Titanium welded tube are made by selecting high-quality cold-rolled titanium plates of suitable thickness, flattening, cutting and cleaning, then rolling the titanium plates into tubes and welding them by fully automatic welding equipment. Our advanced welding equipment ensures the quality of welding. Ultimately it helps to produce high-quality titanium tubes.
