D type welded condenser tube

The manufacturing method of the D type welded condenser tube is to make the aluminum strip into a flat strip, and then connect the edges through a high frequency welding process.The main difference between extruded condenser tube and high frequency welded condenser tube is that it can use multi-layer materials of different aluminum alloys. The cladding is widely used in tubes produced by heat exchangers to achieve furnace welding or flame brazing and to provide sacrificial corrosion resistance.We can provide short or long tubes, perfect round or D-shaped, ordinary tubes or ready-to-use tubes, including grooves, drill holes, baffles and welded connection blocks
