从China供应商批发进口316l Stainless Steel Pipe — FOB条款

Tianjin Binhai Guanghao Pipe Fitting Co., Ltd manufactures 316L stainless steel seamless pipe in Tianjin, China, with product conforming to ASTM, AISI, DIN, EN, GB, and JIS standards. The listing specifies 300 series grade 316L in round shape, available in 6-metre lengths with cold rolled and hot rolled technique options. Surface finishes include polish, No.1, 2B, and hairline, allowing selection based on application requirements from structural to decorative. The pipe is spiral welded in construction with ISO certification stated, positioning it for chemical processing, oil and gas, pharmaceutical, and marine industry procurement.

The 316L grade specified by this supplier contains the standard low-carbon austenitic composition with maximum 0.03% carbon, 16-18% chromium, 10-14% nickel, and 2-3% molybdenum. The seamless construction method (implied by the product name though welding line type is listed as spiral welded) typically offers superior pressure containment and absence of longitudinal weld seam weaknesses. Cold rolled pipe provides tighter dimensional tolerances, improved surface finish, and higher strength than hot rolled equivalents, while hot rolled product suits larger diameters and heavier wall sections where precision is less critical. The 6-metre standard length aligns with common Chinese mill practice and container shipping optimisation, though custom lengths may be negotiable for substantial orders.

Applications for this pipe span construction frameworks, process piping in chloride-exposed chemical plants, offshore platform piping, pharmaceutical cleanroom installations, and food processing equipment. The multiple surface finish options (polish for hygienic applications, 2B for general industrial, No.1 for high-temperature or abrasive environments, hairline for aesthetic architectural use) broaden the addressable market. Buyers should confirm which ASTM A312 or A213 variant applies to their specific order, whether the ISO certification covers quality management (ISO 9001) or product-specific standards, and whether the spiral welded designation applies to all sizes or only specific product lines. The Tianjin origin provides access to Xingang Port, one of China's busiest northern ports with established container and bulk shipping routes.

Tianjin Binhai Guanghao Pipe Fitting Co., Ltd operates from the New Industrial Zone of Binhai, Tianjin, China. The company holds a Harbor trust tier on the platform, with a response rate of 0.00% and zero average response hours recorded, indicating no platform-mediated communication history. The supplier profile does not disclose year of establishment, production capacity, annual turnover, employee numbers, or specific manufacturing equipment. The Binhai New Area location suggests industrial zone access with potential logistics advantages near Xingang Port, though buyers should verify actual facility ownership versus trading company status.

The product range implied by the company name includes pipe fittings as well as pipe, though the listing focuses on 316L stainless steel pipe. ISO certification is claimed without specifying ISO 9001, ISO 14001, or product-specific standards. No customer references, export experience details, or third-party audit information is provided. Given the multiple standard claims (ASTM, AISI, DIN, EN, GB, JIS), importers should request scope of certification documents and confirm which standards are covered by current mill production approval. Direct factory audit or video inspection is recommended before committing to first orders, particularly to reconcile the seamless product description with spiral welded welding line type specification.
