1. Product Description
Copper clad steel tubesheet for pressure vessel saves a lot of precious metal copper, greatly reduces the cost, and gives full play to the excellent antifriction property of copper and the high strength performance of steel, improving the comprehensive mechanical properties of copper/steel composite workpieces. It has good economic benefits and a wide range of applications and also conforms to the resource-saving development direction of construction, so it has been developed rapidly.
2. Product Features
Copper has excellent ductility, antifriction, conductivity, and thermal conductivity. However, with the massive development and utilization of copper resources in recent years, its price has increased year by year; As steel is cheap and has high strength, it is a good choice to use copper/steel bimetal composite to replace single pure copper or copper alloy. Copper clad steel tubesheet for pressure vessel saves a lot of precious metal copper, greatly reduces the cost, and gives full play to the excellent antifriction property of copper and the high strength performance of steel, improves the comprehensive mechanical properties of copper/steel composite workpiece, has good economic benefits and a wide range of applications, and also conforms to the development direction of resource-saving construction.
3. FAQ
What is explosive welding?
Metal explosive welding is to use the high-strength chemical energy generated by the explosive explosion to drive the clad plate to impact the substrate at high speed. The instantaneous high pressure generated at the impact point not only destroys the oxide film on the surface of the metal plate, exposing the fresh surface but also forms a thin layer of welding transition zone with plastic deformation, melting, diffusion, and waveform characteristics on the exposed fresh metal surface, Therefore, it is a new metal welding process and technology to achieve strong solid bonding. According to the different installation forms of the clad plate and base plate, explosive welding can be divided into parallel methods and angle methods. When installing with the parallel method, the clad plate is parallel to the base plate, and the clearance h0 remains unchanged. The angle rule is that a certain angle is formed between the clad plate and the base plate α Install.
