8	Surface Quality of Steel Pipe	Internal and external surface of pipe should be slick. Folding crack, delamination and lap weld are not permitted. Other defects that no more than the negative deviance of wall thickness are permitted. Internal burr is allowed to exist. Steel pipe with >100mm, could be repaired for its defects and carry out water pressure experiment. Galvanized steel pipe should carry out homogenization experiment for its galvanization layer. Steel pipe sample should not turn red after 5 times of consecutive immersing in cupric sulfate solution (color of copper plating). There should be complete galvanized layer on both the internal and external surface of the pipe, and should not have the black spot and bubble that characterized the ungalvaniztion. Little coarse surface and existence of sectional zinc hump are allowed.
