ASME SB338 Gr.7 Titanium Alloy Seamless Tube Applied for Heat Exchanger and Boiler
Titanium Alloy Tubes in ASME SB / ASTM B388 in Grade 1, 2, 5, 7, 9, 12, etc. Certified and Tested in accordance with Hardness Test, Hydrostatic Test, Eddy Current test, Eddy Current, Tensile Test, Flattening, Flare Test, Annealed, Hydrostatic Test, Tempered, Stress Relieved etc.
Titanium pipe and Tube is increasingly being used in a myriad of applications due to the inefficiency of stainless steel and other materials in many instances. A common titanium mill product is titanium tubes, which are employed in a variety of products owing to its superior corrosion resistance and strength-to-weight ratio. The development of many different alloys has extended the application of titanium in industries ranging from industrial and chemical processing to power generation.
The American Society of Mechanical Engineers has approved most titanium grades, meaning that more options are available for various projects. Although grades such as 1, 2, 3, 7, 9, 11 and others are usable, grade 2 is suitable for most instances. The ready availability of grade 2 makes it a preferable material for quick production runs and larger orders.
Determining how a grade will exactly be used is essential prior to selecting any grade. Grades 7, 12, 16, or 26 can be used to fabricate titanium pipes for use in areas demanding greater corrosion resistance. Grades 3 and 12 may be a preferable material for pipes requiring more strength.
