Import Astm B 338 Gr2 Gr5 Gr12 Titanium Seamless Tube — Buy in wholesale FOB from Supplier in China

Jiaping Titanium Industry Co., Ltd. manufactures titanium seamless tubes to ASTM B338 in grades Gr2, Gr5 and Gr12. Gr2 is unalloyed titanium with excellent corrosion resistance and formability. Gr5 (Ti-6Al-4V) is an alpha-beta alloy with yield strength around 880 MPa and tensile strength of 950 MPa, the most widely used titanium alloy in aerospace and chemical plant. Gr12 (Ti-0.3Mo-0.8Ni) offers improved crevice corrosion resistance in hot brines compared to Gr2, with better weldability than Gr5. The tubes are produced as seamless hollows for applications where weld integrity cannot be risked.

The standard specifies dimensions from 6.35 mm to 114.3 mm outside diameter, with wall thicknesses governed by purchaser agreement. Typical delivery conditions are annealed or cold-worked and stress-relieved. Surface finish is generally pickled or machined. Gr2 tubes are often specified for heat exchanger service in chloride environments where copper-nickel alloys would fail. Gr5 tubes suit pressure vessels and offshore risers where strength-to-weight ratio governs design. Gr12 finds niche use in power plant condensers and chemical process tubing where palladium-enhanced grades are cost-prohibitive.

Buyers in chemical processing, power generation and marine engineering source these tubes for shell-and-tube heat exchangers, surface condensers, evaporators and superheater coils. The supplier's location in Shenzhen, Guangdong places it near major southern Chinese ports for containerised or breakbulk shipment. All grades demand mill test certificates to ASTM B338 with actual chemistry, mechanical test results and ultrasonic test reports. Third-party inspection to ISO 17020 is advisable given the zero percent response rate recorded for this listing. Buyers should confirm whether Jiaping stocks semi-finished hollows or mills from billet, as this affects minimum order quantities and delivery schedules.

Jiaping Titanium Industry Co., Ltd. is located at Shiguan Industrial Park in Shenzhen, Guangdong Province, 518109, China. The company is classified as an imported-tier supplier with a harbour trust designation. The response rate stands at zero percent with no recorded average response hours, which indicates buyers should expect delayed or minimal communication and should plan sourcing timelines accordingly. The supplier lists titanium seamless and welded tubes for heat transfer and pressure equipment applications, with material grades spanning Gr1, Gr2, Gr5, Gr7, Gr9, Gr12 and Gr16.

The listing provides no information on year of establishment, production capacity, number of employees, revenue figures, or named clients. There is no mention of ISO 9001, ASME accreditation, NORSOK approval, or other third-party quality system certification. Buyers should request a current quality manual, evidence of ASTM B338 testing capability, and reference projects before committing to trial orders. The Shenzhen location offers proximity to Yantian and Shekou ports, which may reduce inland freight costs for export shipments compared to inland Chinese suppliers.
