Titanium Welded Pipe TIG Longitudinal ASTM B862

Titanium Welded Pipe TIG Longitudinal ASTM B862

Titanium welded pipe, also known as welded tube, is made from titanium coil that is formed and longitudinally welded into a pipe. This welded titanium tube is supplied to ASTM B862 and AMS 4941 and is widely used in the chemical industry and in sea water desalination. Because the tube is processed from titanium coil and welded lengthwise by the TIG process without metal filler, the homogeneity of the welded area is guaranteed; the even wall thickness means each part of the tube keeps the same mechanical properties as the initial coil. For these reasons more and more process equipment manufacturers choose the titanium welded tube instead of a seamless tube for their projects. Grades Gr1 (TA1), Gr2 (TA2) and Gr12 (TA10) are available.

Advantages of the Welded Tube

The titanium welded tube is formed from titanium coil and joined lengthwise by TIG welding without a filler metal, which keeps the welded area homogeneous. Wall thickness is even along the length and every part of the tube keeps the same mechanical properties as the initial coil, so the tube performs consistently in heat transfer and fluid handling duty. Combined with the natural corrosion resistance of titanium in seawater and many chemicals, this makes the welded pipe a practical and economical choice for chemical plants and desalination systems. Sizes, lengths and grades can be produced to order.
