High-density polyethylene (HDPE)double-wall corrugated pipe
Black, white, red, green, etc.
Appearance quality: smooth appearance, color uniformity, without
any spacer rupture , bubble, cracking, blockage and scratches on
the inner and outer surface.
Ring stiffness≥8, flexibility: According to the requirements, the
testing force should increase continuously. The sample should be
unloaded when the outer diameter deformation is 30% of the original
diameter along vertical direction. Besides, the inner surface of
the sample should be observed carefully without reverse bending,
cracking or disconnection.
Impact resistance: the test temperature is (0±1)℃, drop weight is
1.0KG , the height of a key down is 2m and the permissible maximum
value of actual batting average TIR is 10%.
