ABRASION RESISTANCE PROTECTO
401 LINING IN PRODUCTION-RUN DUCTILE IRON PIPE
The abrasion resistance of Protecto 401 was tested
and measured using the European Standard EN 598: 1994-Ductile iron pipe, fittings,
accessories and their joints for sewerage applications-section 7.8 Abrasion Resistance.
This test is also applicable to high alumina cement
mortar lining. The test and results are described as follows:
7.8 Abrasion resistance
The test shall be carried out on a pipe sample 1mm
long, closed at both ends after enclosing the test material; preferred sizes are DN 200
and DN 400.
Before test, the pipe section shall be immersed in
water at ambient temperature for approximately 24h.
The test material shall contain natural sileceous
gravel to reach a level of 38 mm (2mm above the invert) with enough water to reach the
same level. The gravel particle size shall be between 2 mm and 10 mm, with an average size
of approximately 6 mm.
The pipe sample shall be fixed horizontally on a
testing device capable of inclining the sample successively to an angle of plus 22.5 °
and minus 22.5 ° every 3 to 5 sec.
The pipe sample shall be examined after 100,000
cycles; the depth of abrasion shall be the average of 15 measurements taken every 50 mm
along 700 mm of the pipe invert, excluding 150 mm at both ends.
The loss of lining thickness shall be no more than
described in Section 5.7 Abrasion resistance:
Section 5.7 Abrasion resistance
When tested in accordance with 7.8, the pipes shall
not have an abrasion depth greater than 0,6 mm after 100,000 cycles.
Allowable Loss One Hundred Thousand Cycles: .6 mm
(23.6 mils)
Protecto 401 Loss One Million Cycles: .05 mm (2
mils)
This results in a Protecto 401 safety factor of over
100 times the allowable wear for sewer service.
