Titanium Grade 4 Instrumentation Tubes are precision-engineered tubular products made from commercially pure titanium (UNS R50700), offering the highest strength among all CP (commercially pure) titanium grades. These tubes are specifically designed for applications that demand exceptional mechanical strength, high corrosion resistance, and reliable performance under pressure. Grade 4 titanium’s superior strength, combined with its excellent corrosion resistance, makes it ideal for instrumentation systems operating in harsh or corrosive environments.
These tubes are commonly used in aerospace, marine, chemical processing, and offshore oil and gas industries, where they serve in hydraulic and pneumatic control systems, instrumentation lines, pressure measurement systems, and heat exchanger assemblies. The combination of seamless or welded construction, tight dimensional tolerances, and compliance with standards like ASTM B338 and ASTM B861 ensures the tubes are suitable for mission-critical applications where reliability and precision are essential.
One of the most important features of Titanium Grade 4 is its ability to withstand aggressive media such as chlorides, brine, seawater, and oxidizing chemicals. The stable and passive oxide film that forms on the titanium surface protects it from corrosion and pitting, even in high-stress environments. This corrosion resistance makes the tubes ideal for use in offshore platforms, chemical reactors, and environmentally demanding fluid systems.
Despite its high strength, Titanium Grade 4 maintains reasonable formability and weldability, allowing it to be shaped, bent, or welded using appropriate techniques under clean, inert conditions. Its non-magnetic and biocompatible properties also make it useful in specialized applications such as medical instrumentation and aerospace fluid systems, where material stability and cleanliness are paramount.

❓ Frequently Asked Questions (FAQs)
Q1: What is Titanium Grade 4, and how is it used in instrumentation tubes?
Titanium Grade 4 (UNS R50700) is the strongest of the commercially pure titanium grades. It is used in instrumentation tubes for high-pressure, high-strength applications where corrosion resistance and mechanical durability are critical—such as in offshore platforms, aerospace systems, and chemical processing plants.
Q2: How does Titanium Grade 4 differ from Grades 1, 2, and 3?
Titanium Grade 4 offers higher tensile and yield strength than Grades 1–3 due to its increased oxygen and iron content. However, it has slightly reduced formability and weldability compared to lower grades. It's ideal when strength is a primary requirement alongside corrosion resistance.
Q3: What standards do these tubes comply with?
Titanium Grade 4 instrumentation tubes are manufactured in accordance with standards such as ASTM B338, ASTM B861, ASTM B337, ASME SB338, and ASME SB861.
