Zusammenfassung:	PURPOSE:To obtain a pipe joint for joining high corrosion resistant stainless steel to Ti by forming Ta as a joint medium for first and second tubular members and forming alloys of the tubular members and the joint medium at prescribed intervals in the joint medium of the interface between the first tubular member and the joint medium. CONSTITUTION:A Ta plate of the joint medium 2 is subjected to explosive joining to a low C stainless steel plate of base metal 1 and alloy Ti plates 3 are subjected to explosive joining thereon. Further, the two Ti plates thicker than the first layer Ti plate are subjected to explosive joining in order. At the time of explosive joining of the Ti plates 3 of the second and subsequent layers, heat treatment to soften the joining interface between the Ti plates and the stainless steel plate which are subjected to explosive joining is carried out. The above-mentioned heat treatment is carried out at the temperature in which Ta and stainless steel are not diffused mutually substantially and in addition, in Ar where Ti and Ta are not oxidized. The heat treatment is carried out when every explosive joining is finished.
