ABSTRACT:
In a pipe joint made of resin in accordance with the present invention, a primary sealing is formed between an inner ring pressingly inserted into an insertion portion of a pipe at its one end to increase the diameter thereof, and the joint body into which the insertion portion of the pipe increased in diameter, is being inserted. When the threaded connection of a pushing ring to the joint body is advanced, a sealing force is applied to the primary sealing. The inner ring has an inner diameter equal to that of the joint body and that of the pipe, assuring a smooth movement of a fluid in the pipe without the fluid remaining at the joint.
