Daxun Alloy's pure titanium Grade 1 titanium tubes include:
seamless titanium tubes and welded titanium tubes, which have outstanding ductility and cold formability, making them perfect for deep drawing applications. Grade 1 titanium tubes are celebrated for their exceptional general and seawater corrosion resistance. They also exhibit remarkable resistance to oxidizing, neutral, and slightly reducing environments (solutions) including chlorides.
Titanium's low density (approximately half that of nickel-based alloys), combined with its high strength, lightweight nature, and superior corrosion resistance, makes it an unparalleled choice for demanding chemical conditions. Our execution standards include ASTM B338, ASTM B265, ASME SB265, ASTM F67, ISO 5832-2, 3.7025, and UNS R50250.
Grade 2 Titanium Tube (UNS R50400 / Werkstoff WS 3.7034)
Renowned as the most commonly used titanium tube for industrial purposes, Grade 2 offers an excellent balance of moderate strength and reasonable ductility. It provides outstanding corrosion resistance in both highly oxidizing and slightly reducing conditions, including chlorides. This grade is extensively used in the chemical and offshore industries, as well as in aircraft manufacturing where strength and ease of forming are crucial. Moreover, it finds applications in heat exchangers, hypochlorite systems, fire water systems, ballast water systems, industrial and aerospace components, CPI equipment, and piping systems.
Fabrication
Titanium Grade 2 responds exceptionally well to cold forming using standard methods. It can be easily machined, although it's critical to maintain sharp tools and use liberal amounts of coolant. Similar to machining austenitic stainless steels, the cuts should be deep and continuous with slow feeds and speeds.
Stock Availability
Daxun Alloys maintains a robust inventory of CP 2 Grade Titanium Seamless and Welded Pipes in a range of sizes to meet diverse requirements.
Weight Reduction
CP 2 grade titanium tubes offer a remarkable low density and a high strength-to-weight ratio, making them ideal for applications necessitating weight reduction without compromising overall strength. These tubes boast excellent cold formability, good ductility, and can be welded using conventional TIG and MIG processes, provided inert gas shielding is utilized to prevent embrittlement of the weld zone.
Crystal Structure
At room temperature, ASTM B338 Grade 2 titanium tube exhibits an alpha (hexagonal close-packed) crystal structure, akin to commercially pure titanium grades 1 and 3. Around 885°C (1625°F), it transitions to a beta (body-centered cubic) structure. This transformation temperature can vary based on the type and amount of impurities or alloying additions. Alloying elements also bifurcate the single temperature of equilibrium transformation into two zones: the alpha transformation zone below which the alloy remains all alpha, and the beta transformation zone above which the alloy is all beta. Between these zones, both alpha and beta forms coexist. Typical alpha and beta transformation temperatures for Grade 2 titanium are 890°C (1635°F) and 913°C (1675°F) respectively.
Grade 2 Titanium Seamless Pipe Manufacturing Process
Daxun's ASTM B338 Grade 2 titanium seamless tubes are meticulously crafted from hollow blanks through processes such as hot extrusion or oblique rolling and piercing, followed by multiple cold rolling processes. Throughout all manufacturing stages, seamless tubes must retain continuous perimeters. The primary manufacturing stages include: sponge titanium vacuum arc melting, ingot blanking to obtain hollow blanks, cleaning, cutting and feeding, hot extrusion, or oblique rolling and piercing, degreasing, drying cutting, online annealing and straightening, pickling, multiple cold rolling, degreasing, drying, vacuum annealing, straightening, cutting, pickling, final inspection, marking (DAXUN), and packaging.
Grade 2 Titanium Welded Pipe Manufacturing Process
Daxun's ASTM B338 Grade 2 Titanium Welded Pipe: Expertly crafted from annealed flat-rolled steel plates or strips, utilizing the state-of-the-art TIG automatic arc welding process. Our meticulous production process 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 a mandatory stress relief heat treatment post-forming and welding. Note that Daxun integrates filler materials during the welding process.
