Import Astmb68 Standard Condenser Tube — Buy in wholesale FOB from Supplier in China

ASTMB68 seamless copper condenser tubes from Segment Industrial Development Co., Ltd. are drawn from deoxidized copper Cu-DHP with a minimum purity of 99.90%, conforming to the ASTM B68 standard for seamless copper tube used in pressure applications. The tubes feature washed and clean surfaces as supplied, with bundle packaging standard for ocean freight export from Jiangyin port in Jiangsu Province. These tubes serve heat exchanger builders, HVAC contractors, refrigeration equipment manufacturers, and power plant condenser specialists who require verified thermal conductivity and dimensional repeatability in cooling system tubing.

The Cu-DHP material designation indicates phosphorus-deoxidized copper, a grade selected specifically for its resistance to hydrogen embrittlement during brazing and welding, a critical property for condenser assembly. ASTM B68 governs wall thickness tolerances, out-of-roundness limits, and temper requirements (typically soft annealed or light drawn), though the exact temper and dimensional schedule for this listing should be confirmed directly with the supplier. Standard industry practice for such tubes includes lengths from 3 to 6 metres, outer diameters from 6.35 mm to 114.3 mm, and wall thicknesses from 0.5 mm to 3.0 mm, though these ranges are typical and not specific to this supplier's current stock.

Buyers typically specify these tubes for shell-and-tube heat exchangers, evaporator coils, and surface condensers where copper's thermal conductivity of approximately 390 W/m·K outperforms alternative materials. The Jiangyin manufacturing base in Jiangsu Province sits within China's concentrated copper semi-fabricated products cluster, with port access through Shanghai or Ningbo for containerised export. Segment Industrial Development Co., Ltd. holds harbor-tier platform standing, though prospective importers should note the published response rate of 0.00% and plan direct outreach to confirm current availability, mill test certificate provision, and exact dimensional schedules.

Segment Industrial Development Co., Ltd. is located at No.59, Hongqi Road, Huashi, Jiangyin, Jiangsu Province, China, postal code 214400. The company holds harbor-tier standing on the sourcing platform, which represents a baseline verification level. The published response rate shows 0.00% with an average response time of zero hours, indicating that automated or recent engagement metrics are not available, and direct contact will be essential for any procurement discussion. The listing itself provides limited corporate narrative, concentrating instead on product specifications and material grades.

The supplier's geographic position fictional in Jiangyin positions it within one of China's principal clusters for copper and copper-alloy semi-fabricated products, with established supply chains for copper cathode through to finished tube. No information is provided on company history, ownership structure, production capacity, annual revenue, or major clients, and these details are not fabricated here. Buyers should request a company profile, ISO 9001 certificate status, and references to recent export shipments when conducting due diligence. The absence of claimed certifications in the source data means none are stated or implied in this description.
