes take significant time and money to flush away poorly bonded rust particles. They also have chronic problem that cannot be flushed away: chemically activated surfaces creating lubricity issues. Re-rusting can be a problem too as documented in our video below: Rust Never Sleeps.

• Zinc phosphate D.I.N. tubing does not contain rust, thus it should quickly flush. However, zinc phosphate crystals are a foreign object in the fluid stream that will cause a variety of problems. The first is the crystal structure being stretched and breaking away from the tube at the bends. The second is the remaining crystal structure creating low pressure zones at the surface that trap silt size particles that can degrade critical surfaces of your components.

• REDOX pipes contain none of the issues associated with pickle & oiled pipe or zinc phosphate
D.I.N. tubing, nor does it contribute any other particle to the fluid. Flushing REDOX is both fast and effective.

 

REDOX out-flushes competing systems in both time and results. Our systems consistently drop one I.S.O. range number per every couple of minutes during flushing.

Our focus on creating the cleanest and most cost effective pipe to connect your components, gives you years of up-time and profitability.

 

 

 

Welding

REDOX pipes are engineered to resist scale formation during welding. Vapor Space Inhibiting Oils, like WD 40, are used to create a welding atmosphere that resists scale formation. Below is scale removed from pickled & oiled pipe after welding:

Scale is hard and brittle. When it breaks free it shatters into tiny flat particles that act like razor blades.

Ask our engineers how integrating scale resistant welding procedures can save you money and produce an exceptional product.
Vapor Space Inhibiting Oils do more than resist scale formation. They also:

• Protect pipe against rust formation better than heavy oil: ASTM D4174 Sections 7.1.2.1 and 9.1.1.2.
• Vapor Space Inhibiting Oils impart corrosion resistance to hydraulic oil: ASTM D4174 Section 7.1.3.
• Are useful in hydro sealing components for storage: ASTM D4174 Section 9.1.1.3. Ask our engineers for details.

 

Choice

PDI sells REDOX to hydraulic installers and fabricates REDOX hydraulic spools for installation. PDI has the home court advantage in producing REDOX hydraulic spools:

• Manufacturing in a well equipped shop is more cost effective than field fabrication.
• PDI is a vertically integrated supplier of hydraulic systems. We own and operate the REDOX technology, giving us the ability to quickly respond to your needs.
• PDI is an infra-structure company using 3D software that quickly lays out a schematic of your system.
• A schematic drawing enables us to give you a hard number for manufacturing and installing REDOX spools.
• Machining REDOX in the building where spools are manufactured eliminates trucking costs and gives faster turnaround.
• Welded spools are hydro tested and flushed in-house, eliminating the costs of field testing.
• Spools are purged with nitrogen prior to sealing and in-house painting.
• We also manufacture spools for lube oil, fuel oil and other distillates.
• We install what we build at a guaranteed price.
