Abstract
In a pipe joint where two pipe sections () have threadably engaged end portions (), joint ends () are substantially sealed to each other by a sealing surface () on one pipe section that substantially abuts a sealing surface () on the other pipe section. In one joint, a ring-shaped cutout (, FIG.) is formed in a first pipe section and a ring-shaped spacer () is located in the cutout. The spacer is chosen from several that have slightly different lengths so the spacer end contacts the corresponding sealing surface (). In a pipe string used to carry corrosive fluid, the inner surface () of adjacent pipe sections is covered with a corrosion resistant coating (). Where the sealing surface is connected to a rounded corner (), the coating extends to and along the sealing surfaces (). Where there are sharp corners () at the intersection of the inside surface () with the sealing surface (B,B), the coating does not extend along the sealing surfaces.
