Astm Stainless Steel Heat Exchange Air Cooler Extruded Finned Tube
The integral finned tube is rolled from the thick wall seamless tube after heating. The finned tube and the base tube are the same metal body without defects such as desoldering and low tightness. Because the finned tube and base tube are the same metal body with low thermal resistance, the heat transfer efficiency is improved. The integrated finned tube has obtained the national patent, and the special equipment "hot rolling steel based finned tube processing machine tool" is used for the production of integrated finned tube.
