Import 904l Stainless Steel Seamless Pipe — Buy in Bulk from Supplier in China

904L stainless steel seamless pipe is a super austenitic grade manufactured without longitudinal weld seam, offering uniform mechanical properties and enhanced pressure containment capability. The pipe conforms to ASTM A312 and ASTM A213 specifications, lineup standards for seamless, welded, and heavily cold worked austenitic stainless steel pipes and seamless austenitic boiler tubes respectively. Its seamless construction eliminates weld zone vulnerability, making it suitable for high-pressure and high-temperature service in chemical processing, marine, oil and gas, pharmaceutical and wastewater management applications. The 904L composition delivers superior resistance to pitting and crevice corrosion compared with standard 316L, driven by elevated nickel and chromium levels combined with strategic copper addition.

The material's resistance to chloride-induced corrosion cracking extends service life in aggressive environments including seawater cooling systems and acid chemical transfer. Seamless manufacture via hot extrusion or piercing ensures consistent wall thickness and grain structure throughout the circumference. Available dimensions cover various diameters and wall thicknesses to match project requirements, though the listing does not specify exact size ranges. Surface condition is typically pickled and passivated or cold finished, depending on order specification. The grade maintains austenitic stability across cryogenic to elevated temperatures, with good weldability using matching filler metals for field fabrication.

Primary applications include chemical process piping, offshore platform risers and process lines, pharmaceutical sterile fluid systems, heat exchanger tubing, and high-temperature exhaust systems. Buyers span EPC contractors, refinery operators, shipyards, desalination plant engineers, and API-licensed fabricators. The supplier indicates flexible minimum order quantities and offers FOB and CIF shipping terms. Certification to ISO and CE standards is referenced, though specific certificate numbers and accredited bodies are not stated. Buyers should confirm exact alloy composition, mechanical test results, and hydrostatic test pressures for their specific pipe schedule and application code requirements.

Baolai Steel Group Co., Ltd. is headquartered at 10th Floor, 321 Buildinguite Building, Xinchengnandu, Hutang Town, Wujin District, Changzhou 213161, Jiangsu Province, China. The company holds imported supplier tier classification with harbour trust status. No response rate or average response time data is available. The physical address in Changzhou, a major steel processing and distribution hub in the Yangtze River Delta, suggests proximity to mills, ports and logistics infrastructure. The company does not disclose founding year, workforce size, annual turnover, named clientele, or factory ownership status in its profile.

The listing emphasises engineering and quality assurance for corrosive service applications, with reference to ASTM compliance and international shipping capability. No specific production capacity, inventory levels, or lead time commitments are stated. Buyers should verify whether Baolai operates as a mill, stockist, or trading company, as this affects warranty, traceability, and technical support. The profile does not list ISO certificate numbers, CE marking notified body, or API licence details, so direct verification of certification validity is essential. The company's stated flexibility on MOQ may indicate stockholding or mill relationship, but this requires confirmation.
