Import 316l Stainless Steel Pipe Or Tube — Buy in wholesale FOB from Supplier in China

Zhejiang Qiangli Stainless Steel Manufacture Co., Ltd produces 316L stainless steel pipe and tube from Songyang County, Lishui, Zhejiang, China, targeting chemical processing, marine, pharmaceutical, and food processing applications where corrosion resistance in chloride-bearing environments is critical. The material is low-carbon 316L, specifically selected to reduce carbide precipitation during welding. The supplier cites ASTM A312 compliance and offers schedules from 5S through 80S, indicating coverage of both light-wall instrumentation tubing and heavier process piping. Seamless construction is featured as the primary product form, enhancing structural integrity under internal pressure.

The low carbon content of 316L (maximum 0.03 percent carbon) distinguishes it from standard 316, preserving intergranular corrosion resistance in the heat-affected zone after welding without requiring post-weld heat treatment. This property is essential for pharmaceutical and food-grade installations where weld integrity must withstand aggressive cleaning cycles and chloride exposure. The seamless manufacturing process, likely cold-drawn or extruded and followed by solution annealing, yields uniform grain structure and consistent mechanical properties circumferentially. Typical applications include process piping for acids and alkalis, heat exchanger tubing, marine hardware, and hygienic pipelines where CIP (clean-in-place) and SIP (sterilise-in-place) protocols apply.

Buyers include chemical plant engineers, marine equipment fabricators, pharmaceutical facility constructors, and food processing equipment OEMs. The supplier states flexible minimum order quantities without specifying values, and mentions ISO and SGS certifications without providing certificate numbers or scope. Shipping terms include FOB and CIF. The listing emphasises global sourcing from India, China, and South Korea as context for 316L availability, but the specific supply originates from the Zhejiang factory. Lead times, exact MOQ, and pricing are not disclosed and require direct confirmation with Zhejiang Qiangli Stainless Steel Manufacture Co., Ltd.

Zhejiang Qiangli Stainless Steel Manufacture Co., Ltd is located at No.209 Ruiyang Road, Xiping Industrial Zone, Songyang County, Lishui, 323400, Zhejiang, China. The supplier is classified within the "imported" tier and holds a "harbor" trust designation. Response metrics show 0.00 percent response rate and zero average response hours, indicating no platform-mediated buyer communication has occurred or been recorded. The industrial zone location in Songyang County suggests a manufacturing base within Lishui's metal products cluster, though the listing does not confirm owned production facilities versus trading operations.

The company profile presented in the source material contains no information about year of establishment, registered capital, factory area, employee count, annual output capacity, or named domestic or international clients. No specific ISO certificates (such as ISO 9001, ISO 14001, or ISO 13485 for medical devices) are identified by number or scope. The SGS mention lacks context, whether referring to factory audit, product testing, or system certification. The supplier's claimed market coverage includes chemical, marine, pharmaceutical, and food sectors, but no sector-specific qualifications (such as ASME BPVC for pressure vessels or 3-A Sanitary Standards for dairy) are stated. Buyers should conduct independent verification of manufacturing capability and quality system validity before qualifying this supplier.
