PVC pipe threading is marked by the outer diameter of the pipe, standard pipe 16,203,240 is the nominal outer Path, in line with national standards JG 3050-1998, depending on the thickness, different inner diameter and wall thickness of conventional PVC pipe threading type A thicker type, B-type general-purpose, C-type thin-walled three. General Engineering use the most is the B-tube.
