b) Delete the dimensional specifications table of nominal outer diameter and nominal wall thickness of steel pipes (see Table 1 of the:2008 edition);
c) The allowable deviation of wall thickness of steel pipes has been changed (see Table 2, Table 3 of the:2008 edition);
d) The normal length range, fixed length and multiple length allowable deviations of steel pipes have been changed (see 6:3:1, 6:3:2:1,:2008 edition)
5:3:1, 5:3:2);
e) The requirements for the full-length curvature of steel pipes have been changed (see 6:4:2, 5:4:2 of the:2008 edition);
f) Changed the terminal shape requirements (see 6:7, 5:7 of the:2008 edition);
g) The requirements for the allowable deviation of the weight of a single steel pipe have been changed (see 6:8:2, 5:8:2 of the:2008 edition);
h) Added ZT750, ZT850, and ZT950 grades, and deleted ZT540 and ZT740 grades (see Table 5, 6:1:1 of the:2008 edition);
i) The content requirements of chemical components P and S elements have been changed (see Table 5, 6:1:2 of the:2008 edition);
j) Changed the smelting method of steel (see 7:2:1, 6:2:1 of the:2008 edition);
k) Changed the requirements for the manufacturing method of tube blanks (see 7:2:2, 6:2:2 of the:2008 edition);
l) The hot extrusion manufacturing method of steel pipes has been deleted (see 6:2:3 of the:2008 edition);
m) Added tensile, impact, and hardness requirements for grades ZT750, ZT850, and ZT950 (see 7:4:1~7:4:3);
n) Changed the tensile strength of brand ZT590, the specified plastic elongation strength, elongation after fracture and sample requirements of ZT520 (see
Table 6,:2008 version of Table 6);
o) Increased the frequency of inspection of size, shape, and surface quality (see Table 8);
p) The batch grouping rules have been changed (see 9:2, 8:2 of the:2008 version);
q) The marking requirements have been changed (see Chapter 10, 9:1 of the:2008 edition):
