If there is any application under 60 deg C and 25 bar; there will be, on balance, no better performing pipe material than UHMWPE.
It’s that simple.
Specifically, our largest success so far has come through the following processes:
Coal Handling Preparation Plant (CHPP) co-disposal lines:
Dredging requires the displacement of large amounts of sand, a very aggressive process. Simultaneously, being in the sea or ocean environment means that materials need to be corrosion, erosion and marine growth resistant.
Official wear results as provided and commissioned by Shanghai Dredging Corporation:
In addition to this, it is important to note UHMWPE’s surface roughness. It is so smooth that marine growth and barnacles will not grow (0.00022mm), allowing for repeat performances.
Similarly, a thickness change of 3.2 mm in a thinner wall material like steel would result in significant variation of pressure allowances, something that may mean it couldn’t be used again at 15 bar.
Slag is a "natural" by-product of any ore smelting process. It is basically a mixture of metal oxides and silicon dioxides. Slag is the bain of maintenance engineers at smelters for several reasons: firstly it is extremely abrasive, secondly it can be significantly corrosive, and finally it tends to clump together on the wall of most pipe materials (scaling) – meaning a cleaning process has to be undertaken regularly.
UHMWPE is the perfect solution.
Not only is UHMWPE a great balance between corrosion and abrasion resistance, but it is also anti-scaling. The result being larger flows for longer times, and greatly reduced maintenance cycles.
What makes UHMWPE anti-scaling is a mixture of its self-lubricating properties and surface roughness. The oxides cannot get enough grip to clump.
** These cases are just a miniscule portion of the kinds of processes that UHMWPE can optimise for any site, please inquire with us regarding your specific application and we can provide further details of what UHMWPE can do.
