Four processing methods of titanium welding pipe
Die-plate welded titanium pipe
Compared with the multi-seam "shrimp" type, the titanium pipe has less weld, but the more complex the pressing process, requires a lot of molds, consumes more materials and processes, the weld will also affect the corrosion resistance, the appearance is not ideal.
2.Multi-weld type (commonly known as " shrimp waist & quot; type) titanium pipe:
Its processing process is complex, usually using the pipe cut into multiple sections, welding or plate into multiple sections of expansion material, and then rolled welding, this method is more leftover material, large weld quantity. Because the weld will greatly reduce the corrosion resistance, easy leakage, and the appearance is not good, the inner surface is a folding surface, increase the pipeline transmission resistance and increase the erosion of the back and reduce the life.
3. Pashed titanium welded pipe:
The titanium tube appearance and push titanium tube seems to have no difference, but the processing process is the billet in the song stamping molding, titanium tube in the process of forming the back pull, and forced the back thin, inner wall compression and thickening caused uneven or wrinkle, and using titanium pipe back under erosion corrosion, because the back wall thin easy early damage, make the overall life of the pipe is greatly reduced.
4. Cast-type titanium pipe
Although it is no seam titanium pipe, but the wall thickness (at least 5mm) and the pipe wall thickness (2mm~4mm) can not match, thus increasing the transmission resistance, and the surface finish is poor, more importantly, there are a large number of internal stomata produced by the manufacturing defects, seriously affect the corrosion resistance and life.
