Adherence to execution standards such as ASTM B338, ASTM B265, ASME SB265, ASTM F67, ISO 5832-2, 3.7025, and UNS R50250 ensures top-grade quality and reliability.
Grade 2 Titanium Tube (UNS R50400 / Werkstoff WS 3.7034)
A Favorite in Industrial Applications: Grade 2 titanium tubes are highly sought after for their balanced mix of moderate strength and remarkable ductility. They offer unparalleled corrosion resistance in both highly oxidizing and slightly reducing conditions, including chlorides. Widely used across the chemical, offshore, and aerospace industries, these tubes excel in strength and formability, making them essential in heat exchangers, hypochlorite systems, fire water systems, ballast water systems, CPI equipment, and more.
Fabrication
Grade 2 Titanium's Workability: This metal demonstrates a robust response to cold forming using standard techniques. Machining is straightforward, provided sharp tools are maintained, and liberal coolant is used. Similar to austenitic stainless steels, deep and continuous cuts with slow feeds and speeds are recommended.
Stock Availability
Extensive Inventory: Daxun Alloys offers a comprehensive range of CP 2 Grade Titanium Seamless and Welded Pipes in diverse sizes, ensuring availability for varying industrial needs.
Weight Reduction
Effortless Strength and Agility: CP 2 grade titanium tubes boast a low density and a high strength-to-weight ratio, making them ideal for applications demanding weight reduction without compromising strength. These tubes are cold formable, exhibit excellent ductility, and can be welded using conventional TIG and MIG processes, with inert gas shielding to prevent weld zone embrittlement.
Crystal Structure
Intricate Crystal Dynamics: At room temperature, ASTM B338 Grade 2 titanium tubes exhibit an alpha (hexagonal close-packed) crystal structure, akin to commercially pure titanium grades 1 and 3. At around 885°C (1625°F), the structure transitions to beta (body-centered cubic). The transformation temperature can vary based on impurities or alloying elements, which also divide the single transformation temperature into alpha and beta zones, with typical transformation temperatures being approximately 890°C (1635°F) for alpha and 913°C (1675°F) for beta.
Grade 2 Titanium Seamless Pipe Manufacturing Process
Precision Engineering: Daxun's ASTM B338 Grade 2 titanium seamless tubes are meticulously crafted from hollow blanks via hot extrusion or oblique rolling and piercing processes, followed by multiple cold rolling stages. The manufacturing process ensures continuous perimeters at every stage, encompassing sponge titanium vacuum arc melting, ingot blanking, hot extrusion or oblique rolling and piercing, degreasing, drying, online annealing, straightening, and final inspection, marking, and packaging.
Grade 2 Titanium Welded Pipe Manufacturing Process
Daxun's ASTM B338 Grade 2 titanium welded pipe is meticulously crafted from annealed flat-rolled steel plate or steel strip employing an advanced automatic arc welding (TIG) process. The comprehensive production journey encompasses: titanium plate uncoiling, shearing, butt welding, cleaning, pipe forming, TIG welding, eddy current testing, pre-sizing, annealing, precision reducing and sizing, straightening, eddy current testing, caliper marking, cutting, ultrasonic testing, hydrostatic testing, final inspection, and packaging. Each welded pipe undergoes at least one stress relief heat treatment post forming and welding. At Daxun, no filler materials are utilized during the welding process, ensuring superior quality and integrity.
Ti-6Al-4V Titanium Pipe - Grade 5 Titanium Tube
Titanium Alloy - (UNS R56400)
Introduction
DAXUN Ti-6Al-4V Titanium Tube, Grade 5 (UNS R56400), stands as the pinnacle of titanium alloys. This alpha+beta titanium alloy, fortified with aluminum as the alpha stabilizer and vanadium as the beta stabilizer, boasts exceptional high-strength capabilities. It performs remarkably well at temperatures as low as 800°F (427°C).
