Import Astm B861 Gr2 Seamless Titanium Pipe — Buy in Bulk from Supplier in China

Baoji Mingkun Nonferrous Metal Co., Ltd. offers ASTM B861 Grade 2 seamless titanium pipe, a single-phase unalloyed titanium product valued for its excellent corrosion resistance and weldability in marine, chemical and power-generation systems. The seamless construction eliminates the longitudinal weld seam, providing uniform circumferential strength and removing a potential leak path in pressure piping. Grade 2 contains nominally 99.0% titanium with trace palladium-free composition, offering a minimum yield strength of 275 MPa and tensile strength of 345 MPa in the standard annealed condition. The pipe conforms to ASTM B861, which governs dimensions, tolerances and mechanical properties for seamless and welded titanium pipe.

The seamless manufacturing route typically involves extrusion or rotary piercing followed by cold pilgering and annealing, producing a fine-grained homogeneous microstructure with typical grain size ASTM 7 or finer. Standard dimensions follow ANSI B36.10/19 schedules sizes, with nominal pipe sizes from 1/8 inch to 24 inch NPS possible for Grade 2, though the exact size range from Baoji Mingkun should be confirmed. Typical wall thickness tolerance is +/- 12.5% under ASTM B861, with OD tolerance +/- 0.4 mm for pipe under 48.3 mm outside diameter. The standard specifies hydrostatic or non-destructive electric test as the leak-tightness verification method.

Buyers of this pipe include desalination plant contractors, offshore platform fabricators, chemical process licensors and exhaust-system manufacturers who need the formability of Grade 2 for complex bends and flares. The material accepts hot and cold forming readily, with typical bend radii of 2.5 times the OD for cold bending without annealing between stages. When negotiating with Baoji Mingkun, confirm the available NPS range, whether fixed or random lengths are supplied, and the type of end finish (plain, bevelled, or grooved) because these details are absent from the source data and affect installation cost and schedule.

Baoji Mingkun Nonferrous Metal Co., Ltd. is located at Guojia Burg., Baotai Road, East High-Tec Second Gaoxin Road, Weibin Zone, Baoji 721013, Shaanxi, China. The supplier carries an imported tier and harbor trust tier classification, with a 0.00% response rate and zero average response hours recorded on the platform. No information about the year of establishment, factory floor area, number of employees, annual turnover, or named export countries is available in the source data.

The address situates the company in Baoji's established titanium manufacturing corridor, which supports credible production capability but does not replace direct verification. Buyers should treat unverified claims about ISO certification or SGS approval with caution, because the listing source mentions these without providing certificate numbers or scope. We recommend requesting a current ISO 9001 certificate, a factory profile with main equipment list, and reference customers before committing to volume orders, particularly for projects requiring material-traceability documentation.
