Abrasion Resistance of PE Grades
Abrasion Resistance of PE Grades
(OP)
I am looking into the relative wear resistance of grades of PE. Particularly PE80B, PE80C and PE100. The application is a gold tailings line where the design velocity is 1.9m/s. I have the size consist of the grind. D85 = 80um.
Please advise any technical papers , books, websites where this information may be available.

Check out the Vinidex PE pipe web page on www.vinidex.com.au or obtain a copy of their Polyethylene Pipe Systems technical manual on CD-ROM. Page 26 of the "Materials" discusses the abrasion resistance of their PE pipe products.

What we need is for industry to do some Darmstadt testing to come up with the comparative data. Even so actual pipeline data will only come from pipeline operators.

Rate of wear depends on so very many factors; partical size, flow speed, grain shape, grain hardness,angle of impact, liquid carrying grains,relative corrosion rates, presence of other bodies or air in flow stream,temperature,stress level in wear material,Etc Etc.
Any manufacture who publishes data would then be wide open to claims from unhappy users.
Generally speaking each Industry gains experience in what works and what does not (this assumes that there is a desire to search out the best solution.
Before going too far down any particular road stand back and view the problem objectively. In UK we have polyethylene grades pe1000 pe500 pe300 . The first type is the beast wear material but it is available only in certain sheet sizes and as round bar, but it cannot be welded so of limited use. Type two is similar. Type three is weakest but is available as pipes but these can only be heat welded together . ABS and PVC are still good on abrasion, (but not as good), but available in many forms including pipes which are easily assembled by adhesive ( glue ) but they differ widely on chemical resistance.
Polyurethane is very good for abrasion but no chemical resistance, no heat resistance, and it cannot be glued very easily.
Best of luck. Come back if you need more . Cheers DW

Thanks for all of that. One of my specialities is slurry pipeline design and the application of thermoplastics for pipelines. What I was trying to unearth is if there had been any comparative testing of the two grades of PE used for modern pipelines.
To get actual wear rates the best one could hope for is that there is a mine with a similar grind where the bedrock is of a similar consist.
The customer is about to invest heavily in a tailings line and wants some hand holding, perhaps someone to blame.

By the way I have been advising Eurapipe (formerly Durawills) on appllcations of ABS pipe for twenty odd years in Australia and SE Asia.
The ABS you use is probably from Glynwed Industries(formerly Durapipe)
I have seen some comparative Darmstadt testing that shows ABS has equal wear properties to MDPE.
As you say slurries arent slurries.
