ASTM B337 Titanium Seamless and Welded Tubes

Standard Specification for Titanium and Titanium Alloy Seamless and Welded Tubes For Fluid Transport & Industrial Use

Standard Overview

ASTM B337 is an ASTM International standard covering seamless and welded titanium and titanium alloy tubes for general industrial, chemical processing, marine and heat exchange applications. This standard specifies requirements for titanium tubes used for fluid transport, pressure systems and general industrial piping, establishing guidelines for material quality, dimensional tolerances, mechanical properties and testing methods.

ASTM B337 ensures consistent performance of titanium tubes in corrosive and high-temperature environments, making it the primary standard for industrial titanium piping systems. BOZE Metal supplies ASTM B337 compliant titanium seamless and welded tubes, suitable for a wide range of fluid handling and industrial piping applications.

Standard Scope & Applicable Grades

ASTM B337 applies to both seamless and welded titanium tubes, available in annealed condition, covering commercially pure titanium and selected titanium alloy grades suitable for tubular products and piping systems.

• Applicable Grades: Grade 1, Grade 2, Grade 3, Grade 4, Grade 7, Grade 9, Grade 12

• Product Forms: Seamless titanium tubes, welded titanium tubes, straight tubing

• Application: General fluid transport, industrial piping, non-pressure fluid systems

Key Standard Requirements

• Chemical composition and mechanical property requirements for tube-grade titanium

• Dimensional tolerances for outer diameter, wall thickness, length and straightness

• Surface quality and internal cleanliness standards for tubular products

• Hydrostatic testing requirements for pressure integrity verification

• Welding quality standards for welded titanium tubes (where applicable)

• Non-destructive testing protocols for tube defect detection

Industrial Piping Applications

• Chemical Processing: Acid and corrosive fluid transport piping systems

• Marine Systems: Seawater piping, shipboard fluid transport lines

• Industrial Fluid Lines: General industrial fluid handling and process piping

• Environmental Systems: Desalination and water treatment fluid tubing
