Product Description
Ti6Al4V Gr5 Seamless Tube & ASTM B338 Grade 2 Solutions
Titanium and its alloys are high-performance metals capable of withstanding extreme temperatures. ASTM B338 specification covers approximately 28 grades of titanium alloys specifically designed for heat exchangers, surface condensers, and evaporators. The use of Titanium Heat Exchanger Tubes ensures product longevity and excellent performance in high-temperature applications.
Manufacturing involves producing seamless tubes from hollow billets through cold reducing or drawing processes. Alternatively, welded tubes are constructed using automatic arc welding. Welded tubes undergo cold working and heat treatment to transform the cast weld microstructure into a conventional equiaxed microstructure.
Frequently Asked Questions
Q1: What are the main applications for ASTM B338 titanium tubing?
ASTM B338 tubes are primarily used in surface condensers, evaporators, and heat exchangers due to their exceptional corrosion resistance and high temperature tolerance.
Q2: What is the difference between Grade 2 and Grade 5 titanium?
Grade 2 is commercially pure titanium offering excellent corrosion resistance and formability. Grade 5 (Ti-6Al-4V) is an alloy that provides much higher strength and can withstand higher operating temperatures.
Q3: Are these tubes suitable for automotive exhaust systems?
Yes, titanium tubing is highly sought after by performance street and race car fabricators for weight reduction and heat management in exhaust systems.
Q4: What testing procedures do the tubes undergo?
All products undergo rigorous testing including Ultrasonic tests, Radiography, Chemical/Mechanical analysis, and Positive Material Identification (PMI).
Q5: Can you provide customized lengths and end finishes?
Yes, we offer value-added services including cut-to-size, beveling, threading, polishing, and specialized coating services like epoxy or ceramic linings.
Q6: What are the typical delivery conditions for these tubes?
Tubes can be supplied in various conditions including Annealed and Pickled, Cold Drawn, Bright Annealed, or Hot Finished, depending on the specific grade and application requirement.
