从China供应商批发进口304 /316 Small Diameter Seamless Pipe — FOB条款

This small diameter seamless pipe is manufactured in corrosion-resistant stainless steel grades 304 and 316, meeting ASTM A312 standards for seamless and welded austenitic pipe. The dual-grade offering allows buyers to select 304 for general corrosive environments or 316 for enhanced chloride resistance in marine and chemical applications. These tubes are produced to precise dimensional tolerances required in petrochemical, food processing, pharmaceutical, and chemical industries.

Grade 304 contains 18% chromium and 8% nickel typical, while 316 adds 2-3% molybdenum for superior pitting resistance. The seamless construction eliminates weld seam weakness, providing uniform wall thickness and pressure ratings across the entire length. Austenitic structure delivers excellent toughness and oxidation resistance at elevated temperatures, with typical service range from cryogenic to 870 degrees Celsius intermittent. Surface finish options typically include pickled, annealed, or passivated conditions depending on end-use requirements.

Industrial buyers source this pipe for heat exchanger tubing, instrumentation lines, hydraulic systems, and process piping where leak integrity is critical. Food and pharmaceutical sectors require the sanitary surface finish achievable with seamless construction. Importers should confirm whether Wuxi Longwei Precision Tube Co., Ltd. supplies mill test certificates with chemical composition and mechanical test results, as ASTM A312 compliance documentation varies by order volume and destination market requirements.

Wuxi Longwei Precision Tube Co., Ltd. is located at Yaxi Industrial Park, Luoshe Town, Wuxi, Jiangsu Province, China, postal code 214187. The company operates under a harbor trust tier classification within the marketplace. The response rate is recorded at 0.00% with zero average response hours, indicating limited or no recent engagement data is available through the platform.

The supplier's product focus centres on precision tube manufacturing in stainless steel grades 304 and 316, positioned for industrial B2B export markets. No verified certifications, production capacity figures, year of establishment, or client references are stated in the available profile data. The company name suggests specialisation in precision-drawn or cold-finished tubing rather than large-diameter welded pipe. Importers are advised to request factory audit reports, ISO 9001 certification status, and sample qualification data before committing to bulk orders.
