Abstract
The utility model relates to the field of dedicated titanium-copper composite transition joints and discloses a dedicated titanium-copper composite transition joint. A titanium alloy tube is arranged at one end of the dedicated titanium-copper composite transition joint, a copper tube is arranged at the other end, and a titanium-copper composite tube is arranged in the middle. The titanium-copper composite tube is composed of a titanium alloy tube, a titanium-copper composite layer and a copper tube sequentially from the outer wall to the inner wall, wherein the titanium-copper composite layer is composed of titanium alloy and metallic copper which are formed by implementing an explosive cladding method after the titanium alloy tube and the copper tube are sleeved. According to the dedicated titanium-copper composite transition joint, the technical problems that traditional titanium-copper composite transition joints are low in the rate of finished products, leak easily and the like are solved, the manufactured dedicated titanium-copper composite transition joint are high in the bonding strength and the rate of finished products and capable of meeting domestic production use requirements for dedicated titanium-copper composite transition joints, changing the unfavorable situation that current high-quality dedicated titanium-copper composite transition joints highly depend on import and obtaining high market competitiveness and good economic benefits.
