The testing of complete plates (70mm X 50mm X 5mm thick) towiredspace.wits.ac.za/jspui/bitstream/10539/16761/10/Freinkel D M... · The testing of complete plates (70mm X 50mm X 5mm

The testing of complete plates (70mm X 50mm X 5mm thick) to

simulate the erosion surface would show if the surface profile

was real or if it was a result of edge effects.

Two types of surfaces were useds

a) Complete oval plates that completely filled the cross

section of the pipe at 45 degrees were used to give an

idea of the overall wear in the pipe. These tests were

conducted in 2 horizontal-horizontal bends and 1

horizontal-vertical bend.

b) 70nra X 50mm plates, protected on the edges by 10mm wide

mild steel strips. The plates were mounted on the sama

specimen holder as the smaller specimens The size of

these plates was specifically chosen to simulate the

area of the test specimens cnce placed in the pipe.

Both types of surfaces were tested under the same conveying

parameters as for the smaller individual specimens.

The profiles were recorded using a customised universal

measuring machine. The results were plotted using the SAS

(Statistical Analysis System) on the mainframe computer at the

University of the Witwatersrand.

Computer generated surface profile of a 70mm by 50 mm mild

steel plate.

\

It can be seen that there is a profile across the plates, but

not as accentuated as with individual samples. Further it was

decided that because the WC-Co specimens would not deform

plastically like the mild steel specimens, edge effects would

not be too detrimental to the repeatability of the t e t s . The

oval plate profile tests were not successful as the computer

tended to generate a rectangular output for an oval input.

The variance displayed by these graphs was well within the

expected error band and therefore it was decided that it would

be an acceptable testing configuration.

APPENDIX F

SCATTER GRAPHS

These graphs represent the scatter for each set of three tests

conducted for each conveying condition. It can be seen that

the difference in erosion follows the same trend for each

sample. It is thought that the degradation of the erosive from

test to test contributed to this effect.
