Asme SB338 Gr.7 Titanium Alloy Seamless Tube​

 

We are one of the biggest manufactures of stainless steel & duplex steel & alloy steel tubes and pipes in China. With development more than 20 years, we have accumulated a great many clients all around the world and Yuhong products also won the great praise among the customers.

 

ASME SB338 is the standard specification for seamless and welded titanium and titanium alloy tubes or tubing which are intended for surface condensers, evaporators, and heat exchangers. It is identical with ASTM B338 except for some minor difference in product marking. There are 28 grades of titanium and titanium alloys for tubing purpose, among which Titanium Grade 2, Grade 7 and Grade 12 are most often seen in tubing applications.

 

The titanium seamless tube shall be made from hollow billet by any cold drawing or cold reducing process with a continuous periphery in all stages of manufacturing operation. The titanium welded tube shall be made from annealed, flat-rolled plates by an automatic arc-welding or other welding process.
