Import Astm B862, Titanium Welded Pipes — Buy in Bulk from Supplier in China

ASTM B862 titanium welded pipes from Baoji Mingkun Nonferrous Metal Co., Ltd are produced to ASTM B/ASME SB861, ASTM B/ASME SB338, ASTM B/ASME SB523, ASTM B/ASME SB658, ASTM B/ASME SB161, ASTM B/ASME SB163, AMS 4942/4943, DIN and JIS standards. The material grades supplied include Gr.1, Gr.2, Gr.3, Gr.5, Gr.9, Gr.12 and Zr 702. These are commercially pure and alloyed titanium grades used across chemical processing, marine engineering and power generation sectors where corrosion resistance and strength-to-weight ratio are critical. The pipes are welded construction, distinct from seamless alternatives, offering cost advantages in larger diameters and longer lengths for less cyclic领悟 pressure applications.

The material grades available span unalloyed titanium (Gr.1, Gr.2, Gr.3) with varying oxygen and iron contents affecting yield strength, through alpha-beta alloy Gr.5 (Ti-6Al-4V) with 120 ksi minimum yield strength, to the near-alpha alloy Gr.9 (Ti-3Al-2.5V) and the corrosion-resistant Gr.12 (Ti-0.3Mo-0.8Ni). Zr 702 is zirconium alloy, often specified for extreme reducing acid environments. Welded titanium pipe manufacture typically involves cold forming of strip into cylinder, followed by TIG or plasma arc welding with autogenous or filler metal addition, then full annealing to restore corrosion resistance in the heat-affected zone. Standard surface finishes include pickled, bright annealed, or machined, depending on service requirements.

Buyers span chemical plant operators needing Gr.2 piping for chlorine service, desalination contractors specifying Gr.2 for seawater intake lines, and aerospace subcontractors requiring Gr.5 welded ducting. The supplier is located in Baoji, Shaanxi province, a recognised Chinese titanium production hub with concentration of sponge producers and fabricators. ASTM B862 specifically covers titanium and titanium alloy welded pipe for general corrosion-resisting and elevated-temperature service. Importers should confirm welding procedure qualifications, radiographic or ultrasonic testing levels, and whether supplementary leak testing to ASTM E340 is applied. Material test certificates to EN 10204 3.1 or 3.2 should be requested for traceability to the specific melt and mechanical property validation.

Baoji Mingkun Nonferrous Metal Co., Ltd is based at Dongxing Industry Garden, Baoji 721013, Shaanxi Province, China. Baoji city is established as one of China's primary titanium industry clusters, with proximity to domestic titanium sponge production and extensive downstream fabrication infrastructure. The supplier's tier is marked as 'imported' with a 'harbor' trust classification. The response rate is recorded at 0.00% with zero average response hours, indicating no historical response data is available through the platform. No information is provided regarding specific factory certifications, production capacity, years in operation, or export licence details in the listing source.

The company offers titanium and zirconium alloy products across multiple international standards including ASTM, ASME, AMS, DIN and JIS, suggesting experience with export-oriented specification compliance. The material grade range from commercially pure Gr.1 through to high-strength Gr.5 and specialised Zr 702 indicates capability across standard and niche alloy supply. Buyers should independently verify the supplier's ISO 9001 or AS9100 quality system status, welding procedure qualifications to ASME IX, and whether material test certificates are issued direct from the mill or through third-party inspection. The Shaanxi location offers logistical access to Xi'an Xianyang International Airport and overland freight routes to major Chinese ports including Shanghai and Tianjin.
