Grade 1 titanium tubes offer outstanding general and seawater corrosion resistance along with exceptional resistance to oxidizing, neutral, and slightly reducing media (solutions), including chlorides.
Titanium's low density-about half that of nickel-based alloys-combined with its high strength, lightweight nature, and superior corrosion resistance, makes it an ideal choice for a variety of harsh chemical conditions. Compliant with execution standards: ASTM B338 | ASTM B265 | ASME SB265 | ASTM F67 | ISO 5832-2 | 3.7025 | UNS R50250.


Grade 2 Titanium Tube (UNS R50400 / Werkstoff WS 3.7034)

This is the most frequently used titanium tube for industrial applications, offering a superb balance of moderate strength and reasonable ductility. It delivers excellent corrosion resistance in both highly oxidizing and slightly reducing conditions, including chlorides. With its strong corrosion protection, it's an asset in the chemical and offshore industries, aircraft manufacturing, heat exchangers, hypochlorite systems, fire water systems, ballast water systems, industrial and aerospace components, CPI equipment, and piping solutions.

Fabrication

Titanium Grade 2 is highly responsive to cold forming using standard methods. It can be easily machined; however, it requires maintaining sharp tools and liberal use of coolants. Similar to machining austenitic stainless steels, cuts should be deep and continuous with slow feeds and speeds for optimal results.

Stock Availability

Daxun Alloys maintains a robust stock of CP 2 Grade Titanium Seamless and Welded Pipes in a range of sizes to meet various customer needs.

Weight Reduction

CP 2 grade titanium tubes boast low density and a high strength-to-weight ratio, ideal for applications where weight reduction is paramount without compromising strength. They are cold-formable, possess good ductility, and can be welded using conventional TIG and MIG processes, though inert gas shielding is essential 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. At approximately 885°C [1625°F], it transitions to a beta (body-centered cubic) structure. This transformation temperature can vary with impurities or alloying additions. Alloying elements also divide the single equilibrium transformation temperature 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 crafted from hollow blanks through hot extrusion or oblique rolling and piercing, followed by multiple cold rolling processes. At every stage, titanium seamless tubes must have continuous perimeters. The manufacturing process includes: sponge titanium vacuum arc melting, ingot blanking to hollow blanks, cleaning, cutting, 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 is meticulously crafted from annealed flat-rolled steel plate or steel strip via the advanced automatic arc welding (TIG) process. The comprehensive production stages encompass: titanium plate uncoiling, precise shearing, seamless butt welding, thorough cleaning, innovative pipe forming, sophisticated TIG welding, stringent eddy current testing, accurate pre-sizing, controlled annealing, precision reducing and sizing, meticulous straightening, additional eddy current testing, caliper marking, precise cutting, comprehensive ultrasonic testing, rigorous hydrostatic testing, final inspection, and premium packaging. Each welded pipe undergoes mandatory stress relief heat treatment post forming and welding, ensuring superior performance. Notably, Daxun refrains from using any filler materials during the welding process, maintaining the utmost purity and integrity of the titanium pipe.
