Explosive welding cladding tubesheet for condenser heat Exchanger

Mar 11, 2023

As a complete set of equipment, heat exchanger is one of the most typical products. It uses the explosive welding technology of sheet metal and tube, and the explosive welding technology of tube and tubesheet. This technological improvement can be summarized into five major advantages:

1. Using explosive welding cladding tubesheet instead of common carbon steel to manufacture condenser heat exchanger can ficantly improve the service life of equipment, improve the quality of products and ensure normal production.
2. Replacing pure precious metals with explosive welding cladding tubesheet can save a lot of rare metals and reduce the cost of equipment.
3. Using explosive plus rolling process instead of pure rolling process to manufacture bimetallic tubes, which can be used as heat exchanger bundles, can ficantly improve the heat transfer efficiency.
4. Explosive welding can improve the reliability of sealing and reduce physical labor compared with mechanical expansion.
5. The application of explosive welding cladding tubesheet not only makes it possible to require the pipe head and shell to resist the corrosion of different media, but also makes it possible to use different materials for the pipe head and shell respectively. This not only helps to avoid electrochemical corrosion, but also facilitates the use of welding structure between cylinder and tube sheet without flange connection.
