Import Astm B338 Gr2 Seamless Pipes Made In China — Buy in wholesale FOB from Supplier in China

Carry Jin supplies ASTM B338 Grade 2 seamless titanium pipes from manufacturing roots in Shenyang, Liaoning Province, a centre of Chinese titanium production since the 1950s. Grade 2 titanium is the workhorse of the commercially pure grades, with minimum 99.2 percent titanium content, 0.25 percent maximum oxygen, and 0.30 percent maximum iron, delivering a balance of corrosion resistance and moderate strength that suits chemical processing and marine heat exchangers. ASTM B338 specifically covers seamless and welded titanium tubes for surface condensers, evaporators and heat exchangers, with Gr2 offering 275 MPa minimum yield strength in the annealed condition. The seamless construction eliminates the weld bead and heat-affected zone variability that can nucleate corrosion in chloride service.

Shenyang Daji Industrial Ltd., the production entity behind Carry Jin, operates from a 60,000 square metre site in Shenyang Economic and Technological Development Zone with 20,000 square metres of built production area. The facility lists 60 sets of production equipment and processes titanium and titanium alloys, nickel alloys, and related non-ferrous materials. Seamless Gr2 pipe is typically produced by pierce-and-roll or extrusion from ingot, followed by cold reduction and vacuum annealing to achieve the fine alpha microstructure that gives commercially pure titanium its characteristic ductility. Typical product forms include tubes from 6 mm to 114 mm outside diameter, with wall thicknesses from 0.5 mm to 5.0 mm, though buyers should confirm Carry Jin's exact dimensional range and whether they hold stock or produce to order.

The primary applications for B338 Gr2 seamless pipe include shell-and-tube heat exchangers in seawater desalination, chemical plant condensers, power station surface condensers, and offshore platform cooling systems. Gr2's corrosion resistance in seawater and brackish water, combined with its absence of toxicity to marine life, makes it preferable to copper-nickel alloys in environmentally sensitive installations. Carry Jin's listing indicates export to Russia, Singapore, Australia, South Korea and Japan, suggesting familiarity with varied national standards. Buyers should confirm which product standards are offered beyond ASTM B338, whether ASME SB338 or Russian GOST analogues are available, and request actual mill test certificates with tensile data, chemical analysis, and hydrostatic test results before finalising specifications.

Carry Jin operates through Shenyang Daji Industrial Ltd., founded in 1993 and headquartered in Shenyang's Metallurgical Industrial Park with two additional subsidiaries in Donggang and Changshu. The Shenyang parent facility covers approximately 60,000 square metres with 20,000 square metres of construction, housing 60 sets of production equipment. The company reports more than 100 employees including 20 with senior and medium technical titles, and cites an annual production value up to RMB 300 million, though buyers should treat self-reported figures as unverified claims requiring audit confirmation. The business exports to Russia, Singapore, Australia, South Korea and Japan according to its profile.

The supplier's trust tier is listed as harbor, with no response rate or response time data available, indicating no recent inquiry history on the platform. Carry Jin does not claim specific ISO, ASME or NORSOK certifications in the provided source material, though it references adherence to American, Russian, Japanese and Chinese standards. The company produces a broad range of titanium and nickel alloy products including wires, rods, plates and bars, so buyers of seamless pipe should confirm that dedicated tube mills and pilger reduction capacity exist rather than assuming seamless pipe is a core product. No client references, project lists, or third-party audit results are provided in the source profile.
