Titanium tube is under ASTM B337, ASTM B338, GB/T3624, GB/T26057 and GB/T26058 standard. The grade includes Gr1,Gr2,Gr3,Gr5,Gr7,Gr12, TA1,TA2,TA3,TA9,TA10 and TC4. The tube includes pure titanium tube, titanium alloy tube and titanium nickel alloy tube, etc. There are two types of treatment fort option: annealing treatment and hot extrusion. According to production, there are also two types of tube: welded and seamless. And for seamless tube, we can provide tubes by hot extrusion production for multiple purposes and tubes by cold rolling production for general industrial purposes. Besides standard size, customized size order is acceptable as well.
