ASTM B338 Titanium Heat Exchanger Tubes

Standard Specification for Titanium and Titanium Alloy Seamless Tubes for Heat Exchangers & Condensers

Standard Overview

ASTM B338 is a specialized ASTM International standard specifically for seamless titanium and titanium alloy tubes designed for heat exchanger, condenser, and thermal transfer applications. This standard is tailored to the unique requirements of heat transfer tubing, setting stricter requirements for surface quality, dimensional accuracy, corrosion resistance and heat transfer performance compared to general piping standards like ASTM B337.

ASTM B338 is the global benchmark for titanium heat exchanger tubes, ensuring optimal thermal conductivity and corrosion resistance for efficient heat transfer in harsh environments. BOZE Metal specializes in supplying ASTM B338 compliant seamless titanium tubes for heat exchanger and condenser manufacturing.

Standard Scope & Applicable Grades

ASTM B338 applies exclusively to seamless titanium tubes intended for heat exchangers, condensers, coolers and other thermal transfer equipment, focusing on high thermal conductivity and corrosion-resistant pure titanium grades.

• Primary Applicable Grades: Grade 1, Grade 2 (most common for heat exchangers), Grade 7, Grade 12

• Product Forms: Seamless titanium tubes, precision thin-walled heat exchanger tubes

• Application: Heat exchangers, condensers, evaporators, thermal transfer equipment

Key Heat Exchanger Tube Requirements
