May 22, 2017

1.Ductile iron pipe inside and outside surface must be smooth, do not allow cracks, cold and other obstacles, for all wall thickness thinning of the local defects, but its depth shall not exceed (2 +0.05 T) mm, T is pipe wall thickness.

2.Ductile iron pipe flanges spare contour must be clear, not allowed to affect the use of casting defects.

3.If the user agrees, local defects that does not affect the use can be repaired, but the repaired pipe must be re-water pressure or air tightness test.
