ASTM A312 TP316Ti Stainless Steel Seamless Pipe for Chemical and Process Equipment

ASTM A312 TP316Ti seamless pipe is manufactured from UNS S31635 / EN 1.4571 titanium-stabilized austenitic stainless steel. This grade combines the corrosion-resistant characteristics of the 316 family with titanium stabilization for applications involving thermal exposure and welded fabrication.

ASTM A312 covers seamless, welded, and heavily cold-worked austenitic stainless steel pipe intended for high-temperature and general corrosive service. The specification includes requirements for chemical composition, mechanical properties, heat treatment, flattening, and hydrostatic or nondestructive electric testing.

TP316Ti is commonly specified for chemical process piping, petrochemical equipment, marine systems, heat-transfer equipment, and other industrial applications where corrosion resistance and material stability under elevated-temperature conditions are essential.

TP316Ti seamless pipe can be incorporated into:

• Shell and Tube Heat Exchangers
• Process Coolers
• Condensers
• Chemical Process Skids
• Storage and Transfer Systems
• Marine Piping Assemblies
• Process Utility Lines
• Chemical Processing Equipment

Typical dimensional controls include:

• Outside Diameter
• Wall Thickness
• Ovality
• Straightness
• Length
• End Squareness
• Surface Condition
• Schedule
• Pipe Weight

Dimensions can be supplied according to the applicable piping standard, project drawings, or purchase specification. ASTM A312 also references standardized stainless steel pipe dimensions associated with ASME B36.19.

Available inspection documentation may include:

ASTM A312 requires mechanical testing and specifies hydrostatic or nondestructive electric testing for each pipe.
