In the corrosion-resistant pipe joint structure in which the flange is in contact, a continuous corrosion-resistant coating is applied from the inside of the stopper to several threads of the female thread, and the outer end of the corrosion-resistant core protrudes a predetermined length from the outer end of the joint body. A corrosion-resistant pipe joint structure characterized by: (2) The corrosion-resistant pipe joint structure according to claim 1, wherein the number of internal threads of the joint main body is three more threads than in the conventional embodiment. (3) Claim 1 of the above utility model registration, characterized in that the corrosion-resistant core has a ring-shaped recess formed between it and the flange inside the core body.
Corrosion-resistant pipe joint structure described in section. (4) The corrosion-resistant pipe joint structure according to claim 1, wherein the corrosion-resistant core has an enlarged diameter portion formed outside the core body. (5) The corrosion-resistant pipe joint structure according to claim 4, wherein a tapered portion is formed at the outer end of the expanded diameter portion. (6) Claim 2 of the above utility model registration, characterized in that a resin coating is applied continuously between the stopper and the three female threads on the outside thereof.
Corrosion-resistant pipe joint structure described in section.
